Neonatal infection with the G10P[11] strain was not sensitive to the inhibitory effect of maternal antibody levels (a trait also reported for the G3P[6] oral human neonatal rotavirus vaccine candidate RV3-BB27), potentially reflecting serotype-specific adaptation to the newborn gut28 alongside reduced exposure to RV-IgA and other antiviral compounds if infection occurs prior to breastfeeding. The gene discussed is CD79A; the disease is infection.
