The Centers for Disease Control on Tuesday April 27, 2021 outlined new guidance on mask-wearing now that nearly 100 million people in the U.S. are fully vaccinated against COVID. It’s unclear what state and local public health officials who have issued mask mandates will do in response to the CDC’s action.

Here’s what the CDC says on its website that those who are fully vaccinated can start to do and should continue doing. The agency considers a person fully vaccinated two weeks after their second dose of the Pfizer or Moderna vaccines, which call for two doses, or two weeks after the Johnson & Johnson single-dose vaccine. Those who skipped a second dose or haven’t had two weeks pass after their final dose aren’t considered fully vaccinated.
