FROM THE CDC -Simian Virus 40 (SV40), Polio Vaccine, and Cancer -- there is a link

CDC ^ | Unk.

[STARWISE]

At a glance: SV40 is a virus found in some species of monkey. Soon after its discovery in 1960, SV40 was found in polio vaccine.

Over 98 million Americans received one or more doses of polio vaccine during the period (1955-1963) when some of the vaccine was contaminated with SV40. SV40 has been found in certain types of human cancers, but it has not been determined that SV40 causes these cancers. The majority of evidence suggests there is no causal relationship between receipt of SV40-contaminated vaccine and cancer; however, some research results are conflicting and more studies are needed.

" 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).

SV40 is known to cause tumors in rodents. Have research studies found an association between SV40 and cancer in humans?

Yes. An association has been found between SV40 and certain types of cancer in humans. However, though the virus or its DNA have been found in certain types of cancer, it has not been determined that SV40 causes these cancers. Finding that two events are "associated" is not the same as establishing that one event caused the other.

SV40 was linked with mesothelioma after tumors developed in hamsters that were injected with SV40 into the lungs, heart and abdomen (Cicala et al., 1993). Mesotheliomas are rare cancers usually located in the lining of the lungs in humans and are associated with asbestos exposure. SV40 has been found in 47% to 83% of human mesothelioma tumors (Carbone, 1999). In addition, reports have documented an association between SV40 and brain and bone tumors (Jasani, 2001).

Two recent studies also found an association between SV40 and non-Hodgkin's lymphoma (Shivapurkar et al., 2002; Vilchez et al., 2002). These studies identified the virus in 42-43 percent of non-Hodgkin's tumors, while finding no SV40 in tissue from healthy study volunteers. Lymphoma is a general word for cancers that develop in the lymphatic system – the tissues and organs that produce, store and carry white blood cells that fight infection and other diseases. Hodgkin’s disease is one type of lymphoma; all others are called non-Hodgkin’s lymphoma. Lymphomas account for about 5 percent of all cases of cancer in this country (http://www.nci.nih.gov).

Have research studies looked at the risk of cancer in children whose mothers received SV40-contaminated polio vaccine?

Yes, two studies concerning maternal vaccination with SV40-contaminated vaccines and risk of cancer in offspring have been conducted. Each study reported an association.

1. Heinonen et al. (1973) reported a higher incidence of neural malignancies in children born to mothers who received inactivated poliovirus during pregnancy. The prospective study of over 50,000 women who were pregnant between 1959-1965 identified 24 malignancies in their children during the first 4 years of life. The rate of malignancy was about two-fold greater in children born to mothers immunized during pregnancy when compared with children born to unimmunized mothers or mothers who received influenza or OPV vaccines. Neural tumors accounted for most of the difference.

2. Farwell et al. (1979) found that of 15 cases of medulloblastoma in children born in Connecticut between 1956-1962, 10 were born to mothers exposed to SV40 contaminated polio vaccine while 5 were born to mothers unexposed. Interpretation of these results, however, is hampered by the low response rates and uncertain accuracy of vaccination histories by obstetricians (Strickler et al., 1998).

Additional studies are needed that focus on maternal vaccination with SV40-contaminated vaccines and risk of cancer and other health effects in offspring.

I follow health news pretty regularly, and have never heard about this, and I'm wondering why not. Anyone else heard about this ?? I don't know if this true or not, but I'm told that kidneys from diseased monkeys were used in the contaminated vaccine!!! YUCK. I think I was vaccinated for polio in the 50's or 60's, and I know my kids got the oral polio vaccine when they were youngsters in the 60's. I'm really concerned about this and what else we don't know that's in vaccines. Any knowledgeable Freepers have pertinent info?

BTTT! Please check the CDC page.

[Mr Ramsbotham]

I'm sure I received an injected polio vaccination at some point during the critical time in question. On the upside, I've never contracted polio.

[Brad’s Gramma]

Oh gee gosh goody gum drops.

Sheeeeeeeesh! If it's not one thing, it's another!!!

Thanks for the ping, STAR.

Interesting comment coming from the CDC..........Of course if it were related to SHS it would be absolute PROOF that association=casue.

Considering my husband & I are part of this group, it's food for thought (or worry???)

I remember standing in line at the local High School, waiting to get my sugar cube vaccine. I was 5 years old.

[Cicero]

I was in the army during the years specified, and got a boatload of shots. They didn't normally tell us what the shots were for, they just lined us up with our shirts off and passed us through.

So, no point in worrying about it.

There's very cutesy connection language used throughout, but then there's this, and the fact that "additional studies are needed" is used liberally throughout also:

I'd just like to know why this connection hasn't been blasted to the public. I would not have known about it, had my neighbor not told me about it, and then chastised me for getting the flu shot this year .. now I'm wondering what was in that.

Correlation is not proof. But when coorelation is all you
have, you ignore it at your peril.

So while this pithy wisdom might suggest that a smoker
find a new hobby, it's not clear what action is indicated
here. Is there a test for residual SV40 antibodies?

[STARWISE]

That's dealt with at the CDC website .. bottom line: not yet. "Blood tests can identify if a person has antibodies to SV40, but there is no test for SV40 commercially available at this time.

Research laboratories are currently refining the techniques used to detect SV40. PCR (polymerase chain reaction) assays are currently in use to detect SV40 DNA segments. Because of inconsistent results between laboratories, there is a need to develop a standard PCR assay (Levine et al., 1998)." (Love how they move so quickly on this ..)

[e_engineer]

The article said the oral vaccine was not contaminated, only the injected vaccine.

[vetvetdoug]

I received both the Salk and oral Sabin Polio vaccines. On top of that, I received the Adenovirus vaccine contaminated with the SV 40 as an USAF recruit. I learned all about the SV40 in advanced Microbiology at the University of Tennessee. One would be surprised at the number of piggyback viruses in vaccines.

[LibFreeOrDie]

Every new preventative/therapy brings new risks, many of which cannot be known when the therapy is first used.

Any time the treatment involves use of cultured tissue or extracts thereof, or body parts from organ donors, you run the risk of picking up as yet unknown contaminants, in addition to known ones.

For example, there was an article posted here a few days ago about rabies appearing in the recipients of organs from a person who had died of a heart attack. The donor had not exhibited any symptoms before death.

[STARWISE]

Wow .. you sure do have experience with it. What's your take on all this? And especially, why hasn't it been revealed in a meaningful and very public way to the American public? (I'm praying your answer isn't: lawsuits.)

[TapTheSource]

I no longer trust the CDC/NIH/(Socialist) Public Health Establisment.

Heres why...

There's very cutesy connection language used throughout, but then there's this, and the fact that "additional studies are needed" is used liberally throughout also:

And that "cutesy" language is exactly what prompted my flippant remark.

It's a said state of affairs when political correctness is what determines what the "studies" will find and when they will decide that correlation = causation and when it doesn't.

I'd just like to know why this connection hasn't been blasted to the public.

Because it is not politcally expedient for research dollars to make the pharmaceuticals companies angry. Cynical attitude on my part? You better believe it. the government approved these vaccines and while there are probably not many involved left from the era of those vaccines, it doesn't look good.

OTOH, they could actually be telling the truth this time around........but I don't trust them, not when it comes to such weak "associations." I would venture to say they are just covering all angles of their collective butts.

[STARWISE]

I'd say there's plenty of us left ... I got in the 50's or 60's and there's got to be millions of us baby boomers who got it in that timeframe.
