CoWIN is a government-owned web portal set up in 2021 to administer and manage India’s COVID-19 vaccine rollout
The platform, on a real-time basis, tracks vaccines and beneficiaries at the national, State, and district levels.
It monitors vaccine utilisation and wastage, and maintains an inventory of the vials.
For citizens, CoWIN verifies identity, helps schedule vaccine appointments, and issues a vaccine certificate.
The database captures information flowing from four separate input streams — citizen registration; health centres; vaccine inventory; and vaccine certificates.
Each stream functions independently, and at the same time exchanges data to minimise redundancies.
The platform is a microservices-based, cloud-native architecture developed from the ground up on Amazon Web Services (AWS).
A microservice architecture is a pattern that arranges an application as a collection of loosely linked, fine-grained services.
These services interact with each other through certain set protocols.
Electronic Vaccine Intelligence Network (eVIN)
eVIN aims to strengthen the vaccine supply chain management system and ensure real-time availability of stock information, temperature monitoring, and efficient vaccine logistics.
It enables the digital tracking and monitoring of COVID-19 vaccine stocks at all levels, from national to district to the individual vaccination center.
Digital Infrastructure for Verifiable Open Credentialing (DIVOC), a vaccine certificate issuer
Surveillance and Action for Events Following Vaccination (SAFE-VAC), a vaccine adverse event tracker.
