I read an interesting argument for what might’ve been going with the handful of studies that found a correlation between the two (excising the ones that were clearly problematic or bullshit). All of those just happened to be done in places that have elevated levels of parasitic infections. So argument was, what was most likely going on there was the ivermectin was treating underlying parasitic infections which improved symptoms, not that it did anything against Covid. Which is why all the studies done where parasites aren’t so endemic found no correlation.
