Pregnant Women COVID-19 Vaccination Coverage
Weekly COVID-19 vaccination coverage estimates for pregnant women ages 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.* Additional data on COVID-19 vaccination coverage for pregnant women are available.
The denominator includes women with a pregnancy during the respective season† beginning before or during the specified week. The numerator includes those who received a COVID-19 vaccine after the vaccine was available for the respective season‡ before or during pregnancy as of the specified 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.±
Weekly comparisons to previous season should take into account differences between seasons in vaccine availability dates.‡

†For the 2025–26 season the denominator included women who were pregnant as of August 27, 2025. For the 2023–24 season the denominator included women who were pregnant as of September 26, 2023, and for the 2024–25 season the denominator includes women who were pregnant as of September 5, 2024. These dates are approximately two weeks after COVID-19 vaccines were approved each season.
‡2023–24 COVID-19 vaccines were first available mid-September 2023, and 2024–25 and 2025–26 COVID-19 vaccines were first available at the end of August 2024 and August 2025, respectively.
