When the COVID-19 Community Level is medium or high, all non-patient visitors to NIH facilities will be asked to provide information about their COVID-19 vaccination status. If visitors are not fully vaccinated or decline to answer about their vaccination status, they will be required to show a negative COVID-19 test result from within the previous 72 hours. See the NIH Safety Plan for more information.
