makes me wonder if repeated exposure that doesn't result in the virus replicating enough to take hold in the body gives you any kind of immunity, or if that is even a possibility. like how many viral bodies does it take, just 1?

It absolutely does. An very low dose initial infection can prime the immune system and give you an asymptomatic case.

...but even if you full blown covid, there is no exemption from the vaccine requirement - that's one of the main arguments of many health workers.
