              Reason why the structured vaccination administration date or time is absent from the source data.

              This data element should be constrained to DV_CODED_TEXT in a template and bound to the HL7 FHIR Data Absent Reason value set, where possible. It describes why the structured administration date or time is missing and must not be used as the vaccination administration time.
