"People are still dying because they happen to live in the wrong place, and that's unacceptable," contends Blaise Judja-Sato. "It's very important to find ways to reach mothers and children wherever they are." So Judja-Sato founded a non-profit called VillageReach to investigate what those ways are. The result? VillageReach's efforts, along with a creative mix of public and private partnerships, have translated to a 150% increase in vaccinations among one of the most remote villages in one of the poorest countries in the world.
