Virus Enzyme Found in MMR Vaccine

BACK TO THE FUTURE: Following is an article from TVR’s historical archives published in the November/December 1995 print edition. 

Swiss scientists have reported finding an enzyme, reverse transcriptase, in the live measles and mumps vaccine, which has been traced back to chickens whose cells are used to create the vaccines.1 Reverse transcriptase (RT), which copies RNA into DNA, has also been detected in yellow fever and some influenza vaccines prepared in chicken embryo cells.

Scientists Puzzled

RT activity is associated with the presence of retroviruses, a class of viruses that can permanently alter the genes of the cells they infect. AIDS is a retrovirus. Scientists at Merck & Co., the US manufacturer of MMR vaccine, are reportedly trying to find out where the RT came from. One possibility is that the RT activity in MMR vaccine signals the presence of an avian leucosis virus (AVL), a retrovirus that infects some birds and can cause a leukemia-like illness.

Another possibility is that the chickens used to make the vaccine carry RT coding genes derived from retroviruses that infected the species tens of thousands of years ago.

CDC Says to Keep Vaccinating

The RT activity in MMR vaccine was detected by Swiss scientists using advanced testing technology called product-enhanced reverse transcriptase (PERT). The Centers for Disease Control and Prevention (CDC) responded to the report in the Dec. 9, 1995 Washington Post2 about the Swiss discovery by stating that, “The World Health Organization has reviewed these findings and has concluded that these vaccines should continue to be used to prevent the diseases against which they are directed.”

The CDC maintained that, “The likeliest explanation for finding reverse transcriptase activity is that, in the distant past, an avian retrovirus integrated itself into the ancestors of the chickens that laid the eggs that were used to produce the chick embryo fibroblasts used for vaccine production… However, studies to date have not detected any evidence of a virus which can be transmitted to and replicate in humans.”

Do Chicken Viruses Belong in Humans? Independent researchers have started to express concern that using animal tissues for production of human vaccines, especially live vaccines such as MMR and polio, could be facilitating the inter-species transfer of viral infection from animals into man causing as yet undetected and unevaluated negative health effects on humans. Of particular concern is the fact that transfer of the whole animal virus into man does not have to take place in order for latent viral infection and genetic change to occur. If portions (genes) of animal viruses are introduced into humans, they have the potential to interact differently with each individual’s immune system and DNA and cause disease

    1. Historically, in the year of 1917 to be exact, John D. Rockefeller Sr., Andrew Carnegie, and J.P. Morgan began to take over all of the “teaching” hospitals of medicine. By the late 30’s to early 40’s they had complete control of what was published in the medical text books and hence what was actually taught in “western” medical universities.

      If you really desire to know the truth it will sadly, not be from the dribble in the textbooks you are currently reading. You WILL need to “step outside the box” and learn it on your own from this web site and others like this (another that I can think of instantly is the Weston A. Price Foundation web site).

  1. Scientists Puzzled!! Not surprised. Seems Barbara is too. AIDS in not a virus! Regardless, RT was thought to be a unique property of HIV when Robert Gallo was doing his closed lab, non-reproduceable, non-peer reviewed study of the retrovirus LAV he “borrowed” from Luc Montagnier, which finally was dubbed HIV. It is not. All RNA viruses share that property. But during Nixons Cancer Virus Program (1971 – 1976+-) in which many CDC scientists and others were involved in studying retro-viruses, also known as associated or passenger virus, as the catalyst of aneuploidy in cells, it did not pan out. The Rous chicken virus, an RNA retrovirus, has been believed to cause benign tumors in chickens and the thought was, possibly they could in humans. Doesn’t happen. The project ended. No huge funding forthcoming for CDC/NCI etc…

    “Of particular concern is the fact that transfer of the whole animal virus into man does not have to take place in order for latent viral infection and genetic change to occur.”
    There is no such thing as latent viral infection when referencing retroviruses. Anthony Fauci would like you to believe there is. No, they are harmless and the human body makes and discards millions of them everyday. They are RNA viruses so small as to be incredibly hard to isolate. Thats why CDC embraced PCR detection which is not verification of any whole endogenous virus but can find tiny fragments of RNA and DNA from many different pathogens indicating past infections, or just cellular debris. HIV under Gallo or anyone else since, has never been isolated in the classical sense of finding millions of whole viral particles in the blood during infection. Or passed Kochs Postulates. And real DNA virus (HPV, HSV, flu) infect the host typically within 5 to 10 days with tell tale symptoms, and, destroy the cells to replicate. But that disrupted Gallos claim of a latent virus, a retrovirus, causing the complete destruction of the human immune system, or at least that was the lie in the mid to late 1980’s. Can’t happen. AZT, a banned chemo drug from the 60’s deemed “too toxic for treatment” however did destroy the immune system and killed many gay men who took it in the first years of, “HIV – The Virus That Causes AIDS” – We’re all going to die” campaign in full swing by 1985. Nope RNA viruses are likely harmless between species as they are harmless to the host.

