Respiratory syncytial virus (RSV) vaccine - Respiratory syncytial virus (RSV) vaccination information

Before the RSV vaccine was introduced in the UK, about 33,500 children under five needed hospital care because of RSV each year. RSV also caused 20 to 30 deaths in children each year.

Recent research shows that the RSV vaccine can lower the chance of being admitted to hospital. In people aged 75 to 79 years, it reduces this risk by around 75%.

Why have an RSV vaccination programme? 

The RSV programme was introduced to help protect babies and older adults from serious illness each autumn and winter. The programme also aims to reduce the need for hospital care and GP visits caused by RSV.  

The NHS started the RSV vaccination programme in Wales in September 2024. 

Risk groups 

Maternal programme to protect babies

RSV can make newborn babies and infants very unwell. 

It can cause lung infections called bronchiolitis or pneumonia. These conditions can make it hard for babies to breathe and to feed. They may need hospital care to help them get better.

The RSV vaccine is offered during pregnancy. It helps protect babies against serious illness caused by RSV during their first months of life.

Programme for older adults

RSV can cause severe breathing problems in older adults. Those who are frail or have other health conditions are at greater risk. RSV infection might cause pneumonia (infection of the lungs) or even death.
