Why are some people seemingly immune to COVID?

[DrHenley]

COVID is not the only coronavirus people commonly get. Some cold viruses are also coronaviruses, and now it appears that T cell immunity aquired from a common cold coronavirus infection can provide some immunity to COVID!

My 89 yr old mom has been repeatedly exposed, at least four times in close contact, and she's not had covid. Husband says it's because she's too mean. He's right.

I think it is because, at least for me working daily in a public environment, I have been slowly exposed and built an immunity. I really do think I caught some sort of this virus a couple weeks ago with it just being sinus issues. Can't say that for a fact.

I felt I avoided it previously because of the protocols my wife put in place.
A couple of weeks ago, I posted a thread about having a cold and being negative. A few days after, I had a side effect where I couldn’t make it the 10 steps to the bathroom.
If that was it, then I had it. Other wise I haven't felt poorly in 2 years. I did a some research and I could get an antibody test at CVS if I really felt the need.
Only reason I would get the test is to exempt me from a booster.
