evidence: This large population-based safety study found no evidence of increases in adverse neonatal events in infants born to individuals vaccinated against COVID-19 during pregnancy. In contrast, exposure to COVID-19 vaccination during pregnancy was associated with reduced rates of nontraumatic intracranial hemorrhage, hypoxic-ischemic encephalopathy, and neonatal mortality. The observed reduction in risk may reflect residual confounding rather than an actual protective effect of vaccination. However, these findings may provide reassurance to public health authorities, clinicians, pregnant individuals, and their families that infants are not at higher risk of adverse events due to COVID-19 vaccination during pregnancy.
