evidence: The current study explored a broad range of neonatal morbidity outcomes after exposure to COVID-19 vaccination in pregnancy. Several of the neonatal outcomes were selected because they touched areas of interest in previous reports of possible adverse events associated with mRNA COVID-19 vaccines administered to children or adults.3,4,19 Suspected adverse events in adults and children—ie, events that have been observed following vaccination, but which were not necessarily related to or caused by the vaccine—that have drawn particular attention include coagulation disorders (thrombosis, bleedings), immune reactions (allergic reactions, Guillain-Barré syndrome), inflammation (myocarditis/pericarditis), and reports of deaths.3,4,19 [...] This study’s findings were robust across many different sensitivity analyses and are unlikely to be the result of a reduction in stillbirths or preterm births. Previous studies have not found that vaccination against COVID-19 during pregnancy influences the risk of miscarriage or stillbirth.10,27 However, COVID-19 infection was recently shown to increase the risk of stillbirth in this study population.28 Although vaccination may have reduced the rate of stillbirths and thereby increased the number of infants at risk for neonatal outcomes, the number of stillbirths was very low and unlikely to have substantially influenced vaccination estimates when restricting to live births.
