except from what i know and maybe you can prove this wrong covid cant penetrate the skin so why does the immune system need a boost when the vaccines use oil in them and that got proven to cause all types of health issues and information from 2013 and before proves that
@@jjcarvin4755 Only AND ONLY if you are here to be convinced otherwise, read on. Otherwise ignore the explanation. Covid doesn't penetrate our skin, yes. Our outsides are secure. BUT our INSIDES are not. Think of the skin as a shield...whats on the other end of it - the fragile human that can't take a sword to his chest. Covid gets inside our bodies through inhaling droplets that carry it. People sneezing or breathing creates those droplets. The more droplets from someone infected, and the further he is down the infection path, the higher number of covid cells do we inhale. New covid mutations currently are waaaaaaay more infectious. The virus can replicate faster and in turn drop you faster. And to top it all off...it acts like a hidden time bomb. You don't notice it until one day you can't fully breathe. The fun part starts here - covid can travel to the kidneys, liver, lungs, brain, gut. If your blood is thick and you begin treatment, said treatment includes antibiotics which dilute your blood. Any trombs that were stuck to your vein walls are now floating about, and will 100% create heart failure. Aspirin protect helps with keeping your blood diluted. Blood highways should not have solid particles in them like trombs or cholesterol buildup. Stay safe and healthy! :)

@@jjcarvin4755 Why does it affect the brain you may ask - because of one of our sinus caves. Leading vertically up to a thin wall/membrane. We have plenty of sinus caves in our skull you can check them out its kinda cool. How does it get to liver, kidneys - after traveling to the gut and moving onward for nutrient processing, those two create blood pressure chemicals from stress or some other ailment. Covid can attach itself to the types of cells that create the cortisol (i think thats what the blood pressure biochemical we produce is called). Keeping normal blood pressure is also beneficial. Furthermore, people have all sorts of illnesses they don't feel or know about. Covid can and WILL trigger something else if you catch it. Athletes have caught it. 20-30 y/o have had it. Some have survived and some sadly haven't. Another important thing. Kids have low percent chance of getting hit bt covid, but the cruicial part everyone seems to forget constantly is that they can transmit it to their parents and teachers. Covid can live ontop copper for a day. It can live on porous surfaces for up to 72 hours and more in some cases. You think an oily teenager skin isn't the perfect surface for covid to live on? He then touches everything his parents touch. Reported PROVEN cases plethora are out there of this exact thing happening. Yet the mass overlooks it because its simply tired. This entire thing can disappear if every human being stops gathering with people for 2 months. Covid lives for 1 month. And 1 more month for later cobtracted cases just to be sure. This entire scharade could have been nonexistent IF people don't have snowflake issues with a piece of cloth on their face for THEIR OWN GOOD...its like sueing doctors for putting a sleep gas mask on your face before surgery.

I didn't notice that! I did see that it is the only one of the big four vaccine companies who had a big gain during the pandemic. Selling for $19 last February, they reached $67 in October. $183 by February, they have seen profits taken down to the $155 level today. The amazing thing is to understand this is just the birth of a medical revolution, the DNA/RNA therapies. I don't know the next step but all the steps will be amazing.
It's true. Did you also know Moderna was founded on the discovery of mRNA and they have never developed a vaccine? They just call it a vaccine for their benefit, not yours or mine.
COVID-19 vaccines are new, and it’s normal for people to have questions about them. The sheer amount of information-and misinformation-about the different vaccines can be overwhelming to anyone. It's nice to see that SciShow is providing well-researched information (in snackable length) about this important topic.
Not true. Vaccines are a tried and well understood technology. However Pfizer, Moderna, J&J or AstraZeneca products are not vaccines but a gene therapy. Thank you, I will pass on that.
@@franklinAll8735 How proudly misinformed you are is proved by fact that some of the vaccines you mentioned use the traditional method, not mRNA. As explicitly mentioned in the video for the uneducated, mRNA vaccines are in no way a form of gene therapy. In fact, so far the evidence shows that they are the safer alternative.
@@Theo0x89 Before trying to lecture someone do some research because now you look silly. Traditional method would be to inject weakened, inactivated or part of the covid virus so that the body could recognize the virus and develop natural immunity. None of the 'vaccines' I mentioned do that. They all deliver a set of instruction to the host cell and the very host produces the coronavirus spike protein. The difference between pfizer/moderna and astrazeneca/JJ is only the delivery vehicle. Former use nanoparticles to enter the cell and deliver instructions(mRNA) while the latter use a modified chimpanzee adenovirus to infiltrate the cell and injects its DNA into the nucleus. That is a gene therapy. It does not change dna pressumably (which is theoretically possible with adenovirus vectors) but the effect is exactly the same. Your body is instructed to produce whatever foreign proteins are encoded on the mRNA / viral DNA. You sir, are an ignorant sheep, an exemplary soviet citizen, who would inject whatever the big daddy governments wants you to and you will very likely pay dire consequences of your choices in the future.
@@franklinAll8735 Your lecture about viral vector vaccines not qualifying as "traditional" (they already have been used against Ebola and do basically the same as traditional live attenuated vaccines) can't distract from the fact that neither viral vectors vaccines nor mRNA vaccines are a form of gene therapy, which is your actual message. If they don't change the cell's DNA, then it clearly does not have the same effect and is not a gene therapy by definition. In the real world, words have meaning and do not turn into the opposite because Facebook University told you so. Of course, when your predictions about "dire consequences" inevitably never come true, you won't stop blindly believing any nonsense that feeds into your paranoid schizophrenic fears of the evil government, but I'm not here to cure your mental illness, I'm just correcting misinformation that tries to escape the echo chambers of lunacy on the internet.
Adenovirus vectors are the most commonly employed vector for cancer gene therapy. They are also used for gene therapy and as vaccines to express foreign antigens. Adenovirus vectors can be replication-defective; certain essential viral genes are deleted and replaced by a cassette that expresses a foreign therapeutic gene. Such vectors are used for gene therapy, as vaccines, and for cancer therapy. Don't talk about things you have no knowledge. Adenoviruses used as viral vectors are gene therapy. They transport certain genes to the host cell to achieve therapeutical effect which is a very definition of gene therapy. No need to alter DNA.
The potential is staggering. When I was in 8th grade (1964) we vaguely understood what DNA and RNA were. In the interim we learned how they do what they do, and now we have technology with potential almost beyond imagination. We can potentially engineer therapeutics that not only target viruses, but bacteria, prions, and even cancer cells and organic toxins. What a time to be alive!
Let me give an example. A computer game. There is no game that is pefect and bugless at the day of the launch, for many months/years they receive updates to fix things that developers had no idea could cause bugs and only after community insight they are able to fix them. It is the same principle with gene therapies aka covid vaccines. Scientists programmed the mRNA to make our cells produce spike proteins but they have no idea of other things that could go very wrong and there is a great likelihood they will, so called Murphy's law. Few months of few tens of thousands people are not enough to ensure safety, it will take decades as a matter of fact. People who take this gene therapy aka vaccine will be the gamers playing alpha build of the game and they will give scientists the needed insight but if things go wrong it will not be your game character getting stuck in the wall but you dying.

You guys need to tone down the jump cuts a notch or two.

Seriously, is it that difficult to record a multi-sentence paragraph in one take? Rose has potential, but this rushed style doesn't suit her, a slightly slower pace and lower voice would probably work better.
This editing style works better for "long flowy" presenters like Hank. Rose has a bit of a staccato to her style so the editing makes it WAY more pronounced.
I agree. I think it is because the presenters see themselves needing to project loudly to a distant listener. They should try to imagine they are talking to someone literally 2 feet away, so they have a softer tone and more natural lilt.
Being vaccinated and recovering from COVID-19 create the same kind of immunity. The reason the vaccine is preferable is that it comes without the side effects of getting COVID, which can be devastating neurological problems. It's called PCS, or Post-COVID Syndrome. Edit: I forgot this reason- it's also because the vaccines can create a wider range of immunity. They can defend against the more aggressive variants more easily than the body's natural antibodies.
What happens when these antigens spikes cross the blood brain barrier and insert themselves into protein receptors in the brain? The CDC said they don't flush out of the brain. Just a question if we are allowed to ask anymore.
What makes you think that they'll pass the blood brain barrier? I haven't seen anything on that and I sleep an eye on updates about the virus and the vaccine.
@ so that a big article, I did check a couple of their links, one was study about the presence of S2 and other things related to the vaccine in blood serum. The article portrays it as something ominous, but upon reading the actual linked paper I found that the author's didn't have anything like that in their paper. Also, that site has a strong bias, do you perhaps have something s little more academic as a source?
Congrats. Got my second shot on 1/12 (hospital staff). Very minor side effects from the second shot (slight fever, lasted about 12 hours), and have otherwise had no issues.
I'm concerned about the information at 3:46 in the video. Could we delve deeper into how/why/for how long "our cells display the spikes (which they coded from the mRNA) on their surfaces"?
Not the actual spikes are portrayed. Rather small parts of it that the cell cuts from the large one. The fragments are portrayed on MHCI molecules, which then alert the immune system. Every cell always presents pieces of proteins from inside the cytosol (inside of the cell) on MHCI to passing immune cells. You can think of it as a ID check. If the immune system recognizes foreign proteins, such as a viral spike protein, then an immune response is activated.
"The immune system spots them and starts taking action". In other words, our immune systems kills the foreign proteins and by doing so, learns how to fight that specific foreign body. Viruses work by injecting their own mRNA into our cells and make our cells produce more of the virus. The difference between the virus mRNA and the vaccine mRNA is that the virus mRNA has info for our cells to pump out entire new virus cells while the vaccine mRNA only has info for creating the antigens. So if COVID-19 virus were to get into the body then the body would recognize the foreign antigens on the virus and kill the whole virus.
Yeah, that caught my attention. I assumed cells were being programed to create the spikes and releasing them outside the cell and immune system found them. But it sounded like it's causing mutations to certain cells and our body is attacking those cells. This is only temporary for a cell? or perhaps not and they are sacrificed for the cause? Or those cells aren't killed, but the immune system IDs the spikes as foreign? Muscle cells do regenerate quickly and maybe that's the reason they are injected in the arm muscle- some cells are sacrificed
@@RyanPurcell not mutations, no. That would imply that the actual DNA for the cell is being altered, and it's not. This is more like assigning your cells a task to temporarily make this particular protein. The non-nucleic structures in your cells are used to getting these tasks from the nucleus, delivered using mRNA. But the vaccine doesn't have to alter the DNA in the nucleus to send this message, it just needs to deliver the mRNA into cells so the instructions can be read. Kinda like how not every bit of software you install on your computer completely rewrites the operating system - the computer can still carry out assigned programs without having its core instruction manual altered. As for whether some of your cells will be attacked and killed... maybe? I don't pretend to have expertise on this, but I do know that cytotoxic t cells and natural killer cells both target and destroy cells that appear to have been compromised by a virus. The cytotoxic t cells scan cells for proteins they know to be foreign, while the natural killer cells target any cells that are (for lack of a more detailed explanation) behaving suspiciously. Viruses make themselves vulnerable to t cells by allowing their foreign proteins to be displayed on the outside of the cell, but if they try to be sneaky by forcing the hijacked cell to no longer display proteins then the natural killer cells will target the "suspicious" cell that isn't properly displaying proteins. So it seems likely that some of your cells which end up making the foreign spike protein will be targeted by the immune system. However, that's also how and why the vaccine works, and the lost cells will probably hardly be noticed by the body. Defective cells are killed by your immune system every day, and unlike a real virus the vaccine mRNA will not grow exponentially to infect new cells in your body (forcing the immune system to kill more and more of your own cells).

