The COVID-19 virus appeared in Wuhan, China in 2019 and spread rapidly all over the world. Vaccination guidelines have recommended pregnant women to get vaccinated against COVID-19 to prevent disease. This study aimed to understand the willingness of pregnant women to vaccinate and the factors associated with their hesitation and resistance. This cross-sectional study was conducted between March and April 2022. The sample size was not calculated and tried to reach all pregnant women who did not have any COVID-19 vaccine. In the first part of the questionnaire, socio-demographic questions, and in the last part, the short form of the 12-item anti-vaccine scale, which was prepared as a 5-point Likert scale, were applied. The study was completed with 561 pregnant women. The mean score of the pregnant women who participated in this study from the vaccine hesitancy scale was found to be 33.40 ± 6.07. It was found that as the income of pregnant women decreased, the vaccine hesitancy scores decreased. Vaccine hesitancy scores of those who stated no one gave advice were significantly higher. The vaccination of pregnant women will bring significant success to the fight against the COVID-19 pandemic when implemented as part of the public health policies of countries.
