The Los Angeles County Department of Public Health (LAC DPH) issued a health advisory on October 6, 2023. This advisory shares information about preventing severe respiratory syncytial virus (RSV) disease in infants.
Key Messages
-
There are now two immunization methods available to prevent severe respiratory syncytial virus (RSV) disease in infants: maternal RSV vaccination and infant immunization with RSV monoclonal antibody.
-
The CDC and American College of Obstetricians and Gynecologists (ACOG) recommend maternal RSV vaccination to protect infants from severe RSV disease. Pregnant people who are 32 through 36 weeks pregnant during September through January should get a single dose of Pfizer’s bivalent RSVpreF vaccine (Abrysvo).
-
Either maternal or infant RSV immunization is recommended. Most infants will not need both. Providers should counsel families on both immunization options.
-
It is vital that all maternal RSV vaccines administered are entered into the California Immunization Registry (CAIR). Pediatric providers will require this information to assess the eligibility of infants for RSV immunization.
