Chilling Evidence: Vaccine Linked to Cancer

If you received a polio vaccine — and who didn’t? — you may have been exposed to a virus that turns normal cells into cancerous ones.

Even worse, the infection may mysteriously be passed on to your children and grandchildren.

Mass vaccination campaigns of the 1950s and 1960s are now suspected in thousands of deaths per year via a cancer-causing virus contained in the early polio vaccines. But this doesn’t mean you’ll get cancer for sure. Keep reading and I’ll explain.

Researchers discovered this deadly vaccine tragedy in 1994 — when Dr. Michele Carbone found the SV40 virus in 60 percent of lung cancers (mesotheliomas) studied, 33 percent of osteosarcoma bone cancers and 40 percent of other bone cancers.

Virus From Monkeys

Known as SV40, this virus came from dead monkeys whose kidney cells were used to culture polio vaccines. More than 98 million people in the U.S., plus more in other countries, were exposed to the contaminated vaccine.

And it appears there’s a link to you, even if you were not vaccinated. Because the famous polio vaccine turned out to be a medical marvel with a deadly glitch.

The polio virus has been around forever. Yet the virus didn’t cause paralysis until sometime in the late 1800s. In fact, 95 percent of polio cases occur without symptoms. Most victims just get a mild fever. But in a tiny fraction of 1 percent of victims, the virus penetrates the blood-brain barrier to cause paralysis or death. People became terrified of the disease.

At the height of the polio epidemic in the early 1950s, the first polio vaccines were cultured in monkey tissue. The vaccine was rushed to market and made mandatory because of government panic and public hysteria. From the beginning there were cries of foul, accusations of poor manufacturing controls and even questions about whether it prevented polio very effectively.1

In the late 1950s, the monkey tissue was found to be contaminated with a virus that could be linked to cancer and other serious diseases. It was too late; millions had received it.

Bernice Eddy, Ph.D., of the National Institutes of Health (NIH), discovered that 70 percent of hamsters injected with kidney cell cultures containing SV virus died without apparent cause. She later discovered that tumors could be passed easily from one animal to another over a long time period. 2 The virus was dubbed SV40, meaning simian virus number 40.

Polio Vaccine Cover-Up

Eddy went public with her discovery and enraged her boss at the NIH. He tried everything he could to marginalize and discredit her — viewing her findings as a direct threat to his career and a public health policy he staunchly supported.3

In June 1961, a letter from a colleague to the Surgeon General detailed how Eddy’s work was muzzled and repressed.4

Meanwhile, by 1960 the Salk vaccine had been administered by injection to half the American public. But there was a rival vaccine — the oral vaccine developed by Sabin. By mid-1960, 60 million Russians had received Sabin’s oral vaccine (OPV) in field trials. It was pronounced a huge success.

A group of Merck scientists led by Dr. Maurice Hilleman eventually proved both the Salk and Sabin forms were contaminated with SV40. But the government kept this under wraps, warning neither doctors nor the public, while the vaccines continued to be given for years.

SV40 is so virulent, it became a popular tool of cancer researchers awed by its ability to transform healthy animal cells into tumor cells. This tiny but mighty life form can completely disrupt cells, cause them to lose control of themselves and reproduce wildly.

Finally, in 1994 Dr. Michele Carbone autopsied dead research animals to make a shocking discovery: SV40 was linked to the rare malignant mesothelioma — as well as to brain cancer and osteosarcoma (bone cancer). This research found that SV40 causes mesothelial cells to become malignant 1,000 times faster than fibroblasts.5 Between 1997 and 2003, 25 new published studies showed the presence of SV40 in mesotheliomas while 16 others found SV40 in brain, bone and other cancers.6

In fact, one study showed the presence of SV40 infections in children born after 1982 — decades after the polio vaccine was supposedly cleaned up.78 Researchers do not understand why SV40 is still spreading.

Vaccine Revelations

Dr. Maurice Hilleman — head of Merck’s vaccine program, developer of more than 36 vaccines and recipient of a special lifetime achievement award from the World Health Organization — made shocking revelations before he died about Merck’s responsibility in unleashing the SV40, as well as the AIDS virus.9

He also testified that the government kept SV40 contamination a secret to avoid public hysteria:

  • Documents now conclusively prove that SV40 was never removed from the vaccine stocks after 1963. SV40-tainted seeds were never thrown away. They were used in OPV (oral polio vaccine) for millions of children for nearly four decades.10
  • SV40 appears in 61 percent of all new cancer patients, including patients too young to have received the vaccine 40 years ago.11
  • SV40 can be transmitted sexually and through blood transfusions.12
  • Ten percent of those never exposed directly to tainted vaccines test SV40-positive.
  • Lancet published clear evidence that tainted polio vaccine is responsible for nearly half of the 55,000 non-Hodgkin’s lymphoma cases per year.13
  • People from States receiving high-SV40 OPV now get osteosarcoma tumors at 10 times the rate of those with SV40-free lot numbers.14

Scientific Integrity Or Government Cover-Up?

Not to sound like a conspiracy theorist here, but consider:

  • When research went public in 1999, NCI declared there’s “no evidence of human cancer linked to SV40.” But other researchers contend that SV40 had already shown up in a wide variety of tumors — the highest rates in those receiving tainted OPV. Maybe that’s not proof it’s the cause, but it certainly qualifies as a statistical link. And, in the science of identifying causes of cancer, correlations like this have long been considered evidence of probable cause.
  • The government and NIH have denied requests for grants to study SV40. Why?
  • Government denies a cancer link because of “those who are too young to have received the vaccine in the 1950s,” ignoring the potential of transmission via “shedding” (passing the virus to non-vaccinated people) — something the vaccine was specifically designed to do.

Despite the government’s foot-dragging, SV40 is one of the most widely studied viruses in all of microbiology. During the past 40 years, SV40 has been widely studied and well understood. More than 3,400 scientific articles name SV40 in their title, and more than 15,000 articles mention SV40. SV40 has been routinely used to create human cancers in the lab and to test cancer therapies.15 Moreover, it’s now known how this virus causes cancer on a molecular level. And experts in SV40 research finally announced SV40 is a class 2A human carcinogen.16

Not Everyone Who Received SV40 Gets Cancer

There is hope even though nearly every baby boomer received these vaccines 40 or 50 years ago and, sadly, we can’t turn back the clock for a do-over. However, even Carbone, a leading SV40 expert, says the virus probably doesn’t cause cancer all by itself, “… you need many different carcinogens, because different carcinogens do different things. Cancer is a multifactorial process.”

In other words, no individual factor can create cancer in isolation. Instead, your cells require numerous hits (insults) from various carcinogens to start cancer development.

But Carbone does consider SV40 one of the most potent human carcinogens. He also goes on to state that cellular changes in your body (unlike a test tube) are influenced by the status of your immune system. A healthy immune system generally seeks and destroys invading viruses.

So, to decrease your personal risk, you can engage in strategies known to enhance your immune system:

  • Eat a mostly raw, organic, high-enzyme diet rich in vegetables and free of sugar, artificial sweeteners and carbs.
  • Take supplements that boost your immune system.
  • Reduce calories, lose weight and exercise daily.
  • Control stress.
  • Give thanks for your daily blessings.
  • Detoxify yourself, your home, yard and life as much as possible.

So, to decrease your personal risk, you can engage in strategies known to enhance your immune system: It does appear there’s damaging evidence about polio vaccines, but we may never be 100 percent sure about all of its ramifications. All the same, what’s done is done. Move forward confidently with strategies known to reduce your risk. And at the same time, be wary and don’t repeat the mistakes of the past.
