The following standards and related specifications were identified as the recommended approach to support the in-scope requirements. The table lists the summary with the rationale.
Standardization Requirement | Options | Choice | Rationale |
Messaging | FHIR Immunization | x | The FHIR Immunization Resource supports the use cases described above without further extension or localization. In the event that extension is required to support future requirements, FHIR provides a straightforward mechanism for creating extensions. Canada-specific terminology value sets can be used while remaining “FHIR conformant”, as the FHIR Immunization resource only specifies examples; implementers are free to use any value set they choose. FHIR has significant momentum among vendors and developers, meaning the long-term sustainability of FHIR-based implementations will likely be superior. There is a substantial ecosystem of open-source tools and reference implementations for FHIR that implementers can leverage to accelerate their projects. |

Terminology
| pan-Canadian Public Health Immunization Subsets (SNOMED-CT) | x | The pan-Canadian Public Health Immunization Subsets reflect Canadian requirements (e.g. Canadian vaccine lists), and is aligned with the PHAC Canadian Immunization Guide. It is being adopted in additional projects across Canada (including AB, SK, MB, Canadian Forces, CIHI), so additional implementations that adopt the Ontario standard will be well positioned for interoperability with these groups or organizations. |
