Code Systemv0.1.0·draft
ICR Dose History / Zero-dose Status
A person's prior-dose status for the campaign antigen, at the time of a campaign contact — the polio SIA tally's core split (never received / previously received / no recall) and the zero-dose vs not-zero-dose axis. Carried per event by the prior-dose-status extension and aggregated as the dose-history coverage stratifier; feeds zero-dose reach and the proposed dropout/fully-immunized measures (forms-v1 / jul3-form-analysis §Aggregate #1).
Concepts (3)
3 shown| Code | Display | Definition |
|---|---|---|
| zero-dose | Zero-dose | Never received the antigen before this contact (the polio 'never received nOPV2 / >2 weeks old & never received OPV' cell). The zero-dose population. |
| previously-received | Previously received | Had received the antigen before this contact (the 'previously received' / 'not zero-dose' cell). |
| no-recall | No recall / no information | Prior-dose status unknown — caregiver cannot recall and no record is available. |
