Weekly Percent of Pregnant Women Ages 18-49 Years Vaccinated with Respiratory Syncytial Virus (RSV) Vaccine Overall and by Race and Ethnicity

Weekly RSV Vaccination Coverage, Pregnant Women 18-49 Years Old by Race and Ethnicity Weekly RSV vaccination coverage estimates for pregnant women 18–49 years are based on electronic health record (EHR) data from the Vaccine Safety Datalink (VSD), a collaboration between CDC's Immunization Safety Office and multiple integrated health care organizations.* The denominator includes those who reached at least 32 weeks' gestation since September 1, 2025.

The numerator includes those who have received an RSV vaccine during pregnancy as of the week ending date. Pregnant women are not removed from the numerator or denominator when the pregnancy ends. Cumulative vaccination coverage for one week may be lower than cumulative coverage for a previous week due to the addition of pregnant women in the denominator.
