On February 17, 2024, HLN released a new version of the Immunization Calculation Engine (ICE), with support for updated COVID-19 vaccine recommendations. ICE is a state-of-the-art open source software system that provides clinical decision support for immunizations for use in Immunization Information Systems (IIS), Electronic Health Record (EHR), and Personal Health Record (PHR) Systems.
Version 2.45.2 includes the following updates:
- COVID-19: Added support for the 23-24 season additional dose for patients 65 years and older. Added support for the 24-25 season recommendations, including the additional dose for patients 65 years and older. Several updates to ensure alignment with the latest vaccine administration guidance.
- Hepatitis B: Series selection implementation updates to ensure the appropriate series is selected in certain circumstances.
- Hib: Added CVX 132 to the implementation files for the Hib 4-dose Series.
- RSV: Updated the display name for CVX 307 in the configuration files. Updated the rules to support validation of infant RSV CVX codes starting on 8/3/2023 and to support validation of adult and otherwise unspecified RSV CVX codes starting on 6/21/2023. Updated the supplemental text to remove special characters (apostrophe and en dash).
- Zoster: Updated the implementation of the minimum interval between a CVX 121 or CVX 188 to a CVX 187 to 56 days rather than 28 days.
- Other: Addressed an issue with supplemental text, where, in some circumstances, supplemental text associated with one vaccine group appeared in the forecast output for a different vaccine group.
The ICE Implementation Guide Codes sheet has been updated to reflect the changes in the RSV supplemental text. Please see the Release Notes for additional details.
Forthcoming ICE releases: Upcoming ICE releases will address changes in the Pneumococcal and Meningococcal B vaccine groups, including the updated dosing schedule for MenB-4C (Bexsero).
