Oral polio vaccine: fact versus fiction.

The author of this article has now become the principal target of the accusation that HIV-1 was introduced into man through the wildcat production of an oral polio vaccine in chimpanzee cell culture more than 40 years ago in the Belgian Congo. The putative evidence presented in support of this accusation rests essentially on testimonials by local witnesses. Such an accusation is strongly rejected on basis of a factual review of the author's career and his publications, as well as his total incapability to have managed such a feat at the supposed time.
