About The Study: According to the results of this population-based surveillance study, during 2024-2025, both maternal respiratory syncytial virus (RSV) vaccine and nirsevimab were estimated to be effective at protecting infants from RSV-associated hospitalizations in their first RSV season, and RSV-associated hospitalization rates in newborns and infants ages 0 to 11 months were reduced by up to half compared to seasons before these products were introduced.