I have seen many scishow videos on the covid vaccines before, but there is something here I don't think I have seen before. Did she say the proteins mount on our cells? So the entire cell gets destroyed?
Why did they coincidentally work out of nowhere in time for this pandemic and not before? At what point did we know that they would work? And if we knew before covid-19 came along how come we didn't use it for other diseases?
How about doing another video about the harmful effects of the mRNA vaccine. I personally know several people who experienced severe side effects after the booster jabs.
No. The risks that come with the shot are above all thigs low and quite rare. Besides, the benefits of taking it surpass every single risk. Those who didn't take it are way more susceptible to a worse risk: death itself. If you're still skeptical about it, try spending some time in Pubmed or in the NCBI library. I'm sure you'll probably change your mind and accept your ignorance. Plus, you cannot diagnose or make a direct link between one's symptoms and the vaccine. You are not a medical professional. And probably not even educated academically. So you should not talk about what you don't know.
I don't know anyone who has died from the vaccines. I actually know someone who is immunocompromised and they took both the Pfizer and Moderna shots with NO effect. You would think they'd be the most likely ones to suffer something but nope.

Spike proteins are the "key" that fits into the cells "locks" those individuals who you state allegedly died from arrhythmias induced by cardiac inflammation would have had those "locks" present on those cells. And the affinity for the spike proteins "keys" to fit in them, thus triggering an over compensating immune response. That's assuming everything in your previous statement is accurate, it's entirely possible, even with inflammation present over the cardiacs nervous system, someone would live an otherwise healthy life
@@nephron9924 When they give u the covid shot they assume it will stay in the injected muscle. What it they hit an artery and inject it into your bloodstream.
Yes, cells that produce the spike protein are deemed death worthy by the immune system, as if they were infected. Infected cells are forced by a virus to produce new viruses, but every cell presents parts of what it produces on its outside. The immune system constantly checks if the products are normal or weird. Cells that produce weird stuff will be killed. That is also true for cancer cells. So, mRNA will probably be used to cure cancer in the near future.
Can someone explain how many of our cells start making these antigens? If our own cells are presenting the antigen, and then our body attacks those cells, that sounds like an autoimmune disease to me. Is there some way they are able to limit the number of cells presenting the antigen?

@@Vikingarmrestling Sometime getting in contact with it once is not enough. You need two times. This is why most vaccines of Covid is two doses. You catching it is pretty much like having one dose. You still need a dose if you want maximum protection. And this is not just to protect you... this is also to protect other people around you.
@@Vikingarmrestling That doesn't mean you will be that lucky the second time. A huge part of the symptoms are actually done by your own body.

If you get it again you may infect other people... and IF you still get symptoms, this is even worst as you will spread it without knowing it.
So if the mRNA instructions cause our cells to create and display the spikes on their cells ( 3:46 ) then does our immune system attack and destroy those particular human cells that are producing the spikes? Or do the spikes fall off or otherwise float freely through our blood after being displayed, to be detected elsewhere?
The immune system will kill that cell. But the mRNA or the vaccine is so little that it only affect a small portion of your arm cell. Plus, they won't float in your system because they are so fragile and can be destroyed easily. Which is why you need second vaccine. A small portion of cell to protect you from a massive cell death when you get covid. Plus you lose millions of cell every minute so it's not something you should worry about.
The immune system attacks the proteins, not the cell. As the proteins are sitting on the outside of the cell, and aren’t needed for the cell’s functioning, when the immune response destroys the protein, whether or not the cell displaying the protein is destroyed or not depends on the type of white cell that attacks the protein. Some will just denature the protein, leaving the cell intact, others will break down the entire cell. Neither is cause for alarm - our immune system destroy cells all the time - millions every day, as those cells get old and are replaced by new ones.

