Overview
- Regional campaigns began on Monday, September 21, 2026, with Córdoba and A Coruña starting local rollouts and other regions announcing plans for the season.
- Health services are giving nirsevimab, an extended‑half‑life monoclonal antibody that officials say cut hospital admissions by about 80% in Córdoba and by more than 90% in Galicia in prior seasons.
- Logistics differ by region with Córdoba offering a new drop‑in 'acto único' for a defined birth cohort and removing prescription and signed consent requirements while Galicia continues hospital‑based, staged call‑ups through 31 March 2027.
- Campaigns target infants by age and risk groups — very young babies, premature infants, and children with prior conditions — and build on high past uptake of roughly 4,987 children in Córdoba and 13,075 in Galicia.
- Officials urge parents to watch for bronchiolitis warning signs such as increased sleepiness, breathing difficulty and poor feeding and say the programme should reduce winter hospital pressure and ICU stays for previously healthy infants.
