Influenza is more than a common cold. Influenza vaccine helps reduce the risk of influenza illness and complications. Current advice may vary by season, age, risk group, vaccine availability, and local guidance, so confirm with your paediatrician.

What is influenza vaccine?

Influenza vaccine helps the immune system recognise influenza viruses. It is especially important to discuss for young children and for children with chronic lung, heart, kidney, liver or metabolic disease, immunocompromise, or household risk situations.

What flu can look like

  • Sudden fever, cough, sore throat, runny nose, body ache, headache, and tiredness.
  • Some children may have vomiting or diarrhoea.
  • Flu can worsen asthma or wheeze and may cause pneumonia.
  • Young children can become dehydrated or very tired.

Prevention approach

  • Ask your paediatrician whether your child should receive flu vaccine this season.
  • Children with asthma, wheeze, or chronic disease should have their preventive plan reviewed before flu season.
  • Continue routine hygiene: handwashing, cough etiquette, and avoiding close contact when febrile.
  • Do not use antibiotics for flu unless a bacterial complication is diagnosed and treatment is prescribed.

Red flags / when to seek medical review

Seek urgent assessment if any of these occur:
  • Fast or difficult breathing, chest indrawing, blue lips, severe lethargy, dehydration, or persistent vomiting.
  • Fever with worsening cough or chest pain.
  • Child with chronic disease who develops flu-like illness.
  • Any infant or child who appears seriously unwell.

Important facts for parents

  • The flu vaccine cannot give a child influenza illness from the vaccine itself.
  • Mild fever, aches, or injection-site pain can occur after vaccination.
  • Flu vaccine does not prevent every cold; it targets influenza.
  • Annual advice may vary, so confirm the current recommendation locally.
  • This guide does not provide a fixed age or dose schedule.
