Flu occurs every year, usually in winter, which is why it’s sometimes called seasonal flu. It’s a highly infectious disease with symptoms that come on very quickly. The most common symptoms are fever, chills, headache, aches and pains in the joints and muscles, and extreme tiredness. Healthy individuals usually recover within 7 days, but for others, flu can be serious and even life-threatening.
It is important to get protected, even if you have had a vaccine or been ill with flu before, as immunity fades over time and flu viruses change each year. If you are vaccinated and catch flu this winter, you are likely to have milder symptoms and recover faster, cutting your risk of going to hospital.
Every autumn the NHS offers free vaccinations to those most at risk from serious flu complications.
From October 2025, free NHS flu vaccines are available for:
- anyone aged 65 or over
- people with certain long-term health conditions
- people who are pregnant
- people who live in a care home
- people who are the main carer for an older or disabled person, or receive a carer's allowance
- people who live with someone who has a weakened immune system; children aged 2 or 3 years on 31 August 2025
- school-aged children, Reception to Year 11
Flu vaccinations are available via your GP or pharmacist.
