After holding nine formal meetings since June and hearing more than 70 presentations on COVID-19 vaccine, on December 12 the Advisory Committee on Immunization Practices voted to recommend the use of the Pfizer-BioNTech COVID-19 vaccine for persons 16 years of age and older in the United States. This historic vote followed issuance of the Food and Drug Administration’s Emergency Use Authorization (EUA) for the vaccine on December 11 [see story above].
The ACIP recommendations and additional guidance for the vaccine’s use became official when adopted by CDC and published as ACIP’s Interim Recommendation for Use of Pfizer-BioNTech COVID-19 Vaccine—U.S, December 2020 in the Morbidity and Mortality Weekly Report (MMWR) Early Release issued on December 13.
While the MMWR publication should always be consulted for official guidance, additional highlights of ACIP’s clinical guidance discussed at the committee’s December 11–12 meeting are provided below:
- Administration – The Pfizer-BioNTech COVID-19 vaccine is administered intramuscularly as a 2-dose series separated by 21 days. Although the 21-day separation should be followed as closely as possible, the standard 4-day grace period (allowing a 17–20 day interval between doses) is acceptable. If more than 21 days elapse between doses, vaccine should be administered at the earliest opportunity, but doses do not need to be repeated due to a longer interval. Both doses are necessary for protection. COVID-19 vaccines are not interchangeable, and care should be taken to ensure the same vaccine is used for both doses. However, if different mRNA vaccines are inadvertently administered, no additional doses of either vaccine are recommended at this time. A minimum interval of 14 days should be maintained before or after administration of this COVID-19 vaccine with any other type of vaccine.
- Persons with a history of SARS-CoV-2 infection or exposure – Persons should be offered vaccine regardless of a prior history of infection. However, if they are currently infected, vaccination should be deferred until their recovery from acute illness. To avoid exposure to healthcare personnel, vaccination should be deferred for persons with a known SARS-CoV2 exposure until after their quarantine period has ended, with the exception of those who live in congregate settings (e.g., long-term care, correctional facilities, homeless shelters). Vaccination should be deferred for 90 days following receipt of monoclonal antibodies or convalescent plasma used as part of COVID-19 treatment.
- Special populations – Unless otherwise contraindicated, persons with underlying medical conditions or who are immunocompromised may receive COVID-19 vaccine. Pregnant or lactating women may choose to be vaccinated after discussion with their healthcare provider to assess their risk of infection, to make an informed decision. Routine testing for pregnancy before vaccination is not recommended.
- Patient vaccine counseling – All patients should be counseled about the importance of receiving both doses of vaccine, as well as expected local and systemic post-vaccination symptoms.
- Interpretation of SARS-CoV-2 test results in a vaccinated person – Prior receipt of vaccine will not affect results of viral tests. Vaccination could affect anti-spike antibody test results, but not antibody tests based on nucleocapsid.
ACIP also voted to add descriptive text and a link to current COVID-19 vaccine recommendations within the 2021 U.S. Adult and Child/Adolescent Immunization Schedules, which will be published in February.
