NCT ID NCT07177508
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looked at how a new medicine called nirsevimab affected RSV infections and hospital stays in children under 2 years old in the Australian Capital Territory. Researchers used routine health data from over 2,300 kids to compare RSV cases and emergency visits before and after the medicine was introduced. The goal was to see if nirsevimab helped reduce the burden of RSV in real-world settings.
