Respiratory Syncytial Virus (RSV) Vaccination Coverage, Pregnant Women, United States

Pregnant Women RSV Vaccination Coverage

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, 2024.^† 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.^§Additionally, no requirements for length of enrollment in a VSD site are applied, and vaccinations given outside of a VSD site might not be included.

^{†Pregnant women who were past the recommended window of 32-36 week's gestation prior to September 1, 2024, were removed from the denominator. The denominator may include pregnant women 32–36 weeks of pregnancy as of September 1, 2024 or later, who received an RSV vaccine during a previous pregnancy. These pregnant women are therefore not eligible for another RSV vaccine this season/pregnancy; however, their infants would be eligible to receive nirsevimab.}
