I'd argue that it's worse now. Where I live we have over 20% vaccinated right now and that number increases every day. This adds a bias for mutations that are vaccine resistant. A mutation that gives a slight disadvantage, but means the vaccine won't stop it, would have gone nowhere a year ago. Now that same mutation has a large population where it can easily outcompete the current virus.

That's a good point. I guess the worst situation would be almost herd immunity, with the majority being vaccinated but a minority of unvaccinated people constantly circulating the virus. The vaccinated population then represents verdant fields: https://www.youtube.com/watch?v=yybsSqcB7mE https://www.youtube.com/watch?v=yybsSqcB7mE
