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.



From 1 July 2017, a 2 dose Rotarix® schedule will replace the 3 dose RotaTeq® schedule in Western Australia, Victoria, Queensland and South Australia.

Rotarix® will be the only rotavirus vaccine used on the NIP in Australia for children commencing a schedule from 1 July 2017.

The Calculator will now recommend 2 doses of rotavirus vaccine for all children using the schedule, age limits and catch up criteria applicable for Rotarix® vaccine.

For children who have already received any dose of Rotateq®, providers should refer to their state specific transition information.

ATAGI clinical advice will assist immunisation providers during the transition period.
