As I said to you before, you do you. If you want to swallow the stuff by the gallon, good for you and have at it. I wish you well. You read your studies - and I'm sure you will discount the ones tht don't support your ideas - and then post here about how right you are. It appearas you have an audience here.
As I have mentioned before, I take medical advice from my doctor, not the internet.
As far as Africa, I was not speaking only of COVID. Big Pharma has been testing new drugs and new treatments there for decades. Some work and some don't. Those that live in rural areas without much medical facilities - people with little education, are subject to companies without scruples, worldwide. So I suspect, although I don't have any facts to prove it. that is what has been done with COVID.
