Yeah this is sort of true on it's face, but doesn't really change anything. Of course if a virus is widely spread it's more likely to have vaccine escaping variants out there. If you vaccinate that population those vaccine escaping variants become dominant. Obviously this is less likely in a population with less cases. But you have to vaccinate that high case population eventually and the sooner you do it the better. No sense giving the virus more time to mutate.
