RSV Mortality Burden Falls Heavily on Older Children With Complex Conditions
A U.S. multicenter analysis of pediatric intensive care admissions from 2017 to 2023 found that children aged 2 and older accounted for nearly half of RSV-related ICU cases and two-thirds of RSV-related deaths. Most deaths in this older group occurred in children with at least one complex chronic condition, and those with three or more such conditions were 22 times more likely to die than those without. The findings highlight a gap in current RSV immunization recommendations, which do not cover children aged 2 to 17.
The analysis drew on records from over 100 U.S. health systems, capturing 13,732 pediatric ICU admissions across a six-year span. Among children who died, the median age was 9.1 years, notably higher than the 6.5-year median among survivors, underscoring how the burden shifts toward older pediatric populations.
Specific conditions tied to elevated mortality risk included malignancies, neurologic or neuromuscular disorders, respiratory ailments, and transplant recipients. Current immunization guidance excludes children aged 2 through 17, leaving this vulnerable group without approved preventive options despite their disproportionate share of severe outcomes.
This study may prompt reconsideration of who qualifies for RSV protection, particularly as immunization policy undergoes federal review. Families of children with complex medical conditions could face difficult decisions about prevention options that remain unapproved for older age groups. Hospitals and pediatric intensive care units may see continued strain from RSV seasons if this high-risk population remains uncovered, potentially affecting resource allocation and care planning for medically fragile children nationwide.
