Study Design:A prospective multicenter cohort study was conducted across nine U.S. academic sites, enrolling infants born to mothers vaccinated with 2- (n=280) or 3-dose (booster) monovalent mRNA vaccines during pregnancy (n=202) or postpartum (n=36). Primary Outcomes: Antibody Levels: Significantly higher geometric mean titers (GMTs) of binding and neutralizing antibodies (nAb) were observed at birth and 2 months in infants of mothers who received a booster dose during pregnancy compared to those who received 2 doses or were vaccinated postpartum. Sustained Antibody Levels: Higher titers against the vaccine strain persisted up to 6 months in infants of boosted mothe
