Discredited HIV/AIDS origins theories

Discredited theories

The Duesberg hypothesis, proposed by American biologist Peter Duesberg, claimed that AIDS results from noninfectious causes like drug use, and that HIV is a harmless passenger virus. This idea is widely considered unsupported by evidence, ignores contradictory findings, and has been thoroughly disproven. In 1987, some speculated that the AIDS epidemic might have been triggered by the mass smallpox vaccination campaign that eradicated the disease.

It is now understood that the smallpox vaccine can cause severe complications in people with weakened immune systems; one reported case involved a military recruit with dormant HIV who died shortly after vaccination, though no evidence was given for people without HIV. Some conspiracy theories suggest the smallpox vaccine was deliberately tainted with HIV. A 2010 study proposed that the end of smallpox vaccination, rather than the vaccine itself, might have contributed to HIV's emergence, as smallpox immunization could offer some protection against HIV infection or disease progression.

Regardless, unsterile injection practices during smallpox vaccination in Africa may have helped spread and mutate immunodeficiency viruses.

Prevalence of conspiracy beliefs

According to Phil Wilson, executive director of the Black AIDS Institute in Los Angeles, conspiracy theories are becoming a barrier to AIDS prevention because people believe that no matter what measures they take, they can still contract the disease. A 2005 study found that nearly half of 500 African Americans surveyed said HIV is man-made, more than one-quarter believed AIDS was produced in a government laboratory, and 12 percent believed it was created and spread by the CIA. At the same time, 75 percent said they believed medical and public health agencies are working to stop the spread of AIDS in black communities.

Prominent endorsers of discredited theories

The Nation of Islam endorses the view that governments and pharmaceutical companies have pursued genocidal racist policies including the creation and spread of HIV, and called for a boycott of U.S.-sponsored vaccination programs for children. Leonard Horowitz has been cited as influential in that boycott decision. Wangari Maathai, the 2004 Nobel Peace Prize laureate and environmental activist, was asked if she stood by a claim that AIDS is a biological weapon manufactured by the developed world to wipe out the black race.

She responded that she did not know who created AIDS but that such things do not come from the moon, and later issued a written statement denying that she believed the virus was developed by white people or white powers to destroy African people. In 2000, South Africa's Minister of Health Manto Tshabalala-Msimang received criticism for distributing a chapter from Cooper's book discussing this theory to senior South African government officials, and Nicoli Nattrass criticized her for lending legitimacy to Cooper's theories.
