General Dosing Information

  • There is no data available on the interchangeability of the Pfizer-BioNTech COVID-19 vaccine with other COVID-19 vaccines to complete the vaccination series. Patients who receive the first dose of Pfizer-BioNTech COVID-19 vaccine should receive a second dose of Pfizer-BioNTech COVID-19 vaccine to complete the vaccination series.

  • There is no available information on coadministration of the Pfizer-BioNTech COVID-19 vaccine with other vaccines. During clinical trials, the Pfizer-BioNTech COVID-19 vaccine protocol allowed influenza vaccines to be administered at least 14 days before or after the COVID-19 vaccine doses.[66160]

Advisory Committee on Immunization Practices (ACIP) Interim Recommendations for Vaccine Allocation (Phase 1a)

  • In the initial phase of the vaccination program, it is recommended that both health care personnel and residents of long-term care facilities (LTCFs) are the first to be offered the COVID-19 vaccine.

  • Health care personnel are defined as paid and unpaid persons serving in health care settings who have the potential for direct or indirect exposure to patients or infectious materials.

  • Residents of LTCFs are defined as adults who reside in facilities providing services, including medical and personal care, to those who are not able to live independently.

  • Priority may be given to health care personnel who work in close proximity (within 6 feet) to other people.

  • Priority may also be given to residents and health care personnel in skilled nursing facilities due to high medical acuity and COVID-19-associated mortality among residents in these settings.[66165]
