> but the general population hasn't needed constant vaccination before. Uh, mass vaccination is 100% a thing https://en.wikipedia.org/wiki/MMR_vaccine https://en.wikipedia.org/wiki/MMR_vaccine https://en.wikipedia.org/wiki/Polio_vaccine# https://en.wikipedia.org/wiki/Polio_vaccine# I would say that we "Need" it. You could say that we don't, but it's vaccines or Polio outbreaks, so IMHO there's only one rational choice and it's not Polio. Yes, there are "vaccinate everyone" vaccines cited above. There are also "seasonal" vaccines for the flu. There has never been a need for a vaccine that is both of those. And once the disease is under control, it doesn't seem like covid-19 will be one.
