Isn't this why there is a 1918-related flu outbreak every generation and why bubonic plauge used to recurved every generation because there aren't immune?

I think bubonic plague is bacterial, and was solved with antibiotics.

It doesn't matter that it's bacterial to have recurrences.

Also, we never "solved" the plauge, but it died down a lot before antibiotics were even a thing.
