ivermectin does have a place in medicine. Yes, perhaps millions of doses on ivermectin have been prescribed for tapeworm in humans. Any evidence of viral cure is because the ivermectin kills the parasite that is hosting the virus. As the parasite floods the body with virus created internally in the parasite and the body reacts with infection, it can appear to directly fight the virus when it kills the parasite.The medicine is ineffective when the human body is the host of the virus.
