## EHDSImmunisation to FHIR Immunization Mapping

# EHDSImmunisation → Immunization

**Ongoing alignment:**The Xt-EHR logical models are under active revision and continuous refinement. Updates from Xt-EHR will be progressively incorporated into this Implementation Guide to maintain alignment with the evolving EHDS specifications.

**Yellow row/cells:**In this ballot publication, some row/cells of the mapping table have been left in yellow to indicate areas requiring further review or refinement; including feedback from the Xt-EHR joint action (see note above). These highlights will be addressed in subsequent updates to ensure accuracy and completeness of the mappings.

### EHDSImmunisation → Immunization

 This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR ImmunizationEuCore profile used by this Implementation Guide. 

**Mapping Context**
*  **Source logical model:** [ EHDSImmunisation ](https://www.xt-ehr.eu/fhir/models/0.3.0/StructureDefinition-EHDSImmunisation.html) 
*  **Target FHIR profile:** [ ImmunizationEuCore ](StructureDefinition-immunization-eu-core.md)
