Flu vaccination — the questions our patients ask
When should I get my flu shot?
The flu vaccine is best given between April and June in Australia, before flu season peaks. However, it's not too late if you missed that window — flu can circulate well into spring, so any time during the season is better than not at all. Annual vaccination is required because the influenza virus mutates each year and the vaccine is reformulated to match.
Why a new flu shot every year?
Two reasons. First, your immunity from last year's vaccine wanes over 6–12 months. Second, the virus itself changes — each year the World Health Organization recommends an updated formulation based on the strains circulating globally. The 2026 Australian flu vaccine targets four strains: two influenza A subtypes and two influenza B lineages.
Is the flu vaccine safe?
Yes — the influenza vaccine is one of the most studied and safest vaccines available. Side effects are typically mild: a sore arm for 1–2 days, occasional low-grade fever or fatigue. Serious reactions are very rare. The vaccine cannot give you the flu — it doesn't contain live virus (the standard injection is inactivated; FluMist contains a weakened virus that cannot cause illness in healthy individuals).
Can I get the flu shot with my COVID-19 vaccine?
Yes. The Australian Technical Advisory Group on Immunisation (ATAGI) confirms that the flu vaccine and COVID-19 vaccines can safely be co-administered (given on the same day). We can do both in one visit if you're due.
Who shouldn't get FluMist?
FluMist is not suitable for pregnant women, immunocompromised individuals, those on certain medications (like aspirin therapy in children), or people with severe asthma. Our doctors will assess suitability before giving it.
What about babies under 6 months?
Flu vaccine is not licensed for babies under 6 months. The best protection for very young infants is to ensure that everyone around them — parents, siblings, grandparents, carers — is vaccinated. This is called "cocooning" and it works.
How much does it cost if I'm not eligible for the NIP?
For patients not eligible under the NIP, the cost of the flu vaccine itself is $15 (or $50 for FluMist nasal spray) — the GP consultation remains bulk-billed.
