>(if most people get vaccinated the virus goes away).

Polio. And these COVID-19 vaccines do not grant indefinite immunity.

95% efficacy is not realistic. We struggle to hit 60% with influenza vaccines.

We don't know how long the immunity from the vaccines will last.

The flu is a very different virus, so it's not really a useful comparison (mutates faster, etc).

I guess there will be plenty of proof in the coming months (in either direction really, it will be reasonably clear if it works as well as has been stated).
