A Traceable Vaccine Supply Management System

Area of Science:

• Health Informatics
• Blockchain Technology
• Vaccine Management Systems

Background:

• The COVID-19 pandemic highlighted critical flaws in existing vaccine management systems.
• Widespread vaccination efforts raised concerns regarding vaccine safety, traceability, and effectiveness.
• Current systems often lack transparency and robust security, leading to public distrust.

Purpose of the Study:

• To propose a novel blockchain-based traceable vaccine management system.
• To enhance the security, integrity, and transparency of vaccine supply chains.
• To address public and vaccinator concerns regarding vaccine management and effectiveness.

Main Methods:

• Implementation of a blockchain network utilizing smart contracts for immutable record-keeping.
• Integration of the Edwards-curve digital signature algorithm (EdDSA) for data security and integrity.
• Development of an access control mechanism based on participant authority for transparent data retrieval.

Main Results:

• The proposed system ensures end-to-end traceability of vaccines from production to administration.
• Smart contracts and EdDSA guarantee the security and integrity of vaccine-related data.
• Role-based access control enhances system transparency and operational integrity.

Conclusions:

• The blockchain-based system offers a secure, transparent, and traceable solution for vaccine management.
• This approach can significantly improve public trust in vaccination programs.
• The system is designed to be resilient against potential security threats and data manipulation.
