re: What purposes does the vaccine serve for people that have beaten covid?

My recent story is interesting. Went to get a rapid Covid test a week and a half ago because I had last minute plans for dinner in the city. Just wanted to get negative test since I’m not vaccinated and do not intend to get the vaccine. Take the test, the doctor comes in and asks me if I’ve been exposed to anyone with Covid. I respond not that I’m aware of. He says why are you tested positive for Covid.

Then he proceeds to say that clearly I don’t have it, all vitals are perfectly normal and suggested he orders an antibody test. Goes on to complain about how terrible the rapid tests are. I had Covid back in December and my only symptom was that I lost my taste and smell for a few days. So I said sure, I’d be interested to see if I have any antibodies left. Got my results back yesterday and no antibodies.

So I guess, now I’m wondering if I did have COVID or not. Not that it matters, still not getting the vaccine.
