Immunisation Calculator

The Immunisation Calculator is based on the Australian National Immunisation Program (NIP) for all Australian children prior to their 10th birthday. If vaccine doses are delayed or missed, the Calculator can provide a catch-up schedule.

Schedule variations for all states and territories have been incorporated.

Calculator recommendations are provided by antigens due. Users can access additional information to assist with interpretation of the recommendations in the ‘Help and Support’ pages.


'Understanding the Calculator recommendations' can be found under the Help and Support tab.

If the parent will not accept all antigens 'Due Immediately' at the first encounter, or does not present on the recommended future dates, a new calculation should be undertaken at each presentation.

Clinical assessment and judgement may be required for some complex or overseas catch-ups.

Providers are encouraged to access the online version of the Australian Immunisation Handbook as this contains the most up to date information.
