Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the impact of Nirsevimab, a monoclonal antibody used for RSV prophylaxis, on reducing RSV- related hospitalizations. It will be conducted at 8 pediatric departments in Tuscany, Italy. First, a matched case-control study investigates the real-world effectiveness of Nirsevimab in preventing RSV-related lower respiratory tract infection (LRTI) hospitalizations during the RSV epidemic season 2024-2025. Second, a descriptive study examines how the Nirsevimab immunization campaign affects RSV epidemiology, focusing on patients' age, comorbidities, infection severity, and clinical outcomes. The findings aim to optimize RSV prevention strategies and inform public health policies.
