Commonwealth of Massachusetts Updates Mask Advisory for Vaccinated and Unvaccinated Residents
Effective December 21, 2021: In response to the spread of the Delta variant and the emerging Omicron variant, the Department of Public Health now advises that all residents, regardless of vaccination status, wear a mask or face covering when indoors (and not in your own home). The DPH particularly urges this recommendation if you have a weakened immune system, or if you are at increased risk for severe disease because of your age or an underlying medical condition, or if someone in your household has a weakened immune system, is at increased risk for severe disease, or is unvaccinated.
