"Large, peer-reviewed research study proves ivermectin works", FLCCC Alliance on Substack (20 January 2022)

"Proves" is their word, not mine. I am not a medical person, so I can't judge the matter. What I will say though is that I rarely use the word "proof" about anything. Maybe 2+2=4 is pretty safe (at least it is for me), but I generally prefer things like "highly likely" or "beyond reasonable doubt" and other bet-hedging phrases like that. But the FLCCC Alliance is made of sturdier stuff, and if they're prepared to say this study "proves" the case, well, that must mean they're hugely impressed. Which is good enough for me.
