On May 13, 2021, the CDC announced it was updating its mask wearing guidelines for fully vaccinated people. Here is a link to the CDC guidelines  https://www.cdc.gov/coronavirus/2019-ncov/vaccines/fully-vaccinated.html.  The PA Department of Health Order states it will follow the CDC guidelines so, effective immediately, employees and customers who are fully vaccinated are no longer required to wear masks. People who are not fully vaccinated must continue to wear masks until further notice. As a business owner, you may still require customers and/or employees to wear masks, even those who are fully vaccinated, but you should make your policy known by posting signage near your front entrance.
