Immunization status


Parameter Case Report Form and Response Options

Immunization status
Influenza
Pneumococcal
BCG
COVID-19
Other

This profile of a FHIR Immunization is closely aligned to the Immunization-profile of the MIO Impfpass by Kassenärztliche Bundesvereinigung (KBV).

Use the Immunization.protocolApplied.targetDisease element to code the response options. This is vaccine preventatable disease being targetted.

Immunization.occurrence[x] shall cover the date when the immunization was last administered.

Immunization.vaccineCode can contain a code for the vaccine product administered. In case there is no information on vaccinations or no vaccnations are known, use the options from the absentOrUnknownImmunizations slice.

SNOMED provides codes for Covid-19 vaccinations which are included in the MIO Impfpass ValueSet to be used on Immunization.vaccineCode.coding:snomed. Branded products are out of scope of the International Edition of SNOMED. Therefore, the vaccine products must be mapped to the abstract codes as below:


Vaccine branded product SNOMED
Co­mir­na­ty® BioNTech/Pfizer 1119349007 |Vaccine product containing only Severe acute respiratory syndrome coronavirus 2 messenger ribonucleic acid (medicinal product)|
COVID-19 Vaccine Moderna® 1119349007 |Vaccine product containing only Severe acute respiratory syndrome coronavirus 2 messenger ribonucleic acid (medicinal product)|

ValueSets

The targetDisease value set is defined by KBV as part of the MIO Impfpass. The vaccine codes also originate from the MIO Impfpass: vaccineCode. Here a replica of the value set is used to add terminology server validation support for postcoordinated SNOMED expressions. The ATC vaccine codes below are identical to KBV MIO Impfpass but use an updated URL for the ATC code system.
