NHS Flu Vaccination

When to book your NHS flu vaccination

The free NHS flu vaccine is offered each autumn and winter to people at higher risk of complications. You are eligible if you are:

• Aged 65 or over
• Pregnant, at any stage of pregnancy
• Living with a long-term condition such as diabetes, heart, kidney or liver disease, a chronic respiratory condition or a neurological condition
• Immunocompromised through illness or treatment
• A carer, or living with someone who is immunocompromised
• A frontline health or social care worker
• Living in a residential or nursing home
• A child aged 2 to 17, who are offered a nasal spray vaccine

The programme starts in September, and it takes around two weeks to build full protection, so get vaccinated early. UK flu season runs October to March, peaking between December and February. If you are unsure whether you qualify, our pharmacists will check.

Why the flu vaccine matters

Flu spreads through coughs, sneezes and contaminated surfaces. Unlike a cold it comes on suddenly, with a high temperature, body aches, exhaustion, dry cough, sore throat, headache and disturbed sleep lasting one to two weeks. It can lead to pneumonia, bronchitis and worsening of existing conditions.

• Cuts your chance of catching flu during the winter season
• Reduces the severity of symptoms if you do catch it
• Lowers the risk of serious complications and hospitalisation
• Protects vulnerable people around you
• Reduces pressure on the NHS over winter

How the vaccine works

The vaccine introduces inactivated flu virus proteins that cannot cause flu but prompt your immune system to produce antibodies, so your body can recognise and fight the real virus quickly. Flu viruses change every year, so a new vaccine is produced annually to match the expected strains, which is why yearly vaccination matters.

Side effects are usually mild and pass within a day or two: a sore arm at the injection site, a mild temperature or feeling slightly unwell, and aching muscles. Serious reactions are extremely rare. Tell your pharmacist if you have a severe allergy to egg proteins or any vaccine component.

Flu and other winter illnesses

Flu circulates alongside COVID-19, RSV and the common cold, and symptoms can overlap. If you are eligible for both the flu and COVID-19 vaccines, it is safe to have them at the same time. If you already have flu, our Flu Treatment Service can supply antivirals when started within 48 hours of symptoms.
