Current News

  • Upcoming Release of ICE (Early September 2021)
    • COVID-19 Update:
      • As always, HLN is actively monitoring all news and updates in regards to new and existing COVID-19 vaccines.  Currently, we are working on adding additional support and logic in ICE to handle the following:
        • COVID-19 Additional Dose - a  a dose administered when the immune response to a standard primary vaccine series is likely not to be protective. 
          • Note - “booster” dose of A “booster” dose of vaccine is a dose administered to restore protection after the effectiveness of protection from the primary series has declined. ACIP  ACIP does not recommend booster doses at this time. 
        • COVID-19 Vaccines Not Authorized by FDA, but Authorized by WHO
          • Note - The current release of ICE, Version 1.29.1 supports the handling of one COVID-19 vaccine that falls under this category - AstraZeneca COVID-19 vaccine (CVX 210). 
        • COVID-19 Vaccines Not Authorized by the FDA or WHO
    • Live Virus Bug Fix:

      • Fix bug where, in certain circumstances, ICE is incorrectly recommending Varicella or MMR 28 days later rather than on the same day.

  • ICE Plans for COVID-19 Implementation
    • HLN is actively monitoring all news and updates in regards to new and existing COVID-19 vaccines.  
    • Once a vaccine has been approved for use by FDA (either Expanded Access, EUA, or full licensure), ACIP will hold an emergency meeting and publish recommendations in a very quick timeframe (i.e. days). HLN intends to release a version of ICE that includes COVID-19 forecasting as early as possible after ACIP has published the guidelines. This initial release will contain COVID-19 logic known at the time of the release. As additional, actionable information on COVID-19 forecasting becomes available from official sources, HLN will continue to release additional versions of ICE, at appropriate times to reflect ongoing updates.
    • If you have any questions, comments or suggestions, please e-mail us at ice@hln.com.


  • The Importance of Upgrading After Each ICE Release
    • With each new release, we strongly recommend that all users and service providers update their running instances of ICE as soon as possible to the latest version. Each new release contains important forecaster business logic updates and bug fixes.


  • ICE Code Systems and Codes Now Available in Google Sheets
    • The ICE code systems and codes are now accessible in Google Sheets as an added convenience. These are the codes as those in the Implementation Guide. The codes will continue be updated in both the places.
    • The Google Sheet is available here.


  • Configuration Note
    • As of release 1.24.1, the ICE service is configured with the output_supplemental_text option in the properties file set to enabled by default.
    • As of release 1.16.1, the ICE service is configured by default to return the earliest and overdue dates in addition to the recommendation date. In prior releases, the default configuration was to return only the recommendation date for the forecast.
      • If your application has not been configured to display the earliest and/or overdue dates, we recommend turning this feature off by changing the output_earliest_and_overdue_dates value in the ice.properties file to "N". Failure to do so may result in incorrect interpretation of the recommendation date. 
      • If you are interested in returning the earliest date or overdue date, please refer to the latest ICE Implementation Guide for details indicating precisely where each of the forecast dates – earliest, recommended, and overdue – are specified in the ICE output, and under what circumstances.
