My favorite example being germ theory [1]. Granted, he went over the top (claiming all infant mortality was from cadaverous particles) a bit like some who claim Covid was a lab-leak from a Chinese bio-weapon; if you just stop at the lab-leak part you have a decent claim, the bio-weapon is what tanks your argument. But it's not like doctors started washing their hands despite his evidence of mortality dropping from 18% to 2%.
