Polio Vaccine, Simian Monkey Virus and cancer links
Some 9 years ago CANCERactive covered several research studies from Japan on the higher incidence of Simian Monkey Virus (SV40) in people diagnosed with cancer.
The background to this is the Salk polio vaccine which, at the outset, used Simian Monkeys as the developing ground for the vaccine. Too late and after over 98 million vaccine doses had been prepared and over 30 million people had been inoculated, it was found that the Simian monkeys had a virus which was thus contained in the vaccine. The Salk vaccine then changed to use another animal source as its development host.
But. At the time we expressed great concern following the Japanese research revelations. One study looked at brain tumours where people who developed gliomas had much higher levels of SM40 than the population at large, and another study looked at cancers overall, with the same result. In 1961, the American National Institute of Health (NIH) stated that SV40 was ‘directly linked to causing tumor formation’.
It seems our fears were justified: The U.S. Centers for Disease Control and Prevention (CDC) recently posted a fact sheet entitled Cancer, Simian Virus 40 and Polio Vaccine outlining the links between the virus and cancer. However, this was removed hastily as controversy flared in America – but too late. RealFarmacy.com had already taken a copy of the damning report.
As you will see (original CDC page link http://www.cdc.gov and full archived page link: http://webcache.googleusercontent.com) the SV40 virus, has been linked to causing a variety of human cancers, including childhood leukemia, lung cancer, bone cancer, and Non-Hodgkin Lymphoma.
The CDC denies a definitive causal link between SV40 and cancer but implies it was problematic in relation to cancer development. Problematic is some sort of euphemism.
“Like other polyomaviruses, SV40 is a DNA virus that has been found to cause tumors and cancer,” explains RealFarmacy.com. “SV40 is believed to suppress the transcriptional properties of the tumor-suppressing genes in humans through the SV40 Large T-antigen and SV40 Small T-antigen. Mutated genes may contribute to uncontrolled cellular proliferation, leading to cancer.”
Michele Carbone, Assistant Professor of Pathology at Loyola University in Chicago, has found that the virus is present in many cases of both osteosarcoma bone cancer and the increasingly prevalent lung cancer variety known as mesothelioma. As it turns out, Carbone identified SV40 in about one-third of all osteosarcoma cases studied, and in 40 percent of other bone cancers. The same was true for 60 percent of all cases of mesothelioma. Obviously this conflicts with the accepted view that all mesothelioma is caused by asbestos exposure.
“Many authorities now admit much, possibly most, of the world’s cancers came from the Salk and Sabin polio vaccines, and hepatitis B vaccines, produced in monkeys and chimps,” adds RealFarmacy.com (http://www.realfarmacy.com).
