Understand the problem
Codes are created for different purposes and change over time, while vaccination histories must remain useful for a lifetime.
Technical knowledge for immunization coding
IVC brings vaccine code-set authors and terminology experts together to share practical knowledge, examine difficult questions, and develop useful technical resources.
Why this work matters
Vaccine vocabularies allow immunization systems to record which vaccines were given and preserve that meaning as records move between systems, organizations, and countries.
Codes are created for different purposes and change over time, while vaccination histories must remain useful for a lifetime.
IVC gives code-set authors and other specialists a practical place to compare experience and work through hard questions.
NUVA, alignment work, articles, and meeting presentations turn discussion into knowledge that others can use.
A shared technical foundation
NUVA—the Unified Nomenclature of Vaccines—is an open, shared ontology for representing administered vaccines and their valences consistently across existing vaccine code systems and over time.
It does not replace national, regulatory, product, billing, or clinical code systems. It provides a shared model that can help people interpret and relate them.

Monthly peer meetings are the clearest way to learn what others are working on, bring a technical question, or share your own experience.
