I read Scott’s piece the day it was published and was over all impressed but don’t buy the conclusion. Westerners are filled with all sorts of parasites and as far as I’m aware we are not universally cleaner in that regard, for example with worms, than other places. That to me suggests that to the extent a significant fraction of the population would benefit from deworming, ivermectin’s widespread use in some of our hospitals during the pandemic was not entirely illfounded and may have even played a part in more than one life saving treatment regimen.
So I would love evidence that says clearly why it doesn’t work here but works in poorer places because somehow Americans are too good for parasites. My experience tells me this is wrong, and many Americans are carrying all sorts of bugs. Go read the Amazon reviews for proguard!
