I don' understand why people think that anyone can show that masks may have worked.
1. We have data with which shows masks did not protect those who wore them vs those who did not..
2. With respect to protecting others...
We just don't have the ability to separate out...
what a mask may have done... vs distancing... vs immunity vs the season.
