Doesn't giving a coronavirus vaccine to everyone increase the
chances of the virus mutating to avoid the vaccine?
Nope, it's the reverse of that, the virus can only mutate in
infected people and so the fewer that get infected, the less the
chance of it mutating.
Exactly!

So we should be using it sparingly.
Nope, we should be vaccinating as many as possible with the
best vaccines to reduce the number who get infected.
Yup. And they are nearing what they think is herd immunity in
New York. Amazing.
Dunno, nothing useful on that with

Gotta link ?
Did more looking into this. Need 70% to get to herd immunity:
It is COVID fatigue causing compromises I think, 85 to 90 percent is
better but 70 sounds more "doable" at this point in time. Not enough
IMO.

I have the same feeling -- but no evidence to back it.

I was thinking in terms of the US. But, yes, if there are mutations where
the
immunity is reduced then the idea of herd immunity goes out the window.

A relevant part:

"At this point, data is not yet clear on whether the vaccines from Moderna
and Pfizer-BioNTech, while highly effective at preventing symptomatic
disease, also stop the spread of the virus.

That part is just plain wrong.

Herd immunity is only relevant if we have a transmission-blocking vaccine.

And we now know that we do.

If we dont, then the only way to get herd immunity in the population is
to give everyone the vaccine,

Thats wrong too. It doesnt need to be everyone and
you get herd immunity if enough get infected too.

says Shweta Bansal, a mathematical biologist at Georgetown University in
Washington D.C.

In the U.S., the predominant variant now circulating is the B.1.1.7, which
is about 60% more transmissible than the initial strain that first plagued
our globe. Experts now believe a threshold of at least 80 percent of the
population would need to be immune to significantly slow or stop the
spread. That number could be even higher if more contagious variants
continue to develop."

And its even higher again with the indian and brazil variants.
