Twenty-one legislators have called on Republican Gov. Charlie Baker to halt his “younger companion” vacination, which allows anyone who accompanies a person age 75 or older to a mass vaccination site to get a shot as well. In a letter, lawmakers argued the policy "will put thousands of healthy adults ahead of those who have the most significant risk of getting and dying from COVID-19." State Reps. Tami Gouveia, D-Acton, and Tram Nguyen, D-Andover, joined Jim Braude to explain.
