The COVID-19 vaccines are highly effective in preventing COVID-19 illness; however, pregnant people were not included in the original COVID-19 vaccine trials, with resultant conflicting recommendations from health organizations regarding vaccinations for this high-risk population. Pregnant and lactating healthcare workers (HCWs), along with people planning a pregnancy, identified as "obstetric HCWs" in our study, were among the first to make decisions regarding vaccinating themselves against COVID-19. Given that HCWs are key sources of information and access to vaccinations, this study was conducted to understand the perceptions and knowledge of obstetric HCWs regarding the COVID-19 vaccine. An electronic survey to HCWs at a tertiary care institution in Pittsburgh, PA identified 83 obstetric HCWs, of which 65 (78.3%) received at least one dose of the either the Pfizer or Moderna COVID-19 vaccine, and 18 (21.7%) had not received any doses of vaccine. Pregnancy status influenced more people not to receive than to receive the vaccine. We found that both vaccinated and non-vaccinated obstetric HCWs had accurate knowledge regarding the COVID-19 vaccine. However, compared to non-vaccinated obstetric HCWs, vaccinated obstetric HCWs tended to endorse beliefs regarding herd immunity, believed they had a higher chance of acquiring COVID-19, and felt that the COVID-19 vaccine was safe for fetuses and people who were pregnant, lactating, breastfeeding, or planning a pregnancy. This study offers insight into obstetric individuals' perceptions and knowledge of the COVID-19 vaccine, and highlights areas where additional education and outreach may help obstetric individuals make informed decisions on receiving the COVID-19 vaccine.
