"Large pro-ivermectin Facebook groups have turned into forums for people to find advice on where to buy it, including preparations meant for animals.
Some groups regularly contain posts about conspiracy theories of ivermectin cover-ups, as well as pushing anti-vaccine sentiment or encouraging patients to leave hospital if they aren’t getting the drug.
These channels have co-ordinated harassment of doctors who fail to prescribe ivermectin and abuse has been aimed at scientists. Prof Andrew Hill, from the University of Liverpool, wrote an influential positive review of ivermectin, originally saying the world should “get prepared, get supplies, get ready to approve [the drug]”.
Now he says the studies don’t stand up to scrutiny - but after he changed his view, based on new evidence emerging, he received vicious abuse."
