The Bill and Melinda Gates Foundation once again has put its money where its mouth is, with a $360 million investment in AIDS vaccine research.
The money, so far the largest single contribution to the field, supports the goals of the HIV/AIDS Global Vaccine Enterprise, an international alliance that the Gates Foundation helped organize. The new funds will go to research centers or consortia that are trying to improve tests to assess the immune responses triggered by vaccines or design vaccines that stimulate either antibodies or cell-mediated immunity. Letters of inquiry are due by 1 April. The size and number of awards will depend upon the quality and scope of the proposals.
