Question  Does exposure to mRNA COVID-19 vaccination during pregnancy increase the risk of adverse events in newborn infants? [JAMA Network]

Findings  In this population-based cohort study from Sweden and Norway that included 94 303 infants exposed to COVID-19 vaccination during pregnancy and 102 167 control infants born between June 2021 and January 2023, vaccination during pregnancy was associated with lower odds of neonatal intracranial hemorrhage, cerebral ischemia and hypoxic-ischemic encephalopathy, and neonatal mortality.

Meaning  In this large population-based study, vaccination of pregnant individuals with mRNA COVID-19 vaccines was not associated with increased risks of neonatal adverse events in their infants.
