Babies of mothers who were vaccinated against COVID-19 while pregnant are less likely to die or have a serious health complication in their first six months, according to international researchers. The researchers used Canadian health databases to compare the health of 142,006 babies, 85,670 of which were exposed to at least one COVID-19 vaccination in utero. The researchers say those exposed to vaccination had lower rates of death, intensive care unit admission, hospital admission and severe morbidity within the first six months of life.

About The Study: In this study of 142,000 live births in Ontario, Canada, maternal mRNA COVID-19 vaccination during pregnancy was associated with lower risks of severe neonatal morbidity, neonatal death, and neonatal intensive care unit admission and no increase in neonatal readmission or hospital admission up to age six months, compared with no maternal COVID-19 vaccination before delivery.