People get sick after the shot because they are having an immune response. Your body heats up because viruses don’t reproduce as well at higher temperatures. Basically your body puts a bunch of energy towards removing the foreign substance, which can make you feel sick, but the substance itself isn’t making you sick. I don’t why the blood clots happen but they happened after the J&j shot which is not an mRNA vaccine. They were also rare relative to the number of people who got the j&j.
People are getting sick after the shot because of the body's natural immune response, and people are getting blood clots for the same reasons they always have. But something tells me you knew that already
As noted by others. Whenever your immune system reacts to something the resulting symptomatology reflects the areas of the body impacted. In other words if you catch say the Flu to develop mostly respiratory symptoms that is because the Influenza virus can infect those cells in the body to cause an inflammatory/immune reaction. So the SARS-CoV-2 virus antigens - your "protein spikes" - have a high affinity for ACE2 receptors found in the body. Those receptors however are ubiquitous being found on cells everywhere in the body - especially your cardiac/vascular tissues. This means the virus itself and the resulting protein spikes created by the mRNA vaccine can attach to cells throughout the body to trigger an inflammatory reaction. So your body raises its temperature - read an inflammatory reaction - which may or may not defeat infectious pathogens which can only survive in a given temperature range. You feel "achy" because more blood is being shunted to your muscles/extremities - vascular dilation - which helps immune cells get to where they are needed. More blood in your extremities means less for your core system like your brain - hence headaches and so on. These are all "uncomfortable" - albeit necessary - side effects of an immune reaction. p.s. - people hospitalized with actual Covid also develop blood clots as well = in far greater numbers than the rare cases seen with certain vaccines. Clots are a reaction to = inflammation - which as noted above the Covid virus can cause on a systemic level given its ability to impact cells throughout the body.
Not really, it was doctor Robert Malone. She figured out how to get it into the body. "In 1961, the biologists Sydney Brenner, Francois Jacob and Matthew Meselson discovered that RNA transported genetic information. They also found that the process could be used to produce proteins in cells. But it wasn't until 1989 that virologist Robert Malone managed to demonstrate the process. Researchers carried out the first laboratory studies with mRNA vaccines on mice in 1993 and 1994."
No one has been able to answer the below. How long does the 'spike protein' created by these vaccines stay in your body ? Does the 'Spike Protein' enter the brain and other organs in the body ?
The spike protein is produced in cells around the vaccine injection point. I think it goes into the blood from the muscle it is injected into, but mostly stays in the muscle tissue. Hence why people have a sore arm after the shot. The soreness shows the body is attacking the cells that produce the spike protein. The cells that have the spike protein are killed and removed. I believe the blood brain barrier stops any of the vaccine going into the brain.
@@patientestant Yep, also the vaccine is localised only. It doesn't travel around the body, and it ideally doesn't enter circulation, only enters the lymphatic system where out immune cells live.
@@DocLarsen44 says the person who flunked highschool Biology, before failing his GED test. Meanwhile, those of us with solid backgrounds in the Sciences know better. #ByeFelicia.
Honestly, even if the mRNA got into the nucleus, it wouldn't cause any issues. Humans don't innately have any machinery to translate RNA back to DNA, so there's no genetic modification going on. And even if we did somehow make DNA copies of the vaccine's mRNA (reverse transcription is the term), the chances of it actually integrating into the cell's genome is EXTREMELY small*. *This is due to a host of reasons, but a big one being that our cells actually contain a large number of enzymes designed to break down foreign DNA and RNA, as well as recycling our own cells' molecules. This means that free-floating DNA and RNA generally don't last particularly long--which has been a great evolved mechanism against viruses.
I don't know why I had to get so far down in the comments before someone stated this. mRNA really is a 1-way path in protein fabrication; it's essentially a Xeroxed copy of the blueprints (DNA) for the protein; a copy that is meant to be shredded right after use.
Why can't we just produce the antigens in a lab and inject that directly? Is there no generic cell that we can use to produce antigens outside of the human body? Why do we have to make our own cells produce the antigens?
Fewer rejection reactions with straight mRNA. 20th century vaccines are quite 'dirty" that way; I have a family member who has not been able to take flu vaccines until recently because they were cultured in egg.
Right, why not just do the tested and old faithful that’s working for hundreds of years. Why tamper with our mRNA. Then mandate people to try a product we are still studying?
The vaccine is benign. It's possible it may not work or work long term but it should not have any serious long term consequences for most people. Yes we are playing a game and making the rules up as we go along but if we do nothing then we will never contain the virus.
@@donnash5813 with some mortality rate as low as it is and the demographics of the people who have the highest susceptibility to have symptoms and die and all the very effective treatments that have been developed I don't think it is necessary that the vaccine be mandatory or be required for travel or work or school.
@@despaahana I don't think it should be mandatory for everyone either. The vaccine was rushed and we are all a big experiment. My point is the vaccine is benign for most people. The J&J vaccine seems to cause blood clots in some people which is why it was pulled from the market for a while. The drug companies and health organizations will be keeping track of how well the vaccines worked for years into the future. I just feel the vaccine is our best chance to beat the virus especially as it is mutating.
Why would there be a difference in time that a memory cells sticks around or is able to remember to provide protection from an antigen that is created from an mRNA vaccine vs more traditional vaccines? Not sure if I used the right terms, but I'm curious about how you can determine how long a person will be protected and how that differs with the mRNA vaccines.
generally your memeory cells can last decades though they do dwindle in number if you don't get reinfected for a long time. The real concern is if the virus's proteins end up changing in such a way that still lets them infect you but doesn't let you recognize them. The only difference in duration you could see would come from dosage. how big of a reaction does this vaccine elicit compared to a normal one. that kinda thing.
It differs between vaccines, between different illnesses and between different people. These values are subsequently determined statistically. It is too early now to tell, maybe there will be an annual vaccination like for the common flu.
I don’t think there is a difference in how long the protection would last. The protection only wanes as the virus out in the world mutates such that the memory cells no longer recognize it.
How long vaccine provides protection is very complicated so they don't actually know how long it will last. I think some covid vaccines (not in the USA) are not mRNA based, so we will likely be able to at least get a rough idea if the longevity is similar or not.
@@ttrev007 yup! the first batch to come out used another new tech that synthesized the spike protines en mass using modified microbes to mass produce em. then we got the mrna ones so we have both now
The thera gripper they implanted you with probably won't hurt you unless it's activated by a 5G signal. (I'm kidding but at the same time it wouldn't surprise if it turned out to be true)
@@sameppink9401 Thats not true. Moderna and Pfizer have blood clots too, about 4 in million with the adenovirus vaccines being 5 in one million. Look up the Oxford study on it, can't post the link it will be taken down.
To elaborate on Sam's (correct) point, they're different vaccines, they're under review (so we don't know the cause yet) and the rate was literally less than 1 in a million so that'd still be an acceptable risk if we didn't have alternatives.
the spike protein is what allows covid virus to attach itself to cells. if mRNA goes inside blood cells the blood cells will produce the spike protein and with other nearby blood cells they will get clump together causing a blood clot just hope mRNA doesn't enter blood cells
Oh, so it didn't take a whole year to roll out a brand new type of vaccine under an executive order called "warp speed", and all of last year totally didn't happen.
@@akabga we already had mRNA vaccines. We've already been running mRNA trials for other diseases. We've been doing it since SARS-CoV-1 (2003-2004). The approval has just been sitting in the government offices until COVID came along. It only took a year because they had to re-do whatever they did but for SARS-CoV-2 instead.
@@PixlRainbow Like, there weren't other, quicker, more viable methods that have hundreds of years of documented success. Nope. We had to "re-do", such as "reinvent", like a wheel, or something along those lines. 🤔 Like I was saying.
@@akabga the hundred year old methods would have taken more than a whole year. We would have to re-do everything with those too. SARS-CoV-2 is a new virus after all.
Kinda missed how the mrna get transfered from the syringe to the desired cell... Does it get introduced into all types of cells (or most) and they display the spike proteins or only immune cells can display them? If the mrna transported via exosome, how do we prevent it from fusing to any or all cells? Finally I've been watching this channel for many years and I don't know if it's me or this presenter in particular but I've noticed that more than explaining a concept it seems much more like it's being read. I know it IS being red, but I've been noticing the explanation "too much" as if they're reading them. Anyways keep it up as always!
The mRNA is encased in a lipid membrane. JUST LIKE ALL of your cells are. This membrane will fuse with some cell membranes and deliver the mRNA into them, which then are picked up by the ribosomes etc. etc. etc.
@@ModernWelfareThree These nanoparticles will fuse with all cells they contact. Mostly with the cells presented in muscle tissue, however the nanoparticles may also go to a bloodstream and potentially can transfect any type of cells. I don't know if these nanoparticles can cross the Brain-Blood barrier or Placenta-Blood barrier.
I really hope Katalin Karikó and Drew Weissman get a Nobel Prize for their work to make mRNA vaccines viable. There's a great article in Stat titled "The story of MRNA: From a loose idea to a tool that may help curb Covid" about the history of its development.
It would be really cool to have another woman win the nobel prize! Not because women should get nobel prizes, just for being women, obviously, before anyone understands me wrong, but it's just cool when a woman has participated in important research and it's recognised, so people see that women can do great things as well, so more girls are inspired to go into science! Especially when it's about such an important topic like the way to end the pandemic. I'm a woman wanting to go into science (I'm in my 4th semester at uni), and my role models were my dad (who has a PhD in physics, but doesn't work in science anymore, and who encouraged me to pursue science) and Irene Pepperberg. Katalin Karikó could be a role model for many more girls to come, so it would be really neat if she got the nobel prize!
@@solar0wind Wholly agreed. Especially considering how many women did nobel-worthy work only to have their male colleagues receive the prize. Women like Jocelyn Bell Burnell, Chien-Shiung Wu, and Lise Meitner come to mind but there are certainly others. Personally I see it as a great shame that academia was a "no girls allowed" club for so long. It's disappointing to think of how much more we could have learned by now if not for excluding half of the population from the means to discover and share their discoveries. Though, while I agree representation matters. It seems now an additional issue is some men in academia doing their darndest to make women feel unwelcome. It doesn't help to drive women into science if when they get there they want to leave before long. I hope those doing this are merely a vocal minority. We've made progress but there is still more to do. I wish you all the best in your academic journey and I hope you'll remember that you belong there just as much as anyone else. Anyone that tries to make you feel unwelcome is merely expressing their insecurities. Also I knew of Alex the grey parrot but not Irene Pepperberg so it seems I have some reading to do. Cheers to your father for being a great role model :]
@ the 4 min 55 second mark you mention that past MRNA vaccines never made it out of clinical trials. You also say that in the past “they were unable to get them to work properly, but these two new vaccines do work.” How specifically do we know they work? Especially since their was almost no time to test them? Asking for a friend.
The reason we know they do work is because of the same large scale case studies that get performed with any other vaccine in trial, where a large number of people are monitored for two things: -Delta of Rate of infection -Delta of higher severity cases Delta describes the difference in cases compared to a non-vaccinated control group of the same size, tracked over a set amount of time. I.E., if you see Biontech's "90-95% secure", that means that these studies have shown a total of 90-95% less infection and/or severe case developments compared to the non-vaccinated group. Again, note that these studies are the same performed for every single vaccine out there. They do not differ due to the vaccine type.

Why people having horrible reactions some life threatening and some dying shortly after?! Now I've seen and heard about shedding to people that haven't got it
Because this wasnt fully explained in this vid. The mrna coding actually uses YOUR ribosome. In this vid, they said "a." Sounds trivial, but to an unsuspecting person, they wouldnt know how important language is. It sets off the red flags when you need to know something is amiss. So, the coding (so they say!) is for a viral spike protein & then it uses YOUR ribosome & YOUR trna delivers amino acid. All that together grows a spike protein that is part viral & part you. After that, you make antibodies against not just the viral spike, but the combination of spike & yourself. Basically, the ones who get this are the ones that need to make sure that they dont get sick with something that has that spike in the future because it will go for more than just that spike. As for the terrible reations, since your body NORMALLY destroys foreign mRNA, they had to hide it in a fat pock called polyethyleneglycol (PEG) to bypass your body's defenses & get to your ribosome. Some people will absolutely have anaphalctic reaction to PEG that can be deadly. The other possibilities are: 1) your body was never meant to make proteins that are not for itself so as the entire body tries this, its too much 2) not all vials contain the same dosing 3) not all vials contain the same coding? Is it possible experimentation on how to turn on & off genes to have certain things happen is also being experimented with? Perhaps. I mean we saw at the beginning, tremmors & bells palsy, then later a huge amount of eye disorders in the UK, now, we are hearing of fully body rashes & blood clots. Its just a little weird how these reactions have "groupings" of types. 4) its possible they came into contact with a naturally occuring RonaV shortly after their body started producing antibodies & (remember they are trained for part v, part you) now they have an autoimmune/self attacking response, instead of a more natural, "just going after the v" response like normal vac technology is supposed to train your body to produce. ... also, viral shedding is a thing, so since a person GROWS the viral protein when they get this, shedding eventually occurs.

