"Vaccines save lives. With this unprecedented pandemic continuing to rage, I am deeply grateful for the scientists, researchers, and frontline healthcare workers who have worked tirelessly to develop vaccines that are safe and effective, and ensure that our communities are protected," Pressley added in her statement.

The Massachusetts Democrat has been a supporter of mask and vaccine mandates, and called on Republican Massachusetts Gov. Charlie Baker to reinstate an indoor mask mandate in the state on Dec. 21. She said Baker’s advisory that residents wear masks while indoors "falls well short."
