Reducing the infectious diseases burden through "life course approach vaccination" in India-a perspective.

The burden of vaccine-preventable diseases is increasing day by day across all age groups. However as per the universal immunization programme, we vaccinate only under-fives and antenatal mothers, a large portion of the vulnerable population remain unvaccinated and the concept of “life course approach” regarding vaccination is missing. It increases the overall burden to the already constrained Indian health care system. As India, now has become the largest manufacturer of multiple vaccines, we have continuous chain healthcare points (primary-tertiary level), with dedicated manpower in the public health sector that is why in this paper we are proposing to expand the horizon of the vaccination process using a “life course approach”. It will not only directly benefit the vulnerable populations (individual level), but also it can benefit the nation, indirectly. Although we may face challenges at multiple phases (conception to implementation), they can be overcome by multisectoral and multipronged innovations.
