You know what I find…interesting? Places like Portland, are all about masks etc, yet, they are just fine, with fetid tent cities and bums camping all over the place. Funny how that works. From what I remember about history, fetid, scummy places, tended to be hot beds of disease, running over with rats, roaches and all those sort of creatures. Better get those masks on because they will protect you, but lets go ahead and ignore all those things history has proven to be REAL sources of problems. Waste, rodents, and filth.
How is an immunization supposed to work. Well, if never exposed to a pathogen, your body has not developed any anti-bodies for it, theoretically. So, an immunization, is a weakened or killed version of whatever it is you are trying to immunize against. It serves two purposes essentially, it is weak or killed, so your body can fight it easily, plus, it allows your body to figure out what it needs to produce the anti-bodies for that particular disease.
So, to your question. Theoretically, once you've been exposed to something, your body should be able to produce the anti-bodies needed to fight it off much faster. It seems to me, that if people are being, "reinfected," then either the vax ain't workin', or, somebody is spreading it around, as in variants. And if there are variants, then that means someone is probably PRODUCING them.
Context is everything.
