Characteristics and perceptions associated with COVID-19 vaccination hesitancy among pregnant and postpartum individuals: A cross-sectional study.

ABSTRACT

OBJECTIVE: To assess the frequency and associated characteristics of COVID-19 vaccine hesitancy among pregnant and postpartum individuals. DESIGN: Cross-sectional study. SETTING: Prenatal care at a single academic tertiary care centre. POPULATION Pregnant and postpartum individuals enrolled in prenatal care at a single academic tertiary care centre from 22 March 2021 to 2 April 2021, concurrent with state guidelines recommending COVID-19 vaccination in pregnancy. METHODS: We used logistic regression to identify characteristics associated with COVID-19 vaccine hesitancy, and adjusted for age, parity, race, trimester of pregnancy, and chronic comorbidities. MAIN OUTCOME MEASURES: COVID-19 vaccine hesitancy, defined as uncertainty or refusal of the vaccine, despite the availability of vaccine services, in accordance with the World Health Organization (WHO) Strategic Advisory Group of Experts (SAGE) on vaccine hesitancy. RESULTS: Of the 485 individuals screened and approached, 456 (94%) enrolled and completed the survey (435/456, 95% pregnant). The frequency of COVID-19 vaccine hesitancy was 46% (95% CI 41%-51%). Sociodemographic characteristics, including non-Hispanic Black race, younger age, lower education, public health insurance receipt, parity >1, and reported substance use, were associated with a higher odds of COVID-19 vaccine hesitancy, but not clinical risk conditions. Individuals who had a family or friend vaccinated for COVID-19, prior or planned vaccination for tetanus, diphtheria and acellular pertussis (Tdap) and/or influenza, and who perceived that vaccination benefited the baby were less likely to express COVID-19 vaccine hesitancy. CONCLUSIONS: COVID-19 vaccine hesitancy was frequent among pregnant and postpartum individuals. Those who may face barriers to accessing healthcare services were more likely to report vaccine hesitancy. These results can inform interventions to increase COVID-19 vaccine uptake in pregnancy. TWEETABLE ABSTRACT COVID-19 vaccination hesitancy is frequent among pregnant and postpartum individuals, and those who face barriers to accessing healthcare services are more likely to report COVID-19 vaccine hesitancy.
