If the virus is eradicated by vaccines, of course it will stop mutating. But of course it won’t likely be eradicated, but it will be given SIGNIFICANTLY less opportunity to spread and mutate if we vaccinate to herd immunity. That’s basic logic and biology. If you are trying to throw a 6 on a die, do you think you are more likely to get there if you have one or two throws of the die, or if you get 100 throws?
Similarly, do you think there are just as good odds for the virus to land on a worrying new mutation if it is given, say, only 3 bodies a day in which to replicate vs Brazil with 100,000 infections a day?
Is the answer not obvious? We don’t need perfection, but we can get significantly BETTER odds of the virus posing less mutation threats when the number of bodies are taken away as vectors.
Of course! Aren’t you aware of the many vaccine successes? Polio, Tetanus, Hepatitis, Rubella, Measles, Whooping Cough, Rotavirus, Mumps, Diphtheria etc. All these have been well controlled in societies that have high vaccination rates for those diseases. They mutate to a degree, but they aren’t running rampant through the world’s population so aren’t given as much chance to mutate as COVID is seeing now. (And, some mutate less often than COVID, no doubt).
Some do, some don’t. Have you noticed less virulence in rabies lately? Neither have I.
In the case of COVID, there’s evidence it has become MORE lethal either by simply becoming much more infectious hence causing more deaths, and/or by actually being more lethal (as there is some growing evidence).
First: the implication of your citing that paper seems to be that giving the population a vaccine that is not 100 percent efficacious against COVID infection is ill-advised.
You must know that this is a form of “anomaly-hunting,” right? You must know that the proposition is rejected almost unanimously by virologists, immunologists, disease transmission specialists etc, virtually all of whom are recommending to get as many people vaccinated as possible. Right?
You must be aware that the experts who UNDERSTAND how vaccination works have heralded vaccines like Pfizer and Moderna as amazing and welcome accomplishments in vaccine development and efficacy.
Why would experts who know what they are talking about say these things? Could it be that they actually understand the nature of vaccines better than you do? And that maybe going on anomaly-hunts like the one leading to that paper (likely spread around vaccine-hesitant social media) isn’t exactly the best way to understand what is going on?
Also, the general relevance of that paper should strike you as immediately suspect. NO vaccine is 100 percent effective. And yet many vaccines, like the ones I listed above, have been HIGHLY effective in stopping or controlling those diseases. Doesn’t this tip you off that drawing an implication from that paper to hesitancy about the COVID vaccines…hesitancy that experts don’t actually have…is a bit misinformed?
Do you think maybe that Israels amazing dropping numbers of deaths, hospitalization and cases of infection are just a coincidence given their world-leading vaccination campaign?
Why aren’t vaccine experts up in arms about the COVID vaccine? That paper went over some well-known subjects at the time, and many experts weighed in on the implications. Here is one expert, whose view was echoed by many others:
**Prof. Adrian Hill, Director of the Jenner Institute, University of Oxford, said:
“The change in Marek’s disease virus after vaccination is the rare textbook example of vaccine-driven viral evolution, and has been known about for many years. This paper provides experimental data consistent with that understanding. But it does not explain why, importantly, there is no evidence of this happening with other vaccines especially in humans, where many vaccines are used safely in millions of individuals every month. The suggestion that altered pathogen virulence should be looked for after vaccinating people is not new, and there is no evidence that human vaccines have produced more virulent pathogens. So, it is important not to claim from this example in chickens that this is a problem with vaccines in humans. There is strong evidence that widely used human vaccines are not producing any such effect.”"
