For everyone who is saying "I have never had Covid and ...", given the high rate of asymptomatic spread - how do you know? Have you had a recent antibody test? Kinda fascinated to know.
Anecdotally: both of the times I had Covid, I tested negative for a couple of days with two different brands of rapid antigen tests until I had really overt symptoms (bad headache, raging sore throat, fever).
Certainly anecdotally you hear of people who tested for multiple days after they think they may have been exposed and only get a positive result after five days or something like that.
The boxed tests, the take-home ones. In particular, the ones available in the United States (I think other countries were using other rapid tests than the US).
I cannot find the link, but the rate was something ridiculous, way north of 50%. I take it with a grain of salt, I can't easily tell if it's just more propaganda from the covid-ain't-real people.
I have never gotten it or at least not to my knowledge. I would sure hope that there is a genetic or even T-Cell immunity that could snuff the virus out before it takes a foothold since it could lead to better vaccines/treatments. IMO I think we need to explore vaccines that can develop T-Cell immunity over B-Cells. Antibodies fade and may no longer work as well if the virus mutates, but T-Cells do not have this problem and can actually kill the virus as opposed to creating obstacles for the spread.
An antibody test isn't going to prove an old infection hasn't happened. I probably got it in early 2020 before testing was available. I had my first ever antibody test a couple of months ago for a hospitalization. It was, predictably, negative.
I don't put a huge amount of stock in much of the supposed science from June 2020. Also, as in my case, people definitely got mild symptoms of something, tested (if they could), got a negative result, and went on with life--when it's entirely possible they had it.
