Mark Zuckerberg, Priscilla Chan to Spend $3B to Cure Disease

Facebook CEO Mark Zuckerberg and his pediatrician wife, Dr. Priscilla Chan, are launching an ambitious effort to spend $3 billion over the next decade to cure disease.

The goal is to "work together to cure, prevent or manage all disease within our children's lifetime," Chan said during an event in San Francisco for the Chan Zuckerberg Initiative, the couple's philanthropic group.

Chan spoke through tears as she recalled telling parents their child had an incurable disease or could not be revived.
