The current pages form the SNOMED CT Content Development Canadian Editorial Guidelines for Immunization.
The September 2020 release of the Canadian Edition of SNOMED CT included major changes to the Immunization content especially around the concepts that are generic.
Between July 30 and September 3, 2020, Infoway hosted 5 presentations on different topics of importance: the Kick off meeting, the Influenza vaccines, the combined Diphtheria, Pertussis, Tetanus, HB, Hib and Polio vaccines, the Subset (refset) requirements and the naming conventions.
The Immunization redesign work was supported by different reference documents:
Pharmaceutical Dose Form Hierarchy - Editorial Guidelines for Modeling and Terming v1.0.pdf
SNOMED CT Drug Model for supporting National Extension V1.0.pdf
Medicinal Product Hierarchy (including Vaccine Products) - Editorial Guidelines
A working document was provided to the Public Health and the Health Terminologies Communities: Vaccines changes for review
A Summary of changes and questions pending answers - SNOMED CT® Immunization Redesign Project was also shared with the communities.
We welcome feedback, comments and concerns. They can be posted on the PHS or HTC Forums or sent to [email protected].
Canada Health Infoway (Infoway) publishes English Generic Editorial Guidelines. These guidelines should be consulted, along with the guidelines in the following pages prior to creating any new content for submission to Infoway.
Implementers should be familiar with the SNOMED International Guidelines prior to creating submissions for new content.
The development of the Immunization content is based on different documents such as:
Main Reference Documentation
Other references, available in French and English, were used as part of this work. It is expected that any future development will consider these:
A) Canadian Products
1- Product monograph
a) For the current vaccine tradename
b) For discontinued vaccine tradename
c) For the current passive immunizing agent tradename
d) For discontinued passive immunizing agent tradename
2- Vaccines and Passive Agents Abbreviations List
a) For the current vaccine
The vaccine abbreviation is created by the Vaccine Vigilance Working Group (VVWG).
b) For the current passive immunizing agent
c) Discontinued vaccine
d) Discontinued passive immunizing agent
3- Marketing Authorization Holder (MAH) vs Manufacturer's abbreviation list
NOTE: Most of the Vaccine tradename and passive immunizing agent tradename product concepts have been developed using the Manufacturer's name and abbreviation. In the April 2019 release, some concepts have been updated to display the MAH instead of the Manufacturer. For details, refer to the Informs tickets BSCT-8425.
In some reference documentation, the Marketing Authorization Holder (MAH) is referred to as the manufacturer. This may not be true in all cases.
a) For the current vaccine tradename
b) For the current passive immunizing agent tradename
B) Non-Canadian Products
This logo is used throughout the guide to identify areas that will require future clarification from the community of practice.
