JULY 30, 2021.....Massachusetts public health officials on Friday began advising vaccinated people who live with any person at high-risk for COVID-19, who have weakened immune systems themselves and who are at an increased risk of severe COVID-19 because of their own age or health conditions to wear a mask or face covering when indoors and not in their own homes.

The shift in state suggestions comes as COVID-19 cases and hospitalizations are on the rise once again, this time propelled by the more contagious Delta variant, and on the heels of a new federal recommendation that even vaccinated people mask up in areas of significant coronavirus transmission.
