lotNumber and expirationDate max cardinality and feedback to HL7 International

[m-shoop]

The administeredProduct extension (BeAdministeredProduct ) per issues 49 and 66 appears to have been created to represent the vaccine as a Medication reference which the base spec does not support. This reduces interoperability since elements that have a max cardinality of greater than 0 in the base spec now have a max cardinality of 0 in the Belgian profile.

Has Belgium HL7 submitted feedback to HL7 International about representing the vaccine as a Medication reference? It's likely that Belgium's considerations apply to other locales, as well, and that the base resource should be expanded to support the Medication reference.

We are working with R4 in Belgium. We do understand that this might cause interoperability issues cross-border. About the cardinality of lotnumber and expiration date: it was put to 0 as the info should be put in the administered product
@costateixeira : any comments, any discussion you can have with HL7 int'l ?

HL7 Belgium brought it to HL7 int'l, and as such it was considered in R5

[costateixeira]

Yes, we have submitted feedback to HL7 international and the feedback was indeed accepted and the resource expanded: the extensions we need in Belgium have been moved to the core resource in R5. https://hl7.org/fhir/R5/immunization-definitions.html#Immunization.administeredProduct Can this issue be closed? or is there any other activity or clarification required?

@m-shoop We will close the issue for now, feel free to reopen it if needed.

Yes I agree this can be closed.
