How to use the National Immunisation Catch-up Calculator (NICC)
The National Immunisation Catch-up Calculator (NICC) can provide a catch-up schedule for people who have missed any National Immunisation Program (NIP) vaccine doses, or if any vaccine dose has been delayed.
Who is the NICC for?
This current version (2.0.0) of the NICC includes catch-up information for all healthy children under 10 years of age, including additional recommendations for Aboriginal or Torres Strait Islander children in South Australia, Western Australia, Queensland and the Northern Territory, and children medically at risk.
Users should always exercise their own independent skill or judgment, or seek additional professional advice before relying on the information provided for clinical decision making.
Who isn’t the NICC suited to?
Currently, the NICC cannot be used for children over 10 years old, or for adolescents or adults. See Future updates for more information.
The NICC is based on the Australian NIP schedule. Vaccines administered overseas must be translated using foreign language terms. Vaccines administered overseas, not included in the Australian NIP schedule, will be excluded from the calculations.
This version of the NICC provides recommendations for one medically at-risk condition at a time. The ability to generate catch-up schedules for children under 10 years of age with multiple at-risk conditions will be released in the future. See Future updates for more information.
The NICC will be expanded to support children and adolescents under 20 years of age in the future. See Future updates for more information.
How are the calculations made?
The catch-up calculation involves 4 steps:
- Pre-calculation screening to determine eligibility: The NICC determines if it can be used for the person needing the catch-up. The user is asked 3 screening questions and the date of birth of the person needing catch-up. You must answer each question to proceed. You can also download the business rules which are used to generate the schedule.
- Personal details: The NICC collects necessary information about the person needing catch-up, such as name, date of birth, state or territory of residence, and at-risk condition. You must answer each question to proceed.
- Vaccination history: Here, you enter the vaccination history for the person needing catch-up. Vaccination history can be provided in the form of vaccines or antigens administered. Vaccines administered overseas must be translated using foreign language terms. If no vaccines have been administered, this step can be skipped. In this step, the NICC also validates any vaccines or antigens administered to date.
- Catch-up schedule: The NICC generates a catch-up schedule based on predetermined catch-up rules and exceptions. The schedule can be exported as a PDF.
NICC recommendations are based on antigens required, not vaccines. If you need help interpreting the NICC’s recommendations, see the Australian Immunisation Handbook’s Catch-up vaccination and Resources.
Future versions of the NICC aim to expand the age groups for catch-up calculations. Further information on upcoming releases will be provided when they become available.
