HLN has released a new version of its open-source Immunization Calculation Engine (ICE), featuring updated vaccine logic for COVID-19, meningococcal B, pneumococcal, and yellow fever, along with a core service upgrade. Explore what is new and test the updated logic using CDS Insight.

HLN has released ICE v2.59.1, adding support for the routine 2026–2027 COVID-19 immunization recommendations issued by the American Academy of Pediatrics and the American Academy of Family Physicians, along with a new mRNA influenza vaccine. Building on existing influenza and RSV functionality, ICE now supports the medical societies’ evidence-based routine immunization recommendations for the 2026–2027 respiratory season.
