Preventing under-5 mortality is one of the key focus areas of policy makers nationally and internationally. The Sustainable Development Goals’ target 3.2 in alignment with WHO global strategy for mother and child 2016-2030 aims to achieve reduction of under-5 mortality to less than 25 per 1000 live births in every country. The Government of India 12th five year plan and also the reproductive, maternal, newborn, child and adolescent health (RMNCH+A) strategy 2013 focuses on bringing down under 5 mortality rate. About 25%, of under-5 mortality is due to vaccine-preventable diseases globally.
Vaccine preventable diseases put a huge financial and social burden on individuals, families and society. Children who contract these preventable diseases usually suffer from impaired physical growth, cognitive development, emotional development, and social skills. In India, vaccine-preventable mortality was estimated to be that of the 826,000 deaths in under-5 children, almost 604,000 deaths were due to vaccine-preventable diseases including diarrhea, pertussis, measles, meningitis, and pneumonia.
