Children and flu

Annual vaccination is the best form of protection against the flu

The flu

In Australia, severe influenza or ‘the flu’ is the leading cause of hospitalisation for children under 5 and can sometimes be fatal.

The flu is a disease that is easily spread and mainly affects the upper airways and lungs.

The flu is not the same as a common cold and people with the flu may have symptoms that range from mild to moderate to severe.

Annual vaccination is the best protection

Vaccination is the best way to protect children from serious illnesses caused by vaccine preventable diseases. For more information and to keep up-to-date with recommended childhood vaccinations please visit the National Immunisation Program Schedule Queensland or call 13 HEALTH (13 43 25 84).

Compared with older children and adults, infants and children less than 5 years of age are more likely to get severe flu infections resulting in hospitalisation.

It is important for children under 5

The flu can cause serious illness in children, and sometimes involves visits to the emergency department or GP due to high fever, cough, pneumonia and seizures. While rare, severe complications such as encephalitis (life threatening brain inflammation) can also occur. Not only are flu infection rates high among children, they also contribute greatly to spreading the flu in the community.

Vaccinating young children protects the wider community by reducing the number of people with the flu virus. It also helps protect the people who are more vulnerable like very young children, older people and people with long-term medical conditions.

Signs and symptoms

  • fever
  • chills
  • body aches
  • headaches
  • sore throat
  • runny nose
  • cough
  • loss of appetite
  • lack of energy
  • diarrhoea
  • vomiting.

Symptoms usually start about 1 to 3 days after catching the flu and can last for a week or more. Some people can be mildly affected, while others can become seriously ill.If you experience flu like symptoms, please visit your GP or other health care provider.

How the flu spreads

The flu spreads:

  • when an infected person coughs or sneezes, and another person breathes it in.
  • through direct contact with fluid from an infected person’s coughs or sneezes.
  • by touching a surface with the flu virus on it, and then touching your mouth, eyes or nose.

How to stop the spread of the flu

The flu can spread easily through families, workplaces, childcare centres and schools. Practising good hygiene is your best defence against the spread of the flu.

To protect yourself and those around you here are 6 easy steps to help fight the flu:

  • Get a flu shot every year.
  • If you are unwell, stay at home and avoid contact with others.
  • Wash your hands often and properly with soap and water, or use an alcohol-based hand sanitiser.
  • Cover your cough and sneezes with a tissue or a flexed elbow. Throw your tissues away immediately.
  • Try to stay 1.5 meters away from anyone who coughs and sneezes.
  • Wipe down surfaces regularly with soap and water or detergent.


Why the flu vaccine is needed every year

Everyone should have a flu vaccine every year because flu strains constantly change. Flu viruses are quick-change artists. They can reproduce rapidly, mutate and exchange genes with each other. For these reasons there is a new flu vaccine every year to make sure you are protected from the current flu virus. Although the flu vaccine does not protect against COVID-19, it can reduce the severity and spread of influenza, which may make a person more susceptible to other respiratory illnesses like COVID-19.

Vaccinations are safe

The flu vaccine is safe and effective.

Vaccines given to children in Australia must pass rigorous testing before being registered for use by Australia’s Therapeutic Goods Administration (TGA). Even when the vaccine is registered for use, its safety continues to be monitored.

The best time for children to get the flu vaccine

The best time for a child to get the flu vaccine is prior to the flu season, if they are 6 months or older. Getting the vaccine from April will provide protection before the flu season, which is usually May to September, in Queensland. It generally takes 10 to 14 days to be fully protected after getting the vaccine.

Children aged 6 months to less than 9 years will require 2 doses of the vaccine at least 4 weeks apart the first time they are vaccinated against flu.

Possible side effects

Common side effects from the vaccine are usually mild and will pass within a few days. They may include redness or mild pain at the site of injection, muscle aches, fever, and headache.

Severe adverse reactions to the vaccine are very rare. If you need advice contact your GP or immunisation provider.

The difference between a cold and the flu

Colds and the flu are both viral respiratory illnesses, but they are caused by different viruses. Both these illnesses can have similar symptoms and at first it can be difficult to tell the difference.

In general, the symptoms of the flu are more severe and last longer than those of a cold. While colds usually pass in a few days, the flu can have life-threatening consequences.

Where to get the free flu vaccine

Free flu vaccines are available for children aged between 6 months to under 5, from GPs, community health clinics, Aboriginal Medical Services and other immunisation providers. Some GPs may charge a fee for consultation but the vaccine itself is free.

Although chemists may have flu vaccines, they are unable to give the vaccine to anyone under the age of 16.

Frequently asked questions

Children under 5 are being offered free vaccine because of all the vaccine-preventable diseases, influenza causes the most hospital admissions of children under 5 years of age.

Children 5 years of age and over are not eligible for free influenza vaccine but still benefit from vaccination, and it can be obtained under private prescription from your doctor

Febrile seizures (or convulsions) can be triggered by fever from any cause. A small number of children (2-4%) are susceptible to febrile seizures up until about six years of age. The seizures themselves usually last around one or two minutes and loss of consciousness is possible. Nearly all children who have a febrile seizure, regardless of the cause, will recover quickly without any ongoing effects or permanent neurological (brain) damage.

Influenza itself can cause fever which may result in febrile seizures. Febrile seizures related to fever after influenza vaccination are uncommon and occur in less than one in every 1,000 children who receive the vaccine.

Enhanced safety monitoring systems for influenza vaccines introduced in recent years, such as AusVaxSafety, have confirmed that influenza vaccine is safe in children under five years of age, with low rates of fever and medical attendance reported after vaccination.

Although influenza vaccines are grown in eggs, due to new vaccine manufacturing methods, the amount of material from the egg in the influenza vaccine is small (usually less than one microgram of egg protein per dose).

Recent studies have shown that people with egg allergy, including egg-induced anaphylaxis, have safely received the influenza vaccine.

Even though the risk of anaphylaxis or an adverse event is very low, if your child has this type of allergy you should seek advice about influenza vaccine from your healthcare provider, you may be advised to have your child vaccinated in a setting where immediate treatment for a possible reaction is available.

Yes. Childhood vaccines which are scheduled for children in the same months as the flu season, can safely be given to children at the same time. Speak to your doctor or vaccine provider about the best timing.

It takes 10-14 days to develop an immune response to the flu vaccine which means you are still able to catch the flu during that time, so have your flu vaccine before flu is widespread in your community.

There are also other viruses that circulate during winter months that can also cause similar flu like symptoms such as the common cold virus and respiratory syncytial virus (RSV) especially in the young and the elderly. Differences between cold and flu.

Everyone should have a flu vaccine every year because flu viruses constantly change. Flu viruses are quick-change artists. They reproduce rapidly, constantly mutate and exchange genes with each other. For these reasons there is a new flu vaccine every year.
