Actually, ozone was tested in HIV+ patients

Actually, ozone WAS tested in HIV patients many years ago:

(removing the blood, treating it with ozone, and returning it to the patients) – no effect. This is the abstract for the phase II trial. You’ll see it reported that in the uncontrolled phase I trial, a few patients appeared to show some improvement. There was also some in vitro work that suggested that ozone would help. This pattern (preliminary results suggesting a benefit, followed by more rigorous – and often longer-term – trials showing no benefit) is a common theme in research into new HIV treatments.
Anyone who has been alive with this virus for at least a couple decades remembers when there was a lot of interest in ozone for HIV. Most of the people I know who tried to cure their HIV with ozone are now dead.
