Winter is here — and so are the germs

As we head into winter, we start to see the usual spike in respiratory illness in babies and children.

Coughs. Fevers. Runny noses.And the constant question: is this just a cold… or something more?

For most families, it’s not just the illness that’s challenging —it’s the uncertainty that comes with it.

One of the most common questions I get asked every year is about the flu vaccine — when to get it, who needs it, and whether it’s actually worth it.

So let’s break it down simply.


The flu vaccine — do we need it? When? Is it worth it?

In Australia, babies and children can receive the flu vaccine from 6 months of age.

For babies younger than this, protection relies on vaccination during pregnancy and the immunity of those around them.

Timing-wise, the aim is to have protection on board before winter really sets in, as immunity is strongest in the first few months after vaccination.

But if you’ve missed that window? It’s still absolutely worth getting.


Why it’s recommended (even if it’s not perfect)

The flu vaccine is updated each year based on the strains expected to circulate.

It doesn’t cover every possible strain — and that’s often where confusion comes in.

But here’s what matters:

It’s not just about preventing illness. It’s about reducing how sick your child gets.

Even when it’s not a perfect match, it can:

  • Reduce severity of illness

  • Lower the risk of hospitalisation

  • Help the immune system respond more effectively

And in young children — particularly those under 5 — that can make a significant difference.


What about safety?

This is understandably one of the biggest concerns for parents.

The flu vaccine has been used for many years and has a strong safety profile in children.

Most side effects are mild and short-lived, such as:

  • A sore arm

  • Mild fever

  • Tiredness or irritability

These usually settle quickly.

Serious reactions are very rare.


The flu vaccine can also be given at the same time as routine childhood immunisations and is safe during pregnancy and breastfeeding.

Even children with egg allergy can usually receive it safely.


A few practical things to know

  • Some children receiving the flu vaccine for the first time may need two doses to build stronger immunity

  • In Australia, it is free for children aged 6 months to under 5 years

  • Most children receive the injection, although nasal options may be available in some settings

  • The simplest approach for families is to have everyone vaccinated around the same time


The Sick Sense take

Winter illness is part of childhood.

You can’t avoid every virus. You can’t control every exposure.

But you can reduce risk. You can recognise when things are escalating.And you can know what to do next.

The flu vaccine is one piece of that.

Because when something happens —you don’t rise to the occasion.

You fall back on what you know.

And that’s where your Sick Sense comes in 🤍
