description: This profile sets minimum expectations for the Immunization resource to record, search, and fetch immunization history associated with a patient to promote interoperability and adoption through common implementation. It identifies which core elements, extensions, vocabularies, and value sets **SHALL** be present in the resource and constrains the way the elements are used when using this profile. It provides the floor for standards development for specific use cases. package_name: hl7.fhir.us.core derivation: constraint name: USCoreImmunizationProfile type: Immunization elements: status: short: (USCDI) completed | entered-in-error | not-done binding: {strength: required, valueSet: 'http://hl7.org/fhir/ValueSet/immunization-status'} mustSupport: true index: 0 statusReason: short: (USCDI) Reason not done binding: {strength: example, valueSet: 'http://hl7.org/fhir/ValueSet/immunization-status-reason'} mustSupport: true index: 1 vaccineCode: short: (USCDI) Vaccine Product Type (bind to CVX) binding: {strength: extensible, valueSet: 'http://cts.nlm.nih.gov/fhir/ValueSet/2.16.840.1.113762.1.4.1010.6'} mustSupport: true index: 2 patient: short: (USCDI) Who was immunized refers: ['http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient'] type: Reference mustSupport: true index: 3 occurrence: short: (USCDI) Vaccine administration date mustSupport: true choices: [occurrenceDateTime, occurrenceString] index: 5 occurrenceDateTime: {type: dateTime, short: (USCDI) Vaccine administration date, mustSupport: true, choiceOf: occurrence, index: 6} occurrenceString: {type: string, short: (USCDI) Vaccine administration date, mustSupport: true, choiceOf: occurrence, index: 7} primarySource: {short: (USCDI) Indicates context the data was recorded in, mustSupport: true, index: 8} package_version: 6.1.0-snapshot1 class: profile kind: resource url: http://hl7.org/fhir/us/core/StructureDefinition/us-core-immunization base: http://hl7.org/fhir/StructureDefinition/Immunization version: 6.1.0-snapshot1
