The aim of this cross-sectional study was to determine pregnant women's knowledge and attitudes regarding coronavirus vaccines in Turkiye. The research population consisted of 400 pregnant women who applied to a public hospital in this city. The data of the study was collected with the 'Personal Information Form' and 'Attitudes Towards COVID-19 Vaccine Scale'. Only 2% of the pregnant women stated that they wanted to receive coronavirus vaccines in their current pregnancy and 9.5% wanted it during the postpartum period. It has been concluded that the vast majority of pregnant women have insufficient knowledge and negative thoughts about coronavirus vaccines and the place where they live and their thoughts on the safety of coronavirus vaccines affect their positive attitudes about coronavirus vaccines.
