Thank you Lord! these anti malarial drugs are CHEAP and easy to produce. We can make ALOT of it QUICK.
Used for DECADES, so even if you dust off a 30 year old medical book, even noob doctors will know about choroquine, quinine, and hydropchloroquinine.
Seventy year old medical books even.
The military was using it by the end of the forties.
We were still using it when I was in.
It can have pretty potent side effects and a lot of people got a fever or chills from it.
