Cold Chain Mission with Ewan McGregor
Hollywood actor Ewan McGregor travels to the ends of the Earth on his mission to immunise some of the hardest-to-reach children in the world. The routes vaccines travel are known as cold chains, and a vast network of them exist across the globe. The fragile nature of the vaccines means they must be kept constantly cold as they are passed along the supply chain, from freezer to freezer - wherever that may be.
Ewan follows three of the world's toughest cold chains, supported by Unicef, who immunise over half of the world’s children. His journey takes in the bustle of India, the isolation of Nepal and the wilds of Central Africa, as he discovers just how much it takes to save children's lives.
