“a prominent French researcher.” How much in his bank account NOW?
No, you are wrong! Professor Raoult did not make any money on HCQ. Actually that is probably one of the problems with this drug. The patent has lapsed and it is too cheap to make big profits.
Professeur Raoult and co-workers probably saved hundreds of lives in the region of Marseille in south-eastern France using HCQ+AZ (and later on Zn) in early Covid-19.
