Srinagar, June 29: As dawn breaks over Kashmir’s mountains, teams of health workers shoulder vaccine carriers and set out on arduous journeys across rushing mountain streams, dense forests and steep ridges to ensure that not a single child is left behind in the Pulse Polio campaign. For these frontline workers, vaccination is not just a routine assignment - it is a mission that often takes them to some of the valley’s most inaccessible villages, including settlements tucked away along the Line of Control (LoC) in Uri, Boniyar and Kupwara districts. Armed with vaccine carriers packed with ice packs, registers and essential supplies, the teams trek for hours through rugged mountain trails, cross icy nallahs on foot, and navigate difficult terrain to reach nomadic families, shepherd settlements and isolated hamlets where roads simply do not exist.
