Brief Summary

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

A longitudinal observational study based on routinely collected data on hospital and health care use for RSV infections will be undertaken. The Galician public health registries will be used for data collection including baseline information and follow-up data. Historical data will be retrieved for comparison purposes. The study aims to observe and analyze data from all the eligible children in Galicia for nirsevimab treatment. The number of eligible children is expected to be approximately 14,000 per each RSV season.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to evaluate the impact of nirsevimab in preventing RSV in healthy infants and high-risk children less than 24 months of age at the start of RSV season in Galicia.

The target population to receive nirsevimab is around 14,000 subjects including all healthy newborns during the RSV season, those \< 6 months at the start of the season, as well as those \< 24 months with comorbidities at the start of the season. Nirsevimab will be administered as part of the immunization program of Galicia and following the implementation plan designed by the Public Health authorities, using the vaccination facilities of the Galician system, i.e., hospitals and primary care centres. Appointments for administration and registration of administered doses will be performed as per usual immunization protocols. The expected coverage with nirsevimab in the target population is expected to be high (\>80%).

RSV testing is routinely performed in the hospital and emergency department settings. The Galician Regional Surveillance Information System will retrieve all the existing information of the different electronic databases for new RSV cases detected in Galicia, including hospitalization, primary care, drug administration and immunization. RSV case ascertainment and classification will be per- formed by a specialized clinical team according to pre-established definitions.
