the flu vaccine is your best defence against the flu – and it helps reduce the spread to people around
you.1 Let’s untangle some of the myths and facts.

Let’s face it, the flu is never on anyone’s wish list.
For many people, the flu virus (or influenza) can feel like a bad cold – painful, grotty and an unwelcome
interruption to your life. It can cause symptoms like fever, aches and chills, a sore throat, headache, dry cough
and runny nose.1
But the flu can also cause more serious illness, with complications like pneumonia sometimes leading to
hospitalisation. In some cases, it can even be life-threatening.1
That’s why reducing the spread of the flu is essential – and experts say getting your flu shot each
is one of the best things you can do to help.
Why get the flu shot?
The COVID-19 pandemic has given us all a masterclass in reducing the spread of germs. These good hygiene practices
– hand washing, cleaning surfaces, staying home when sick – are also important for preventing the spread
of the flu.
But for the best protection against the flu, the Australian Government recommends the flu
vaccine.2 Experts say it lowers your risk of catching the virus, as well as preventing serious
illness if you do get infected.
By getting your flu shot, you can also help protect more vulnerable groups in the community. This includes people
are unable to get vaccinated, and those who are most at risk of serious illness, such as babies, people over 65,
pregnant women, Aboriginal and Torres Strait Islander people, and those with long-term medical conditions or
weakened immune systems.1
How does the flu shot work?
Like all vaccines, the flu shot works by training your body’s natural immune response.3
Essentially, it tricks your body into thinking it has been infected with the influenza virus, which prompts your
immune system to create antibodies to fight it off.
This means if you come into contact with the live flu virus in future, your body should be able to recognise it and
make antibodies quickly enough to protect you.
When should you get the flu shot?
The flu vaccine is updated each year to protect against the most common strains of influenza virus, which change
frequently. That’s why we're told it’s important to get the flu shot every year.
For the best protection, the Australian Government Department of Health recommends getting your flu shot in April
– before winter, the peak flu season, starts.4
Once you’re vaccinated, it takes about two weeks for protection to develop. While protection should generally
last the whole season, you’ll have the strongest defence against the flu for the first three to four months
after getting the shot.5
How does it work with the COVID-19 vaccine?
If you’re in the queue for the COVID-19 vaccine, you should also get the flu shot – but it's
to receive the vaccines at least 14 days apart, according to the Australian Technical Advisory Group on Immunisation
ATAGI advises that it doesn’t matter which one you have first, but it’s best to consult with a health
care professional to advise on your particular circumstances.
Can the flu vaccine make you sick?
One of the most common myths about the flu shot is that it can give you the flu. Experts tell us this is not
possible, because the flu vaccine doesn’t contain any active influenza virus, only parts of ‘dead’
(deactivated) virus that are not capable of causing influenza.7
However, we know that some people may develop mild symptoms like body aches, tiredness and low-grade fever soon
getting the flu shot. This is a common reaction to many vaccines.
Luckily, these side effects usually only last a day or two and should get better without treatment.1
For most people, the chance of serious side effects is very low. If you have any concerns, talk to your GP.
Experts say the flu shot is safe and effective, and getting vaccinated each year helps protect not just you, but
people around you too.
