On December 22, 2021, HLN released a new version (v1.33.1) of the Immunization Calculation Engine (ICE) in support of updates to the COVID-19 vaccine.

    • Booster Dose Minimum Age has been updated to 16 years to support new CDC recommendation that 16-17 year olds “may” receive a Pfizer booster.

This release includes an important security update. We strongly recommend that all users and service providers update their running instances of ICE to version 1.33.1 as soon as possible. Each new release of ICE contains important forecaster logic updates and bug fixes.

Plans for COVID-19 Support in ICE

Once a vaccine has been approved for use by the FDA (either Expanded Access, EUA, or full licensure), the Advisory Committee on Immunization Practices (ACIP) will hold an emergency meeting and publish recommendations in a very quick time frame (i.e., days). HLN intends to release a version of ICE that includes updated COVID-19 forecasting as early as possible. The initial release will contain COVID-19 logic that is known at the time of the release. As additional, relevant information on COVID-19 becomes available from official sources, HLN will continue to release additional versions of ICE, at appropriate times.
