Hey, you're vaccinated right? Svetikd/Getty Images Pucker up: The CDC says you can regularly flash your face at strangers if you're vaccinated. In a major shift, the Centers for Disease Control and Prevention announced today that fully vaccinated Americans can go maskless and give up physical distancing in a majority of cases, both indoors and outdoors. In some places, like airplanes and health care settings, masks may continue to be required. Obviously, the key phrase here is fully vaccinated, and guidelines differ between states. The rule is now simple: get vaccinated or wear a mask until you do. The choice is yours.
