Earlier quoted context omitted.
Because the risk of transmission is understood to be significantly lower, and since unvaccinated people are more likely to cause the virus to mutate it's in the governments best interest to get people vaccinated, a way of accomplishing this could be making life inconvenient for the uncompliant.
> unvaccinated people are more likely to cause the virus to mutate Maybe I'm missing something, but the vaccinated population is the one that has introduced an additional evolutionary pressure, so wouldn't we expect to see mutations (that affect vaccinated people) in that population? Vaccine tolerance is no advantage in unvaccinated hosts.
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.
