A word about masking indoors from Ashish K. Jha

So, dear reader, if you're vaccinated and living in a state like Massachusetts where vaccination rates are high and infection rates are low, you may be wondering: Is dropping my mask risky behavior given the spread of the Delta variant? (I know I've been wondering that....) In an opinion piece for the Globe today, Ashish K. Jha, dean of Brown University School of Public Health, wrote that vaccinated people in highly vaccinated communities can likely skip the mask. But there's always some risk. Here's a great metaphor from Jha:

"Being fully vaccinated is like getting a great hockey goalie (think of Boston Bruin legend Gerry Cheevers) who blocks around 90 percent of attempts. In Massachusetts, there isn’t much virus around to even put a shot on target, and therefore little reason to wear a mask indoors. In Mississippi, there are simply many more shots on goal, and even a terrific goalie will occasionally let a shot in."