    1. The level of misinformation in this post is nauseating. Are you seriously going to sit there and say retroviruses are harmless? Bovine leukemia virus, murine leukemia virus, human T-cell leukemia-lymphoma virus and HIV…all known to cause cancer in the host. Harmless between species? The murine leukemia virus in humans, XMRV causes prostate cancer in humans. HIV originated from SIV. There is no such thing as latent viral infection when referencing retroviruses? HIV can remain latent for 8-10 years, HTLV-1 can remain latent in T-cells without killing them and still cause neurological disease- HTLV-1 associated myelopathy/tropical spastic parapersis. A retrovirus causing the complete destruction of the human immune system was the lie in the mid to late 1980’s? HIV damages the immune system, that is how AIDS was in fact defined; HIV plus one of 20 coinfections and CD4 counts below 200. Those suffering from AIDS are prone to otherwise rare opportunistic infections such as kaposi sarcoma, pneumocystis pneumonia, babesiosis, cytomegalovirus, HHV-6, spirochete, bartonella etc, all due to immune dysregulation…aka the complete destruction of the immune system…by HIV. In the first years of HIV a lot of people died because the disease was poorly understood. Those with AIDS were treated only for the coinfections, but the damage to the immune system was already done. Now, antiretroviral therapy begins when HIV is recently acquired, this prevents HIV from replicating and integrating into tissue reservoirs of the monocyte and macrophages. Magic Johnson had the courage to trust in science and began this novel therapy at the time. The fact that he continues to be in good health 27 years later was magical thinking in the early 90’s.

  2. “CDC Says to Keep Vaccinating” after scientists reported finding an enzyme, reverse transcriptase, in the live measles and mumps vaccine. The enzyme is associated with the presence of retroviruses, a class of viruses that can permanently alter the genes of the cells they infect. AIDS is a retrovirus.

    Romaine Lettuce was contaminated. CDC told Americans throw it away and to clean refrigerators where romaine had been stored. At that time, no deaths had been reported.

    I understand taking the lettuce off the market and cleaning away the e-coli, but why is everything taken so seriously, except deaths and illnesses possibly related to vaccines?

  3. Merlene, it is easy to look up on Wikipedia. Obviously your text book is wrong. Here it is :
    The MMR vaccine is a mixture of live weakened viruses of the three diseases. The MMR vaccine was developed by Maurice Hilleman. It was licensed for use by Merck in 1971. Stand alone measles, mumps, and rubella vaccines had been previously licensed in 1963, 1967, and 1969 respectively.
    MMR vaccine – Wikipedia
    The schools for medicine obviously teach their students wrong. Sad.

  4. Anthony Williams (Medical Medium) has already stated this in his book. There are a whole host of viruses out there now due to vaccines and eggs from the chickens.

  5. Why would anyone trust the A.M.A. , F.D.A., C.D.C., U.S.D.A. and big pharma? What have they done for the average American ? They have given us- the highest infant deaths mortality. No liability for vaccine injury , the vaccine court (a joke), makes U.S. tax payers pay settlements, they do no testing or reporting to congress ( no quality control for 32 years. ) the sickest generation ever, the first generation not to outlive there parents. autism, doing nothing for the outbreak of autism. not to mention constantly working against our immune system & the whole opiod thing .

  6. Viruses are not alive or dead so how can vaccines contain live viruses? they can’t and they don’t, the entire concept is a HOAX! Prove a so called “virus” infects or kills? show a single “isolated virus” can’t do any of the mentioned above because viruses are just particles and no one really knows what they are or if they do any harm. Please people un-brainwash yourselves!!!!

  7. Jay, Dr. Judy Mikovitz PHD would more than likely disagree with your assertion that, “Nope RNA viruses are likely harmless between species as they are harmless to the host.” You state they are likely harmless, Hmm? Not in fact, they are harmless and here’s why and here’s the replicable unbiased science without COI. That I’d like to see to Believe you over Dr. Mikovitz, who I know is qualified, a WHISTLEBLOWER on top of it & has been punished by the Mainstream/Western Medicine/DOJ/Academia for her exposing the TRUTH concerning retro-Viruses. She also states AIDS is a retro-virus just as SV40 is a Retro-Virus and Dr. Maurice Hillleman confirms these retro-viruses are in Vaccine and they are a DANGER to humans (a Merck top scientist that put the SV40 & AIDS retro-viruses in Vaccines & knew it). Here’s a link to him admitting this.
    A link to Mikovitz discussing retro-viruses…
