While ivermectin has not been approved as a drug against viruses, it is known to be effective in the lab against a broad range of viruses including HIV, Dengue and Influenza.
The experiments used high concentrations of ivermectin, notes Proff Campbell: “the concentration of drug needed to kill the virus in the lab was many times higher than the concentration of ivermectin found in the blood of people in the normal use of ivermectin to control parasitic disease.
“So the probability of ivermectin being used safely to kill the virus in people must be considered low,” he says.
“On the other hand, there is, as the authors of the report point out, the possibility that a safe dosage of ivermectin might reduce the rate of viral replication in the mammalian body, or affect the virus in other ways that might be revealed by further research. That is a more positive prospect.”
This is from 2020 btw.
