Overview of the theory

One theory of the origin of AIDS is that it developed from contaminated vaccines used in the world's first mass immunisation for polio. There are a number of reasons why this theory is plausible enough to be worthy of further investigation.

If this theory is correct, it has serious ethical, health and policy implications. In particular, it points to the danger of interspecies transfer of material through vaccinations, organ transplants, etc., which could lead to new variants of AIDS as well as other new diseases. As well, studying the theory may lead to insights about responding to AIDS and preventing new diseases.

However, there has been no sustained attempt to test the theory. This could be done, for example, by testing stocks of polio vaccine for the presence of SIV. An offer to undertake tests was made as early as 1991; only in 2000 were some samples tested, and then only US-made vaccine. Another possibility would be to test stored blood samples in Africa from before 1950. If HIV is found, this would undermine the theory.

Although the theory has not been properly examined, many people seem to believe it has been refuted. Hilary Koprowski published a letter in Science in 1992 attacking the theory. In 1993, Rolling Stone, which had published a widely publicised article by Tom Curtis about the theory, published an "update", interpreted by Science as a retraction. The public record thus suggests that these contributions have been the final word.

Actually, this appearance of "refutation" was due to the exercise of power, not scientific judgement. Science refused to publish a reply to Koprowski's letter by Curtis and, later, another reply by eminent biologist W. D. Hamilton. Nature has received substantial submissions about the theory from at least six scholars but has not published any of them. Rolling Stone's "update" was the aftermath of a legal action for defamation by Koprowski against Rolling Stone and Curtis. Thus, it has been editorial prerogative and legal action that have given the impression that critics of the theory have been unanswered.

To help rectify this situation, provided here are a number of key documents presenting the theory and commenting on it. Also given is a list of publications about the theory. This material is provided by Brian Martin who as a social scientist has been following the theory since 1991. It is part of a page on suppression of dissent. Comments and additional contributions are welcome.


Some key publications about the theory
(in reverse chronological order) 


Edward Hooper, The River: A Journey Back to the Source of HIV and AIDS (Harmondsworth: Penguin; Boston: Little, Brown, 1999; revised edition, Penguin, 2000). This is an enormous but highly readable scientific blockbuster, providing the most detailed examination of the polio vaccine theory yet available, including many new findings. It has generated widespread discussion and debate and has established the polio-vaccine theory of the origin of AIDS as by far the strongest contender to the cut-hunter orthodoxy.

The River is available from Penguin Books in the UK, www.amazon.com in the US and Standish Prideaux & Pye in Australia.

Omar Bagasra, HIV and Molecular Immunity: Prospects for the AIDS Vaccine (Natick, MA: Biotechniques Books, 1999). This technical scientific book presents a new theory of molecular immunity for the origin and history of HIV-1, which, it is argued, most likely derived from polio vaccinations in Africa.
Kiley R. Prilliman
reviews the book in the prestigious journal Cell. Julian Cribb has provided insightful comments on the book for nonspecialists. The author, Omar Bagasra, can be contacted at omarb@sc.rr.com. The book is available from Eaton Publishing, 154 East Central Street, Natick MA 01760, USA, phone 508-653 6272, fax 508-653 2706.

Julian Cribb, The White Death (Sydney: Angus & Robertson, 1996). An engaging book focussing on both the polio-vaccine-AIDS theory and its reception by the scientific community. The author can be contacted at <julian.cribb@nap.csiro.au>.
