But even if we knew natural infection prevented future infections in all (which it doesn't, people get double or triple infected), it still wouldn't make sense. (For if it leaves you open to reinfection, see spaced exposure, initial viral load, etc.) Because we don't have the records to corroborate everyone's claims they were infected. And, a lot of the people who would claim to have already been infected I have little trust in to be honest, let alone the difficulty of self-diagnosing.

There's no cost to getting the damn shot, so what's the fucking problem with requiring it?

You make an impassioned and personally attacking me case that natural immunity should exempt you, but why not get the vaccine?
