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.

The NIH headquarters, known as the “NIH campus” to the local community, are located in Bethesda, Maryland. Administrative and program operations facilities are also located in off-campus buildings in the surrounding area. NIH scientists conduct their research in laboratories located on the main campus, and in several field units across the country and abroad.
