The vaccine hesitancy will impact vaccines for HPV, measles, HEP B, etc. etc. for generations.
This will be geographically--and, over time, economically--isolated.
Nearly 80% of American adults and over ¾ of eligible Americans have taken at least one dose of a Covid vaccine [1]. In the 65+ population, the figure is 95%. This simply isn't a big group of people, noisy as they may be. (Caveat: the group of people who are philosophically against vaccine mandates, but will get vaccinated anyway, is larger.)

We have experience containing outbreaks in small, isolated groups of high-risk populations. Even in densely populated places, e.g. measles in Williamsburg. The advantage is you know ex ante where the risk is, versus having the possibility of it popping up at random anywhere in the country.
