Here is some actual very good advice on optimizing immunity. I personally would not consider the highly experimental “vaccine” for this generally mild, non-fatal, and perhaps mostly in-the-past disease; but I will sure follow this simple advice for life to have great immunity against all infections. It is sad that our governments are crushing our economies and culture with lockdowns and burying us in debt for radical and expensive measures and injections, rather than help us at all with simple good advice like this. Enjoy and live this information.
