Bivalent enhancers available and encouraged | news

The San Diego County Health and Human Services Agency is encouraging San Diego residents to stay up to date on their COVID-19 vaccine doses ahead of the upcoming winter months.

“Covid-19 vaccines and boosters are our best protection against the virus, and I encourage anyone who is eligible for a booster to get one,” said Wilma J. Wooten, MD, MPH, Public Health Officer of the county “Although the numbers of COVID-19 are trending down, the virus remains active and infectious in our community and we anticipate more cases in the coming months as people move activities indoors.”

To date, nearly 1.45 million San Diegans have received a regular booster since they became available. The county has administered more than 400 bivalent boosters since limited supplies began arriving earlier this month, while the total from all providers has topped 34,000.

The new bivalent enhancers were developed to generate an immune response from the original COVID-19 virus as well as the Omicron BA.4 and BA.5 subvariants. Omicron variants are still causing the majority of new COVID-19 infections in the region.

Pfizer/BioNTech Bivalent Booster is available for people 12 years of age and older. Moderna’s bivalent boosters are licensed for people 18 and older, but are not currently available in the region as the county is awaiting additional vaccine allocations from the state.

Bivalent boosters have not yet been approved for children under 12 years of age. Young people in this age group can be boosted with the older version of Pfizer’s monovalent vaccine.

San Diegans must be fully vaccinated with the primary series of one of the approved COVID-19 vaccines before receiving a bivalent booster, meaning they must have received the two-dose primary series from Pfizer, Moderna, or Relatively new Novavax. All of these vaccines remain widely available. Those who received at least one shot of the Janssen vaccine, which is no longer widely available, are also eligible for the bivalent booster.

Anyone who wants to receive a bivalent booster must wait at least eight weeks after receiving a previous COVID-19 vaccine until they are eligible. Also, anyone who is fully vaccinated and has recently tested positive for COVID-19 should wait three months after infection to get a bivalent booster.
