The volunteers are part of ‘Har Ghar Dastak’, the health department’s drive to achieve 100 per cent vaccination of the second dose by November 30. The time limit was set by Chief Minister Jai Ram Thakur himself. The initiative relies on a network of mobile teams made of healthcare professionals and volunteers knocking on the doors of residents in even the most remote and inaccessible valleys and hamlets. In the past 15 days, the valleys have traversed hostile terrains and weather conditions in several largely inaccessible regions such as Kullu, Lahaul-Spiti, Chamba and Sirmaur.
