Union health ministry will launch the second phase of nationwide immunisation drive, Indradhanush 2.0 in the second week of December.
The program aims to vaccinate children in 271 districts with an immunisation coverage of less than 70%.
Only 16 districts currently have routine immunisation coverage of 90% or more.
It plans to achieve at least 90% pan-India immunisation coverage by 2022.
In 2017, the government launched Intensified Mission Indradhanush (IMI) to reach out to children who were not immunised at all or may had received partial immunisation.
Within a year, around 5 million more children were immunised against 12 vaccine preventable diseases.
This year (2019) India is commemorating 25 years of its successful Pulse Polio Programme.
