That means your claim that it “only works in vitro” is false, though. The right claim would be “we don’t know yet”. Also you do a lot of work to make it sound

That means your claim that it “only works in vitro” is false, though. The right claim would be “we don’t know yet”. Also you do a lot of work to make it sound like a foregone conclusion it doesn’t work (appeals to authority in “anyone paying attention”). The problem is there is now a lot of anecdotal evidence of it working from good sources (teams of doctors on frontlines from around the world). So really you can’t appeal to anyone paying attention.
