A new study details dramatically lower confidence in COVID-19 vaccine safety in pregnant and recently pregnant women in 2023 compared to 2021, despite evidence to the contrary, according to findings published yesterday in JAMA Network Open.

The study was based on responses given in two survey waves from 2021 to 2023, with 1,227 total respondents. Wave 1 took place from October 2021 to February 2022, and wave 2 took place from November 2022 to February 2023

Participants, members of the Vaccine Safety Datalink (VSD), were asked about their vaccination status, race, ethnicity, and preferred language, as well as whether they somewhat or strongly agree with the statement that COVID-19 vaccines are safe.
