Sounds like you may have gotten the Regeneron antibody cocktail for your first bad case of Covid. Did you get a tranfusion? A close friend of my father's got the Regeneron antibodies after getting COVID (he was in his late 80s) and without it he would have likely passed away.
Glad to hear you won your battles with covid and your second bout with covid was not as bad. I also got sick from covid but I just got sick once. Never got a vaccine. Natural immunity has been proven by researchers to work better than vaccine-induced immunity in published studies. It makes sense because your body sees the whole virus with multiple antigens rather than just 1 antigen (spike protein) from the covid vaccine. It's sort of analogous to DCVax activating the immune system against multiple antigens instead of a peptide vaccine doing so against just 1 antigen. Cheers!
