Mandatory NIH Visitor Vaccination Attestation Begins January 18

In accordance with COVID-19 Screening Guidance for HHS Facilities, effective Tuesday, January 18, 2022, all non-patient visitors arriving to an NIH facility will be required to attest to their vaccination status. If they attest they are not fully vaccinated, visitors must provide proof of a negative COVID-19 test result within the last 72 hours to gain access to the NIH main campus, NIH-owned facilities and certain leased locations which are staffed with NIH security guards. Accepted vaccines are those approved or authorized by the U.S. Food and Drug Administration (Pfizer, Janssen/Johnson & Johnson, and Moderna), those approved by the World Health Organization, or a full vaccine series (not a placebo) in a clinical trial (e.g., Novavax). This policy excludes NIH Clinical Center patients and caregivers.

Please note: Actual enforcement begins on Monday, January 24. Although visitors will be asked to attest to their vaccination status beginning on January 18, actual enforcement will not begin until Monday, January 24. This allows for a period of transition and no visitor will be turned away solely on their attestation response or lack of a negative COVID test result until January 24.

Q: Why is the COVID-19 Visitor Vaccination Attestation being required at NIH?

A: By virtue of Executive Order (EO) 14042, “Ensuring Adequate COVID Safety Protocols for Federal Contractors” (, the Department of Health and Human Services (HHS) is implementing these screening safeguards to decrease the spread of COVID-19. Please note, this policy excludes NIH Clinical Center patients and patient caregivers.

Q: As part of the Visitor Vaccination Attestation, what is required to gain entry to NIH?

A: Each visitor will be required to attest to their vaccination status at an NIH security checkpoint indicating whether they are:

  • Fully vaccinated (no booster required), or
  • Not yet fully vaccinated, unvaccinated, or
  • Declining to provide vaccination status

Q: What happens if a visitor does not attest to their vaccination status?

A: After a one-week transition period of notification beginning on January 18 (enforcement begins on January 24), those visitors arriving without a vaccination attestation or negative COVID-19 test result will not be allowed entry to NIH. Those who do not attest to being fully vaccinated (no booster required), must show results from a negative COVID test taken within the last 72 hours. This test result cannot be an at-home test. It must come from a licensed medical facility (PCR or rapid tests are acceptable) with the visitor's name included on the result. Digital copies of COVID-19 test results are acceptable. Attestation comes with a potential penalty for providing false information. Please note, this policy excludes NIH Clinical Center patients and caregivers.

Q: What will NIH Security do with the Attestation or Negative COVID-19 Test Result?

A: No information related to a visitor's vaccination status or a COVID-19 test result will be collected or stored.

Q: Does an attestation or negative test result need to be completed each time a visitor returns to NIH?

A: Yes. Any time a visitor leaves an NIH facility and returns, it is deemed a new visit.

Q: Who do I contact if I have questions about the COVID-19 Visitor Vaccination Attestation or Test Results?

A: Please reach out to the ORS Information Line at or call 301-594-6677 with any questions.