@@Bryan-Hensley It’s good when scientists admit that they’re not 100% sure of something, it means honesty. Heck, even a 99.7% safety guarantee still means a small chance of something going wrong, doesn’t mean the costs outweigh the benefit, they don’t. Stop instilling fear in people, to hell with your misinformation.
Just got vaccinated and the fact that it was rushed and that it was a first time thing was really creeping me out the more I thought about it. I’m no virologist or geneticists, so I knew my fears could be baseless(that also means I don’t fully know how to feel about this video), but this vid eased my fears a bit.
mRNA vaccines have been used in veterinary practice for a while now, this is really just the first use on humans, but even so they should be safer than traditional vaccines. also the rush was more about skipping most of the red tape rather than actual safety procedures
@@paleoleft I'm not fear mongering I'm fearful for my fellow people. We learned what mRNA is middle school. We don't need it fight a virus that kills less than 1%
This is a good video, but can you describe the process of cross presentation of the antigen (transcribed from the mRNA) in dendritic cells which is how we elicit the immune response and subsequent T/B cell memory in first place?
wait is it making antigens or the spike protein that then the body reacts to and makes antigens and then white blood cells recognize it. Also make it sound as if the spike proteins come out of the cell that reads the instructions and makes them so then the immune system destroys those cells? how does the mRNA get into the cells and which ones? Also I understand it wont edit our dna but can another virus integrate this into their dna say you are already sick with something that could use this and when it reproduces it has those instructions now. cuz isnt the spikes what made sars-cov-2 so contagious?
1. so then the immune system destroys those cells? Yes 2. how does the mRNA get into the cells and which ones? the cells are random. It's whatever the mRNA bumps into first. It will usually be a muscle cell since they are injecting into your upper arm muscle though. The mRNA is wrapped in a bubble of oil, and your cells outer membranes are also made of oil, so the bubble dissolves into the membrane and the mRNA gets dumped into the cell along with it. 3. can another virus integrate this into their dna RNA is chemically a different molecule from DNA. You can't join them together.
The nano lipid layer around the mRNA is attracted to any and all plasma membranes, which means technically it'll fuse with any cell with a membrane. Which is all cells. Because of this the chosen injection site is the deltoid muscle. It is so densely packed with muscle cells, injecting into the blood stream directly is highly unlikely. So the main cells affected are the muscle cells as well as dendritic cells (APCs). The dendritic cells would be chilling in the lymph nodes which the vaccine can reach via lymphatic circulation (different from blood circulation) thats easily accessible from arm, cuz we got a lymph nodes in our armpits.

I would get it again before taking an experimental "vaccine" that its research data is still not been completely released. But hey, that's just me, do what you like.
How does the mRNA control for how much spike protein is produced? And when there is enough of it in the system, what signals it to be shut off (to not produce anymore spike protein)?
There is no control. The pseudouridnated mRNA hangs around for months in the body in places like ovaries, heart, etc. and the amount of poisonous and inflammatory spike protein it produces is highly variable so the injectee is essentially getting an uncontrolled dose of a very harmful protein. What could possibly go wrong? ;)
Do our cells really "display the finished spikes on the [the cell's] surface"? I was under the impression that the spikes get broken down into antigens that somehow make it out of the cell to get attacked (I'm not sure exactly what happens tbh). One of my friends suffered through an auto-immune disease a few years back, and currently refuses to get vaccinated because he believes that, like in the visual part of the video at 3:49, the immune system is attacking our own cells with the spike protein somehow expressed on the surface (Auto-immune fear of some kind). Idk if he got his information from scishow, but maybe there is more proliferation of this kind of misconception (?) causing a bit of fear for those with auto-immune diseases.
It is nothing more than the protein that is created and it is the same protein that the spikes are made out of on the covid virus. When that virus enters into your system it already knows what to do because it's the same protein.
Both, it depends on what cell the mRNA enters. If it enters a type of cell called a dendritic cell, then it would be processed and presented on a MHC molecule so other immune cells can see and recognise it. If it enters another immune cell, it'll induce production of the spike protein to it's surface, to which other immune cells can recognise it and mount an attack on the cell. So our own cells that express the spike protein do die, but its a very limited amount (limited by vaccine dose), because there is no virus replication going on, so what we are injected with is what we get. Yes our cells are attacked, but a comparatively small amount. Autoimmunity happens when a self-reactive cell escapes into our circulation and attacks our own cells. Everyone has self-reactive cells, normally they are cleared away through several selection processes.
Something not explained is-what is the protein made by the cell ribosome that is coded by the mRNA from the virus. Is it a protein the cell normally uses but just a piece put in by the mRNA code. Or does the mRNA create an actual protein specific to that mRNA in the vaccine.
This is a good basic video, but I'm really interested in the two topics you hinted at here: 4:37 -- Researchers had to figure out how to make the RNA molecules last long enough in our bodies to actually get translated (into the spike protein) -- how did they do this? Why did it take so long? How were they able to make it happen so fast once the pandemic struck? 4:46 -- They had to work out the perfect delivery vehicle to get the mRNA into cells, and minimize side effects -- these were the famous lipid nanoparticles -- more on this? Inquiring minds want to know.
 On Tuesday, June 28, FDA’s VRBPAC committee will meet to discuss and vote on a “Future Framework” for evaluating the “next generation” COVID-19 shots. If approved, this allows vaccine manufacturers to bypass the regulatory process and skip clinical trials of newly reformulated COVID shots, in perpetuity.
The nano lipid layer surrounding the mRNA is attracted to any cell membrane, this is why the chosen injection site is our deltoid muscle, because its densely packed with muscle cells which means the injection is unlikely to be delivered directly into our blood stream. Due to this, the main cells that mRNA will enter are muscle cells but also dendritic cells (APC). The vaccine can enter our lymphatic system to go to our lymph nodes where most of our important adaptive immune cells (dendritic cells) chill in.
I love how they stated it is safe and effective too. All while saying how not a single mRNA vaccine has ever made it through trials (What they didn't state: because they all failed long-term studies). SciShow didn't even hint at any concern. Stated it is safe despite all mRNA vaccine history showing it is not safe. They didn't even say for pregnant or breastfeeding women to be cautious.. Getting pregnant/breastfeeding women involved in a clinical trial deserves criminal charges.
Several channels here on YT have already made similar vids months ago. All of this basic stuff has been given out to the "public" for some time already. Problem is, most people don't try to learn anything, they wait to be spoon-fed! Stay well.
Many people here worries about AD, (auto immunity disease) after artificial vaccine shot. If people have immature innate immunity, there this chance increases. That's why the most side effects are mainly occuring within young women. They usually does not much live outworld life and has also short time or history to contact innate immunity or pathogen. Above chance are more risky when they get cought with real virus, but vaccine has no big risk because the mRNA injection amounts are small and it has no power to cell life mutation. But eventhough our body immune cell mechanisms are so complicated. So there is no gurantee and they have to be careful. The only way to overcome above matters are everybody train self innate immunity everyday before things happen in their body.
What a simplistic information about the vaccines. It is like teaching at kids at the pre-school level. I think it should be a little more elaborated. And answer some questions: what is the carrier that take the mRNA to the Ribosomes? If they do not integrate to our genomes, how are we going to guarantee that they will maintain the production of the spike proteins long enough to give us immunity? What are the negative effects of those spike proteins?
Thank you, it's explaining what they are and what they do in a simple and short way. I'm getting my shot (mRNA) in a couple of days and I'm a little nervous.
i got mine and it sucks symptom wise so make sure you can take time off for a few days when needed. :)) unless you have an allergic reaction you’re fine
Just be glad that you won't get AstraZeneca😂 It's a good vaccine, but the side effects feel like a bad cold. My boyfriend got the first shot last month and suffered a lot for two days, so it was quite unpleasant, but now younger people aren't supposed to get this vaccine anymore here because of a one in a million people side effect basically, so it's unclear what vaccine he's gonna get for his second shot.
The fact is, the manufactured pathogenic spike protein units are NOT displayed on the muscle cell. Instead, as the pathogenic spike protein units are manufactured within the cell, the cell swells and then bursts, releasing the pathogenic spike units. Hint: Look up "endotheliitis"

Covid doesn't penetrate our skin, yes. Our outsides are secure. BUT our INSIDES are not. Think of the skin as a shield...whats on the other end of it - the fragile human that can't take a sword to his chest. Covid gets inside our bodies through inhaling droplets that carry it. People sneezing or breathing creates those droplets. The more droplets from someone infected, and the further he is down the infection path, the higher number of covid cells do we inhale. New covid mutations currently are waaaaaaay more infectious. The virus can replicate faster and in turn drop you faster. And to top it all off...it acts like a hidden time bomb. You don't notice it until one day you can't fully breathe. The fun part starts here - covid can travel to the kidneys, liver, lungs, brain, gut. If your blood is thick and you begin treatment, said treatment includes antibiotics which dilute your blood. Any trombs that were stuck to your vein walls are now floating about, and will 100% create heart failure. Aspirin protect helps with keeping your blood diluted. Blood highways should not have solid particles in them like trombs or cholesterol buildup.

