Influenza Vaccination

Influenza Vaccination - What it is

What is flu?
"Influenza", commonly known as "flu", is a highly contagious disease with symptoms such as fever, cough, runny nose, sore throat, chills, joint and muscle pain, stomach symptoms, headache and extreme tiredness. It is caused by a virus that spreads mainly by coughing, sneezing and close contact. The virus can also be spread indirectly when your child touches a surface with flu virus on it (for example, a toy) and touches his or her nose or mouth.

Why vaccinate?
Flu is usually worse than the common cold. Your child may spend a few days in bed recovering. It can lead to life threatening complications such as pneumonia, myocarditis (inflammation of the heart) and encephalitis (inflammation of the brain). Other associated complications include bronchitis, sinusitis and middle ear infection. 

Who is more likely to develop complications from flu?
  • Children who are six months to five years old, with no underlying medical condition.
  • Patients with long-term medical conditions such as:
    • Chronic lung conditions such as asthma or chronic lung disease
    • Chronic heart disease
    • Neurologic and neurodevelopmental conditions with muscle weakness, swallowing and breathing problems
    • Diabetes
    • Chronic kidney or liver conditions
    • Blood disorders such as thalassaemia
    • Immune system disorders
    • Extreme obesity
  • Children on long-term aspirin therapy
  • Pregnant women

Does flu vaccine protect against all types of flu?
Flu vaccine does not protect against all other viruses that cause flu-like symptoms or the common cold. It is still important to maintain good personal hygiene habits such as sneezing or coughing into a tissue and disposing of them correctly, avoiding contact with sick people, wearing a mask and self-isolation when unwell, keeping your hands away from your eyes, nose and mouth, and washing hands regularly with soap and water, especially after going to the toilet and before eating.
