Childhood flu vaccination helps protect children from flu and its complications, and children from 6 months old can have a flu jab given as a quick injection. At LIPS Healthcare, Battersea Power Station, children aged 6 months and over can have the trivalent flu injection, which is in stock this season. Below, we explain why the flu jab matters for children, how the trivalent vaccine works, what happens at the appointment and which side effects to look out for.

TABLE OF CONTENTS
Why is childhood flu vaccination important?
Childhood flu vaccination is important because flu can make young children very unwell, and children also pass flu easily to brothers and sisters, classmates and older relatives.
Flu is not just a bad cold. In young children it can cause a high temperature, aching and exhaustion, and some children develop complications such as a chest infection. Children with long-term health conditions, such as asthma or a heart condition, are more likely to become seriously unwell.

Flu viruses change from year to year, so the vaccine is updated every season. That is why children need a flu jab each autumn, not just once. You can read more in the NHS guidance on the children's flu vaccine.
What is the trivalent flu jab for children?
The trivalent flu jab is an inactivated flu vaccine that protects against the three flu strains expected to circulate this season, and it is given as a single injection.

"Trivalent" simply means the vaccine covers three strains of flu. Because the vaccine is inactivated, it contains no live virus and cannot give your child flu. The strains included are chosen each year based on international surveillance, as set out in the UKHSA Green Book.
Some families avoid pork products for religious or personal reasons. If that applies to you, ask about the vaccine ingredients when you book, and the clinician will confirm them before your child has the jab.
Protect your child this flu season. Book a children's flu jab for ages 6 months and over at LIPS Healthcare, Battersea Power Station.
Which children can have the flu injection?
Children from 6 months old can have the trivalent flu injection, including children with long-term health conditions such as asthma, diabetes or heart problems.

Before giving the vaccine, a GMC-registered clinician will check your child's health and confirm whether the vaccine is suitable. If your child has a complex health condition, the LIPS Paediatrics team can advise alongside your GP. Let the clinician know if your child:
- has had a serious allergic reaction to a flu vaccine or any of its ingredients
- has a severe egg allergy, so the clinician can confirm the vaccine is suitable
- has a high temperature or is unwell on the day
- has a condition or takes a treatment that affects the immune system
Children under 9 who have never had a flu vaccine before may need a second dose at least four weeks after the first. Your clinician will tell you whether this applies. If your child is poorly on the day, ask the clinician whether it is fine to go ahead.
What happens at your child's flu jab appointment?
A children's flu jab appointment is quick: the clinician checks your child's health, gives one injection and may ask you to wait for a few minutes afterwards.
- The clinician asks about your child's health, allergies and any previous vaccines.
- You hold or sit with your child to help them feel secure.
- The injection is given into the thigh for babies and young toddlers, or the upper arm for older children.
- You may be asked to wait briefly before leaving.
- If a second dose is needed, you can book it before you go.

A few small things help nervous children. Be honest that it will feel like a quick scratch, bring a favourite toy, and plan a treat for afterwards. Most children are back to normal within minutes.
LIPS Healthcare is on the first floor of Turbine Hall B at Battersea Power Station, easy to reach by the Northern line or the London Overground. If you live in Clapham, Wandsworth or Nine Elms, the clinic is a short journey for an after-school or weekend appointment.
Children's flu vaccine side effects
The most common children's flu vaccine side effects are a sore, red or swollen injection site, a mild temperature, irritability and tiredness, and these usually pass within a day or two.
Serious allergic reactions are rare. They usually happen within minutes of vaccination, which is why clinicians watch for any signs straight afterwards and are trained to respond.

If your child seems more unwell than you would expect, has a high temperature that does not settle, or you are worried for any reason, speak to a doctor. Families from Chelsea, Pimlico and Vauxhall can see a GP at LIPS, and for a problem that needs attention the same day but is not an emergency, the LIPS Urgent Care Centre can see your child.
