The Government of India plans to use eVIN- Electronic Vaccine Intelligence Network for the distribution of COVID-19 vaccine throughout the country.



As the date for arrival of Covid vaccine nears, the necessary infrastructure for distribution becomes utmost important.



  • Developed by UNDP with the support of Ministry of Health and Family Welfare, eVIN is a technology system that digitises vaccine stocks and monitors the temperature of the cold chain through a smartphone application.

  • It aims to support the government’s Universal Immunization Programme by providing access to real-time information on vaccine stocks and flows, and storage temperatures across all cold chain points in India. It has been implemented across 21 states and union territories.

  • The cold chain handlers at various points in the distribution network are provided smartphones with the eVIN application installed in them, for the digitisation of vaccine stock.

  • On a regular basis, each cold chain handler is required to enter the net utilisation for each vaccine in the standardised registers at the end of every vaccination day. 

  • It is simultaneously updated in the eVIN application and through it, uploaded on a cloud server which can then be viewed by programme managers at district, state, and national level through online dashboards, thereby providing real-time information on vaccine inventories.



  • eVIN helps to keep a track of the temperature at which the vaccine stock is stored. SIM-enabled temperature loggers are attached to the cold chain equipment which capture temperature information through a digital sensor placed in the refrigerator.

  • If there is any discrepancies in the optimum temperature level, the logger alarms and sends email and SMS alerts to responsible cold chain technicians and managers, so as to fix it quickly to curtail the damage if any.

  • By providing real-time updates on the vaccine location and quantity, eVIN helps the authorities to take informed decisions.

  • It keeps proper records of the vaccine stock, thereby maintaining optimum level of inventory and avoiding any under- or over-stocking.
