Immunity and resistance are the same thing, not two separate things. Total immunity ("sterilizing immunity") is relatively unusual, and doesn't seem to exist for covid, but covid immunity seems to last for at least several months, maybe a year or more, at high enough levels to prevent epidemics ("herd immunity"). Given how fast O spreads, it seems likely that it will burn itself out among the humans in a few months --- but covid will probably always be able to come back from the zoonotic reservoirs.

I hope you're right about the scariness, but I worry about the incidence of "long covid", and in particular the possibility of widespread organ damage from blood clots.
