I started taking Calcium + D3 many many years ago. I have not had a serious case of flu or cold since then. I did get the pneumonia shot and the shingles vax, but have NEVER had the flu shot.
I had a particularly nasty case of a variant of the Hong Kong Flu back in the early 70s/late 60s. Took forever to get over it, and for about 5 years was still hacking and coughing before my lungs went back to normal-caught every bug that came around during that time frame, which quickly became bronchitis.
I wonder if that might have some peptides in common with the RONA - hoping I would have some of that pre-existing immunity we hear about.
I still haven’t made it to CVS for my antibodies test but I really need to go. I also take D3 and Calcium plus others so right now I’m trying to decide if I really want to take a chance with the flu shot or not. I have never had any trouble with it before but this year is strange.
