The flaw with these kinds of statements is that it assumes the 70% is uniformly distributed throughout a population. Obviously, if an entire town decides to avoid vaccination, it'll be vulnerable.

Reinfection and new variants surviving in networks like this imply COVID will be around for a very long time.