How does it get to liver, kidneys - after traveling to the gut and moving onward for nutrient processing, those two create blood pressure chemicals from stress or some other ailment. Covid can attach itself to the types of cells that create the cortisol (i think thats what the blood pressure biochemical we produce is called). Keeping normal blood pressure is also beneficial.
Furthermore, people have all sorts of illnesses they don't feel or know about. Covid can and WILL trigger something else if you catch it. Athletes have caught it. 20-30 y/o have had it. Some have survived and some sadly haven't.
Another important thing. Kids have low percent chance of getting hit bt covid, but the cruicial part everyone seems to forget constantly is that they can transmit it to their parents and teachers. Covid can live ontop copper for a day. It can live on porous surfaces for up to 72 hours and more in some cases. You think an oily teenager skin isn't the perfect surface for covid to live on? He then touches everything his parents touch. Reported PROVEN cases plethora are out there of this exact thing happening. Yet the mass overlooks it because its simply tired.

@@Theo0x89 Before trying to lecture someone do some research because now you look silly. Traditional method would be to inject weakened, inactivated or part of the covid virus so that the body could recognize the virus and develop natural immunity. None of the 'vaccines' I mentioned do that. They all deliver a set of instruction to the host cell and the very host produces the coronavirus spike protein. The difference between pfizer/moderna and astrazeneca/JJ is only the delivery vehicle. Former use nanoparticles to enter the cell and deliver instructions(mRNA) while the latter use a modified chimpanzee adenovirus to infiltrate the cell and injects its DNA into the nucleus. That is a gene therapy. It does not change dna pressumably (which is theoretically possible with adenovirus vectors) but the effect is exactly the same. Your body is instructed to produce whatever foreign proteins are encoded on the mRNA / viral DNA. You sir, are an ignorant sheep, an exemplary soviet citizen, who would inject whatever the big daddy governments wants you to and you will very likely pay dire consequences of your choices in the future.
@@franklinAll8735 Your lecture about viral vector vaccines not qualifying as "traditional" (they already have been used against Ebola and do basically the same as traditional live attenuated vaccines) can't distract from the fact that neither viral vectors vaccines nor mRNA vaccines are a form of gene therapy, which is your actual message. If they don't change the cell's DNA, then it clearly does not have the same effect and is not a gene therapy by definition. In the real world, words have meaning and do not turn into the opposite because Facebook University told you so. Of course, when your predictions about "dire consequences" inevitably never come true, you won't stop blindly believing any nonsense that feeds into your paranoid schizophrenic fears of the evil government, but I'm not here to cure your mental illness, I'm just correcting misinformation that tries to escape the echo chambers of lunacy on the internet.
Adenovirus vectors are the most commonly employed vector for cancer gene therapy. They are also used for gene therapy and as vaccines to express foreign antigens. Adenovirus vectors can be replication-defective; certain essential viral genes are deleted and replaced by a cassette that expresses a foreign therapeutic gene. Such vectors are used for gene therapy, as vaccines, and for cancer therapy.
Don't talk about things you have no knowledge. Adenoviruses used as viral vectors are gene therapy. They transport certain genes to the host cell to achieve therapeutical effect which is a very definition of gene therapy. No need to alter DNA.
They do work.....at least to the best of our knowledge.....so far. Doesn't exactly fill me with confidence.
It’s pretty cool that we’ve (our conscious brains) figured out how to talk to our body/cells
Metalanguage.
The potential is staggering. When I was in 8th grade (1964) we vaguely understood what DNA and RNA were. In the interim we learned how they do what they do, and now we have technology with potential almost beyond imagination. We can potentially engineer therapeutics that not only target viruses, but bacteria, prions, and even cancer cells and organic toxins. What a time to be alive!

Which cells in your body are creating these new proteins? Because I have been unable to find that answer. Are they blood, liver, kidney, brain, bone, etc cells or a combination of various cells?
@@randomslacker9204 all cells have ribosomes . Hence all cells are capable of making proteins
@@JohnDoe19991 I understand that all cells are capable of making proteins. Which is how brain cells keep healthy although they do not replace themselves. But for the terms of my original question is which cells are being instructed to make this new protein. That being whichever cells decide to pretend to be the virus will ultimately be destroyed by your immune system.
@@randomslacker9204 any cell that receives the mRNA will start making the antigen . Which will move into the blood stream and be detected by immune cells which will trigger an immune response to create the antibody and memory cells will cache it for quicker response during the next attack . So no no cell is acting as the virus they just produce the spike proteins of virus that will trigger immune response

LOVING that my favorite presenter (Rose[Bear Don't Walk]) is showing up a lot more frequently.

You guys need to tone down the jump cuts a notch or two. At least leave a pause between the sentences, the last word is barely over before the whole thing jumps to another sentence from a different take. Seriously, is it that difficult to record a multi-sentence paragraph in one take?
Rose has potential, but this rushed style doesn't suit her, a slightly slower pace and lower voice would probably work better.
This editing style works better for "long flowy" presenters like Hank. Rose has a bit of a staccato to her style so the editing makes it WAY more pronounced.
I agree. I think it is because the presenters see themselves needing to project loudly to a distant listener. They should try to imagine they are talking to someone literally 2 feet away, so they have a softer tone and more natural lilt.
Spoiler alert: she probably isn't smart enough to that.
I have a doubt..How is a vaccinated person more immune than a person who have contracted the disease once and recovered from it?
Being vaccinated and recovering from COVID-19 create the same kind of immunity. The reason the vaccine is preferable is that it comes without the side effects of getting COVID, which can be devastating neurological problems. It's called PCS, or Post-COVID Syndrome.
Edit: I forgot this reason- it's also because the vaccines can create a wider range of immunity. They can defend against the more aggressive variants more easily than the body's natural antibodies.
@@SpringStarFangirl oh okay, thank you very much for sharing.

Haha that’s exactly what I said
No!....I am Legend ....is about curing cancer. Pay attention would ya!.
I'm concerned about the information at 3:46 in the video. Could we delve deeper into how/why/for how long "our cells display the spikes (which they coded from the mRNA) on their surfaces"?
Look up antigen processing. Antigens are broken up into epitopes and presented on MHC molecules for (other) immune cells to see.
Not the actual spikes are portrayed. Rather small parts of it that the cell cuts from the large one. The fragments are portrayed on MHCI molecules, which then alert the immune system. Every cell always presents pieces of proteins from inside the cytosol (inside of the cell) on MHCI to passing immune cells. You can think of it as a ID check. If the immune system recognizes foreign proteins, such as a viral spike protein, then an immune response is activated.
"The immune system spots them and starts taking action". In other words, our immune systems kills the foreign proteins and by doing so, learns how to fight that specific foreign body. Viruses work by injecting their own mRNA into our cells and make our cells produce more of the virus. The difference between the virus mRNA and the vaccine mRNA is that the virus mRNA has info for our cells to pump out entire new virus cells while the vaccine mRNA only has info for creating the antigens. So if COVID-19 virus were to get into the body then the body would recognize the foreign antigens on the virus and kill the whole virus.
Yeah, that caught my attention. I assumed cells were being programed to create the spikes and releasing them outside the cell and immune system found them. But it sounded like it's causing mutations to certain cells and our body is attacking those cells. This is only temporary for a cell? or perhaps not and they are sacrificed for the cause? Or those cells aren't killed, but the immune system IDs the spikes as foreign? Muscle cells do regenerate quickly and maybe that's the reason they are injected in the arm muscle- some cells are sacrificed
@@RyanPurcell not mutations, no. That would imply that the actual DNA for the cell is being altered, and it's not. This is more like assigning your cells a task to temporarily make this particular protein. The non-nucleic structures in your cells are used to getting these tasks from the nucleus, delivered using mRNA. But the vaccine doesn't have to alter the DNA in the nucleus to send this message, it just needs to deliver the mRNA into cells so the instructions can be read. Kinda like how not every bit of software you install on your computer completely rewrites the operating system - the computer can still carry out assigned programs without having its core instruction manual altered.
As for whether some of your cells will be attacked and killed... maybe? I don't pretend to have expertise on this, but I do know that cytotoxic t cells and natural killer cells both target and destroy cells that appear to have been compromised by a virus. The cytotoxic t cells scan cells for proteins they know to be foreign, while the natural killer cells target any cells that are (for lack of a more detailed explanation) behaving suspiciously. Viruses make themselves vulnerable to t cells by allowing their foreign proteins to be displayed on the outside of the cell, but if they try to be sneaky by forcing the hijacked cell to no longer display proteins then the natural killer cells will target the "suspicious" cell that isn't properly displaying proteins. So it seems likely that some of your cells which end up making the foreign spike protein will be targeted by the immune system. However, that's also how and why the vaccine works, and the lost cells will probably hardly be noticed by the body. Defective cells are killed by your immune system every day, and unlike a real virus the vaccine mRNA will not grow exponentially to infect new cells in your body (forcing the immune system to kill more and more of your own cells).

