More than 70% of Japan's population has received the COVID-19 vaccines, and the government is moving ahead with a booster shot in December. But a conservative radio host in the U.S. falsely claimed, "Japan drops vax rollout, goes to Ivermectin." Japan hasn't stopped its vaccine program and hasn't approved ivermectin as a COVID-19 treatment.
Merck and Pfizer are each developing a new oral antiviral drug that might prevent or treat COVID-19. The pills are very different from the antiparasitic medication ivermectin, contrary to claims online that they are “suspiciously similar” or that the companies are “repackaging” ivermectin in a ploy to increase profits.
The Food and Drug Administration says male infertility is not a known side effect of the antiparasitic medication ivermectin. Dubious claims that the drug sterilizes 85% of male users were incorrectly attributed to a questionable 2011 study of the drug's effect on a small sample of Nigerian men with onchocerciasis, a tropical disease also known as "river blindness."
