The problem with ivermectin wasn't safety, but efficacy. If you have worms, ivermectin is great for you! Take it!
All the studies that showed ivermectin's effectiveness against Covid happened to be from countries with low levels of sanitation. The kinds of places where people are likely to suffer from worms without knowing it. If you have worms and Covid, and take deworming medicine, guess what? You're more likely to beat the 'rona. It doesn't mean the ivermectin cured you of Covid.
