What’s more dangerous than to dismiss mask wearing os to overstate the effectiveness of wearing masks in protecting against Covid. Although there are many studies that seam to suggest that mask wearimg may be somewhat effective, it is very difficult to properly conduct a controlled study in a real world environment. We also have to keep in mind that mask wearing has become a political issue, and any study questioning the eefects of masking would likely not see the light of day. There os a shul in my community that requires mask wearing as all the shuls in my community do, that had a very large outbreak. I cannot help but think about all the high risk individuals that attended that shul armed with the quote from the CDC director “Masking is more effective than a vaccine”. Then there is this tidbit buried on the CDC’s website.
“Neither surgical mask can effectively remove submicrometer sized aerosol particles such as aerosolized bloodborne pathogens”
