Receiving an mRNA COVID-19 vaccine shortly before or at any point during pregnancy is not linked to autism or other developmental disorders in children, according to research presented at the Society for Maternal-Fetal Medicine (SMFM) 2026 Pregnancy Meeting. The findings provide new data on the long term health of children whose mothers were vaccinated around the time of pregnancy.
