Pennsylvania will follow CDC's mask guidance for fully vaccinated residents WPVI Replay Video UP NEXT The Pennsylvania Health Department says it will follow the CDC's new recommendation to ease mask-wearing guidance for fully vaccinated people, allowing them to stop wearing masks outdoors in crowds and in most indoor settings. The health department is stressing that this only affects those that are fully vaccinated. "Today's guidance from the CDC affects only people who are fully vaccinated," Acting Secretary Beam said. "This is another incentive to get the vaccine that is now easily and conveniently available. Once 70 percent of Pennsylvanians over 18 are fully vaccinated, we can completely lift the masking order."
