Child vaccination

​Immunisation is a simple, safe and effective way to protect against harmful diseases.

Immunisation protects individuals and the community by reducing the spread of disease.


How it works

  • Immunisation uses the body'​s natural defence mechanism – the immune response – to build resistance to specific infections.
  • When a person is vaccinated, the body produces an immune response to fight the disease, but without the person experiencing symptoms of the disease.



  • When the level of immunisation in a community is sufficiently high, the risk of the disease spreading lowers. This communal, or herd, immunity can save countless lives.
  • Vaccinating a child reduces the opportunity for that child to pass on a disease, especially to young babies who are not yet fully immunised and persons in the community who are immunosupressed.
  • Vaccinating your child reduces their risk of the severity and complications of harmful diseases.
