These archived cumulative COVID-19 vaccination coverage estimates are for persons who were pregnant anytime from December 20, 2020, to January 20, 2022, and received at least 1 dose of COVID-19 vaccine during pregnancy based on data from the Vaccine Safety Datalink*. As of January 20, 2022, after moving to reporting weekly estimates, the figures on https://covid.cdc.gov/covid-data-tracker/#vaccinations-pregnant-women no longer present cumulative estimates, and these archived data are no longer updated.

For these cumulative data, on December 15, 2021, an error was identified where pregnant people who had received an additional or booster dose of a COVID-19 vaccine were not included in the coverage estimates. After correcting the error, coverage estimates for the week of December 11, 2021, increased overall and by race/ethnicity. The persons that were inadvertently excluded have been counted in the December 11, 2021, estimates. Prior weeks’ estimates have not been updated.
