In June 2011, thirty years after the start of the AIDS epidemic, heads of state and other
high-level government officials gathered in New York for the United Nations General Assembly
High-Level Meeting on AIDS. At that landmark meeting, UNAIDS Executive Director
Michel Sidibé called on leaders to end the epidemic by agreeing on a common agenda—an
agenda that would allow us to achieve the goal of “zero new HIV infections, zero discrimination
and zero AIDS-related deaths.”

2.1 G lobal Investments in HIV Vaccine R&D

Since 2001, global preventive HIV vaccine R&D investment has totaled US$8 billion, with an
average yearly investment of US$824 million. The 2011 total investment was US$845 million,
a decrease of US$14 million from 2010. As in past years, public-sector funders provided the largest
part of the investment, followed by the philanthropic sector and the commercial sector.18 In 2011,
the public sector provided US$702 million (83 percent), the philanthropic sector provided US$113
million (13 percent) and the commercial sector contributed US$30 million (4 percent). Investment
by European governments was US$48.5 million, a decrease of over US$12 million (21 percent)
from 2010, and a 40 percent decrease from the US$82 million peak in 2006. Philanthropic
investments in HIV vaccine R&D increased in 2011 by US$10 million (10 percent).
