Influenza viruses change from year to year, forming new strains.
Being vaccinated yearly is recommended to protect you against the current influenza virus.

You are eligible for a free influenza vaccine if you fit into any of the following groups:
- anyone aged 65 years or older, regardless of medical conditions
- all children aged six months to under five years
- all Aboriginal people aged six months and over
- anyone aged six months and over with a medical condition that may increase their risk of severe influenza infection
- pregnant women at any stage of pregnancy - the vaccine protects the baby in the first six months of life.
Medical conditions that may increase your risk of severe influenza infection include:
Heart conditions including any of the following:
- rheumatic heart disease
- cyanotic congenital heart disease
- coronary artery disease
- congestive cardiac failure.
Chronic lung / breathing problems including any of the following:

If you have a medical condition not listed above, ask your health care provider if you are eligible to get the free seasonal influenza vaccine.
Your workplace may also offer you a free flu vaccination. Ask your employer for more information.
Where to get the free vaccine
Go to find a community care centre to see where you can get your free vaccination.
You can also get your free vaccine at an Aboriginal Medical Services clinic or a remote health centre.
Some general practitioners (GPs) offer free seasonal influenza vaccines to eligible risk groups, but they may charge a consultation fee.
Other people who should be vaccinated
Anyone aged 6 months or older who is not eligible for a free vaccine and would like to be vaccinated should contact their GP or health centre for a prescription.
About the vaccination
The vaccine takes about two weeks to work and will last for about 12 months. For ongoing protection you should get a new vaccine each year.
You can't catch influenza from having the vaccine as it does not contain any live influenza virus. Because it takes two weeks for the body to be fully protected, if you have contact with someone with influenza during this time you may still become sick.
If you have had the flu in the past you will be protected against one strain of flu, but not the other strains found in the vaccine. So the influenza vaccine is recommended every year to protect you against the strains causing infections that year.
