Here’s a study that did just that, reported in Dec 2020:

And here’s a summary of probable ivermectin actions as an anti-viral: https://www.ncbi.nlm.nih.gov/labs/pmc/articles/PMC8688140/
I might remind that even fauxi was an author on a paper published in or just after the first decade of this century that found anti-viral action by ivermectin. Of course, since he’s a big Hillary fan-boi, he could always claim he doesn’t recall or remember or at this point, what difference does it make.
“The trial included 72 hospitalized patients in Dhaka, Bangladesh, who were assigned to one of three groups: oral ivermectin alone (12 mg once daily for 5 days), oral ivermectin in combination with doxycycline (12 mg ivermectin single dose and 200 mg doxycycline on day 1, followed by 100 mg every 12 h for the next 4 days), and a placebo control group. Clinical symptoms of fever, cough, and sore throat were comparable among the three groups.”
So this says that ivermectin did not have a significant effect on people with Covid.