Such as?
I have seen many scishow videos on the covid vaccines before, but there is something here I don't think I have seen before. Did she say the proteins mount on our cells? So the entire cell gets destroyed?
I was surprised too. I thought those virus proteins just sorta floated there after being made until our immune systems found them.
yes they stick to some of out cells and are killed by our immune system helping it learn how to target the actual virus.
Why did they coincidentally work out of nowhere in time for this pandemic and not before? At what point did we know that they would work? And if we knew before covid-19 came along how come we didn't use it for other diseases?
How about doing another video about the harmful effects of the mRNA vaccine. I personally know several people who experienced severe side effects after the booster jabs.
Navmoc, i know several too. However, like the mainstream media, this doesn't strike me as the kind of channel that would want to rock the boat.
I have multiple coworkers with severe vaccine side effects. My management refused to report the injuries and hushed it up
No. The risks that come with the shot are above all thigs low and quite rare. Besides, the benefits of taking it surpass every single risk. Those who didn't take it are way more susceptible to a worse risk: death itself. If you're still skeptical about it, try spending some time in Pubmed or in the NCBI library. I'm sure you'll probably change your mind and accept your ignorance. Plus, you cannot diagnose or make a direct link between one's symptoms and the vaccine. You are not a medical professional. And probably not even educated academically. So you should not talk about what you don't know.
I don't know anyone who has died from the vaccines. I actually know someone who is immunocompromised and they took both the Pfizer and Moderna shots with NO effect. You would think they'd be the most likely ones to suffer something but nope.
So go get your vaccines people
Lipid (oil) bubbles

biopsies of people dying of an arrythmia show areas in the heart where spike proteins were attacked by the immune system that disrupted the hearts electrical system. How did the spike proteins or covid antigens get into the heart?
Spike proteins are the "key" that fits into the cells "locks" those individuals who you state allegedly died from arrhythmias induced by cardiac inflammation would have had those "locks" present on those cells. And the affinity for the spike proteins "keys" to fit in them, thus triggering an over compensating immune response.

@@nephron9924 When they give u the covid shot they assume it will stay in the injected muscle. What it they hit an artery and inject it into your bloodstream.
Does this mean that some of our own cells get destroyed by our immune system?
Bear in mind that (other than brain neurons) your cells are in a constant process of being destroyed and replaced anyway.
Wait till you see what the smallpox vaccine does to your skin, lol.
Yes, cells that produce the spike protein are deemed death worthy by the immune system, as if they were infected. Infected cells are forced by a virus to produce new viruses, but every cell presents parts of what it produces on its outside. The immune system constantly checks if the products are normal or weird. Cells that produce weird stuff will be killed. That is also true for cancer cells. So, mRNA will probably be used to cure cancer in the near future.
They do all the time. Getting rid of those dead cells is an important function of our lymphatic system.
Can someone explain how many of our cells start making these antigens? If our own cells are presenting the antigen, and then our body attacks those cells, that sounds like an autoimmune disease to me. Is there some way they are able to limit the number of cells presenting the antigen?
@@dackbowland1876 same here! Unfortunately I had to take a mRNA one to keep my job. It's been 6 months since my second dose and I get a weird feeling in my heart every once and awhile. So far, that is the only symptom that I have noticed, but course there is no way for me to truly know if the vaccine is causing that or something else. I still wish I could have gotten a traditional vaccine instead though.
So is this why some people have worst side effects from the second dose compared to the first dose? Their bodies create a strong immune response?
Yes. Those sides effect are mostly the body detecting the spike protein and attacking it right away.
Correct.
The second dose also introduces more mRNA than the first, so not only is the immune response already kicking in, but it ends up doing so on a larger scale.
So, can someone exlpain to me, why people still need me to show a vaccine pass to covid19, when i had the disease and survived it. Shouldnt my antigens already been made, and therefore i should be immune already,

So if the mRNA instructions cause our cells to create and display the spikes on their cells ( 3:46 ) then does our immune system attack and destroy those particular human cells that are producing the spikes? Or do the spikes fall off or otherwise float freely through our blood after being displayed, to be detected elsewhere?
The immune system will kill that cell. But the mRNA or the vaccine is so little that it only affect a small portion of your arm cell. Plus, they won't float in your system because they are so fragile and can be destroyed easily. Which is why you need second vaccine. A small portion of cell to protect you from a massive cell death when you get covid. Plus you lose millions of cell every minute so it's not something you should worry about.
@@sAnTinO8Bro yes and on top of this, the vaccine is floating in your blood so it won’t interact with important cells like nerve cells, :)
The immune system attacks the proteins, not the cell. As the proteins are sitting on the outside of the cell, and aren’t needed for the cell’s functioning, when the immune response destroys the protein, whether or not the cell displaying the protein is destroyed or not depends on the type of white cell that attacks the protein. Some will just denature the protein, leaving the cell intact, others will break down the entire cell. Neither is cause for alarm - our immune system destroy cells all the time - millions every day, as those cells get old and are replaced by new ones.
Every single cell that gets the mRNA in it either dies or is killed by your immune system. Every one of them!
@@coagulatedsalts4711 your nervous system is exempt from immune response. We don't have any immunity in our nervous system. That is why infection in the nervous system are so difficult to treat. Your nerve cells will be fine.
The vaccine misinformation in this comment section is so sad
But the question remains: How does it do all these things like entering cells and going to your ribosomes?
usually they’re delivered in viruses. scientists have identified the genes for making a virus’s shell and implant those into bacteria along with the mrna for replication, but the make sure that there are no genes that code for replication of the virus are included so that it never spreads/replicated in your body. so your cells get ‘infected’ with it but they don’t ‘infect’ other cells. i hope that makes sense. this is a standard process but i don’t know what they did for these
Very dangerous
@@maxmorris4562 If that sounds dangerous to you, you'd want to do your best not to get the real virus then. That one infests your DNA and makes the cell do nothing but make more virus.

Why are people so sick after the shot?? Also, why are some people getting blood clots?
People get sick after the shot because they are having an immune response. Your body heats up because viruses don’t reproduce as well at higher temperatures. Basically your body puts a bunch of energy towards removing the foreign substance, which can make you feel sick, but the substance itself isn’t making you sick.
I don’t why the blood clots happen but they happened after the J&j shot which is not an mRNA vaccine. They were also rare relative to the number of people who got the j&j.
People are getting sick after the shot because of the body's natural immune response, and people are getting blood clots for the same reasons they always have. But something tells me you knew that already
@@Chris_winthers yessir. I'm much more educated about MRNA vaccines.
As noted by others. Whenever your immune system reacts to something the resulting symptomatology reflects the areas of the body impacted. In other words if you catch say the Flu to develop mostly respiratory symptoms that is because the Influenza virus can infect those cells in the body to cause an inflammatory/immune reaction.
So the SARS-CoV-2 virus antigens - your "protein spikes" - have a high affinity for ACE2 receptors found in the body. Those receptors however are ubiquitous being found on cells everywhere in the body - especially your cardiac/vascular tissues. This means the virus itself and the resulting protein spikes created by the mRNA vaccine can attach to cells throughout the body to trigger an inflammatory reaction.
So your body raises its temperature - read an inflammatory reaction - which may or may not defeat infectious pathogens which can only survive in a given temperature range. You feel "achy" because more blood is being shunted to your muscles/extremities - vascular dilation - which helps immune cells get to where they are needed. More blood in your extremities means less for your core system like your brain - hence headaches and so on. These are all "uncomfortable" - albeit necessary - side effects of an immune reaction.
p.s. - people hospitalized with actual Covid also develop blood clots as well = in far greater numbers than the rare cases seen with certain vaccines. Clots are a reaction to = inflammation - which as noted above the Covid virus can cause on a systemic level given its ability to impact cells throughout the body.
As a Hungarian I'm super proud that the basics of the mRNA technology were laid down by Katalin Kariko, a fellow Hungarian. She's a real hero.
Not really, it was doctor Robert Malone. She figured out how to get it into the body.
"In 1961, the biologists Sydney Brenner, Francois Jacob and Matthew Meselson discovered that RNA transported genetic information. They also found that the process could be used to produce proteins in cells.
But it wasn't until 1989 that virologist Robert Malone managed to demonstrate the process.
Researchers carried out the first laboratory studies with mRNA vaccines on mice in 1993 and 1994."
Now I understand better the allergic reaction aspect to some of the vaccines
No one has been able to answer the below.
How long does the 'spike protein' created by these vaccines stay in your body ?
Does the 'Spike Protein' enter the brain and other organs in the body ?
The spike protein is produced in cells around the vaccine injection point. I think it goes into the blood from the muscle it is injected into, but mostly stays in the muscle tissue. Hence why people have a sore arm after the shot. The soreness shows the body is attacking the cells that produce the spike protein. The cells that have the spike protein are killed and removed. I believe the blood brain barrier stops any of the vaccine going into the brain.
@@patientestant Yep, also the vaccine is localised only. It doesn't travel around the body, and it ideally doesn't enter circulation, only enters the lymphatic system where out immune cells live.

Honestly, even if the mRNA got into the nucleus, it wouldn't cause any issues. Humans don't innately have any machinery to translate RNA back to DNA, so there's no genetic modification going on. And even if we did somehow make DNA copies of the vaccine's mRNA (reverse transcription is the term), the chances of it actually integrating into the cell's genome is EXTREMELY small*.
*This is due to a host of reasons, but a big one being that our cells actually contain a large number of enzymes designed to break down foreign DNA and RNA, as well as recycling our own cells' molecules. This means that free-floating DNA and RNA generally don't last particularly long--which has been a great evolved mechanism against viruses.
I don't know why I had to get so far down in the comments before someone stated this. mRNA really is a 1-way path in protein fabrication; it's essentially a Xeroxed copy of the blueprints (DNA) for the protein; a copy that is meant to be shredded right after use.
@@rydaddy2867 Kind of like old, cheap Xerox copies that came out white on black, too.
Why can't we just produce the antigens in a lab and inject that directly? Is there no generic cell that we can use to produce antigens outside of the human body? Why do we have to make our own cells produce the antigens?
You’re talking about how other vaccines work. We already inject antigens. This method is newer and tries to do it more efficiently
Fewer rejection reactions with straight mRNA. 20th century vaccines are quite 'dirty" that way; I have a family member who has not been able to take flu vaccines until recently because they were cultured in egg.
Right, why not just do the tested and old faithful that’s working for hundreds of years. Why tamper with our mRNA. Then mandate people to try a product we are still studying?

