The children's flu vaccine is safe and effective. It's offered every year as a nasal spray to children to help protect them against flu.
Children spread flu easily. Vaccinating them also protects others who are vulnerable to flu, such as babies and older people.
If you have any questions about vaccinations, you can:
- ask your GP surgery or other healthcare professionals for advice
- read more about why vaccination is safe and important
Routine vaccinations for babies, pre-school children and adults are continuing as normal.
Changes have been made to make sure it's safe for your child to have the flu vaccine at GP surgeries or at school. These changes include social distancing, hand washing and wearing protective equipment.
It's important to go to your appointments unless you, your child or someone you live with has symptoms of coronavirus.
Who should have the nasal spray flu vaccine
The nasal spray flu vaccine is free on the NHS for:
- children aged 2 or 3 years on 31 August 2020 – born between 1 September 2016 and 31 August 2018
- all primary school children (reception to year 6)
- all year 7 in secondary school
- children aged 2 to 17 years with long-term health conditions
If your child is aged between 6 months and 2 years and is in a high-risk group for flu, they'll be offered a flu vaccine injection instead of the nasal spray.
This is because the nasal spray is not licensed for children under 2 years.
Children aged 2 to 17 years may also have the flu vaccine injection if the nasal spray vaccine is not suitable for them.
Children who should have the flu vaccine injection
Children with long-term health conditions
Children with long-term health conditions, such as diabetes or heart problems, are at higher risk from flu.
It's important they're vaccinated.
Examples of long-term health conditions
Where to have the flu vaccine
| From 6 months until 2 years
(with long-term condition)
| From 2 years until child
starts primary school
|All children at primary school||School|
|All year 7 school children||School|
| Children aged 12 to 17 years
(with long-term condition)
| Home-schooled children
(aged 4 to 11 years)
Home-schooled children should be invited for vaccination by the local healthcare team. If you do not hear from them, ask your child's GP where they should go for vaccination.
If your school-aged child has a long-term health condition, you can ask the GP surgery to give the vaccine instead of having it at school.
What if my child is unwell on the day?
Your child should wait until they're better before having the nasal spray flu vaccine if they have:
- a very blocked or runny nose – these might stop the vaccine getting into their system
- a high temperature
How the nasal spray flu vaccine is given
The vaccine is given as a spray squirted up each nostril. It's quick and painless.
The vaccine will still work even if your child gets a runny nose, sneezes or blows their nose.
If your child is under 9 years old, has a long-term health condition and has never had a flu vaccine before, they'll be given 2 doses. These doses are given 4 weeks apart.
How effective is the nasal spray flu vaccine?
The nasal spray flu vaccine gives children the best protection against flu.
It may take around 2 weeks for the flu vaccine to work.
Any children who catch flu after vaccination are less likely to be seriously ill or be admitted to hospital.
Side effects of the children's flu vaccine
The nasal spray flu vaccine for children is very safe. Most side effects are mild and do not last long, such as:
- a runny or blocked nose
- a headache
- loss of appetite
If your child has the injected flu vaccine, side effects include:
- a sore arm where the injection was given
- a slightly raised temperature
- aching muscles
These side effects usually last for a day or two.

What's in the nasal spray flu vaccine
The nasal spray flu vaccine contains small amounts of weakened flu viruses. They do not cause flu in children.
As the main flu viruses can change each year, a new nasal spray vaccine has to be given each year.
The brand of nasal spray flu vaccine available in the UK is called Fluenz Tetra.
The nasal spray vaccine contains pork gelatine. If this is not suitable, speak to your child's nurse or doctor about your options.
You can find a full list of ingredients in the Fluenz Tetra patient information leaflet (PDF, 139kb).
