@GregoriTonon@LanceMcDougall1 @DeniseHiser @bennyjohnson I'm fully aware that vaccinated people can still get infected.
I singled out the unvaccinated people only because they, as compared to fully vaccinated people, are more likely to develop severe symptoms once infected by COVID.
@LanceMcDougall1 @DeniseHiser @bennyjohnson Despite the big holes in them, masks reduce the distance of droplets' travel in the air.
Wearing masks protects the Unvaccinated people. Even fully vaccinated people can still be carrying COVID and infect other unvaccinated people, who could get very sick.
@LanceMcDougall1 @DeniseHiser @bennyjohnson It's amazing how this misperception persists after we have been in the pandemic for so long.
Wearing a mask reduces the amount of droplets (which carry the virus particles) released when someone breathes/coughs/sneezes. Droplets are 10-20 times bigger than the viral particles.

Furthermore, a number of key economics such as median household income and CPI, are not accounted for in this study.
@chenweihua@merics_eu There is something called Selection Bias (in this case, caused by the issuance of Chinese visas to selected individuals):
