Reply to comment by BurrDurrMurrDurr in New evidence suggests that ‘hybrid’ immunity, the result of both vaccination and a bout of COVID-19, can provide partial protection against reinfection for at least eight months. Immunity acquired by booster vaccination alone seems to fade somewhat faster. by MistWeaver80

Mutation matters, but some rapidly mutating viruses like rabies are easy to immunize for long periods while some slowly mutating viruses are hard.

I have friends who keep asking why we don’t just make all vaccines last for a really long time. I always point out that if you could actually figure out how to do that, you’d win the Nobel prize tomorrow. Also worth noting that there was serious discussion of quarterly vaccines for flu prior to COVID(primarily for at-risk)
