Technically the Chinese Wuhan Institute was first to recommended hydroxychloroquine as a possible solution (among at least one other drug) months before this guy and the politicians ever published anything about it. There was also a small town US doctor who claimed anecdotal success among his hundreds of clients who was highly influential very early on. And tons of other speculative ‘experts’ talking about it on YouT…
Thia still puzzles me, presumably he understands things like placebo effect and double-blind studies intuitively, and yet studies show no improvement.
On a similar note, the WHO recommendation against the use of Remdesivir is widely criticised by doctors in Poland, as based on a poorly-thought-through study. The claim is that Remdesivir helps patients only at certain stages of the disease, whereas the WHO study doesn't differentiate between such stages.
On the one hand, there's people who use the drug day-in-day-out, on the other a huge organisation which I'd think can do good-quality science. I remain confused.
