Himachal is a hilly state. The major challenge is that many areas are difficult to reach and access to those areas is a major problem for us. eVIN has come as a boon. With the introduction of eVIN, we are able to plan our immunization sessions effectively and smoothly because now we know about vaccine indents and requirements well in time. Wastage of vaccines has also reduced and that is an important aspect of eVIN. We can plan immunization sessions effectively eVIN has helped create a strong chain between the vaccine handlers, the vaccinators and the programme managers. Vaccine cold chain handlers have become important now.
