According to the CDC, most fully vaccinated people do not have to wear a facemask if the spread of COVID-19 in their community is low. If there is a medium level of COVID-19 spread in your community, you should talk to your doctor about wearing a mask indoors in public, especially if you’re immunocompromised or at high risk of severe illness. If there is a high level of COVID-19 spread in your community, you should wear a mask indoors in public, even if you’re fully vaccinated. When choosing activities, you should keep in mind the number of people participating, the location, and how COVID-19 is spreading in the community. In general, outdoor or well-ventilated gatherings with fewer people are better. Fully vaccinated people should continue to wear a mask in health care settings and where required by law or regulation, including business and workplace guidances. At UPMC, we are still requiring all visitors to our facilities, including hospitals and ambulatory locations, to wear a mask, even if they are fully vaccinated. The CDC also recommends wearing a mask during travel (airplanes, trains, buses, etc.) and while in transportation hubs like airports, bus depots, and train stations. Vaccination does not guarantee that you will not get sick from COVID-19 or be contagious to others if you are exposed to the virus. If you start to experience COVID-19 symptoms, you should quarantine and call your doctor about getting tested for COVID-19 — even if you have been vaccinated. Also, if you are immunocompromised — from a medical condition like cancer, HIV, diabetes, or transplant or from certain medical treatments — talk to your doctor. People with compromised immune systems are less likely to have a good immune response to the vaccine and may remain vulnerable to COVID-19, even after vaccination. If you or a loved one is immunocompromised, you may still need to practice preventive efforts like mask-wearing even after vaccination.
