When I thought I was coming down with covid I used a nasal rinse with diluted hydrogen peroxide and iodine. For the same reason, to kill the covid in my nasal passages before it replicated and spread to my lungs.

The covid virus is relatively easy to kill. For some reason the powers that be just did not want to treat it early before it spread and replicated. Vaccination seemed to be the only thing they wanted to promote. FLCCC.NET has had early treatment protocols for a long time.
