# Illustrative program eligibility API
GET /v1/public-health/eligibility?program=breast-cancer&patientId=123&jurisdiction=FR

The eligibility route is illustrative; official national program rules and reporting integrations remain jurisdiction-specific.

Error Handling

Program rules unavailable → do not guess eligibility

Conflicting history → reconcile before outreach/clinical action

Failed authority submission → retry/exception queue

Duplicate immunization/screening event → deduplicate using source identifiers

Patient opt-out/consent restriction → enforce program/legal rules

Best Practices

Version national program rules

Keep invitation status separate from clinical completion

Preserve source vaccination/screening evidence

Use standard vaccine/result codes via MSIS

Prevent duplicate outreach and duplicate registry submission

Audit program eligibility and reporting decisions
