Objective:To describe and determine the association between Covid-19 vaccination in pregnancy and placental pathology.Methods:Conducted in a tertiary hospital in Medan,Indonesia,from April 30th 2022 to June 30th 2022,this single-center cross-sectional study involved Covid-19 vaccinated and unvaccinated women with singleton full-term pregnancies delivering live fetuses via cesarean section.Maternal characteristics,placental pathologies,and the placental index were documented at enrollment.The association between Covid-19 vaccination status and placental pathology was assessed.Results:The study enrolled 200 pregnant women,including 110 vaccinated women and 90 unvaccinated women.No significant differences were observed in birthweight(P=0.48),placental index(P=0.48),and placental pathology findings[intervillous bleeding(P=0.20),increased syncytial knots(P=0.83),chorangiosis(P=0.13),villous stromal edema(P=0.13),vascular dilation and congestion(P=0.13),and vascular wall thrombus(P=0.71)]between the vaccinated and unvaccinated groups.Conclusions:This study revealed no statistically significant association between Covid-19 vaccination and placental pathology.The findings support the safety of Covid-19 vaccination during pregnancy,in regards to changes of the placental pathology.
