Davos, Switzerland (CNN) -- Bill and Melinda Gates announced plans Friday to invest $10 billion in the fight against a number of illnesses including AIDS and said the record donation could save nearly nine million lives.
Speaking at the World Economic Forum in Davos, Switzerland, they said the 10-year program will focus on vaccines for AIDS, tuberculosis, rota virus and pneumonia.
"We must make this the decade of vaccines," said Bill Gates.
"Vaccines are a miracle," added Melinda Gates. "With just a few doses, they can prevent deadly diseases for a lifetime. We've made vaccines our priority at the Gates Foundation because we've seen firsthand their incredible impact on children's lives."
