Omicron COVID-19 Bivalent Vaccine Advisory for Healthcare Providers

New Omicron COVID-19 Bivalent Vaccine Boosters Approved

Posted Sept. 22, 2022. Past health advisories and alerts are archived for historical purposes and are not maintained or updated.

SRHD’s Immunization Assessment & Promotion Program would like to clarify some of the recent changes in the administration of the COVID-19 booster doses.

What has changed?

  • The new boosters are single dose bivalent vaccines that combine the original COVID-19 vaccine with BA.4 and BA.5 variant protection.
    • Note: The primary COVID-19 vaccine series remains unchanged (monovalent vaccine).
  • Monovalent boosters are no longer authorized for persons aged 12+ years old. (They should receive a bivalent booster instead.)

When to administer?

  • Patients must complete the primary series with a monovalent COVID-19 vaccine before they can receive a bivalent booster.
  • Bivalent boosters may be given at least two months after completion of primary series or most recent booster shot.
  • Please note the immunocompromised primary series is still elongated and must be completed prior to administering the new bivalent booster.

Who can receive a bivalent booster?

  • Persons aged 12-17 years can receive the Pfizer-BioNTech bivalent booster.
  • Persons aged 18+ years can receive either Moderna or Pfizer bivalent booster.
  • Please note Novavax recipients are now eligible for the new boosters.

Who cannot receive a bivalent booster?

  • Persons aged 5-11 years should continue to receive monovalent booster, given 5 months after most recent dose.
  • Persons aged 6 months – 4 years are not authorized for any COVID-19 booster.
