This value set includes codes based on the following rules:
http://smart.who.int/immunizations/CodeSystem/IMMZ.D2.DT.Inputs| Code | Display | Definition |
| csailt9m-34.43 | Client's age is less than 9 months | Today's date − "Date of birth" < 9 months |
| nmpsdwa-53.130 | No meningococcal primary series dose was administered | Count of vaccines administered (where "Vaccine type" = "Meningococcal vaccines" and "Type of dose" = "Primary series") = 0 |
| csaimt9m-34.43 | Client's age is more than 9 months | Today's date − "Date of birth" ≥ 9 months |
| ompsdwa-54.130 | One meningococcal primary series dose was administered | Count of vaccines administered (where "Vaccine type" = "Meningococcal vaccines" and "Type of dose" = "Primary series") = 1 |

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 |
