So they say. That’s the whole point. The NIH says that ivermectin taken in a 5 day regimen may reduce the duration of covid.
If you look at Africa, which has a very low vaccination rate, single digit percentage, yet does not have the cases or deaths that Europe has. Why? Well hydroxy chloroquine is in widespread daily use as an anti malaria drug. Coincidence? Early in the pandemic there were doctors who said there was evidence that HC had a prophylactic effect against Covid, but of course the MSM came out screaming against it. Even though the drug is still being used today for it.
And finally, HC has been used to treat Lupus for decades. I know a man whose wife has Lupus and takes HC daily. Her whole family came down with Covid, except her.
