- Note - As was postulated over 10 years
ago by Dr. Robert Strecker, MD, and most currently by Dr. Len Horowitz,
the early polio vaccines were known to be hopelessly contaminated with
SV-40 which has caused the death of millions of people via brain, kidney,
and other cancers. The following story is yet more evidence supporting
- THE mass vaccination campaigns of the
Fifties and Sixties may be causing hundreds of deaths a year because of
a cancer-causing virus which contaminated the first polio vaccine, according
- Known as SV40, the virus came from dead
monkeys whose kidney cells were used to culture the first Salk vaccines.
Doctors estimate that the virus was injected into tens of millions during
mass vaccination campaigns before being detected and screened out in 1963.
Those born between 1941 and 1961 are thought to be
- most at risk of having been infected.
- Now a new study of the effects of SV40
points to disturbing evidence that the monkey virus
- causes a number of human cancers. It
concludes that there is "compelling" evidence linking SV40 to
mesothelioma, a once-rare type of lung cancer whose prevalence is rapidly
- Dr Janet Butel of the Baylor College
of Medicine, Texas, and the lead author of the study, told The Telegraph:
"I feel strongly that research is warranted to determine how common
human infections by SV40 may be, and what factors might predispose individuals
to SV40-related tumours." Her study, published in the Journal of the
National Cancer Institute, also suggested that the monkey virus may be
passing from those given the contaminated vaccine to their children, spreading
the cancer risk still further.
- Blood samples analysed by Dr Butel and
her colleagues point to the steady spread of the
- cancer-causing virus in the human population,
with 10 per cent of those never exposed directly to the contaminated vaccine
- positive for SV40. Dr Butel said: "I
- SV40 is present in the human population
today and is being spread among individuals by an unknown route."
- The Telegraph has learnt that scientists
in Britain have joined an international effort to confirm the findings.
According to Prof Gordon McVie, the director general of the Cancer Research
Campaign, researchers have so far uncovered evidence linking SV40 to a
number of cancers, including brain tumours and bone
- cancer. He said: "I've a feeling
that the virus might be implicated in more, such as non-Hodgkin's lymphoma
and prostate cancer."
- The study is also likely to prompt a
- rethink by doctors of what happened 40
- ago, during the early days of polio vaccination.
Until now, SV40 was regarded as harmless, with no evidence of long-term
health effects emerging in follow-up studies of those vaccinated.
- Now it appears that these studies may
not have been conducted over a long enough period. New highly sensitive
laboratory tests have disclosed the presence of SV40 in many different
types of human tumour.
- The most startling results centre on
mesothelioma, until recently linked primarily to exposure to asbestos.
Studies have found that around 70 per cent of mesothelioma cases test positive
for the SV40 virus. Over the past 30 years, the number of mesothelioma
cases has risen 10-fold, to about 1,000 a year, and is
- predicted to reach 4,000 early next century.
- Until now, the increase was blamed on
the asbestos industry. But the new findings are leading scientists to suspect
that SV40 may account for a substantial number of mesotheliomas. Dr Butel
said: "The consistent association of SV40 with that tumour is compelling."
- Some scientists remain sceptical of the
link, however. Robin Weiss, a professor of viral oncology at University
College, London, said
- that SV40 is widely used in laboratories
- could easily contaminate tumour samples,
fooling the ultra-sensitive tests used to detect the virus. Prof Weiss
said: "Many of the positive results are probably false positives.
We've looked at mesothelioma and did find it in some cases, but then we
got bogged down in whether they were due to contamination or not."
- However, Dr Bharat Jasani, a leading
expert on SV40 and mesotheliomas at the University of Wales College of
Medicine, Cardiff, said that new reliability tests rule out contamination
as a possible explanation. He said: "There is absolutely no question
of laboratory contamination being to blame. That part of the story is now
over. The time has come where we have to take things more seriously."
- Dr Jasani said he had little doubt that
the mass polio vaccination campaigns were to blame for SV40 entering the
human population. He said,
- however, that this could bring new hope
to hundreds of cancer patients, as it suggested that many might be treated
by a vaccine that attacked SV40. He said: "We could think about saving
more than 2,000 lives a year from mesothelioma - and that is good news."
- A spokesman for the Department of Health
said last night that it was aware that SV40 had contaminated early polio
vaccines but insisted that there is no evidence that the virus caused tumours.
She said: "It is also important to stress that the vaccine currently
used is rigorously checked for safety and efficacy and is free of SV40."
