ABSTRACT
Objective: As approval of one of many coronavirus disease-2019 (COVID-19) vaccines' use for pregnancy is getting closer, vaccine hesitancy may take place in pregnant individuals for this new vaccine. Our study aimed to evaluate vaccine acceptance and factors affecting vaccine acceptance in case of an approved COVID-19 vaccine for pregnant individuals. Material and Methods: Our study was designed as one group, cross-sectional, prospective study. Sample consisted of pregnant individuals who didn't have any chronic illnesses and didn't contract COVID-19 in the last 6 months. In-person style survey was used to collect data about demographics, knowledge about COVID19 disease and it's effects on pregnant individuals, vaccine acceptance and reasons for acceptance or refusal. Results were analyzed with descriptive statistics, chi-square test and Shapiro-Wilk test of normality using Number Cruncher Statistical System. Results: Among 250 participants, 183 (73.2%) reported they wouldn't accept COVID-19 vaccination if there was a safe and effective vaccine approved for use in pregnancy. Main reasons of refusal were the belief that vaccine hadn't been studied on humans enough or that it might have adverse effectes on baby and/or pregnant individual. Only factor associated with vaccine acceptance was found to be knowing someone who had severe COVID-19 disease (p=0.022). Conclusion: Our study shows that vaccine hesitancy rates may be high among pregnant individuals when a COVID-19 vaccine is approved for use in pregnancy. The main reason for vaccine hesitancy is safety concerns.
