There are people buying ivermectin from vet clinics if the doctors won't prescribe it. My understanding is that it works on most viral infections. As you know Joe Rogan used it. CNN called it horse dewormer which it is, but it has other uses. India has had success with it. The frontline doctors are using it. More money in the vaccinés though. I do agree eating good taking vitamins, excersise and prayer are essential.
