All these aspects were discussed... Several schemes were also launched. But not much success was gained in the past."He also said that countries with fewer facilities were ahead of India in these fields."To end this situation, we since 2014 have been working with new strategies in the field of vaccination, cleanliness and child nourishment and decided to conduct these on a mission mode."Speaking about Mission Indradhanush, he said over 3 crore 40 lakh children and 90 lakh mothers had been vaccinated since the launch of the scheme.The concept of serving of food in schools -- midday meal -- was an old concept, he said."We are ensuring that children will get enough clean and nutritious food," he said.
