Mission Indradhanush improved child vaccination rates in India By IANS | 1 Views Mission Indradhanush improved child vaccination rates in India. Image Source: IANS News New Delhi, July 18 : An estimated 25.5 million children across India were vaccinated under India's Mission Indradhanush (MI) child vaccination campaign during March 2015-July 2017, according to a study. In December 2014, the Government of India launched MI, with the objective of increasing full immunisation coverage. MI was a periodic intensification of the routine immunisation (PIRI) programme, which targeted unvaccinated and under-vaccinated children by allocating more resources to underserved areas. The programme was implemented in 528 districts -- with low initial full immunisation coverage and high dropout rates -- in four phases during March 2015-July 2017.
