Strange conclusion to draw. Ivermectin is an antiparasitic, doses much higher than the maximum approved or safely achievable for use in humans would be required for an antiviral effect. Joe never provided any evidence for his claims, and the studies have been problematic to say the least. [1]

So he remains completely wrong, as usual. This single study from "Cureus" seems to correlate that treating your parasites with an antiparasitic could help you recover from COVID in one specific part of the world though.

No, he was not right. The correct interpretation is, "where parasite infections are endemic, treat that and your health will benefit." And, wear your mask.

Why would they apologise ?

People were literally taking the horse de-wormer formulations because they couldn't buy it legally.

Pre-infection prophylaxis is not the same as treatment for infection. That's where a large number of people had things wrong.
