The journey of a vaccine
Ewan McGregor's cold chain mission
Back in 2011, our ambassador Ewan McGregor travelled with Unicef health workers to some of the remotest communities in India, Nepal and the Congo to find out how we get vaccines to the world’s hardest-to-reach children.
The journey starts in our supply warehouse. We call our supply chains ‘cold chains’ because vaccines need to be kept refrigerated at all times. But they don’t stay in the fridge for long.
We travel by air, boat and land to get vaccines to where they’re most needed. Here’s Ewan landing high in the Nepalese Himalayas, on his way to deliver vaccines to some of the country’s remotest communities.
And sometimes this can even mean trekking on foot. The cold box you can see here keeps vaccines between 2-8°C when we’re travelling through tropical areas, like jungles. Here, Ewan’s helping a vaccinator in the Congo.
Here’s a young girl in northern India receiving her polio vaccine. We vaccinate 1 in 3 of the world’s children – but we can only reach them with help from people like you.
