Keira Knightley Helps UNICEF in Fight Against Polio

Actress recently traveled to Africa as part of the organization's efforts to vaccinate children around the world

No wonder James Righton wants to marry Keira Knightley!

The Oscar-nominated actress, who is engaged to the Klaxons keyboardist, recently traveled to Chad in Africa on behalf of UNICEF's Soccer Aid 2012.

Knightley's mission focused on the organization's efforts to raise money in order to provide polio vaccinations to millions of children around the globe.

"It doesn't need to be like this," the actress says in a video chronicling her visit to the region. "Every minute of every day, three children die needlessly from a disease that could have been prevented by a simple, lifesaving vaccine."

Yep. Righton is one lucky fella.
