    iirc it’s also only helpful if you’re already deficient in vitamin A, which the majority of Americans aren’t. It’s the same thing with Ivermectin: it looked like it was helpful for covid in aggregate, but only in developing countries where parasites are common. So, treating someone’s parasites with a horse dewormer made the person healthier overall and meant their immune system could commit more resources to fighting covid, but someone without parasites (meaning the majority of Americans) would get absolutely no benefit.
