If "they " were truly concerned about the health of a nation they would be advocating Vit D etc. instead of experimental; "vaccines" I did a recent search on Vit D. Articles prior to 2020 were laudatory and clearly advocating higher doses of Vit D for better protection against flu and overall immune health. Mar 2020.... Vit D was regulated to the dust heap along with some many other PH measures of the past 100 plus year.

I was exposed several times to Covid this summer and never got it. Did not develop antibodies either. Not sure if that was because the exposure was not high enough or my immune system just did not let the virus in?
