It is the one treatment that is cheap, already manufactured in large scale, and not in control of any single entity. Of course people are rooting for it.
People who need it for medical conditions are finding it impossible to find. Not sure how large the production is.
Any treatment that is found to actually be effective in real studies is pretty clearly going to be nationalized, recreated by countries around the globe, and mass produced overnight.
It's large, or can be easily scaled up. Novartis is pledging 130M tablets, Teva 16M, Mylan is planning on ramping production up to 50M.
