Flu vaccination

Influenza viruses change from year to year, forming new strains. 

In the Northern Territory (NT) there are more flu cases in March or April before the annual flu season in southern states. 

Therefore it is important to be vaccinated against influenza as early in the year as possible.

Being vaccinated yearly is recommended to protect you against the current influenza virus.

Who can get the free vaccine

You are eligible for a free influenza vaccine if you fit into any of the following groups:

  • everyone over 65 years old regardless of medical conditions
  • Indigenous children and adults:
    • all children over aged six months to five years
    • all people over 15 years
    • 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.

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

If you don't have access to a free vaccine but you want to be vaccinated you should contact your 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.
