ABSTRACT
OBJECTIVES: This study aimed to explore perceptions and willingness to get coronavirus disease 2019 (COVID-19) booster vaccination among pregnant and lactating women in Jordan. METHODS: A cross-sectional study using a 29-item web-based questionnaire was conducted. Sociodemographic characteristics, vaccine acceptance, confidence in the booster dose of COVID-19 vaccine, perception of risk for COVID-19, and acceptance to participate in COVID-19 booster vaccine clinical trials were prospectively evaluated. Logistic regression was used to identify factors that might affect the participants' acceptance of a COVID-19 vaccine and their willingness to enroll in clinical trials of a booster dose of COVID-19 vaccine. RESULTS: Among all participants (pregnant and lactating women, n = 584), 328 (56.2%) intended to receive the booster dose of the COVID-19 vaccine. Predictors of booster dose acceptance were a medical-related degree (OR 1.62, CI 1.06-2.5, p = 0.028), income (OR 0.677, CI 0.52-0.88, p = 0.004), living residency (OR 0.44, CI 0.32-0.60, p < 0.001), knowing pregnant/lactating women previously infected with infectious microbe (OR 1.539, CI 1.07-2.23, p = 0.022), commitment to immunization for children (OR 3.01, CI 1.03-8.82, p = 0.044), receiving an influenza vaccine (OR 1.46, CI 1.04-2.05, p = 0.031), and worried about infectious microbes (OR 1.32, CI 1.15-1.52, p < 0.001). Among participants, only 22.9% were willing to participate in clinical trials of the booster dose of COVID-19 vaccine. The biggest motivator for participation was the participants' desire to help find the best vaccine during pregnancy/lactation (57.5%) while the main barrier towards participation was not wanting to expose themselves and their babies to more side effects (88.0%). CONCLUSION: This study reported reasonable acceptance of vaccination in a sample of pregnant/lactating women. Vaccination hesitancy for the booster dose was in-line with similar studies on the primary series around the globe, but the willingness to participate in clinical trials was lower than non-pregnant/non-lactating women.
