The problem is that Ivermectin is off patent, so no drug company can make any money from it. Since there is no money for expensive research studies or clinical trials, all the research studies that get done will be low budget and subject to being called "lousy science". How about just properly reporting and studying the actual facts from one of the very large real world trials, like the one in India?
And why is Covid not really a thing in subsaharan Africa where everyone takes ivermectin anyway, because it’s a marvelous antiparasitic drug. You’d think the poorest parts of Africa with the worst medical systems in the world would be hit harder, but they’re not. And it’s probably not genetic since the African diaspora is hit hard by covid.
My surface-level, limited perception in a couple countries I have friends/family in (Cameroon, Kenya, Nigeria) is that there's little to no testing, but also not apparently a hospital emergency. Then again, these same people also seem to go to their local hospital for what is understood as typhoid and malaria every year or two at least. As a born and raised North American I get told by them that's normal.
