In 1994, the Rockefeller Foundation, where Berkley was serving as Associate Director of Health Sciences, convened a series of international consensus meetings on the need for a new effort to address existing barriers to the development of an AIDS vaccine and jump-start AIDS vaccine research.
Under Berkley's leadership, the organization evolved into a worldwide public-private product development partnership with a staff of more than 200 employees that has worked with partners in 25 countries and, with partners, conducted 24 HIV vaccine trials [REF].