The vaccine is benign. It's possible it may not work or work long term but it should not have any serious long term consequences for most people. Yes we are playing a game and making the rules up as we go along but if we do nothing then we will never contain the virus.
@@donnash5813 with some mortality rate as low as it is and the demographics of the people who have the highest susceptibility to have symptoms and die and all the very effective treatments that have been developed I don't think it is necessary that the vaccine be mandatory or be required for travel or work or school.
@@despaahana I don't think it should be mandatory for everyone either. The vaccine was rushed and we are all a big experiment. My point is the vaccine is benign for most people. The J&J vaccine seems to cause blood clots in some people which is why it was pulled from the market for a while. The drug companies and health organizations will be keeping track of how well the vaccines worked for years into the future. I just feel the vaccine is our best chance to beat the virus especially as it is mutating.
Why would there be a difference in time that a memory cells sticks around or is able to remember to provide protection from an antigen that is created from an mRNA vaccine vs more traditional vaccines? Not sure if I used the right terms, but I'm curious about how you can determine how long a person will be protected and how that differs with the mRNA vaccines.
generally your memeory cells can last decades though they do dwindle in number if you don't get reinfected for a long time. The real concern is if the virus's proteins end up changing in such a way that still lets them infect you but doesn't let you recognize them. The only difference in duration you could see would come from dosage. how big of a reaction does this vaccine elicit compared to a normal one. that kinda thing.
It differs between vaccines, between different illnesses and between different people. These values are subsequently determined statistically. It is too early now to tell, maybe there will be an annual vaccination like for the common flu.
I don’t think there is a difference in how long the protection would last. The protection only wanes as the virus out in the world mutates such that the memory cells no longer recognize it.
How long vaccine provides protection is very complicated so they don't actually know how long it will last. I think some covid vaccines (not in the USA) are not mRNA based, so we will likely be able to at least get a rough idea if the longevity is similar or not.

To elaborate on Sam's (correct) point, they're different vaccines, they're under review (so we don't know the cause yet) and the rate was literally less than 1 in a million so that'd still be an acceptable risk if we didn't have alternatives.
the spike protein is what allows covid virus to attach itself to cells. if mRNA goes inside blood cells the blood cells will produce the spike protein and with other nearby blood cells they will get clump together causing a blood clot just hope mRNA doesn't enter blood cells
@@tttpppbbbaaa That's not how it works. Please don't misinform people.
Why did they reinvent the wheel while hundreds of thousands of people are dying?
They didn't.
Oh, so it didn't take a whole year to roll out a brand new type of vaccine under an executive order called "warp speed", and all of last year totally didn't happen.
@@akabga we already had mRNA vaccines. We've already been running mRNA trials for other diseases. We've been doing it since SARS-CoV-1 (2003-2004). The approval has just been sitting in the government offices until COVID came along. It only took a year because they had to re-do whatever they did but for SARS-CoV-2 instead.
@@PixlRainbow Like, there weren't other, quicker, more viable methods that have hundreds of years of documented success. Nope. We had to "re-do", such as "reinvent", like a wheel, or something along those lines. 🤔
Like I was saying.
@@akabga the hundred year old methods would have taken more than a whole year. We would have to re-do everything with those too. SARS-CoV-2 is a new virus after all.
Kinda missed how the mrna get transfered from the syringe to the desired cell...
Does it get introduced into all types of cells (or most) and they display the spike proteins or only immune cells can display them?
If the mrna transported via exosome, how do we prevent it from fusing to any or all cells?
Finally I've been watching this channel for many years and I don't know if it's me or this presenter in particular but I've noticed that more than explaining a concept it seems much more like it's being read. I know it IS being red, but I've been noticing the explanation "too much" as if they're reading them.
Anyways keep it up as always!
The mRNA is encased in a lipid membrane. JUST LIKE ALL of your cells are. This membrane will fuse with some cell membranes and deliver the mRNA into them, which then are picked up by the ribosomes etc. etc. etc.
@@rickkwitkoski1976 "how do we prevent it from fusing to any or all cells?"
@@ModernWelfareThree These nanoparticles will fuse with all cells they contact. Mostly with the cells presented in muscle tissue, however the nanoparticles may also go to a bloodstream and potentially can transfect any type of cells. I don't know if these nanoparticles can cross the Brain-Blood barrier or Placenta-Blood barrier.
@@Kostochkin Do you have source for these things getting to blood stream? Or did you just make that up in your little conspiracy head?

I really hope Katalin Karikó and Drew Weissman get a Nobel Prize for their work to make mRNA vaccines viable. There's a great article in Stat titled "The story of MRNA: From a loose idea to a tool that may help curb Covid" about the history of its development.
It would be really cool to have another woman win the nobel prize! Not because women should get nobel prizes, just for being women, obviously, before anyone understands me wrong, but it's just cool when a woman has participated in important research and it's recognised, so people see that women can do great things as well, so more girls are inspired to go into science! Especially when it's about such an important topic like the way to end the pandemic.
I'm a woman wanting to go into science (I'm in my 4th semester at uni), and my role models were my dad (who has a PhD in physics, but doesn't work in science anymore, and who encouraged me to pursue science) and Irene Pepperberg.
Katalin Karikó could be a role model for many more girls to come, so it would be really neat if she got the nobel prize!
@@solar0wind Wholly agreed. Especially considering how many women did nobel-worthy work only to have their male colleagues receive the prize. Women like Jocelyn Bell Burnell, Chien-Shiung Wu, and Lise Meitner come to mind but there are certainly others.
Personally I see it as a great shame that academia was a "no girls allowed" club for so long. It's disappointing to think of how much more we could have learned by now if not for excluding half of the population from the means to discover and share their discoveries.
Though, while I agree representation matters. It seems now an additional issue is some men in academia doing their darndest to make women feel unwelcome. It doesn't help to drive women into science if when they get there they want to leave before long. I hope those doing this are merely a vocal minority. We've made progress but there is still more to do.
I wish you all the best in your academic journey and I hope you'll remember that you belong there just as much as anyone else. Anyone that tries to make you feel unwelcome is merely expressing their insecurities. Also I knew of Alex the grey parrot but not Irene Pepperberg so it seems I have some reading to do. Cheers to your father for being a great role model :]
@whesley hynes who said anything about women torturing animals?
@ the 4 min 55 second mark you mention that past MRNA vaccines never made it out of clinical trials. You also say that in the past “they were unable to get them to work properly, but these two new vaccines do work.” How specifically do we know they work? Especially since their was almost no time to test them? Asking for a friend.
The reason we know they do work is because of the same large scale case studies that get performed with any other vaccine in trial, where a large number of people are monitored for two things:
-Delta of Rate of infection
-Delta of higher severity cases
Delta describes the difference in cases compared to a non-vaccinated control group of the same size, tracked over a set amount of time.
I.E., if you see Biontech's "90-95% secure", that means that these studies have shown a total of 90-95% less infection and/or severe case developments compared to the non-vaccinated group.
Again, note that these studies are the same performed for every single vaccine out there. They do not differ due to the vaccine type.
Damn I’ve never been here so fast. But also the concept of the mRNA vaccine is so useful and amazing.
ok

Why people having horrible reactions some life threatening and some dying shortly after?! Now I've seen and heard about shedding to people that haven't got it
Because this wasnt fully explained in this vid. The mrna coding actually uses YOUR ribosome. In this vid, they said "a." Sounds trivial, but to an unsuspecting person, they wouldnt know how important language is. It sets off the red flags when you need to know something is amiss. So, the coding (so they say!) is for a viral spike protein & then it uses YOUR ribosome & YOUR trna delivers amino acid. All that together grows a spike protein that is part viral & part you. After that, you make antibodies against not just the viral spike, but the combination of spike & yourself. Basically, the ones who get this are the ones that need to make sure that they dont get sick with something that has that spike in the future because it will go for more than just that spike. As for the terrible reations, since your body NORMALLY destroys foreign mRNA, they had to hide it in a fat pock called polyethyleneglycol (PEG) to bypass your body's defenses & get to your ribosome. Some people will absolutely have anaphalctic reaction to PEG that can be deadly. The other possibilities are: 1) your body was never meant to make proteins that are not for itself so as the entire body tries this, its too much 2) not all vials contain the same dosing 3) not all vials contain the same coding? Is it possible experimentation on how to turn on & off genes to have certain things happen is also being experimented with? Perhaps. I mean we saw at the beginning, tremmors & bells palsy, then later a huge amount of eye disorders in the UK, now, we are hearing of fully body rashes & blood clots. Its just a little weird how these reactions have "groupings" of types. 4) its possible they came into contact with a naturally occuring RonaV shortly after their body started producing antibodies & (remember they are trained for part v, part you) now they have an autoimmune/self attacking response, instead of a more natural, "just going after the v" response like normal vac technology is supposed to train your body to produce. ... also, viral shedding is a thing, so since a person GROWS the viral protein when they get this, shedding eventually occurs.

