This page is about the flu vaccine for adults. There are also pages about the children's flu vaccine and flu jab in pregnancy.

Who should have the flu vaccine

The flu vaccine is recommended for people at higher risk of getting seriously ill from flu.

It's offered on the NHS every year in autumn or early winter.

You can get the free NHS flu vaccine if you:

are aged 65 or over (including those who will be 65 by 31 March 2025)
have certain long-term health conditions
are pregnant
live in a care home
are the main carer for an older or disabled person, or receive a carer's allowance
live with someone who has a weakened immune system

Frontline health and social care workers can also get a flu vaccine through their employer.

Health conditions that mean you're eligible for the flu vaccine

The flu vaccine is recommended for people with certain long-term health conditions, including:

conditions that affect your breathing, such as asthma (needing a steroid inhaler or tablets), chronic obstructive pulmonary disease (COPD) or cystic fibrosis
heart conditions, such as coronary heart disease or heart failure
chronic kidney disease
liver disease, such as cirrhosis or hepatitis
some conditions that affect your brain or nerves, such as Parkinson's disease, motor neurone disease, multiple sclerosis or cerebral palsy
diabetes or Addison's disease
a weakened immune system due to a condition such as HIV or AIDS, or due to a treatment such as chemotherapy or steroid medicine
problems with your spleen, such as sickle cell disease, or if you've had your spleen removed
a learning disability
being very overweight – a body mass index (BMI) of 40 or above

Speak to your GP surgery or specialist if you have a health condition and you're not sure if you're eligible for the flu vaccine.

How to get the flu vaccine

If you're eligible for an NHS flu vaccine, you can:

book a flu vaccination appointment at a pharmacy online or in the NHS App (if you're aged 18 or over)
find a pharmacy that offers NHS flu vaccination (if you're aged 18 or over)
contact your GP surgery to book an appointment

Some people may be able to get vaccinated through their maternity service, care home, or their employer if they are a frontline health or social care worker.

Frontline health or social care workers

Frontline health and social care workers should get the flu vaccine through their employer.

If you cannot get a flu vaccine through your employer, you can get it at a pharmacy or your GP surgery if you're employed:

by a registered residential care or nursing home
by a registered domiciliary care provider
by a voluntary managed hospice provider
through direct payments or personal health budgets

Having the flu vaccine at the same time as other vaccines

You can have the flu vaccine at the same time as other vaccines such as the COVID-19 and shingles vaccines.

It's not usually given at the same time as the RSV vaccine, but you can have them at the same time if a doctor or nurse thinks it's needed.

Who cannot have the flu vaccine

Most people who are eligible for the flu vaccine can have it.

You only cannot have the vaccine if you've had a serious allergic reaction (anaphylaxis) to a previous dose of the vaccine or an ingredient in the vaccine.

Some of the flu vaccines used in the UK contain egg protein. Tell the person vaccinating you if you have an egg allergy.

Getting vaccinated if you're unwell

If you have a high temperature, wait until you're feeling better before having your flu vaccine.

Flu vaccine ingredients

There are several types of flu vaccine given in the UK. If you're eligible for the flu vaccine on the NHS, you'll be offered one of the types that's most appropriate for you.

You can check the ingredients in the patient leaflets.

Vaccines for people aged 65 and over

Vaccines for people aged 60 to 64

Vaccines for people aged 18 to 59

Side effects of the flu vaccine

The most common side effects of the flu vaccine are mild and get better within 1 to 2 days.

They can include:

pain or soreness where the injection was given
a slightly raised temperature
an aching body

More serious side effects such as a severe allergic reaction (anaphylaxis) are very rare. The person who vaccinates you will be trained to deal with allergic reactions and treat them immediately.

The injected flu vaccines used in the UK do not contain live flu viruses. They cannot give you flu.

How well the flu vaccine works and how long it lasts

The flu vaccine aims to protect you against the most common types of flu viruses.

There's still a chance you might get flu after getting vaccinated, but it's likely to be milder and not last as long.

The vaccine usually takes up to 14 days to work.

Protection from the flu vaccine goes down with time and the types of flu virus the vaccine protects against are updated each year. This is why it's important to get the flu vaccine every year.
