So I’ve never had a good immune system. Lots of allergies and usually get 4-5 colds a year ending in a sinus infection. I got the original strain of covid (although never “tested” positive) back in March 2020, which became long covid and took me months to recover from. My body has never been the same and I now have autoimmune issues. BUT - I haven’t had a regular head cold in 2.5 years which is unheard of for me. Did covid make me immune to corona viruses? Lol. I don’t understand it. Colds all my life and then I get covid and no more colds. Weird.
