For one thing, hydroxychloroquine apparently has to be used with zinc.

For another thing, studies of Remdesivir, a drug that's closer to the heart (and wallets) of Big Pharma, has had way worse or very mediocre results.

For a third thing, years of research still haven't resulted in immunization for HIV, much less illnesses like the common cold.

I still trust people like Bill Gates. Just as I trust I can go to an ER room in Wuhan, China and lick the doors and floors without any worry.
