How a state health department deployed an immunisation tracking and reporting platform at the scale of 2 million patient records — the technical architecture that made it possible, and the public health impact achieved.
Get StartedState and provincial immunisation registries underpin childhood immunisation, flu campaigns, pandemic response, and school-entry compliance. Building one across millions of records — hospitals, clinics, pharmacies, school health programs, and public health departments — is high-stakes health informatics.
Statewide immunisation tracking for childhood programs, flu campaigns, and school entry.
A state agency replacing a registry built more than 15 years earlier.
2 million patient records with real-time submission and query at the point of care.
Four pathways, including a web portal that completes a record in under two minutes.
Horizontally scalable cloud that absorbed 4x peak volume during a vaccination campaign.

The legacy registry left data stale and incomplete.
The shift from delayed batch submission to real-time FHIR transformed the registry into a clinical decision-support tool — current at the point of care rather than weeks out of date.
Within six months, 94% of immunisations from participating providers appeared in the registry within minutes of administration rather than days or weeks.
Pediatric and family medicine practices query the registry at well-child visits to verify status instead of relying on parent-reported history — catching gaps missed in previous visits.
Childhood immunisation coverage improved measurably in the year after go-live, attributable in part to the better registry data's ability to identify and close gaps.
During a regional campaign eight months post-launch, peak daily volume hit ~4x normal as community events submitted en masse — handled without service degradation.
Every number below was measured in production after launch — not projected in a pitch deck.
Patient Records Migrated — Up to 15 years of history preserved
Real-Time Submission Rate — Within minutes — was days/weeks
Peak Volume Handled — During a vaccination campaign
Per-Record Direct Entry — Lowest-barrier submission path
