IntelliHub skriver att den amerikanska hälsomyndigheten Centers for Disease Control and Prevention (CDC) försökt städa undan ett dokument som visar att CDC är medveten om att poliovaccin kontaminerats av ett cancerframkallande virus, Simian Virus 40 (SV40). NewsVoice återpublicerar CDC-dokumentet.
SV40 misstänks ha orsakat miljontals fall av cancer i USA. Upp till hela 98 miljoner doser av poliovaccin kan ha kontaminerats av SV40, skriver IntelliHub.
Det undanstädade dokumentet som CDC rubricerat: ”Cancer, Simian Virus 40 (SV40)” visar också mycket riktigt att CDC konstaterar att SV40 hittats i poliovaccin.
CDC skriver att mellan 10-30 miljoner amerikaner kan ha injicerats med virussmittade poliosprutor och att mer än 98 miljoner amerikaner åren 1955-1963 vaccinerades med poliovaccin.
CDC skriver att poliovaccin varit fritt från SV40 sedan 1963.
Dokumentet som senaste uppdaterades av CDC år 2007 och som tagits ned från CDC.s hemsida är återpublicerat nedan.

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.

Bra Newsvoice att vidarebefordra detta. Hade man läst 2000-Talets Vetenskap så hade vi redan 2001: 4, sid 27 tagit upp detta genom Viera Scheibner (finns på nätet). I detta nummer:
http://www.2000tv.se/tidning/slutsalda_tidningar/2000taletsvetenskap_nr1_2006.pdf på sidan 10 ger Alan Cantwell sin beskrivning liknande den i Newsvoice artikel. Vi har också i sammanhanget med SV-40 intervjuat Måns Rosen , cancerepidemolog om sambandet. – Rena bondturen, sa han om att i Sverige så utgick man från asiatiska makaker när man framställde inhemskt poliovaccin.
Nu är det OS snart och ryssarna är hårt ansatta. Det var de också inför tidigare OS när man faktiskt testade poliovaccinet på rysk befolkning. Om detta skämtar en av de kommersiella vaccinernas fäder Maurice Hildemann i 2000-Talets spalter. USA förbättrade sina chanser i dåtida OS genom att smitta ryssarna med apvirus. Cynismen blomstrar i dessa kretsar.
