Keira Knightley: UNICEF Chad Trip for Soccer Aid 2012

Keira Knightley holds a young child named Idris during a recent trip to Chad, Africa, as part of UNICFEF‘s Soccer Aid 2012.

The boy was only a year old when he contracted polio, paralyzing him from the waist down.

Keira called on the public to help raise funds, which would go towards vital immunization and vaccinations for children around the world.

Check out footage from Keira‘s trip below, where she meets Idris‘s family and spends time with him as he learns to walk with leg braces.
