Every wackjob here was saying ppl would die from heart attacks or cancer after getting the jab, so I know this is widely circulated within Magasphere. People were even posting random stories of someone dying, and without no proof, imply it was from the vaccine. They're still doing it. Ditto for nuclear war with Russia.
Surgical and especially N95 masks were highly effectively up until omicron. Surgical masks stopped being effective because omicron was simply too contagious, but N95s were still good.
