CDC Sends Fact Sheet Linking Polio Vaccine to Cancer Down the Memory Hole

The Center for Disease Control and Prevention website curiously mothballed pages admitting that the polio vaccine administered from 1955 to 1963 to over 98 million Americans was contaminated with a primate form of cancer virus.

cdclogoOther CDC web pages also referencing the link between the widely-distributed vaccine and cancer have similarly been discarded.

The pages are still available through Google’s cache system and at the links below:

http://www.cdc.gov/vaccinesafety/updates/archive/polio_and_cancer_factsheet.htm

http://www.cdc.gov/vaccinesafety/updates/archive/polio_and_cancer.htm

The pages dealt with the fact that the Simian virus 40 (SV40), originally exclusive to monkeys, began appearing in the polio vaccine in 1960.

“Because SV40 was not discovered until 1960, no one was aware in the 1950s that polio vaccine could be contaminated,” the website offered up as an explanation.

How the vaccine came to be contaminated, the CDC explained, was by sheer accident:

Soon after its discovery in 1960, SV40 was identified in polio vaccine. It was found in the injected form of the vaccine (IPV), not the kind given by mouth (OPV). At that time, rhesus monkey kidney cells, which contain SV40 if the animal is infected, were used in preparing viral vaccines.

The vaccine was discovered to contain the monkey cancer virus in 1960, but the “existing polio vaccine stocks were not recalled and were used until 1963,” meaning the CDC was, for a period, consciously dispersed vaccines known to have a possible link to cancer, including to tens of millions of people in other countries, such as the UK, Australia, and the former Soviet Union.

The SV40Foundation.org website details how the vaccine continued being used even after a possible cancer-link was found.

Upon the discovery that SV40 was an animal carcinogen that had found its way into the polio vaccines, a new federal law was passed in 1961 that required that no vaccines contain this virus. However, this law did not require that SV40 contaminated vaccines be thrown away or that the contaminated seed material (used to make all polio vaccines for the next four decades) be discarded. As a result, known SV40 contaminated vaccines were injected into children up until 1963.

In 2004, Michele Carbone, a scientist at the Loyola University Medical Center in Chicago, also discovered that the Soviet polio vaccine may have been contaminated even after 1963, possibly until the early 1980s, according to a report from the New Scientist.

“The vaccine was almost certainly used throughout the Soviet bloc and probably exported to China, Japan and several countries in Africa. That means hundreds of millions could have been exposed to SV40 after 1963,” the report stated.

Members of the U.S. military and several study volunteers were also exposed to the SV40 contaminated vaccines. The now-redacted FAQ asked:

Were any other people in the United States possibly exposed to SV40-contaminated vaccines?

Yes. SV40 was a contaminant of respiratory syncytial virus given to a few volunteers in an experimental study of infection with the live virus (Shah and Nathanson, 1976). In addition, SV40 was also found in adenovirus vaccines given to more than 100,000 young men in army camps in the 1950s and 1960s to protect them from respiratory infections (Sherwood et al., 1961).

The FAQ goes a long way in reassuring that “The majority of scientific evidence suggests that SV40-contaminated vaccine did not cause cancer,” but then backtracks, “however, some research results are conflicting and more studies are needed.”

After mentioning a host of studies which found no cancer link to the SV40-contaminated vaccine, the FAQ section regarding the possible health effects of the vaccine concludes more study is needed.

“…research is needed that focuses on the long-term consequences of SV40 exposure, as some cancers like mesotheliomas typically occur later in life and would not have been detected in several of the studies described above. Moreover, additional studies are needed which focus on the potential long-term effect of SV40 exposure on health outcomes other than cancer (Strickler and Goedert, 1998).”

“The SV-40 virus is now being detected in tumors removed from people never inoculated with the contaminated vaccine, leading some to conclude that those infected by the vaccine might be spreading SV40,” Dave Mihalovic, a writer for the natural health news website Prevent Disease, reported.

Indeed, information regarding SV40 contamination has been widely known for years. The question here is: why has the CDC decided to nix pages dealing with this blatantly obvious (possibly intentional?) snafu at the hands of the U.S. government?

Mihalovic would also like to know “…how many other viruses and toxins are within current day vaccines that we’ll only find out about in a few decades?”

Content of the original CDC page:

Cancer, Simian Virus 40 (SV40), and Polio Vaccine Fact Sheet

  • SV40 is a virus found in some species of monkey.


  • SV40 was discovered in 1960. Soon afterward, the virus was found in polio vaccine.


  • More than 98 million Americans received one or more doses of polio vaccine from 1955 to 1963 when a proportion of vaccine was contaminated with SV40; it has been estimated that 10–30 million Americans could have received an SV40 contaminated dose of vaccine.


  • SV40 virus has been found in certain types of cancer in humans, but it has not been determined that SV40 causes these cancers.


  • The majority of scientific evidence suggests that SV40-contaminated vaccine did not cause cancer; however, some research results are conflicting and more studies are needed.


  • Polio vaccines being used today do not contain SV40. All of the current evidence indicates that polio vaccines have been free of SV40 since 1963.

Additional Facts

  • In the 1950s, rhesus monkey kidney cells, which contain SV40 if the animal is infected, were used in preparing polio vaccines. Because SV40 was not discovered until 1960, no one was aware in the 1950s that polio vaccine could be contaminated.


  • SV40 was found in the injected form of the polio vaccine (IPV), not the kind given by mouth (OPV).


  • Not all doses of IPV were contaminated. It has been estimated that 10–30 million people actually received a vaccine that contained SV40.


  • Some evidence suggests that receipt of SV40-contaminated polio vaccine may increase risk of cancer. However, the majority of studies done in the U.S. and Europe which compare persons who received SV40-contaminated polio vaccine with those who did not have shown no causal relationship between receipt of SV40-contaminated polio vaccine and cancer.
