The Yale Professor has been proven wrong. Three large randomized studies were stopped early, two because they had progressed to the point where we knew that they could not show that hydroxychloroquine does not help treat COVID-19, the other because they could not get enough people to participate in the study. Furthermore, even the decent observational studies, with only one exception, showed that hydroxychloroquine was not helpful.
The lockdowns have led to a spectacular drop in cases, hospitalizations, and deaths in New York. Ending lockdowns in Florida, Texas, and Arizona led to increases in all three.
There really isn’t anything to discuss here.
