The use of ivermectin in humans to treat parasites won a Nobel Prize.
Quoting from the Wikipedia page:
"Half of the 2015 Nobel Prize in Physiology or Medicine was awarded jointly to Campbell and Ōmura for discovering avermectin, "the derivatives of which have radically lowered the incidence of river blindness and lymphatic filariasis, as well as showing efficacy against an expanding number of other parasitic diseases"
"There seems to be a growing interest in a drug called ivermectin to treat humans with COVID-19. Ivermectin is often used in the U.S. to treat or prevent parasites in animals.
The FDA has received multiple reports of patients who have required medical support and been hospitalized after self-medicating with ivermectin intended for horses."
