Fully vaccinated 'can shed your mask' most places -U.S. CDC

"If you are fully vaccinated, you can start doing the things that you had stopped doing because of the pandemic." CDC Director Rochelle Walensky said.

The CDC also said fully vaccinated people will not need to physically distance in most places. The agency also hopes the guidance will prod more Americans to get vaccinated.

The revised guidance is a major step toward returning to pre-pandemic life, but the agency still recommends vaccinated people wear masks on planes and trains, and at airports, transit hubs, mass transit and in places like hospitals and doctor's offices.

The CDC said fully vaccinated people should still wear masks where required by federal, state, local, tribal or territorial laws, and abide by such rules and regulations, including from local businesses and workplace guidance.
