If you’re not already familiar with it, ivermectin is a wonderfully effective anti-parasitic medication that people thought might work against COVID-19. It’s very safe when given in the low doses needed to treat parasites, and extremely cheap, making people quite excited about its potential as a COVID-19 treatment.
