Overview

Surokkha is Bangladesh’s national COVID-19 vaccination management platform, built to handle one of the largest vaccination campaigns in the world.
The system enabled citizens to register, schedule vaccination appointments, track doses, and download digital certificates, while providing government authorities with tools to manage vaccination centers, inventory, and nationwide reporting.
Designed for massive scale and reliability, Surokkha supported millions of simultaneous users and coordinated thousands of vaccination centers across the country.
Through a unified digital ecosystem, the platform successfully managed 150M+ citizens and more than 108M vaccinations.

The Challenge

Launching a nationwide vaccination program during a global pandemic required solving multiple operational and technical challenges:

Operational Challenges

  • Lack of digital system for mass vaccination
  • Coordinate thousands of vaccination centers nationwide
  • Track multiple dose phases (eventually scaling to 4 doses)
  • Support citizens with varying levels of digital literacy

Technical Requirements

  • Handle millions of concurrent registrations
  • Real-time vaccine center coordination
  • Secure digital certification system
  • Multi-platform accessibility

Timeline Pressure:

  • Month 1 deadline to launch public registration
  • Iterative delivery of vaccination phases
  • Zero tolerance for system failures during critical health crisis
  • Integration with national ID systems

National Requirements

  • Handle real-time registration for millions of citizens
  • Ensure seamless scheduling and vaccination tracking
  • Support instant certificate generation and verification
  • Maintain high data accuracy and system reliability
