Flu is a common respiratory virus, spread through the air when you cough or sneeze. It can also spread when you touch surfaces where the virus has landed, then touch your eyes, nose or mouth.
For most people flu can cause unpleasant symptoms, but if you are vulnerable flu can cause severe illness. Symptoms of flu include:
- a high temperature
- tiredness
- a headache
- aches and pains
- a dry chesty cough
Flu vaccine
The flu vaccine is the safest and most effective way to help protect against flu. It will also help reduce the risk of spreading flu to others.
This year, the free flu vaccine is being offered on the NHS to adults who:
- are 65 and over (including those who will be 65 by 31 March 2024)
- have certain health conditions
- are pregnant
- are in long-stay residential care
- receive a carer’s allowance, or are the main carer for an older or disabled person who may be at risk if you get sick
- live with someone who is more likely to get infection due to a weakened immune system, such as someone who has HIV, has had a transplant or is having certain treatments for cancer, lupus or rheumatoid arthritis
- frontline health or social care workers
- have a serious long-term health condition
