The Gates foundation just donated $750 Million to pay for children's vaccination. The endowment for the foundation is estimated to be over $27 Billion Dollars. So far, I know that Gates has given:

- $60M for HIV Research
- $40M for Education
- $750M for Children's Vaccinations

From what I hear from reputable sources, the foundation is a competitive place to get a job - no doubt the IQ factor and the culture is supposedly similar to Microsoft.  My sister recently received her Ph.D. in Bacteriology and wants to work there- turns out the Foundation is very highly regarded in Academic Circles.
