Core Insights - A universal RSV immunization program using Beyfortus (nirsevimab) significantly reduced RSV-related hospitalizations in infants during their second RSV season after immunization in their first season [1][3] Group 1: Study Findings - The NIRSE-GAL study in Galicia, Spain, demonstrated a 94.4% coverage rate with 11,796 out of 12,492 eligible infants immunized [2] - There was an 85.9% reduction in RSV-related lower respiratory tract infection (LRTI) hospitalizations during the first season [2][6] - Infants who received Beyfortus during infancy experienced a 55.3% reduction in hospitalizations during their second RSV season [2] - The study also reported a 78.2% reduction in RSV-related rehospitalizations and a 62.4% reduction in LRTI rehospitalizations during the second season [4] Group 2: Implications for Public Health - The findings support the hypothesis that early protection against RSV-related lung damage may have lasting benefits on respiratory health [4] - The results provide compelling data to inform infant immunization strategies and economic evaluation models [3] Group 3: About Beyfortus - Beyfortus is designed to protect all infants during their first RSV season, including those born healthy at term or preterm, and those with health conditions [9] - It is a long-acting monoclonal antibody with an extended half-life of 71 days, administered as a single dose [10] - Over 11 million infants have been immunized with Beyfortus across more than 45 countries since its launch [11]
