Scientists are reporting troubling signs that some recent mutations of the virus that causes COVID-19 may modestly curb the effectiveness of two current vaccines, although they stress that the shots still protect against the disease.
Researchers expressed concern Wednesday about the preliminary findings, in large part because they suggest that future mutations could undermine vaccines. (Snip
One way vaccines work is to prompt the immune system to make antibodies that block the virus from infecting cells. The Rockefeller researchers got blood samples from 20 people who had received either the Moderna or Pfizer vaccine and tested their antibodies against various virus mutations in the lab.
With some, the antibodies didn't work as

Who cares. Let's move on.

This is always the case with any RNA virus. RNA viruses are inherently unstable in their 'blueprint' (RNA), so they drift, accumulate errors and damage. This can make them more virulent, less virulent, or suddenly no longer deadly.
RNA viruses always mutate/drift. Not news.

The point is not that RNA viruses mutate. That is stating the obvious. Most are fully aware of that. It’s the reason why there is a “new” flu vaccine every year.
The point of this research is that the vaccines being highly touted and given to masses of Americans may well miss the mark.
It really does help to read the articles in full.

This vaccine is as useless as the yearly flu shot and the non existent AIDS vaccine which that little troll, fauci, has been working on, slurping at the government trough, for over 40 years.

This is how they will control us. This virus is starting to act like the software on your I-phone. We had COVID-19 and we developed a vaccine for it, but, guess what, we now have COVID-19.1. And, it won't stop there. Whenever the democrats want more control they will roll out another version. Like how about COVID-19.2. The freakin Chinese economy is growing while the rest of the world is suffering. Yet, the only person who laid the blame where it should be was PRESIDENT TRUMP. And he was right, the Chinese now run our country right threw the oval office. Do you get it yet.....

#3, I read it, and yes, the vaccine may not work perfectly against the Wuhan flu as it changes. That is obvious for any vaccine to ANY RNA virus because they change. Perhaps it is not clear to the layman, but it is clear to anyone who has learned what DNA and RNA are, and how the two classes of viruses differ fundamentally.
RNA viruses are moving targets, continuously accumulating errors and changing, unlike DNA viruses such as smallpox, which has remained very stable for centuries, and therefore able to be reliably vaccinated against. All RNA viruses are unstable over the long term.
This is why we have annual flu vaccinations. For several reasons these vaccines are not 100% effective, one of which is the flu virus' steady mutation, but they are generally helpful to reduce your chances of getting the virus, and if you get it, reduce symptoms and recovery time. It is likely to be the same for this vaccine, imperfect but likely helpful.
However, there is more to it. This is not a conventional vaccine, it is very different, in a potentially disturbing way. A conventional vaccine puts protein chains into you body which mimic the virus external protein structures, and teach your immune system to recognize those protein structures as "other" and attack them, building antibodies.
These two 'vaccines' use messenger RNA (mRNA) which enters your cells, and like a virus, takes over the cellular machinery to produce protein structures which then are released into the body from your cells. These protein structures are what the immune system responds to by creating antibodies, as it would if these protein structures were injected as the vaccine.
So, these 'vaccines' are actually just instructions to your cells in how to make a vaccine, not a vaccine themselves. That is different, never having been used before in humans. A bit unsettling, frankly. Certainly, testing seems to show good results, and this method is much faster to synthesize in the lab. One unanswered question is: Is this a 'one and done' thing with the mRNA or does the mRNA get permanently encoded into DNA? I have not seen a good comment on this at this time.
My cellular biology prof friend and I have briefly exchanged emails over it, and he is 'sort of' OK with it, but is very busy on work and will look into it more deeply in a few weeks to understand precisely how it works, specifically commenting on whether the mRNA is used once or permanently encoded....which he commented would violate NIH rules.

Thank you, #6. I've been trying to explain to my elderly parents and young friends this is not like your typical flu "vaccine". It is a "Messenger RNA" injection. Be a Berean, folks. Do your own research.

I just don't care anymore. It's a virus, and that's what viruses do.

#8, no, that is not correct. DNA viruses, like smallpox, are unchanged for centuries.
