| Title | CH EKM Extension: Immunization unknown |
| Realm | ch |
| Authority | hl7 |
| Description | This CH EKM modifier extension records that it is NOT KNOWN whether the vaccination described by this Immunization took place ('unbekannt' on the reporting form), as opposed to it being known not to have taken place. It is a modifier extension because the resource carries status = not-done, which without this extension would assert that the vaccination did not happen. |
