No, most of what you said is wrong. The history of ivermectin: Merck began marketing ivermectin as a veterinary antiparasitic in 1981.[7] By 1986, ivermectin was registered for use in 46 countries and was administered massively to cattle, sheep and other animals.[82] By the late 1980s, ivermectin was the bestselling veterinary medicine in the world.[7] Following its blockbuster success as a veterinary antiparasitic, another Merck scientist, Mohamed Aziz, collaborated with the World Health Organization to test the safety and efficacy of ivermectin against onchocerciasis in humans. Ivermectin is an animal drug that was then used in humans for severe cases of parasitic infestation (i.e., lice, scabies, etc.). It is absolutely not a drug intended for normal human use.
