Turn scattered temperature logs into a live, tamper-evident record that catches breaches in real time.
01.
The Cold-Chain Monitoring module records sensor readings for every shipment, so a vaccine's exposure history is a complete, tamper-evident record rather than a spot check.
02.
When a reading leaves the safe range, the contract flags the shipment immediately, so a breach is acted on during transport rather than discovered after administration.
03.
The Traceability Ledger anchors each shipment from manufacturer to site, so a flagged batch can be located and every downstream custodian identified at once.
04.
The Quality and Recall Ledger quarantines an affected batch on-chain, so a compromised lot cannot be quietly issued at a vaccination site.
05.
A vaccination site confirms an intact cold chain before accepting a shipment, so only doses with a clean temperature history reach patients.
06.
An immunization program queries the temperature and custody record for any batch, replacing manual data-logger downloads with a live verifiable view.
Follow one vaccine shipment from dispatch through a transit breach to a quarantined batch that never reaches patients.

Cerulea decomposes vaccine cold-chain compliance into modular contracts. Each layer dispatches, monitors, quarantines, and verifies so no compromised dose reaches a patient.
Verified cold-chain integrity is a horizontal capability. Here is how different actors in vaccine distribution put it to work.
Ship with a monitored, tamper-evident temperature record from the dock, protecting product efficacy and enabling batch-precise action when a breach occurs in transit.
Key Asset Types
Prove an unbroken cold chain across each leg and catch excursions in real time, so a temperature failure is contained during transport rather than after delivery.
Key Asset Types
Confirm every administered dose came through an intact cold chain and quarantine compromised batches network-wide, replacing manual logger reviews with a live record.
Key Asset Types
Whether you are bridging distribution management systems or capturing readings from cold-chain data loggers, Cerulea routes both into one temperature record.
For programs on legacy distribution and inventory systems. Shipment and acceptance events are translated into signed on-chain records through the API gateway.

Building a vaccine cold-chain ledger with real-time breach detection, batch quarantine, and site verification from scratch requires specialised engineers and long distribution integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects immunization supply-chain integration benchmarks. Wiring distribution systems to sensor feeds, building breach detection, and shipping batch quarantine and site verification for an average program takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your temperature and recall rules into pre-audited WebAssembly binaries and provisions the cold-chain ledger instantly.
