      Think of each of us as a Petri dish. The more Petri dishes exposed to the virus, the more opportunities there are for genetic mutation. If fewer Petri dishes are exposed, there are fewer total viruses in existence, less replication, and therefore fewer mutations will arise. This is how social distancing, mask wearing, and lockdowns prevent mutations-there are fewer Petri dishes exposed to the virus.
      For those unwilling to be vaccinated because they “don’t want to be a guinea pig”, they are unfortunately already part of nature’s experiment. They’re volunteering to be a guinea pig in the control group.

    Hi DJ, nice talk on viral biology. Just to be clear, high transmission/infection = higher virulence probability.
    In the lab if you want to up viral virulence, you speed up the certainty of viral transmission.
    When a virus has certain transmission, virulence goes up - eg, it has no need to worry about killing the host.
    So in a viral pandemic it is worth keeping the number of infections down, to slow transmission, in order to lessen the risk of more virulent strains evolving.

      The nurse guy here is also held by the balls. Pharmaceuticals will immediately come after his UA-cam channel, his reputation and potentially his pension if he actually addresses this. So, he sidesteps it by saying "it's bizzare, I don't get it" or something to that effect... and keeps himself on their side by spinning everything to be pro-vaccine in general.

Oxford originally was going to partner with Merck, a world-leading vaccine producer/distributor (and the originator of the technology Oxford is using). They however chose AstraZeneca who had very little experience instead because of the potential to earn more money in the long run with AZ (reportedly 6% royalties vs 1%). Another reason given was that Merck is an American company while AZ is a British company and they were worried about how that might impact deliveries to the UK.

    Dear Dr. Campbell, Thank you for your clear and understandable explanation of how this virus is spreading.
    For a long time, I wondered as to how, with people seriously following the health department guidelines, the virus seems to keep on spreading anyway...like it has a "mind of its own." I kept asking, Why?
    Your explanation really helps.
    There are people I know, who have quarantined this past year, always ventilate their apartment, wear masks, hand sanitizers; who make one little mistake: go out to do something, and end up in the hospital. It seems so unfair. Your diagrams showed how easy it is, to catch the mutated virus from breathing the air. How bad the result will be depends on whether the person is vaccinated (with immunity built up over several weeks)...or not vaccinated.

      Fred Chapman, There is an old saying here: If you get tired of the weather In Texas, don’t worry it is about to change. I have lived here my entire adult life after living in Europe in the early 60’s, the Far East in the early and mid 70’s and all over the states between. That saying is quite true. But this winter that shut much of the state down took the cake and tossed it out the window. In my household we were fortunate in that we had power but no water. Many did not have either. I had to get my 96 year old father in law as he had no power or water and his house was cooling rapidly with the temp outside at ~20 f. with 2 feet of snow and ice on the ground in central Texas. Fortunately I have a 4 wheel drive vehicle. The high wind had drifted the snow to 4 feet on the empty highway. When I left to get him I didn’t know if I would make it. I was not scared, but worried about my family and just kept moving forward. I have lived through blizzard in a tent In Yosemite where I worked at the ski lodge. But this was bizarre. 2 inches of snow once every couple of years, yes but 2-4 feet with ice and high wind not in Austin. We had to collect snow and ice for the better part of the week for toilet and dishwashing. Then we had to boil the water for several days when it came back on. And we were the lucky ones. Sorry that got long quick.

      Fred Chapman, Hi there, Fred. I was on the roof clearing branches and wet leaves off today for 3 hours, but will still take my D3. We have many huge trees in Austin and it is not very much like the rest of what people think of Texas in many ways. It is one of the greenest cities in the country. And that winter storm brought a lot of trees down. Huge trees come down everywhere, on houses, block streets. We first had an ice storm that coated every exposed surface. Then the wind came and the branches and huge oaks started falling and then power lines started outages the first night with the thick ice. Saturday the snow started with more wind and ice Sunday. Monday most of the State was shut down and nobody went to work for most of the week. Austin, Houston, Dallas and hundreds of small towns started losing power that first night with the ice. I have lived on a small island for five years and we would get hit by a couple powerful typhoons every typhoon season. I have forgotten most of them, but I and my family and many thousands actually millions will never forget about this winter. We are grateful to be able to tell the tale.

