Оказалось, что cloth masks are completely useless so that Europeans are banning them in planеs and surgical masks are only ~10% effective (for unvaccinated people).

Интуитивно, мне кажется, что для вакцинированных установить статистически достоверный эффект хоть каких-то масок не удастся.

про Rand Paul'a и его youtube ban есть неплохая статья на ээээ ну reason например

Paul has a point. But in this case, his flat, categorical statements about cloth masks are stronger than the scientific literature supports, relying on a couple of cherry-picked studies with known limitations while ignoring countervailing evidence.

In a video responding to his YouTube suspension, Paul reiterates that "most of the masks that you get over the counter don't work" and "don't prevent infection." He argues that "saying cloth masks work when they don't actually risks lives," describing it as "potentially deadly misinformation." While N95 respirators are effective at preventing virus transmission, he says, "the other masks don't work."

Paul would have been on firm ground if he had said cloth masks offer less protection than N95 masks. But the claim that cloth masks "don't work," meaning they offer no protection at all, is inconsistent with multiple studies suggesting that they reduce the risk of infection, especially when worn by carriers but possibly also when worn by other people in their vicinity.

Paul cites two studies to back up his belief that cloth masks are ineffective: a 2015 study of health care workers in Vietnam and a 2021 Danish study that compared people who were advised to wear masks with people who weren't. Neither study proves that cloth masks "don't work."
