@@dididogster9994 that's not the answer..
And there are many, many homeschooled kids whose parents vaccinate them just like kids who attend public school. In my state, home schooled kids have to show proof of vaccination to the Board of Education along with the paperwork registering them to homeschool!
@@Bogwedgle what? Vaccines cause adults???
*Oh this is genuinely incredible, can’t wait to see what else they do!*
They could just murder all mosquitos... permenantly. That will end transmission.
make a vaccine so initially the side effects of malaria will be mitigated, but the final result being that they are more susceptible to other various diseases like HIV/AIDS to aid the final solution.

Yep.
The mumps are in my school and I don’t know who is and isn’t vaccinated but I know I am , it’s scary as I didn’t know it would strike my very own school , I’m glad we can save ourselves and others agenst disease and other stuff
Thank the anti-vaxxers for the sickness and deaths. Hopefully there are few, or none.
That sucks. All the best to you and your school.
If you are posting here, it might be the case that you are in the age range when the mumps is a particular threat to male fertility. At least the anti-vaxers might have some of their kids unable to breed.
Yikes im sorry. Wash your hands A LOT and I hope you and everyone else will be okay

Thank me later
We did a mouse study on Malaria in college. It was amazing what happened to their blood cells. Just shredded red blood cells everywhere. :(
I participated in a malaria vaccine trial study. They injected me with a vaccine and then malaria. I got malaria and develouped Gametocyte, there was a case study published on it. That was like 3 years ago. I hope it helped make this vaccine possible.
every data point aids in ensuring that this works well, thank you for your service to Mankind
You are braver than I
lol you're nuts
you are a heroic martyr; thru your terrible suffering you have potentially helped saved countless lives
Gomidacites? Can you clarify?
Smallpox was.
Polio was.
Fear of being preyed on was.
Soon, we will say malaria was.
As we advance technologically and we shift out living standard to a higher setting, we will refer to common ailments like cancer and the cold in the past tense
Polio… almost was
exurb1a eh? Unfortunately polio is still a thing in few countries even though it's rare. Bubonic plague is still a thing even though it's super rare, that crap can survive for centuries in soil. Many other diseases have animal reservoirs. There is always this one shitty corner of the world where vaccines haven't made it yet etc. Smallpox is so far the only human disease that has been completely eradicated.
Humanity will get there eventually, but it's not easy.

I fcking love science
Even at 40% this could potentially knock the hell out of malaria. The parasite needs to be taken up by a mosquito from an infected host. Even if 60% of the time (probably lower because not all infected hosts will get bit again while infectious) the parasite is able to complete its life cycle, this will dramatically reduce the number of mosquitoes that are carrying the parasite in the first place. There is no selective advantage to the mosquito (that I'm aware of) for it to carry the parasite. A non infected mosquito should be able to carry on their genes at essentially the same success rate as an infected one.
Well, I think animal hosts are a big part of the malaria spreading
@@piguyalamode164 I'd considered that as well I didn't spend days researching it but it seems the strain the vaccine targets is really a primate only strain. That being said there is 200 strains, 5 infecting humans. I'll admit to not studying it extensively however
Sterilised all of the mosquitos
Its good to see that donating to the cause is working.
Really, I think it’s more about showing people an example of a more-or-less average person donating than actually donating. One person doesn’t have much impact, but you can inspire others
TL;DR become the most obnoxious person alive and spam people with screenshots of donating
I'm glad to take what wins we can. Plus, there is always hope for the future.
With this, I am sure, in my life-time, there would be a step towards creating a viable HIV vaccine.
Right now there is PrEP which can significantly reduce the chances of HIV infection in high risk individuals. Unfortunately it is something which must be taken regularly and is hard to get in most places. On the bright side, it does seem to work and is definitely a step in the right direction.
Yeah, well a lot of progress has already been made so there's hope. 10 years ago having HIV was terrible. Today, HIV positive people can mainly live a normal life if the diagnosis is made in the earliest stages. Can't wait for what we'll come with in the next decade.
in the next 10 years maybe but let hope earth is still livable after that.
how old are you?
Haven't you heard?
There is a new barrier that prevents transmission now too.
So between prep and this hiv is essentially dead
As an African American whose girlfriend is Ghanaian and who will be taking my 1st trip there next week I find this extremely encouraging. I'm moving to Ghana permanently and she & I are talking about having children. The things I've read about Malaria and what it does to children there have nearly scared me out of my wits. I am very very very excited to hear about the development of this vaccine. Great video My Man.....you're really really good at what you do.
This is excellent. It will save so many lives
It's nice to watch the show progress over the years. Y'all been keeping me informed for quite awhile.

