SV40 Cancer Foundation
The SV40 Cancer Foundation was founded by Raphaele and Michael Horwin. The Horwin's son Alexander Horwin was born on June 7, 1996 and was given the oral polio vaccine in November 1997. On August 10, 1998, Alexander was diagnosed with medulloblastoma, a malignant brain cancer, leading to his death on January 31, 1999. The Horwins contend that the polio vaccine their son ingested was contaminated with SV40, leading to his death. Four independent PCR tests performed at four separate research institutes on Alexander's brain tissue demonstrated the presence of the virus. 
The SV40 Cancer Foundation views their mission as raising public awareness of this threat, and lobbying for more research funding for this area. On September 10, 2003, the Horwins were successful in getting Congressman Dan Burton, Chair of the Subcommittee on Human Rights and Wellness, U.S. Government Reform Committee to hold a hearing into SV40 contamination of vaccines.
The United States National Cancer Institute announced in 2004 that although SV40 does cause cancer in some animal models, "substantial epidemiological evidence has accumulated to indicate that SV40 likely does not cause cancer in humans.
