Doesn't giving a coronavirus vaccine to everyone increase the chances of
the virus mutating to avoid the vaccine? So we should be using it
sparingly.

Good point actually.

Nope, shows a complete misunderstanding of how viruses mutate.

Only if you take his "everyone" literally and assume that it is 100 percent
effective at preventing "hosting" the virus.

Doesn't need to be anything like 100% effective at reducing
the chance of getting infected to radically reduce the number
of hosts that the virus can reproduce in. That's the only way
it can mutate, by reproducing.

Yes, it needs a host.

It seems you don't understand how viruses mutate

My original statement is completely accurate.

I didn't say it wasn't, I said the OP had a good point.

or how vaccines work.

And so is my later elaboration on that too.

The best of the covid vaccines have been shown to dramatically reduce the
rate of covid infection in the vaccinated. They don't just reduce the rate of
severe infection and death as you previously claimed in another of your
posts.

I didn't say that. I said:

"vaccinated people can still host the virus and spread it to others"

This means that while hosting the virus their systems present an
environmental selection against the currently targeted shapes of the
various vaccines' antibodies.

My point exactly. Why have a vaccine if you can still pass it around? And even more importantly, having the vaccine means people are less likely to take other precautions, more likely to host it and more likely to be showing the virus how to mutate.
