NCT06180993

Brief Summary

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.
