The Unified Nomenclature of Vaccines (NUVA) is both a multilingual catalog of vaccine names (vaccines marketed or that have been marketed in France or abroad, generic names used to designate certain vaccines in physical vaccination records) and a structured description of vaccines using the concept of valence. This helps define an ontology of vaccines.

Structuring vaccination information is necessary for interpreting vaccination history and for the interoperability of digital systems dealing with vaccine information.

Syadem provides with NUVA a unified reference for vaccines, enabling standardized terminology that facilitates communication and information exchange among healthcare professionals, researchers, and governments.

In France, this nomenclature is accessible on the multi-terminology server of the Digital Health Agency: https://smt.esante.gouv.fr/terminologie-nuva.
