Flu Vaccine: When Is the Best Time for Your Annual Shot?

Flu season can come around quickly, and getting vaccinated before winter is a practical way to help protect yourself, your family, and people in the community who may be at higher risk of severe illness.

In Australia, an annual flu vaccine is recommended for everyone aged 6 months and over. Because influenza viruses can change each year, the vaccine is updated regularly to help protect against the strains expected to be most common.

Why flu vaccination matters

For many people, the flu may cause fever, coughing, body aches, fatigue, and several days away from work, school, or normal activities. But for some people, influenza can lead to more serious complications.

Young children, older adults, pregnant women, Aboriginal and Torres Strait Islander people, and people with certain medical conditions may be more vulnerable to severe flu. Vaccination can help reduce the risk of serious illness and may also lower the chance of spreading influenza to others.

It is worth being clear: the flu vaccine does not guarantee you will not catch the flu. However, it can help reduce how severe the illness becomes and lower the risk of complications.

When should you get vaccinated?

In Australia, flu vaccination is usually recommended from April onwards, before flu activity tends to rise during winter. This timing helps ensure protection is strongest during the months when influenza is more likely to spread.

If you have not had your flu shot yet, it may still be worthwhile speaking with a GP or health professional. Flu can circulate outside the winter peak, so later vaccination may still provide protection.

Who may be eligible for a free flu vaccine?

Some people may be able to receive a free flu vaccine under the National Immunisation Program, including:

• Children aged 6 months to under 5 years
• People aged 65 years and over
• Pregnant women
• Aboriginal and Torres Strait Islander people aged 6 months and over
• People with certain medical conditions that increase their risk of severe flu

Eligibility can depend on your age, health history, and vaccine availability, so it is best to check with your doctor or local clinic.

What side effects are common?

Most side effects from the flu vaccine are mild and short-lived. These may include soreness where the injection was given, tiredness, mild fever, muscle aches, or redness and swelling at the injection site.

If you have had a severe reaction to a flu vaccine in the past, or if you have concerns about allergies, pregnancy, medications, or an existing medical condition, speak with a GP before getting vaccinated.

Other ways to reduce flu spread

Vaccination is helpful, but it works best alongside everyday prevention habits. Wash your hands regularly, cover coughs and sneezes, stay home when you are unwell, and avoid close contact with vulnerable people while you have symptoms.
