Initial Release of the NIST Immunization Test Suite Edition 2

[Rob Snelick]

NIST is pleased to announce the initial release of the Immunization Test Suite Edition 2. This new tool complements the existing Immunization Test Suite, which will remain available for use. Users can choose to continue using the existing tool or migrate to Edition 2 depending on their needs. The tool targets the Assistant Secretary for Technology Policy (ASTP)/Office of the National Coordinator (ONC) for Health IT Standards Version Advancement Process (SVAP) for the § 170.315(f)(1) Transmission to immunization registries criterion.

The requirements for Edition 2 are based on the HL7 Version 2.5.1 Implementation Guide for Immunization Messaging 2.5.1 (updated in 2018), also known as the consolidated Implementation Guide, and the NIST Errata and Clarification Guidelines document (July 2025). The latter document captures errata and clarifications identified during the development of the tool. Furthermore, Edition 2 incorporates select American Immunization Registry Association (AIRA) Technical Advisory Bulletins (TABs).

The NIST Immunization Test Suite Edition 2 provides validation improvements, profile viewer enhancements, support for dynamic value sets, and other general improvements. For a comprehensive list of feature enhancements and tool details, please refer to the Release Notes under the documentation tab.
