In an interesting study I read about in Nature, it seems that once your body has bumped into COVID of any variant, you are strongly resistant to catching that variant again but you become less resistant to other variants than you were before you had COVID. While sounding weird, this is because your immune system recognizes the virus as COVID and starts to rapidly produce the wrong version of antibodies. (Memory is this is called "imprinting".) It appears that is partially why we've never developed Herd Immunity, as we hoped. Obviously, this is because COVID, like many coronaviruses, mutates rapidly and for the same reason we don't develop Herd Immunity to the various versions of the common cold that are coronaviruses, we should not expect to develop Her Immunity to COVID.
Sigh....
What this probably means is that unless we have a different approach to COVID vaccines, they will work to kill off all the known versions of COVID, but will still leave us getting sick from one of the massive numbers of mutations floating around.
It appears that this is the most compelling reason it is so important to reduce the global number of people getting sick. Unlike smallpox, if this virus has even a small pool of people in which to mutate, it will mutate. Then we'll be faced with a new wave. Precisely what we're seeing now with so many people unvaccinated+boosted. (Only 35% of California folks are up to date on there boosters.) Given irrational resistance to vaccination and our unwillingness to get the rest of the globe vaccinated, I fear we'll have to resign ourselves to catching some variant of COVID for the rest of our lives.
Sigh....
