At most, it's good information to have for those particularly vulnerable to COVID. Depending on one's vulnerability profile, N95 masks, or masks of any kind, can be wasteful and even harmful to the environment. For myself, my chance of getting seriously ill or death from COVID-19 is effectively 0%. SARS-CoV-2 is endemic, and I've had it twice, so I'm not gonna keep forking over my money for masks, especially N95s. But yeah, if we didn't have sufficient research on the effectiveness on masks by now, then the medical establishment has failed at its job. The CDC is supposed to control diseases, and yet masks were somehow a mystery decades after their inception? Wow. Why exactly should anyone have faith in these people?
