As advised, I looked at 4 top papers at FLCCC site ivermectin section:
1 study: shows 75% improvement use in prophylactics reducing viral load in young people in Dominican Republic. Authors explicitly say that this is a tool in addition to vaccination.
2nd: study is withdrawn by the referred journal
3rd: Israeli preprint similar to (1) on a small sample, results claim 3x improvement, but plot over time shows less improvement with a jump up on the last day, others have questions about study design
4th: a meta-review describing
– multiple trials, some showing 3x or no improvement in PCR with lower death rates on small samples.
– comparison of pairs of towns in South America – same idea as Bangladesh study, but without proper design. There is no way to check whether towns are comparable, etc. Claimed results are similar to mask wearing: 2x reduction rates.
Many of the results above are pre-Delta
Overall, this conforms to my impression: this is a hopeful tool, especially in poor countries, but even
most optimistic claimed results say that this is another layer in defense, in now way a substitute for vaccines, masks, etc – and some of the authors say exactly same thing.
