Polio Vaccine and Links to Cancer in Humans -
By Michael Dorausch, D.C.
Add Canada to the list of countries performing research suggesting a monkey virus that contaminated the polio vaccine in the 1950s and early 1960s is causing cancer among the millions who received the vaccine. According to news reports, similar findings have been replicated in New Zealand, China, Britain, France, Switzerland, and Belgium.
When reports first came in, researchers had thought that Simian Virus 40 (SV40) was linked only to rare brain, bone and lung cancers. But now, studies are showing a link to non-Hodgkin's lymphoma, which according to reports, "has inexplicably doubled over the past 30 years."
Researchers have also found SV40 in the tumors of families with Li-Fraumeni syndrome (LFS), a cancer predisposition syndrome associated with soft-tissue sarcoma, breast cancer, leukemia, osteosarcoma, melanoma, and cancer of the colon, pancreas, adrenal cortex and brain. According to researchers, individuals with LFS are at increased risk for developing multiple primary cancers.
A monkey virus in human vaccines?
Some of the Polio vaccine given in the fifties and early sixties was contaminated with the monkey virus SV40. In the US in 1961, the Food and Drug Administration ordered the vaccine's manufacturers to screen out SV40. According to reports, both the Salk and Sabin versions of the vaccine were made from dead monkey kidney cells.
