Sitting in her small house in Kotana village in Baghpat district of western Uttar Pradesh, 25-year-old Ruby tells the local anganwadi worker yet again that she won’t vaccinate her 16-day-old son as her husband has refused permission. This is the third visit by Beena Devi, the anganwadi worker of the area, to Ruby’s home in the Muslim basti of the village. Under the government’s Universal Immunisation Programme (UIP), she is required to make calls at and inquire about all newborn children and keep track of the immunisation schedule of each child. It is a task that has proven to be almost unachievable in most parts of state.
