CoWIN (Covid Vaccine Intelligence Network) is an Indian government web portal for COVID-19 vaccination registration, owned and operated by India's Ministry of Health and Family Welfare. It displays booking slots of COVID-19 vaccine available in the nearby areas and can be booked on the website. The site also provides vaccination certificates to the beneficiaries, which act as Vaccine Passports during the COVID-19 pandemic for the beneficiaries and can be stored in Digilocker. Users can access the platform via desktop, tablet, and mobile phones.

CoWIN serves the function of registration, appointment scheduling, identity verification, vaccination and certification of each vaccinated member.Registration for the vaccination slots can be booked on the same day or a few days prior. The platform has also been integrated in the Aarogya Setu and UMANG Apps. The certificate after COVID-19 vaccination can also be obtained through the platform. To expedite the development of this platform, several existing digital assets were leveraged, such as : Electronic Vaccine Intelligence Network (eVIN),Digital Infrastructure for Vaccination Open Credentialing (DIVOC), DigiLocker, Surveillance and Action for Events Following Vaccination (SAFE-VAC). CoWIN application was developed with five modules: the orchestration module; the vaccination cold chain module; the citizen registration module; the vaccinator module; and the certificate, feedback, and adverse event following immunization reporting module.[5] As of now, eight vaccines can be registered on the platform in the country Covishield (18+), Covaxin (15+), Corbevax (12-14), Sputnik V (18+),Corbevax (12-14), Gemcovac (18+) Incovacc (18+), ZyCoV-D (18+) and Covovax (12+).

In the future, the Health ministry is working on upgrading CoWIN for the effective implementation of India’s universal immunization programme. Co-WIN platform will be used for booking slots for the routine vaccinations like Polio and Hepatitis. This will allow healthcare professionals to digitally track the immunization status of beneficiaries (mother and children) on a real-time basis and address the vaccination needs immediately.

Doctors and medical professionals may soon be able to manage appointments and maintain patient records over the vaccine platform CoWIN, with the National Health Authority (NHA) integrating it with the Ayushman Bharat Digital Health Mission (ABDM)—the backbone of India’s digital healthcare system. This lightweight health management information system (HMIS) solution will allow small clinics and providers to manage appointments, patient information and prescriptions. The HMIS will be integrated with all ABDM modules and allow the doctor and clinic to create a health professional ID and a health facility ID.


Prime Minister, Narendra Modi had envisioned roll-out of a technology based citizen facing platform for smooth running of Covid-19 vaccination in India, long back in May 2020. The government repurposed its eVIN platform and tested it in more than 700 districts before the launch of CoWIN. However, the PM sensed that the technological backbone would need more robustness and decided to revive the team that had delivered Aadhaar and brought Dr RS Sharma[9] on board who previously headed the Telecom Regulatory Authority of India and the Unique Identification Authority of India. Within days, Sharma was appointed Chair of the Empowered Group of technology and Data management and member of National Expert Group on Vaccine Administration(NEGVAC), a body constituted by the Government of India and also the CEO of the National Health Authority (NHA).

On 16 January 2021, CoWIN was launched and started offering COVID-19 vaccination for Frontline Workers in the country. On 1 March 2021, the platform started offering vaccination to all residents over the age of 60, residents between the ages of 45 and 60 with one or more qualifying comorbidities, and any health care or frontline worker that did not receive a dose during phase 1.

On 28 June 2021, it was announced that an open source version will be given to over 50 interested countries.[15] CoWIN has been the fastest growing tech platform in the world. India has also signed an MoU with the government of the Co-operative Republic of Guyana for sharing CoWIN.

On September 17 2021, CoWIN handled the volume of 25 million doses in 24 hours without any glitches.
