The ICE Vision

ICE and its related products are continually being maintained and enhanced. HLN is committed to improvements that allow us to fulfill our vision for these products, including:

  • Adherence to appropriate clinical guidelines (ACIP) 
  • Standards-based technical architecture and application programming interface (API)
  • Support for a growing range of relevant APIs for invoking and receiving responses from the ICE service, making it easy to integrate ICE with a wide variety of other systems
  • High performance and high scalability
  • Published knowledge base, including complete documentation of the ICE immunization schedule, ICE installation process, and ICE API(s)
  • Available under a standard permissive Open Source license
  • Use within both public sector and private sector systems
  • Tools that allow self-administration where practical
