This page is part of the WHO Digital Documentation of COVID-19 Certificates (DDCC) (v1.0.1: releases Draft) based on FHIR (HL7® FHIR® Standard) R4.

Logical Models
DDCC:VS Core Data Set
DDCC:TR Core Data Set

The recommended core data set in the WHO Digital Documentation of COVID-19 Certificates guidance is intended to include the critical data required for interoperability, specific to the scenarios of use defined and driven by the public health needs. A published version of the data dictionary is available in spreadsheet format in Web Annex A of the DDCC:Vaccination Status guidance and in an annex to the DDCC:Test Result guidance.

Logical Models

DDCC:Vaccination Status: Continuity of Care Core Data Set
DDCC:Vaccination Status: Proof of Vaccination Core Data Set
DDCC:Test Result Core Data Set, which includes Proof of Negative SARS-CoV-2 Test Result and Proof of Previous SARS-CoV-2 Infection.

DDCC:VS Core Data Set

The following table is an abbreviated copy of the DDCC:VS:Web Annex A, the published version of the DDCC:VS Core data dictionary with the following differences:

Date formats are updated to be compatible with FHIR (this means that dashes are required, e.g., YYYY-MM-DD, not YYYYMMDD),
Only SNOMED GPS mappings are included (columns SNOMED CT International was removed, but values are the same as SNOMED GPS)
It will include mappings to the HL7 FHIR elements used on the StructureDefinitions for the core data set. (forthcoming)
ICD-11 Comments/Considerations for vaccines refer back to source content and a related note for readability.
