Fully vaccinated people don’t need to wear a mask or physically distance during outdoor or indoor activities, large or small, federal health officials said, the fullest easing of pandemic recommendations so far.

The fully vaccinated should continue to wear a mask while traveling by plane, bus or train, and the guidance doesn’t apply in certain places like hospitals, nursing homes and prisons, the U.S. Centers for Disease Control and Prevention said Thursday.

The agency said it was making the revisions based on the latest science indicating that being fully vaccinated cuts the risk of getting infected and spreading the virus to others, in addition to preventing severe disease and death.
