Gates Pledges Big Money for AIDS Vaccine

In a generous move by the Bill and Melinda Gates foundation, Gates promised $100 million in an effort to fight for a vaccine to stop the widespread and massively increasing number of cases of the HIV virus, which causes AIDS. Speaking at the World Economic Forum, Gates also issued a challenge to other economically well off individuals to do the same, in hopes that a vaccine could be discovered soon. Yahoo! also joined the Gates Foundation, pledging $5 million to be used to raise public awareness via Yahoo! sites around the globe.
