Thinking about getting your child the flu vaccine? Here’s what you need to know

Why should I vaccinate my child? 

Young children catch and spread the flu more than any other age group. Thousands of children are hospitalised every year; hospitalisation rates in children are much greater than in older people.

Being hospitalised is just the tip of the flu iceberg: many children will need emergency department or GP visits due to a high fever, cough, pneumonia and convulsions. Rare but severe complications such as encephalitis (life threatening brain inflammation) can also occur, and mostly in healthy children.

Vaccination is the most effective way to prevent flu. Those vaccinated are  less likely to catch the virus and develop serious complications compared with those who are unvaccinated. The risk of flu is reduced, on average, by 50-60% in children receiving the vaccine.

Childhood flu vaccination programs have been shown to also protect others in the household and the community by 22-60%. This is called “herd” or “community” immunity and particularly helps protect vulnerable people who may be at risk of becoming seriously ill with the flu.

The influenza virus continually mutates, seeking to evade the immune system. Even if you have had flu infection in the past, antibodies generated from that infection may not recognise and fight off a recently mutated virus.

Is it safe?

Childhood influenza vaccination was temporarily suspended in 2010 after an unexpectedly large number of children had high fevers. Some children also suffered seizures.

These events were due to a single of brand of vaccine, which was withdrawn from use in this age group and is no longer produced. All flu vaccines now used in children have extensive clinical trial data demonstrating their safety.

These events have been a catalyst for major changes in Australia’s approach to monitoring safety once vaccines are registered for use. Vaccine safety and side-effects are now tracked continuously through the  AusVaxSafety program.

How do I vaccinate my child? 

Flu vaccines are expected to be widely available from mid April or early May. They are available at your GP surgery, community clinic and pharmacy, depending on your age and state or territory program.

Children aged under nine years who have not been vaccinated before require two doses in their first year. In young children previously vaccinated, only one dose is required.

Children less than six months are not recommended to receive the influenza vaccine: the most effective way to protect those too young to be vaccinated is by vaccinating mothers during pregnancy.