      @MarcosElMalo2 3 роки тому +3

      It’s a bad point for misunderstanding. The tendency towards less virulence might take decades or centuries to unfold. It’s better to think of there being an upper limit or ceiling to virulence. A virus that kills its host too quickly won’t be able to replicate and be transmitted for very long, and will burn itself out. However, a virus with a high rate of transmissibility has a higher virulence ceiling. With high transmissibility, there isn’t as much selective pressure on virulence.

So, even tho we are vaccinated, we are still at risk for contracting the new variants with, perhaps, a milder case. But, more importantly, we can be super spreaders of the new variants???? Is this correct? So my relief at being fully vaccinated and not a significant danger to others....well....that is dashed completely?

Coordinated Global Alliance for Vaccines and Immunisation’s , He believes he is now morally obligated to put his professional reputation on the line to get this scientific information out to the public, and has sent an open letter to the World Health Organisation highlighting the dangerous principle of mass using of a prophylactic vaccine that does not 100% eliminate infection and transmission in the recipient whist still in the midst of a pandemic which is highly likely to create super vaccine resistant variants in the process .

My idea has been all along that since SARS-COV-2 does most of it's damage *after* the viral replication phase it won't follow that pattern. Evolution influences that part of a lifespan up to the moment the offspring is independent. This year will be more difficult than last year. We'll see lots of variants winning the competition because they are more transmissive and they appear to be more dangerous as well. This is not the moment to let our guard down.

    Why can vaccination companies alter the vaccines for mutations WITHOUT doing a long exhaustive 3 phase double blind study to ensure their safety on humans like was needed for the initial vaccines?
    As someone who doesn't understand this stuff and learns it through your channel...the idea that companies can just change what they put into your body without extensive tests for safety and trials leading up to is concerning. But since you and others talk about this like its fine and normal makes me ask the question why that is.

      It's basically just a minor "tweak" to the code so that the s protein produced by the vaccine matches the new mutant spike protein .
      It's normal in much the same way that the flu vaccine is tweaked every year to match the new strains.

      @@bidentity69 These virus variants go through extremely minor tweaks and wreck havoc on the state of pandemic just because things were swapped or change on one or two of the sequences.
      Wouldn't these tweaks to the protein potentially have equally drastic effects on how the human body might respond to them?

      @@rogerbabin8175 Why would they ? The " havoc wrought" is caused by the "live" virus carrying the s protein , not the protein itself. No active virus in the vaccine , as far as the immune system is concerned , just another foreign protein.

      While in trials: "Speed it up, you're holding back"; Out of trials: "You took short cuts and inadequate testing". mRNA tech in development over 20 years, BTW.

      They can't do full length trials because the virus mutates so fast. They may be able to tweek the vaccine but manufacturing and distribution will never catch up to the endless mutations and variants. That's why I think other treatments are a better solution. Or just protected the elderly and vulnerable. I think it's about time the government told the truth that we can't save everyone and let those willing to take the risk be allowed to get on with normal life.

    I studied Immunology as part of my Clinical Science degree (I'm an Audiologist in the NHS) so your very clear, accessible explanations are really helpful in refreshing my recall of the topic. I have a question re: mutations. Are they really that random having now - across the world - detected the most prevalent/transmissible in 'pattern'? If so, might it be possible to computer model what might be the next wave of mutations and, if so, develop the next phase of vaccinations to head off the risk? I'm hypothesising here :-). I just feel like we are always chasing our tails and because - quite rightly - vaccinations and treatments need to go through rigorous safety/efficacy cycles, we are unlikely to completely become 'zero COVID' and this virus will become endemic as have so many before it. Of course I am hopeful that treatments and vaccines in combination, administered across the world, will mean we can, one day, see more normal life and travel happening as before.
