Is it true that COVID-19 mRNA vaccination during pregnancy is associated with a lower risk of SARS-CoV-2 infection in children in early childhood, according to a 2026 study?

Unclear. Three 2026-dated sources report that COVID-19 mRNA vaccination during pregnancy, especially in late pregnancy, is associated with lower risk of COVID-19 in infants during the first months of life, but they cover only early infancy rather than early childhood.
