Every year, flu leads to serious illness, hospital admissions, and avoidable pressure on healthcare services. As influenza is currently rising and reaching its seasonal peak. For some people, it can trigger severe complications.
To reduce these risks, the NHS offers a free flu vaccine to people most at risk of becoming ill or passing the virus on to others who are vulnerable. Eligibility is reviewed regularly, but the core groups remain consistent.
This guide explains who qualifies, why certain groups are prioritised, and how to check your eligibility for the NHS Flu vaccine in the UK.
The flu is a contagious infection that can cause high fever, body aches, exhaustion, headaches, and chest discomfort. Most people get better in a week or two, but the flu can lead to serious complications. These risks are higher for older adults, pregnant women, and people with long-term health conditions.
The NHS flu vaccine is the most reliable protection against catching flu. It also helps reduce the spread of illness within families and communities, especially among vulnerable populations. Having the vaccine protects your health and supports wider community protection.
The NHS flu vaccination programme focuses on groups where vaccination has the greatest health benefit.
People are prioritised because they:
By targeting these groups, the programme protects individuals while supporting the wider healthcare system.
Your eligibility is based on health risk, age, pregnancy, caring responsibilities, and exposure to vulnerable people. Below are the groups eligible for the NHS flu vaccine.
Some long-term health conditions make flu more dangerous. The NHS offers a free flu vaccine to help protect people whose immune systems or organs may struggle to cope with infection.
Health conditions that usually qualify include:
If you are unsure whether your condition qualifies, it is best to speak with a GP, practice nurse, or pharmacist. They can confirm eligibility based on NHS guidance.
Pregnant women are eligible for a free NHS flu vaccine at any stage of pregnancy. Flu during pregnancy can be more severe and may increase the risk of complications.
Vaccination helps protect:
Flu vaccines used by the NHS have a strong safety record in pregnancy and are recommended to protect both mother and baby.
The NHS flu vaccination programme also includes children, as flu spreads easily in schools and childcare settings.
Preschool children
Eligibility is based on age and follows national NHS guidance.
School-aged children
Vaccination is usually delivered through the school immunisation programme.
Children with health conditions
Children with certain long-term health conditions qualify regardless of age, as clinical risk takes priority over age-based criteria.
Carers play an important role in supporting people who may be vulnerable to flu and its complications. Many carers qualify for a free NHS flu vaccine.
This includes:
Vaccinating carers helps reduce the risk of passing flu to those who may be less able to fight infection.
Health and social care workers are at increased risk of exposure to flu and may pass it on to patients or service users.
The NHS flu vaccine is offered to:
Vaccination helps protect patients, colleagues, and the wider healthcare system by reducing sickness and staff absence.
Some people do not meet the criteria for a free NHS flu vaccine.

In these cases, private flu vaccination may still be appropriate and can offer useful protection during flu season.
If you are eligible, the NHS flu vaccine is available from:
All providers follow the same NHS eligibility rules and safety standards.
You can confirm your eligibility by:
If you are unsure, it is always better to check than to miss out on protection.
Flu vaccination works best when given before flu starts circulating widely.
Getting vaccinated at the right time helps reduce your risk throughout the flu season.
Flu vaccines used by the NHS are carefully tested and monitored.
Serious side effects are rare, and the benefits of vaccination outweigh the risks for eligible groups.
If you are not eligible for a free NHS flu vaccine, you can still protect yourself with a private flu jab. At The Care Pharmacy, you can book a flu vaccination appointment quickly and get support from a trained pharmacy team in a safe, professional setting.
But why should you choose The Care Pharmacy for a private flu jab?
The appointment is simple from start to finish. We will first check a few quick health questions, administer the vaccine, and then share practical advice on which side effects to watch for and when to seek medical help.
You qualify for a free NHS flu jab if you’re 65 or over, pregnant, have long-term conditions, are a carer, or live with immunocompromised people.
Who can have a free flu vaccination?
Free flu vaccination includes children (2–3 on 31 August, Reception–Year 11, or clinical risk), pregnant people, carers, and health or social care staff.
How long does flu shot immunity last?
Flu shot immunity lasts around six months. Protection peaks after two weeks, then slowly decreases, which is why a new flu vaccine is recommended every year.
What is the difference between the flu jab for over 65 and under 65?
People over 65 get a stronger, enhanced flu vaccine for better protection. People under 65 usually receive the standard flu vaccine unless they are in a high-risk group.
