Neonatal outcomes after Covid-19 vaccination in pregnancy (6 February 2024)

Summary

This population-based cohort study from Sweden and Norway aimed to explore whether exposure to mRNA Covid-19 vaccination during pregnancy increases the risk of adverse events in newborn infants. The cohort included 94,303 infants exposed to Covid-19 vaccination during pregnancy and 102,167 control infants born between June 2021 and January 2023. The authors found that vaccination during pregnancy was associated with lower odds of neonatal intracranial haemorrhage, cerebral ischemia and hypoxic-ischemic encephalopathy, and neonatal mortality.
