Infant RSV Hospitalizations Plummet Amid Vaccination Efforts

Infant hospitalizations due to RSV have significantly decreased following the 2023 introduction of immunizations. For instance, South Shore Hospital saw admissions drop from 264 children in the 2022-2023 season to 117 in 2024-2025. Doctors report not only fewer hospitalizations but also reduced severity of illness among those admitted.

However, recent changes in federal recommendations by Health Secretary Robert F. Kennedy Jr. have removed RSV immunizations from routine childhood schedules, now only advising them for high-risk infants. This decision contrasts with findings that most infants admitted to ICUs for RSV had no underlying health conditions.

In response, most Massachusetts hospitals and the American Academy of Pediatrics maintain universal RSV immunization recommendations for newborns. The Massachusetts Department of Public Health advises physicians to follow the pediatric professional group's guidance over the CDC's revised stance.
