New Vaccine Guidance: Second Bivalent Boosters Available to Seniors


Centers for Disease Control and Prevention (CDC) updated its COVID-19 vaccine guidance and the LACounty Department of Public Health (Public Health) is asking everyone to check and make sure they have the most up-to-date protection available.

To put it simply, everyone ages 6 months and older should get at least one bivalent booster.

The CDC also made the following changes:

Adults 65 and older can get a second bivalent booster four months after their first one.

Immunocompromised people ages 6 and older can get a second bivalent booster two months after their first one.

The bivalent vaccines are replacing the monovalent vaccines. The monovalent vaccines were formulated for the original strain of COVID-19, while the bivalent formula protects against that and newer Omicron strains.

The bivalent vaccines were approved in September 2022, so anyone vaccinated before that date has not had a bivalent booster.

Second Bivalent Boosters Now Available for Seniors

Why Older Adults Especially Need Bivalent Boosters

Older adults remain among the most vulnerable to hospitalization and death due to COVID-19, making the protection offered by boosters especially important.

Studies and clinical data provide mounting evidence on the effectiveness of the bivalent vaccine at reducing the risk of symptomatic infection and severe illness, especially among people 65 and older.

Recent local data shows people 65 and older who were vaccinated, but didn’t have the bivalent booster, were twice as likely to be hospitalized and twice as likely to die from a COVID-19 infection than those who did get the bivalent booster.
