The emergence and spread of the Delta — and Delta plus — variants of Covid-19 have many governors and public officials across the country taking another look at their mask-wearing guidelines and restrictions. Massachusetts is no different.

A couple weeks ago, Massachusetts Governor Charlie Baker announced new tightened mask-wearing guidelines following a spike in positive cases, with Revere and Brockton both seeing severe increases.

The latest update recommends fully vaccinated people in Massachusetts wear face masks in public and indoor settings under certain conditions — but do not mandate them.

The guidance also recommends that “a fully vaccinated person wear a mask or face covering when indoors (and not in your own home)” if they, or one of their housemates, has a weakened immune system or is otherwise vulnerable or unvaccinated.

As travel resumes, please continue to be careful, and take care of yourself and others. We look forward to taking you to and from your next trip, comfortably and safely.
