CDC changes mask rules for fully vaccinated people using public transportation

Masks are no longer necessary in outdoor waiting areas or open-air seating for fully vaccinated people who use public transportation, the U.S. Centers for Disease Control and Prevention says.

The agency said the new policy applies to "airplanes, trains, subways, buses, taxis, ride-shares, maritime transportation, trolleys, and cable cars."

"While those who are fully vaccinated may resume many activities without wearing a mask, the travel environment presents a unique set of circumstances based on the number and close interaction of travelers (both vaccinated and unvaccinated)," the CDC said.

People who are not yet vaccinated should continue wearing masks in these areas, according to the CDC. It said both vaccinated and unvaccinated people should still wear masks indoors in public transportation settings, except in certain circumstances such as when eating, drinking, or taking medicine.
