What is the explanation for the fact that some of the areas where the Koprowski oral polio vaccine was given were close to the areas where the first AIDS outbreaks were seen?
The areas where Koprowski’s vaccine was used and where the first AIDS outbreaks occurred are also areas where chimpanzees that carry SIV live. So it makes sense that those areas were the same areas where SIV ‘jumped’ from chimpanzees to people, and HIV-1 and AIDS were first seen. Though some people believe that Dr. Koprowski did use chimpanzee organs to grow the virus for the vaccine, evidence indicates that chimpanzees were only used to test the vaccine, not to produce it.
