It didn’t work in most of Africa... The only continent not affected, and that was likely because most countries (other than South Africa) didn’t lock down. Hmm!
Another thing about Africa, particularly sub-Saharan Africa, is they have a lot of malaria, a primarily tropical disease, and consume huge quantities of hydroxychloroquine to treat it. Thus, they were inadvertently using one of the best treatments for COVID that exists. Of course, for some strange reason, Doktor Fauchi and the rest of the medical establishment somehow managed to ignore all of this.
