New COVID-19 boosters that target multiple strains now available

The Pfizer/BioNTech bivalent booster is available for individuals age 12 and older, while the Moderna bivalent booster is for those age 18 and older.

SAN DIEGO COUNTY, Calif. — The new COVID-19 bivalent boosters have arrived in San Diego County and limited supplies are now available at vaccination locations across the region, including pharmacies and medical providers.

The new bivalent boosters were developed to generate an immune response from the original COVID-19 virus, as well as the BA.4 and BA.5 Omicron subvariants.

The Pfizer/BioNTech bivalent booster is available for individuals age 12 and older, while the Moderna bivalent booster is for those age 18 and older. The bivalent boosters have not yet been authorized for children under the age of 12. Youths in that age group can get boosted with the previous version of the monovalent Pfizer vaccine.

San Diegans need to be fully vaccinated before receiving the new booster, meaning they must have received the two-dose primary series of Pfizer, Moderna, or Novavax, or at least one shot of the Janssen vaccine. These vaccinations are still widely available. Anyone who received a previous COVID-19 vaccine less than two months ago can get the bivalent booster shot eight weeks after their last shot.

“These new boosters are safe and effective at protecting people against the Omicron variants, which are currently causing the majority of new infections in our region,” said Cameron Kaiser, M.D., M.P.H., County deputy public health officer. “Supplies of the bivalent vaccine will initially be limited, so we ask anyone who is planning to get the new booster to be patient.”

Initially, County doses will be available at four County-operated locations:

South Region Live Well Center

150 doses a day

690 Oxford St, Chula Vista, 91911

10 a.m. to 5:30 P.M.

649 W. Mission Ave, Escondido 92025

9:45 a.m. to 4:30 p.m.

The bivalent boosters will be available in the state’s My Turn system in the near future and will be given on a first-come, first-serve basis. While the initial shipments of the vaccine have been limited, the County expects more doses to arrive in the coming days and weeks, with the next shipment expected to arrive as soon as Friday afternoon.
