It would put pressure to avoid the vaccine. However: 1. There would be fewer cases compared to unvaccinated people to give it the chance to mutate. It doesn't have any more chance to mutate among vaccinated people. It has less chance. Just a lot of mutations that still look like the current virus will get killed off by antibodies. 2. Randomly making changes to the spike protein, this virus's most important part, is likely to reduce the virus's danger.
