| Description: |
Background During the 2023-2024 and 2024-2025 respiratory virus seasons, two products, a maternal vaccine (Abrysvo, by Pfizer) and an infant monoclonal antibody (nirsevimab), were recommended in the United States to protect infants against severe respiratory syncytial virus (RSV) disease during their first RSV season. We estimated product effectiveness (PE) against RSV-associated emergency department (ED) encounters and hospitalizations among infants in their first RSV season during these seasons.Table 1.Nirsevimab effectiveness against RSV-associated ED encounters and hospitalization among infants in their first RSV season, VISION, 2023-2024 and 2024-2025 RSV seasonsRSV = respiratory syncytial virus; ED = emergency department; IQR = interquartile range; CI = confidence interval; Ref = reference group; PE = product effectiveness; VISION = Virtual SARS-CoV-2, Influenza, and Other respiratory viruses Network*Encounters included those among infants aged |
