Singaporean healthcare services provider Zuellig Pharma is using a blockchain-based network to track COVID-19 vaccinations to prevent practitioners from administering expired vaccines.

eZTracker uses the SAP blockchain to capture, track and trace multiple data points to improve supply chain transparency. The eZTracker website explains how it works:

Zuellig Pharma says that its new “eZTracker” management system can help prevent the use of improperly stored or counterfeit vaccines by allowing its clients to instantly verify the provenance and authenticity of their vaccines via a mobile app.

 

“Accidents involving expired or improperly stored vaccines can be avoided,” said Daniel Laverick, vice-president and head of digital and data solutions at Zuellig Pharma.

The SAP Blockchain executes operations as a Blockchain-as-a-Service (BaaS), allowing its clients to develop customized blockchain extensions for their existing applications. According to SAP, 77% of the world’s transaction.

Laverick explained at the time.

 

“Users such as healthcare professionals and patients are able to verify the authenticity of the vaccine by scanning a unique data matrix code on the product pack."

Back in 2020, Zuellig partnered with pharmaceutical company MSD to deploy eQTracker in Hong Kong, where it was used to trace vaccines for Human Papilloma Virus, Gardasil.

 

"As the vaccines move through various handover points in the supply chain, the products' data points are loaded into eZTracker's secure blockchain ledger, and this ensures it can't be tampered with,”
