Parents across Ireland are being encouraged to arrange free RSV immunisation for eligible babies as the 2026–2027 programme gets underway. The Health Service Executive (HSE) says protection before the winter season can help reduce the risk of serious respiratory syncytial virus illness and hospitalisation.
RSV is a common, highly contagious virus that usually causes mild respiratory symptoms. However, it can be particularly dangerous for young babies, especially during their first winter. The programme uses a single dose of nirsevimab, providing immediate protection throughout the main RSV season.
RSV immunisation eligibility and how babies receive protection
The route to RSV immunisation depends on a baby’s date of birth:
- Babies born from 1 September 2026 to 28 February 2027: immunisation will be offered in maternity hospitals before discharge, where possible.
- Babies born from 1 March to 31 August 2026: immunisation will be available through participating GP practices.
- Babies at increased risk of severe RSV illness: protection will be arranged through a specialist pathway.
The HSE describes the immunisation as free, safe and effective. It prevents more than 80% of RSV-associated hospitalisations, according to the programme information. Parents should contact their maternity hospital, participating GP practice or healthcare professional if they are unsure how to access the service.
Why early protection matters
RSV circulates most widely during autumn and winter. Receiving protection early in the season helps ensure babies are covered when infection levels are highest. The immunisation can also be administered alongside routine childhood vaccines, so parents generally do not need to postpone scheduled vaccinations because of RSV protection.
Strong results from Ireland’s previous RSV programme
The HSE said more than 37,000 infants received RSV immunisation last winter. Maternity-hospital uptake among babies born during the September-to-February period reached 88%, while uptake among high-risk infants was 100%.
The previous programme was associated with a 70% reduction in RSV-related hospitalisations among babies born during the RSV season. Across the eligible groups, the HSE estimates that immunisation prevented more than 1,000 emergency department presentations, hospitalisations and intensive-care admissions.
These results underline the value of early prevention and coordinated care between maternity hospitals, GP practices and specialist services. The HSE is asking parents to use official guidance and speak with a healthcare professional about their baby’s eligibility.
What parents should do
- Check whether your baby falls within the 2026–2027 eligibility dates.
- Ask the maternity hospital or participating GP practice about availability.
- Discuss any medical concerns or higher-risk conditions with your healthcare professional.

Frequently asked questions
What is RSV?
RSV is a seasonal respiratory virus. Although symptoms are often mild, infection can lead to serious lower respiratory illness in babies and young children.
What immunisation is used?
The programme provides one dose of nirsevimab, an antibody treatment designed to give immediate protection during the RSV season.
Can it be given with routine vaccines?
Yes. The HSE says RSV immunisation can be given safely alongside routine childhood vaccinations. Parents should follow advice from their healthcare professional.
With winter approaching, the key message is simple: eligible families should seek RSV immunisation as early as possible. The free HSE programme offers babies important protection during their most vulnerable months and can help reduce severe illness and pressure on hospitals.
