Recent Vaccine Updates Provided by LA County Public Health

The difference between third doses and booster doses is more than just a language issue. Third doses are meant to elicit an antibody response where there was an inadequate antibody response before, while booster doses are meant to increase antibody levels that have waned after a robust increase in the months after vaccination.


With emerging data indicating that certain populations will need more support to be protected, the CDC’s Advisory Committee on Immunization Practices on August 13th recommended a third dose of mRNA vaccines for immunocompromised people, including transplant recipients, people with advanced or untreated HIV infection, people actively receiving cancer treatment, and people taking immunosuppressive medications. Third doses have been available to eligible individuals at vaccination sites across the county since Saturday, August 14th.

Additionally, following yesterday’s announcement by the CDC that booster doses of mRNA vaccines will be offered to all vaccinated people,  we are continuing to work with staff and residents at skilled nursing facilities to prioritize these most vulnerable residents for booster doses so we are prepared to administer these as soon as the Food and Drug Administration gives their approval.
