funding sources to support the next phase of research into the Institute of Human Virology's (IHV) promising HIV/AIDS preventive vaccine candidate. The IHV vaccine program grants included $16.8 million from the Bill & Melinda Gates Foundation, $2.2 million from the U.S. Army's Military HIV Research Program (MHRP), and other research funding from a variety of sources including the U.S. National Institutes of Health (NIH). Priority and the 2008 Nobel Prize Assignment of priority for the discovery of HIV has been controversial and was a subplot in the 1993 American television film docudrama (and earlier book about the early history of AIDS) And the Band Played On. Montagnier's group in France isolated HIV almost one and a half years before Gallo, while Gallo's group demonstrated that the virus causes AIDS and generated much of the science that made the discovery possible, including a technique previously developed by Gallo's lab for growing T cells in the laboratory. When Montagnier's group first published their discovery, they said HIV's role in causing AIDS "remains to be determined." In 1989, the investigative journalist John Crewdson suggested that Gallo's lab might have misappropriated a sample of HIV isolated at the Pasteur Institute by Montagnier's group. Investigations by the National Institutes of Health (NIH) and the HHS ultimately cleared Gallo's group of any wrongdoing and demonstrated that they had numerous isolates of HIV of their own. As part of these investigations, the United States Office of Research Integrity at the National Institutes of Health commissioned Hoffmann–La Roche scientists to analyze archival samples established at the Pasteur Institute and the Laboratory of Tumor Cell Biology (LTCB) of the National Cancer Institute between 1983 and 1985. They concluded that the virus used in Gallo's lab had come from Montagnier's lab; it was a virus from a patient that had contaminated a virus sample from another patient. On request, Montagnier's group had sent a sample of this culture to Gallo, not knowing it contained two viruses. The sample then contaminated the pooled culture on which Gallo was working. On 12 December 1985 the Institut Pasteur filed suit to challenge a patent for an HIV test that had been granted on 28 May 1985 to the United States Department of Health and Human Services (HHS). In 1987, the two governments agreed to split equally the proceeds from the patent, naming Montagnier and Gallo co-discoverers. Montagnier and Gallo resumed collaborating with each