we need to make anti vaxxers illegal
@@zes3813 Come again? You seem to have forgotten some letters there buddy.
@Zes i had a stroke
There aren't too many anti vaxxers nowadays. Cos they're all dead from measles outbreak.
I'm glad scientists never gives up on challenges like this disease.
I've had malaria twice (on separate trips to East Africa). It's nasty. So glad to hear this kind of progress. (And, my memory of the stats for how many malaria would kill per year used to be twice what it is now, so the other progress is encouraging too).
This is so great! I know it isn't perfect and irradicates all of that, but it is a step in the right direction.
YAYYYYYY MEDICAL INNOVATIONS!!!! ALWAYS LOVE IT WHEN THE BEST OF HUMAN TALENT CONTRIBUTES TO THE THE GREATER GOOD!!!
Wait till anti vaxxers find this comment and go all nuts and start blurting out pharmas, doctors, govt, aliens and what not
YEAAAA!!!
Good job! thanks!
This is huge!
I pray this vaccine as well as the vaccination program is a success
Damn, a successful blood protozoan vaccine. This is crazy exciting, these apicomplexan parasites have some of the coolest and most intelligent acclimatization methods from most protozoan parasites. Hopefully, this won't lower the relatively low demand for parasitologists already lol
doubtful, parasites tend to be the most adaptable out of illness causing pathogens.
@@randomplugs Parasites are incredibly adaptable, I agree. Perhaps, this Plasmodium vaccine will likely promote rapid acclimatization of the parasite. I'm still sceptic of its longevity as much as you are. However, you should understand that parasitology is still a very very niche field. It's much smaller compared to fields such as pathogenic bacteriology or virology. The demand for parasitologists is low in general, especially in human healthcare. The research of the field is still primarily (By a great margin) in animal husbandry and veterinary sciences
Kids in Africa are gonna be like “SHOTS SHOTS SHOTS SHOTS SHOTS SHOTS”.
This is amazing, this is going to show how important vaccines are
How exciting!!
My dad was an airplane pilot in Africa and he got Malaria unfortunately. He didn't die from that... but it was a nightmare, until he died (from another thing)
There are a lot of scary things on this planet that can kiss us and a lot of them fight us from inside. Which is even scarier in some ways. I rather fight a bear than cancer or this..
Kiss me.
As someone who fought cancer and won... Nah, I'd rather have another round with the same cancer than fight a bear. I got an amputation for it years ago, but the treatment for my particular brand of cancer has progressed to the point of a single surgery being able to get rid of it.
Good job
Thank you soooooo much this helped me alot in my homework as i couldnt find an answer. Thank you so so much
I was going to make and anti-vax joke, but malaria is a big problem, this is a very good step forward.
40% chance of survival is better than 0%
I'm pretty sure it's never 0%
It isn't about chance of survival! A 40% effective vaccine means that 40% of people that were vaccinated become immune to the disease. Those that aren't immune generally still have the default chance of surviving if they get the disease.
The sentiment here is coming from the right place, but it's still wrong and it's very important that we correct such things. As said above, the effectiveness of a vaccine is not at all the same thing as survival chance of the disease it protects against.
@@woodfur00 Malaria kills in ~0.20% of cases.
@ZwiggyNPC#018
That's assuming that, before a vaccine, malaria infects 100 percent of people and kills 100 percent of those it infects.
Exceptionally awesome!
Wow, why is the audio so different in this one compared to the concurrent shishow space episode?

Karen’s making a flight to Kenya now to sell essential oils
I did my senior project on a proposal for a vaccine for malaria, though it was just an undergraduate propsal, nothing I would actually do. It is a really big problem, but because it doesn’t affect the areas of the world where most scientists are practicing (Europe and North America as well as small parts of Asia). This disease is so complex! I’m so glad someone has found a vaccine that works, even if it is just a little bit!
As someone who comes from a malaria area and have experienced it multiple times, this is good news. They found that with treated nets and other measures, reducing the amount of infected people in a region can result in fewer infections even amoungst those not taking precautions (herd immunity effect), so even a 40% success rate could result in significantly fewer infections that that stat might seem to suggest.
Finally the Far Cry 2 guy is gonna stop having attacks mid fire fights, good thing they are thinking about him.
Bet anti-vaxxers gonna be like: bUt iT cAuSeS aUtIsM
Yeah, just comment "go back to sniffin' your essential oils, karen"
If anyone's looking for an update, the best place seems to be the WHO website on their "Malaria vaccine implementation programme." Strong statistics will still take more time, but it seems to be looking good so far. From their article, "Increasing equity to malaria prevention through vaccination pilot in Malawi":
"So far, accrued safety data are very reassuring.
The pilot is progressing well, community acceptance of the vaccine is strong, and the programme is now on track for a review of RTS,S data and a potential WHO vaccine recommendation for wider use in sub-Saharan Africa as early as October 2021."
Happy World Malaria Day! (April 25th)
back in the late 80s i went with my parents to kenya on vacation. i remember having to take thikk antimalaria pills even weeks before the trip.
awesome possum
good progress to fixing this
No one:
WHO: *You're now malaria free*
For how long?
That's not how you use that meme, I think. It conotes that no one was asking for a vaccine, yet we have a million deaths per year, no?
A whole continent full of no one's

Jokes aside, this could save countless lives and is an incredible advancment... Hope they some day invent some sort of Cancer Vaccine
If they did it would probably be different vaccines for specific types of cancer
That is regrettably impossible since it's your own cells that are the cancer and not some foreign cells (unless you're a dog or bivalve since they can actually contract cancer from another of their species or even in the case of bivalves across species lines)
@@IronicHavocin some cases but not necessarily...are you familiar with how they are working to make cancer vaccines?
@@ConstantChaos1 en.wikipedia.org/wiki/Cancer_vaccine
@@hpekristiansen yeah 1) that's a wiki article so it isnt really all that accurate and 2) by definition even if we were to take every strain of cancer we have ever seen and develop fully functioning vaccines for each within the decade there would be multiple new cases, cancers are all different and diverge extremely quickly, you can go from a single cancerous cell to multi-system endstage cancer with multiple different 'strains' of cancer within a year. The problem is that "cancer" isnt a thing, it's a classification of mutant cells meaning that 2 cancers can be different in every way
Thank Science! 🙏
That's awesome!
The editor is probably giggling to himself about that pun
Thank Science

Years ago while researching sickle cell anemia I read that having one of the gene gives improved malaria resistance two of the gene gives sickle cell anemia. Sadly, it was a while ago and I don't remember the citation. It would have been around 1990.
