There seem to be plausible evidence Ivermectin works both to prevent Covid and treat in early stages : see, eg this meta-analysis of clinical trials by Andrew Hill : https://academic.oup.com/ofid/advance-article/doi/10.1093/of...
The human story from doctors in the field is compelling viewing : see testimony by Dr Pierre Kory, discussion of treatment by Dr Jackie Stone in Zimbabwe etc ..
The picture is cloudy - some plausible trials show neutral or no results, some trials show stunning effectiveness.
One thing many studies dont report is the way in which Ivermectin was given - taken with fatty food, the uptake is 2.5x compared with taken on an empty stomach. This and wide range of dosages could potentially explain why we see such extreme differences in trial outcomes ?
It does not help people come to a real understanding when a) right wing anti-vaxxers and conspiracy theorists promote Ivermectin in the same breath as other herbal remedies and b) youtube and mainstream media ban and censor much discussion of Ivermectin.
The original Monash in-vitro study is interesting - if Ivermectin truly is a broad-spectrum anti-VIRAL, thats a discovery on the order of Penicillin, with vast implications for medicine and human health.. beyond covid.
