## EHDSImmunisation to FHIR Immunization Mapping

# EHDSImmunisation → ImmunizationEuCore

**Ongoing alignment:**The models are expected to continue evolving, with updates incorporated into this Implementation Guide to maintain alignment with the EHDS Implementing Acts.

### EHDSImmunisation → ImmunizationEuCore

 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/1.0.0/StructureDefinition-EHDSImmunisation.html) 
*  **Target FHIR profile:** [ ImmunizationEuCore ](StructureDefinition-immunization-eu-core.md)

| Element | Relation | Resource | Element | Notes |
| header | related-to | Immunization | . | Dataset-level; not usually carried in Immunization as-is. |
| header.subject | equivalent | Immunization | patient |  |
| header.identifier | equivalent | Immunization | identifier | Copy over all identifiers if multiple. |
| header.author[x] | related-to | Immunization | performer | Immunization lacks a dedicated author participant. Usually, the performer is also the author; however in case the two participants shall be clearly distinguished, the performer.function element can be used for this purpose. |
| header.date | no-map | Immunization |  |  |
| header.status | equivalent | Immunization | status | Use`statusReason`in FHIR for "not done" reason when applicable. |
| header.source | equivalent | Immunization | extension:informationSource〔R4〕informationSource〔R5〕 |  |
| header.language | equivalent | Immunization | language |  |
| administrationTime | equivalent | Immunization | occurrence[x] | Usually`occurrenceDateTime`. |

| note | source-is-broader-than-target | Immunization | note.text | Map EHDS note to one or more Immunization notes where needed. |
