Vaccination is preventing development of placental pathologies in SARS-CoV-2 infected pregnant patients.

INTRODUCTION: The coronavirus disease (COVID-19) has created a serious health problem in pregnant people. We aimed to address whether vaccination can prevent development of placental disease in SARS-CoV-2 infected mothers. METHODS: We reported the pathology findings obtained from routine histopathological examination of placentas of overall 38 cases. RESULTS: We found low prevalence of placental pathology in vaccinated pregnant people with active SARS-CoV-2 infection in comparison to those unvaccinated cases. CONCLUSION: Based on our findings, SARS-CoV-2 vaccination can prevent development of placental pathological lesions and may lower the risk of serious illness in pregnant people.
