Kathryn Dzintars, Pharm.D., BCPS

VACCINE TYPE

  • Effective April 19, 2023, the original monovalent Pfizer-BioNTech COVID-19 vaccine is no longer recommended; all doses to be given moving forward will be with the bivalent vaccine.
  • The Pfizer-BioNTech COVID-19 vaccine is a lipid nanoparticle-formulated, nucleoside-modified RNA (mRNA) vaccine encoding a prefusion-stabilized, membrane-anchored SARS-CoV-2 spike protein.
    • Primary series: Single dose, 0.3 mL
    • An additional bivalent vaccine dose for patients > 65 years of age or those who are immune compromised can be given at least 4 months after the previous bivalent dose.
  • Catch-up vaccination
    • Individuals who have received one dose of the monovalent vaccine: Two doses of the bivalent vaccine should be given 3 weeks after the first monovalent vaccine, with the second 8 weeks later.
    • Individuals who have received two doses of the monovalent vaccine: A single dose of the bivalent vaccine should be given at least 8 weeks after the second dose of the monovalent vaccine.
    • Individuals who have received three doses of the monovalent vaccine: A single dose of the bivalent vaccine should be given at least 2 months after the last dose of the monovalent vaccine.
  • Mandatory requirements for the administration of BNT162b2 under the EUA are as follows:
    • The vaccination provider must give the individual receiving the Pfizer-BioNTech COVID-19 vaccine or their caregiver the “Fact Sheet for Recipients and Caregivers” before the individual receiving the Pfizer-BioNTech COVID-19 vaccine.
    • Vaccine providers must include vaccine information to the state’s or local jurisdiction’s Immunization Information System or other designated systems.
    • Vaccine providers are responsible for reporting certain events to the Vaccine Adverse Events Reporting System (VAERS):
      • Vaccine administration errors, whether or not associated with an adverse event
      • Serious adverse events include death, life-threatening, inpatient hospitalization/prolonged hospitalization, persistent or significant incapacity, and congenital anomaly/birth defects.
      • Cases of multisystem inflammatory syndrome (MIS) in children and adults
      • Cases of COVID-19 that result in hospitalization and death
    • Vaccine providers are responsible for responding to FDA requests for information about vaccine administration errors, adverse events, cases of MIS in adults and children, and cases of COVID-19 resulting in hospitalization or death following administration Pfizer-BioNTech COVID-19 Vaccine to recipients.
  • There are limited data on the interchangeability of COVID-19 vaccines. If the primary series is initiated with the Pfizer-BioNTech product, the primary series should be completed with the Pfizer-BioNTech product.
    • Booster shots can be administered with any of the COVID-19 vaccines authorized in the U.S. (mRNA vaccines preferred; those aged 6 months - 17 years can receive only the Pfizer-BioNTech vaccine).