@@Bryan-Hensley It’s good when scientists admit that they’re not 100% sure of something, it means honesty. Heck, even a 99.7% safety guarantee still means a small chance of something going wrong, doesn’t mean the costs outweigh the benefit, they don’t.
Stop instilling fear in people, to hell with your misinformation.
Just got vaccinated and the fact that it was rushed and that it was a first time thing was really creeping me out the more I thought about it. I’m no virologist or geneticists, so I knew my fears could be baseless(that also means I don’t fully know how to feel about this video), but this vid eased my fears a bit.
mRNA vaccines have been used in veterinary practice for a while now, this is really just the first use on humans, but even so they should be safer than traditional vaccines.
also the rush was more about skipping most of the red tape rather than actual safety procedures

Nicely explained. Thanks much.
Now, it's found that they do enter the nuclei of our cells.
where you read this at?
Ah yes, the classic source of "trust me bro"
Oh, and Even if it could, nothing would happen
wait is it making antigens or the spike protein that then the body reacts to and makes antigens and then white blood cells recognize it. Also make it sound as if the spike proteins come out of the cell that reads the instructions and makes them so then the immune system destroys those cells? how does the mRNA get into the cells and which ones? Also I understand it wont edit our dna but can another virus integrate this into their dna say you are already sick with something that could use this and when it reproduces it has those instructions now. cuz isnt the spikes what made sars-cov-2 so contagious?
1. so then the immune system destroys those cells?
Yes
2. how does the mRNA get into the cells and which ones?
the cells are random. It's whatever the mRNA bumps into first. It will usually be a muscle cell since they are injecting into your upper arm muscle though. The mRNA is wrapped in a bubble of oil, and your cells outer membranes are also made of oil, so the bubble dissolves into the membrane and the mRNA gets dumped into the cell along with it.
3. can another virus integrate this into their dna
RNA is chemically a different molecule from DNA. You can't join them together.
Got my first vaccine today. Crossing my fingers that I'll evolve and get super powers.
I know a bunch of furries that got it just because they heard a rumor it can turn you into a crocodile.
What cells do the vaccines target, and how do they get them to do so? Or is it just whatever cells they come across first?
@AvengeVoltaire So the vaccine doesn't do the targeting; it's there for the immune system to find and begin operations against?
The nano lipid layer around the mRNA is attracted to any and all plasma membranes, which means technically it'll fuse with any cell with a membrane. Which is all cells. Because of this the chosen injection site is the deltoid muscle. It is so densely packed with muscle cells, injecting into the blood stream directly is highly unlikely. So the main cells affected are the muscle cells as well as dendritic cells (APCs). The dendritic cells would be chilling in the lymph nodes which the vaccine can reach via lymphatic circulation (different from blood circulation) thats easily accessible from arm, cuz we got a lymph nodes in our armpits.

/Everyone/ needs to see and understand this
How does the mRNA control for how much spike protein is produced? And when there is enough of it in the system, what signals it to be shut off (to not produce anymore spike protein)?
There is no control. The pseudouridnated mRNA hangs around for months in the body in places like ovaries, heart, etc. and the amount of poisonous and inflammatory spike protein it produces is highly variable so the injectee is essentially getting an uncontrolled dose of a very harmful protein. What could possibly go wrong? ;)
@@dfikar that's exactly what I suspected......that's scary....

I've been wondering this! Thank you!
Do our cells really "display the finished spikes on the [the cell's] surface"? I was under the impression that the spikes get broken down into antigens that somehow make it out of the cell to get attacked (I'm not sure exactly what happens tbh).
One of my friends suffered through an auto-immune disease a few years back, and currently refuses to get vaccinated because he believes that, like in the visual part of the video at 3:49, the immune system is attacking our own cells with the spike protein somehow expressed on the surface (Auto-immune fear of some kind). Idk if he got his information from scishow, but maybe there is more proliferation of this kind of misconception (?) causing a bit of fear for those with auto-immune diseases.
You are right the full spike created inside the cell is broken down in the cell and the pieces are expressed and anchored on the cell surface.
It is nothing more than the protein that is created and it is the same protein that the spikes are made out of on the covid virus. When that virus enters into your system it already knows what to do because it's the same protein.
Both, it depends on what cell the mRNA enters. If it enters a type of cell called a dendritic cell, then it would be processed and presented on a MHC molecule so other immune cells can see and recognise it. If it enters another immune cell, it'll induce production of the spike protein to it's surface, to which other immune cells can recognise it and mount an attack on the cell. So our own cells that express the spike protein do die, but its a very limited amount (limited by vaccine dose), because there is no virus replication going on, so what we are injected with is what we get. Yes our cells are attacked, but a comparatively small amount. Autoimmunity happens when a self-reactive cell escapes into our circulation and attacks our own cells. Everyone has self-reactive cells, normally they are cleared away through several selection processes.
What are the long term effects of this technology?
Something not explained is-what is the protein made by the cell ribosome that is coded by the mRNA from the virus. Is it a protein the cell normally uses but just a piece put in by the mRNA code. Or does the mRNA create an actual protein specific to that mRNA in the vaccine.
Now I understand why people get sicker
to the best of our knowledge they are safe...hmmmm
This is a good basic video, but I'm really interested in the two topics you hinted at here:
4:37 -- Researchers had to figure out how to make the RNA molecules last long enough in our bodies to actually get translated (into the spike protein) -- how did they do this? Why did it take so long? How were they able to make it happen so fast once the pandemic struck?
4:46 -- They had to work out the perfect delivery vehicle to get the mRNA into cells, and minimize side effects -- these were the famous lipid nanoparticles -- more on this? Inquiring minds want to know.
Go watch their previous video about mRNA vaccines, they explained all of these.
Are you talking about the "hydrogel"? That is the nano part.
of the vaccine.
Also interested in how they managed to speed this up over the pandemic? Funding maybe? 🤔
who tf would dislike a video like this..

On Tuesday, June 28, FDA’s VRBPAC committee will meet to discuss and vote on a “Future Framework” for evaluating the “next generation” COVID-19 shots. If approved, this allows vaccine manufacturers to bypass the regulatory process and skip clinical trials of newly reformulated COVID shots, in perpetuity.
Anyone know what exact cells the mnra vaccines actually utilise
Good question! Red blood cells? Muscle cells? I hope someone has the answer, I am curious.
The nano lipid layer surrounding the mRNA is attracted to any cell membrane, this is why the chosen injection site is our deltoid muscle, because its densely packed with muscle cells which means the injection is unlikely to be delivered directly into our blood stream. Due to this, the main cells that mRNA will enter are muscle cells but also dendritic cells (APC). The vaccine can enter our lymphatic system to go to our lymph nodes where most of our important adaptive immune cells (dendritic cells) chill in.
You say a lot of things very confidently followed by “as far as we know”
I love how they stated it is safe and effective too. All while saying how not a single mRNA vaccine has ever made it through trials (What they didn't state: because they all failed long-term studies).
SciShow didn't even hint at any concern. Stated it is safe despite all mRNA vaccine history showing it is not safe. They didn't even say for pregnant or breastfeeding women to be cautious.. Getting pregnant/breastfeeding women involved in a clinical trial deserves criminal charges.
Thanks a lot! I wanted to know how it worked for a while, but never made the efforts to look it up😅
Several channels here on YT have already made similar vids months ago. All of this basic stuff has been given out to the "public" for some time already. Problem is, most people don't try to learn anything, they wait to be spoon-fed! Stay well.
Many people here worries about AD, (auto immunity disease) after artificial vaccine shot. If people have immature innate immunity, there this chance increases. That's why the most side effects are mainly occuring within young women. They usually does not much live outworld life and has also short time or history to contact innate immunity or pathogen.
Above chance are more risky when they get cought with real virus, but vaccine has no big risk because the mRNA injection amounts are small and it has no power to cell life mutation. But eventhough our body immune cell mechanisms are so complicated. So there is no gurantee and they have to be careful.
The only way to overcome above matters are everybody train self innate immunity everyday before things happen in their body.
We can finally start growing our tails back
Its turns out They where not safe 😉
What a simplistic information about the vaccines. It is like teaching at kids at the pre-school level. I think it should be a little more elaborated. And answer some questions: what is the carrier that take the mRNA to the Ribosomes? If they do not integrate to our genomes, how are we going to guarantee that they will maintain the production of the spike proteins long enough to give us immunity? What are the negative effects of those spike proteins?
Thank you, it's explaining what they are and what they do in a simple and short way. I'm getting my shot (mRNA) in a couple of days and I'm a little nervous.
i got mine and it sucks symptom wise so make sure you can take time off for a few days when needed. :)) unless you have an allergic reaction you’re fine
Don’t do it!
Just be glad that you won't get AstraZeneca😂 It's a good vaccine, but the side effects feel like a bad cold. My boyfriend got the first shot last month and suffered a lot for two days, so it was quite unpleasant, but now younger people aren't supposed to get this vaccine anymore here because of a one in a million people side effect basically, so it's unclear what vaccine he's gonna get for his second shot.
@@solar0wind it’s very risky though, I wouldn’t call mRNA ‘good’.
@@maxmorris4562 mRNA is good though? What are you talking about, without it we would all be dead

Each of those cells is a Wanted poster. They are intended to be mobbed for practice.
The fact is, the manufactured pathogenic spike protein units are NOT displayed on the muscle cell. Instead, as the pathogenic spike protein units are manufactured within the cell, the cell swells and then bursts, releasing the pathogenic spike units. Hint: Look up "endotheliitis"
No, the cells actually release excess spike protein in little packages, to prevent that from happening.
