The Australian National Immunisation Program Schedule sets out the immunisations Australians are given at different stages in their life. The program aims to reduce the number of preventable disease cases in Australia by increasing national immunisation coverage. The program starts for an Australian when they are born. Vaccinations are given at birth, then again when the baby is 2 months, 4 months, 6 months, 12 months and 18 months. The immunisation schedule continues when the child is 4 years old, and then into adolescent years. The program is not compulsory and parents have the choice if they want their child vaccinated.
