Boston Mayor Marty Walsh received his first dose of the coronavirus vaccine last week.
His office confirmed the news to WBUR after it was first reported Thursday night by CommonWealth Magazine. His office did not provide any more information or answer other questions.
Walsh is President Biden's pick for labor secretary, though his confirmation hearing has not been scheduled yet. Several other nominees to Biden's cabinet also received the vaccine last week.
Walsh did not take questions at his Friday press conference instead turning reporters to Marty Martinez, his chief of health and human Services.
Gov. Charlie Baker has said that he does not plan to get vaccinated publicly or early to inspire public confidence in the vaccine. He said he'd leave that to public health officials.
The 64-year-old Baker has said that he plans to get his first dose in line with when he becomes eligible on the state rollout plan.
