## Contribution

It evaluates the necessity of monoclonal antibody prophylaxis for extremely preterm infants beyond their first RSV season.

## Key findings

- The study assesses RSV-related outcomes in extremely preterm infants during their second RSV season.
- Findings may inform guidelines on extended monoclonal antibody use for this vulnerable population.

## Abstract

This cohort study examines children in British Columbia, Canada, born between 2013 and 2024 to assess whether use of monoclonal antibodies for a second respiratory syncytial virus (RSV) season is warranted for extremely preterm infants.
