Starting September 27, 2023 The MCIR Data Quality team would like to inform you of an upcoming change to MCIR’s HL7 VXU interface.

Context: In the state of Michigan, immunization facilities are required to include a ‘Next of Kin’ section when reporting vaccinations administered to individuals under the age of 18.

Change: Starting on September 27, 2023 a warning will be indicated in the ACK message for any HL7 messages regarding individuals under the age of 18 that do not contain an NK1 (Next of Kin) segment including a person with a relationship type that MCIR accepts as a responsible person.
