In the referenced Youtube video, Joe states he treated his Covid with:
"all kinds of meds. monoclonal antibodies, ivermectin, z pack, prednisone, everything…"

Monoclonal antibodies have been authorized by the FDA to treat Covid-19. The FDA authorized the use of this treatment because it works and it's safe. The monoclonal antibody treatment is likely what helped Joe recover so quickly.

Ivermectin likely deserves no credit for Joe's recovery. It's like getting bit by a rattlesnake and immediately treating the venom with anti-venom, a handful of Skittles and penicillin - and crediting the Skittles for saving your life.
