The Calculator collects and processes data provided by the user, validates the inputs, and generates and displays the output (i.e. catch-up schedule). 

Broadly, the catch-up calculator tool does the following:

  • Determines patient eligibility
  • Collects high-level patient information*
  • Collects vaccination history (if any provided)
  • Determines ‘validity’ of vaccines/antigens received (if any)
  • Generates catch-up schedule (as per catch-up rules provided)

A catch-up calculation is comprised four steps:

  • Step 1. Pre-calculation screening: In this step the calculator determines if it is suitable for the person needing the catch-up. The application user is presented with a few screening (or qualification) questions. It is mandatory to provide a response to each question. 
  • Step 2. Personal details: In this step the calculator collects necessary information about the person needing catch-up including name, date of birth, state of residence, etc. It is mandatory to provide a response to each question.
  • Step 3. Vaccination history: In this step the application user may provide the vaccination history for the person needing catch-up. Vaccination history can be provided in the form of vaccines or antigens administered. If no vaccines have been administered, this step can be skipped.  In this step the calculator also validates vaccines/antigens administered to date (if any). 
  • Step 4. Catch-up schedule: In this step the calculator generates a catch-up schedule based on predetermined catch-up rules and exceptions.
