On April 7 World Health Day, India will launch an immunisation programme - Mission Indradhanush - that targets to vaccinate 90% of India's 2.7 crore children against seven life-threatening diseases by 2020.
India's Universal Immunisation Programme (UIP) – which vaccinates children against diphtheria, whooping cough, tetanus, polio, tuberculosis, measles and hepatitis B – currently fully covers only 65% of the country's children.
Nearly 25% of unvaccinated children are in 82 districts in four states — Uttar Pradesh, Bihar, Madhya Pradesh and Rajasthan.
