On 16 June 2026, EUVAC presented its latest implementation progress at the 36th meeting of the eHealth Member State Expert Group.

The progress update was delivered by EUVAC Project Coordinator Sofia Terzi of IDIKA SMSA, together with contributions from Marcello Melgara of UCSC as co-leader of the project’s technical work package.

The presentation demonstrated how EUVAC is progressing from service definition and architecture towards implementation, integration, testing and pilot deployment.

A major achievement is the positioning of Vaccination History as a standalone MyHealth@EU document and service. Rather than functioning as an optional section of the Patient Summary or Hospital Discharge Report, Vaccination History will have a clearly defined purpose, minimum dataset and implementation pathway.

The update covered progress in four main areas.

Functional requirements and architecture

The project has developed the functional requirements, workflows and architecture required to support the Vaccination History service. The implementation will reuse established MyHealth@EU exchange patterns while introducing the components needed for structured FHIR vaccination information, document rendering and OpenNCP support.

Work is continuing on the operation-ready specifications, terminology bindings and division of responsibilities between central MyHealth@EU services, EUVAC and the participating pilot countries.

Testing, legal compliance and data protection

EUVAC has established a staged testing approach. The clinical cross-border retrieval scenario will follow the formal MyHealth@EU testing framework, while additional citizen-mediated and proof-of-concept scenarios will be assessed through demonstrators and pilot evidence.

Testing will address FHIR structure, terminology, document rendering, required data fields, identity and consent checks, provenance, traceability and auditability.

GDPR principles, particularly data minimisation and purpose limitation, remain central to the service design.

Trust and verification

The project is developing a trust-anchor design that covers both established online exchange through MyHealth@EU and the portable presentation of vaccination information.

For cross-border clinical retrieval, the service will use the existing MyHealth@EU trust path. For citizen-mediated access and portable presentation, EUVAC is examining how a vaccination artefact could be signed, stored or presented through a wallet or QR-based solution and verified by an authorised party.

Implementation and pilot preparation

EUVAC is now working to assemble the implementation package, including technical components, validators and rendering tools. This will be followed by integration and scrutiny testing and, subsequently, evidence collection from pilot operations.

The presentation also provided an early preview of the EUVAC mobile application and healthcare-professional interface concepts.

The update to the eHMSEG marked an important step towards an operational Vaccination History service that can support secure clinical access, citizen-mediated presentation and future European Digital Vaccination Card scenarios.
