The thing that really gets me is the medical professions reluctance to use Ozone. Specifically
1. Medical Ozone gas when on a ventilator (0.5ppm of Ozone added to O2)
2. Ozone Therapy.
Medical Ozone
Ozone gas damages lung tissue at or above 1ppm but it is deadly toxic to Coronavirus. Indeed Germany and Eastern European countries used it in the 1950s and 1960s to fight viral pnumonia and it has a track record of slowing viral pneumonia and allowing the body to fight it. Many older German doctors still use it and this may be part of the lower German death rate.

Ozone Therapy
Then there is Ozone Therepy that has been used to boost the imune system for 50 years. Amongst other things it is pretty much the only cure for Lyme disease.

The reason of course is that drug companies can't make money out of Ozone.
