This is why we LostTrust: Canada, U.S.
If you were born before 1963, your “safe: Polio vaccine, contained SV40 that was removed from the vaccine afterwards because it was safe, and there is no proof that it can cause cancer.
Yes. It did kill lab rats, monkeys and other animals. Yes, we now find it in Cancer tumors of people who were never vaccinated with the Polio-vaccine and we now know that SV40 can be transferred from human to human. But Public Health thinks that it is o.k., because SV40 is no longer in the vaccine.
“From 1955 to 1963, an estimated 10-30% of polio vaccines administered in the US were contaminated with simian virus 40 (SV40).”
“To date, there is no epidemiological evidence that shows people exposed to the SV40 contaminated polio vaccine are at increased risk of developing the type of cancers that rodents developed after direct exposure to SV40.”
But even if SV40-contaminated Polio vaccines cause cancer:
Health Canada: “polio vaccines used in Canada are not contaminated with SV40, because they are produced using materials completely free of SV40. Currently, the only polio vaccines used are those made with inactivated polio virus (IPV)”
CDC: Some studies looking at the relationship between SV40 and cancers found association between receipt of SV40-contaminated polio vaccine and development of cancer.
In the past, Polio-vaccines given to Canadians (and others around the world) contained SV40:
“Polio vaccines given to Canadians have been free of SV40 since the early 1960s.”
CDC: ” SV40 virus, when injected into newborn hamsters, caused large tumors under the skin as well as in the lungs, kidneys, and brain. At the time of this discovery, Salk’s vaccine had already been injected into tens of millions of people and thousands more were receiving it every day”
CDC: By the mid-1990s public health officials were confident that the inadvertent contamination of polio vaccines with SV40 didn’t cause cancer.”
What does the World Health Organization say?
The source(s) of contemporary SV40 infections is (are) unknown, but it is presumed that the virus is being transmitted among humans. SV40 can replicate in human cells.
SV40 DNA has been detected in human tumors in numerous independent studies, with the most commonly involved cancers being pediatric and adult brain tumors.
