Issuing COVID-19 Vaccination Certificates in India
The Government of India launched the COVID-19 vaccination program in January 2021. The roll-out of the Co-WIN application was key to this. While the cloud-based platform covered all the major modules that a vaccination program of this scale should have, it lacked the digital credentialing feature that was critical to open up travel and economy amid the COVID-19 pandemic. DIVOC was integrated with Co-WIN in January 2021, making India the first country where the digital verifiable credentialing was implemented. Over 1.9 billion vaccination certificates have been issued in India so far.
Since India was the first country to implement DIVOC, a component-wise release was done as there was no generic version available back then. Hence, the release versions are component-specific:
Certificate generation: A certificate is generated in real-time every time a person’s vaccination record is created in Co-WIN. Citizens get the latest dose certificate, which could be provisional, final, or the precaution dose. Two types of certificates are issued: domestic (age is mandatory) and international travel certificates (date of birth is mandatory). Further, DIVOC certificates (domestic) can be generated in 22 languages in India.
Note: These are April 19, 2022, numbers
Reconciliation service: This service was introduced in India to resolve any initial (bulk) data entry discrepancy such as date of vaccination.
