>Hmm, are you suggesting that those public policies might have had an impact on covid transmission that wasn't mediated through mask-wearing? That wasn't the intention of my comment, but yes that is also true. As the article notes: >"In the intervention villages, they also saw a slight increase in physical distancing in public spaces, such as marketplaces." My original comment was more directed at the fact that these public policies are not 100% effective in getting people to wear masks. Therefore the society reduction of 11% is not comparable to the vaccine efficacy numbers which are measured at an individual level. If we measured vaccine efficacy numbers using this societal approach, the numbers in the US would be abysmal considering our active case numbers are quickly approaching the peak of the pre-vaccine waves.
