Influenza vaccine for children

To protect your child

The flu is a viral infection that can be serious and sometimes life-threatening – it's not the same as having a bad cold. Even if your child is fit and healthy, they can catch the flu. The flu vaccine can help stop your child from getting very sick and needing hospital care.

Flu vaccination is especially important for children with certain long-term (chronic) health conditions, such as asthma, heart disease or diabetes. This is because these children are most likely to develop complications from the flu (eg, chest infections). If your child has a long-term condition, make sure they have their flu vaccination every year before winter starts. All household members should also be vaccinated to reduce the chances of your child being exposed to the flu.

To protect your family/whānau

The flu virus is very easy to catch and can affect anyone. It spreads through the air by coughing and sneezing, as well as by virus particles found on hands, cups and other objects that have been in contact with an infected person's mouth or nose. Many people don’t know they have the flu as they don't feel ill. But they can still pass it on and make other people very sick. Young children, babies, pregnant women and older people are more likely to get sick with the flu.

Giving your child the flu vaccine may not stop them getting the flu, but it should stop them getting very sick and prevent them needing hospital care. It takes up to 2 weeks after getting the flu vaccine for your child to have protection against the flu.

Funded and unfunded vaccines can be given by your doctor, nurse, midwife and some paramedics and pharmacists who have been trained as vaccinators.

Different providers may have restrictions on what vaccinations can be given or the ages of people they can administer these to. So it’s worth checking with the provider first to see if you or your whānau can get the vaccination needed from them.

Funded and unfunded flu vaccines are available in many different settings. These include medical or health centres, pharmacies, community-based clinics including marae-based clinics, mobile health clinics and mobile vaccination services.

Do I need to pay for the flu vaccine?

If your child doesn't meet the free flu vaccine criteria there will be a cost for the flu vaccine. Ask your healthcare provider if you’re not sure.

If you're not eligible for a free flu vaccine, it can cost between $25 and $45.

• Children 6 months to under 9 years: Talk to your vaccinator – if it's your child's first flu vaccine, they'll need 2 vaccinations (at least 4 weeks apart). This is because they may not have any immunity to the flu. It they've had a flu vaccine before, they'll only need 1 dose. 
• Children 9 years of age or older only need 1 dose. 

The following flu vaccines will be available for children in 2025:

• Influvac Tetra: For pēpi and children 6 months of age and older. It's funded for those who are eligible. Read more about the free flu vaccine eligibility criteria(external link).
• Flucelvax Quad and Fluquadri: For pēpi and children 6 months of age and older (there's a cost involved as it's not funded)
• Afluria Quad: For children 3 years of age and older (there's a cost involved as it's not funded).

For more detailed information on each vaccine, including the ingredients, read the Medsafe Consumer Information in the more information section below.

Your child can't catch the flu from a flu vaccination as there's no live virus in the flu vaccine. 

Can a flu vaccination make my child sick?

Most people have no reaction or a mild reaction to a flu vaccination. After the vaccination, your child may have:

• soreness, redness or swelling where the vaccine was given
• fever
• aches.

These are usually mild and only last 1 or 2 days.

Read more about medicines and side effects and reporting a reaction that you think might be a side effect.

• You don't need to give babies and children paracetamol before or after the flu vaccination. 
• If your child develops a fever after their vaccination, use a cool cloth to wipe their face, hands and neck and keep your child in lightweight clothing and bedding, eg, a singlet and pants and covered by a sheet.
• Give plenty of breastfeeds or cool drinks. Read more about fever in children. 
• If your child is miserable because of the fever, you can give them paracetamol to make them more comfortable. Read more about paracetamol for children and use our paracetamol dose calculator to make sure they get the right amount.

Vaccination is not 100% effective for all people, so some vaccinated people may still get the flu. If they do, the symptoms are usually milder than they would be if they hadn't had a flu vaccination.
