RSV: The little-known jab that could keep over 75’s out of hospital this winter.
There’s a winter virus which can be much more serious for those aged 75 and over. It’s a major cause of respiratory illness in the UK, often starting like a simple cold, but can quickly lead to pneumonia, breathing problems and even hospital stays in those who are most vulnerable.
What many people don’t realise is that the NHS now offers a vaccine that protects against this virus. It’s a newer offer for older adults, which is why you may not have heard much about it yet. But it can make a real difference to staying well and staying independent.
What’s the virus?
The virus is called RSV which stands for Respiratory Syncytial Virus. It spreads easily through coughs and sneezes and can hit older lungs much harder than expected. In over 75’s it can cause pneumonia and flare-ups of existing lung disease and other long-term conditions. It causes around 9,000 hospitalisations in those aged over 75 in the UK each year.
Why this vaccine matters:
The RSV vaccine can help protect you. A single dose:
- helps boosts protection for a few years
- helps prevent pneumonia
- reduces the risk of hospital stays
- supports staying active and independent
