Overview

Defines how LOINC codes are used within HL7 v2 OBX segments for immunization data. This supports consistent representation of observations such as vaccine type, dose validity, and related attributes. It builds on existing HL7 v2 guidance rather than introducing new exchange patterns. Interest is ongoing as part of improving consistency and clarity in implementations.

Coming soon

Support for source material, diagrams, and supporting notes is coming in a future update.
