Version (4.0.0) of the NICC includes catch-up recommendations for the following antigens:

• Diphtheria, Tetanus (dT).
• Diphtheria, Tetanus, Pertussis (DTPa, dTpa).

• Refinements to the medical at-risk conditions list, including but not limited to:
  • Inclusion of additional medical at-risk conditions (e.g. harmful use of alcohol, smoking), and condition specific catch-up recommendations.
  • Inclusion of additional sub-conditions (e.g. low birth baby and gestation period for a preterm infant).

Version 3.0.0

The new version (3.0.0) includes support for all children under the age of 10, including those who may have multiple medically at-risk conditions.

Health professionals can select multiple medical at-risk conditions a child may have. Of the nominated medical at-risk conditions, the NICC will pre-select a 'dominant' (sometimes referred to as the 'primary') condition using a combination of factors. Health professionals can generate a schedule for the 'dominant' condition.

Health professionals can override the selection if deemed necessary. Catch-up schedules for each of the nominated medical at-risk conditions can be generated, one at a time.

Please note that owing to the complexities with the catch-up rules, at this time, health professionals will not be able to select multiple immunocompromising conditions (say 'Haematological malignancies and 'HIV infection') and/or multiple solid organ transplants (say Heart and Lung transplant). Although less common for the under 10s cohort, we understand that this might be more common in the older cohorts. Future releases of the NICC will include support for these scenarios.

Other inclusions: 

• Removed question pertaining to 'international travel' on Step 1. Vaccination for international travel may be introduced in the future.
• Updates to the vaccines list to include newly registered vaccines such as Vaxelis.
• Minor refinements to the labels in use for the medical at-risk conditions.
• Incremental refinements to the user interface, and overall user experience.
• Upgrades to the technologies to improve performance, efficiency, and maintainability of the codebase.

Keep an eye on the Announcements page for updates to the NICC. Further information on upcoming (major) releases will be provided when they become available.
