Having an uncomplicated picture of which supplies are where, and when more are needed, is a basic requirement for any logistics system, especially for reliably delivering vaccines to remote healthcare clinics. The absence of this information will inevitably result in running out, having too much, or wasting, supplies.
eVIN (electronic vaccine intelligence network) aims to strengthen the evidence base for improved policy-making in vaccine delivery, procurement and planning for new antigens in India. eVIN provides an integrated solution to address widespread inequities in vaccine coverage by supporting state governments in overcoming constraints of infrastructure, monitoring and management information systems and human resources, often resulting in overstocking and stock-outs of vaccines in storage centres.
eVIN (Electronic Vaccine Intelligence Network) is an indigenously developed technology system in India that digitizes vaccine stocks and monitors the temperature of the cold chain through a smartphone application. The innovative eVIN is presently being implemented called across twelve states in India. eVIN aims to support the Government of India’s Universal Immunization Programme by providing real-time information on vaccine stocks and flows, and storage temperatures across all cold chain points in these states.
The integrated solution combines:
All cold chain handlers are provided smart phones with the eVIN application which allows for the digitization of vaccine inventories. As a routine task, every cold chain handler enters the net utilization for each vaccine in the standardized registers at the end of every immunization day. This is simultaneously updated in the eVIN application and uploaded on a cloud server which can then be viewed by programme managers at district, state and national level through online dashboards. In addition to providing real-time information on vaccine stocks, the system also helps to track storage temperature of vaccines. SIM-enabled temperature loggers attached to the cold chain equipment capture temperature information through a digital sensor placed in the refrigerator. Temperature data is recorded every ten minutes and updated at an interval of sixty minutes on the server via General Packet Radio Service (GPRS). In case of temperature breach, the logger alarms and sends email and SMS alerts to responsible cold chain technicians and managers.
eVIN empowers the cold chain handlers by building technical capacities and providing a robust decision-making tool for cold chain managers through a complete overview of vaccine replenishment times, supply and consumption patterns.
By streamlining the vaccine flow network, eVIN is a powerful contribution to strengthening health systems and ensures equity through easy and timely availability of vaccines to all children.
Under the National Health Mission (NHM) of Ministry of Health and Family Welfare, as of August 2020, eVIN has reached 32 States and Union Territories (UTs) and will soon be rolled-out in the remaining States and UTs of Andaman & Nicobar Islands, Chandigarh, Ladakh and Sikkim. At present, 23,507 cold chain points across 585 districts of 22 States and 2 UTs routinely use the eVIN technology for efficient vaccine logistics management. Over 41,420 vaccine cold chain handlers have been introduced to digital record-keeping by training them on eVIN. Nearly 23,900 electronic temperature loggers have been installed on vaccine cold chain equipment for accurate temperature review of vaccines in storage.
The Electronic Vaccine Intelligence Network has helped create a big data architecture that generates actionable analytics encouraging data-driven decision-making and consumption based planning that helps in maintaining optimum stocks of vaccines leading to cost savings. Vaccine availability at all times has increased to 99% in most health centers. An activity rate of more than 99% reflects high adoption of the technology across all health centers where eVIN is currently operational. While instances of stock-outs have reduced by 80%, the time taken to replenish stocks has also decreased by more than half, on an average. This has ensured that every child who reaches the immunization session site is immunized, and not turned back due to unavailability of vaccines.
