Data on COVID-19 vaccination coverage in pregnancy are sparse, with most literature focused on original monovalent and bivalent vaccines. We assessed coverage of 2023-2024 COVID-19 vaccines among pregnant women across ten health care organizations in the United States participating in the Vaccine Safety Datalink (VSD). Among 167,478 women aged 18-49 years with a pregnancy during September 2023-August 2024, 23,941 (14.3%) received a 2023-2024 COVID-19 vaccine dose prior to or during their pregnancy. We identified higher coverage with increasing age groups (range 4.8% to 21.2% vaccinated) and increasing healthcare utilization during pregnancy (range 9.8% to 17.6% vaccinated). We found differences in coverage by maternal race and ethnicity (range 7.2% to 23.2% vaccinated), and by calendar month of pregnancy start (range 1.3% to 17.6% vaccinated). Uptake of 2023-2024 COVID-19 vaccines was low in this population. The VSD will continue monitoring COVID-19 vaccination coverage in pregnancy in the 2024-2025 season, including coverage by maternal race and ethnicity.
