ValueSet IMMZD2DTMeaslesLowTransmission for IMMZ.D2.DT.Measles.Low transmission. Business rule: Determine if the client is due for a measles vaccination according to the national immunization schedule Trigger: IMMZ.D2 Determine required vaccination(s) if any Table: Countries with low levels of measles transmission (countries that provide first dose of measles-containing vaccine (MCV) at 12 months and second dose of MCV at 15 months)

Explanation of the columns that may appear on this page:
| Level | A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies |
| System | The source of the definition of the code (when the value set draws in codes defined elsewhere) |
| Code | The code (used as the code in the resource instance) |
| Display | The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application |
| Definition | An explanation of the meaning of the concept |
| Comments | Additional notes about how to use the code |
