India’s immunization system has received a major digital boost through two flagship platforms U-WIN and eVIN backed by the United Nations Development Programme (UNDP), significantly enhancing tracking, efficiency, and coverage under the Universal Immunization Programme (UIP). According to the UNDP India Annual Report 2025, these government-led initiatives have created a seamless ecosystem that connects real-time vaccination records for beneficiaries with end-to-end visibility of vaccine stocks and cold-chain conditions.

U-WIN, a national immunization registry launched as a pilot in early 2024 and scaled nationwide, serves as a people-centric digital tool for registering and monitoring pregnant women and children. It records every vaccination event, reduces dropouts through timely reminders and continuity of care, and enables “anywhere access, anytime vaccination.” The platform builds on lessons from CoWIN during the COVID-19 response but focuses on routine immunization against 12 vaccine-preventable diseases. To date, U-WIN has tracked services for around 32 million pregnant women and 97 million children, empowering health workers to identify left-outs and dropouts instantly and plan sessions more effectively.

Complementing this is eVIN (Electronic Vaccine Intelligence Network), a smartphone and cloud-based system that digitizes vaccine stock management and cold-chain monitoring. Rolled out across all districts with UNDP technical support since its inception, eVIN provides real-time data on vaccine availability, consumption, and temperature at over 30,000 cold-chain points. It has facilitated the safe handling and distribution of more than 650 million vaccine doses, dramatically cutting wastage, eliminating stock-outs, and ensuring vaccines reach beneficiaries in potent condition even in remote areas.

Together, U-WIN and eVIN form a powerful integrated backbone for India’s immunization efforts, aligning with the Ayushman Bharat Digital Mission and advancing Sustainable Development Goals. The platforms have improved last-mile delivery, strengthened data-driven decision-making, and boosted overall health system resilience. India’s success has attracted global interest, with elements of these systems shared via South-South cooperation to countries like Zambia and Lao PDR to enhance their own immunization tracking and supply chains.

The UNDP report underscores strong government leadership in scaling public digital systems that reach vulnerable populations, including women, children, and low-income households. These achievements reflect a decade of collaboration between India’s Ministry of Health and Family Welfare and UNDP, evolving from early vaccine logistics digitization to comprehensive immunization registries.
