IIRC my biology lessons in high school, viruses mutate in order to escape from vaccines. Just like mosquitoes mutate and adapted to DDT, we created new chemicals and then mosquitoes adapted to them, under evolutionary pressure.

So vaccinated populations are creating the pressure on the virus to mutate. And un-vaccinated population may get effected (irrespective of which version of virus they encounter at the time)..

my 2 cents.

Viruses don't mutate to escape anything, evolution doesn't work that way. Viruses have short generation times and they replicate extraordinarily fast compared to what humans see in their lifetimes. Their fast replication allows the virus to experience mutations at a massive scale and mutations that increase its survival become dominent over time.

Those mutations absolutely require an unvaccinated population to thrive but more importantly, a population with a laissez fair attitude that allows the mutation to spread to other humans. If you do everything in your power to cut down the transmission and vaccinate yourself, we could have defeated this thing.

But nope.. and here we are.
