“Don’t we have a lot of other inexpensive drugs that fight malaria?”
Yes we do and they are not something you want to take on a regular basis. The bubble guts is always present. Malaria is a pox on humans if someone comes up with an effective vaccine that will improve the lives of 4 billion. Having spent much time in the malarial latitudes not having to take high power antimalarial drugs with all that nasty side effects would be a blessing. Stop thinking every vaccine is some conspiracy. Those of use with WHO yellow cards who actually travel to real.hot zones.don’t want to hear boomer tinfoul stuff.
Yes, and no. Some work with some types of malaria and not with others. Each have amazing side effects. Then, after a period time, a strain of malaria in an area may become resistant to the drug of choice and a switch has to made if another is available.
FWIW, never, ever, ever take Larium - melifloquin. It has long-lasting psychotic side effects. It may work against malaria but it might kill you.
