Thank you for your thoughtful comment. I think the vaccines can still reduce the risks of transmission to some extent, based on the studies released thus far, although mostly unpublished. Plus, vaccines also reduce the risk of infection to begin with. But other studies in the future might show otherwise.

I also think that SARS-CoV-2 evolution would continue as long as it's not eradicated. And eradicating SARS-CoV-2 seems rather impossible at the moment, so maybe the best we can hope for is to suppress its evolution.
