About Grand Challenges Explorations

The Bill & Melinda Gates Foundation announced that it was committing $100 million over five years to create a new fast-track grants initiative to support innovative, early-stage global health research. The new program, called Grand Challenges Explorations, was an expansion of the Gates Foundation's commitment to the Grand Challenges in Global Health. The program's goal is to engage more of the world's innovators and to do so more quickly. Initial grants are for $100,000; successful projects can be awarded follow-on grants of up to $1 million.
