Each year, more children are born in India than anywhere else—27 million all told. Their chance to survive and thrive depends heavily on vaccination against illness, death or lifelong disability.

It’s a mammoth task. Immunizing all newborns plus 126 million children under five and 30 million pregnant women who also need protection requires 650 million doses of vaccines annually. These must flow through 27,000 distribution points before they are used in 9 million vaccination sessions.

They travel through a supply chain involving planes, trains, buses, motorbikes and people on foot. Read how eVIN is helping transform lives through its efficient and innovative system.
