This article is a good read about XMRV and other retroviruses and the diseases they may cause or do cause:
Researchers have known for quite some time now that retroviruses are present in certain vaccines. Vaccines are a multibillion dollar industry.
In 1996 the Swiss National Center for Retroviruses questioned the safety of live-virus vaccines. This organization found certain live chicken-cell derived vaccines (such as the MMR vaccine) contaminated with avian (bird) retroviral particles. However, they were not sure at that time whether or not these retroviral particles would cause disease in humans. (4) What they had concluded in 1996 was that they did not know if using chicken cells for vaccine manufacturing was safe or not.
Some readers are unfamiliar with the fact that most vaccines are currently cultured in eggs. In my last article entitled, FDA Approved H1N1 Vaccines Contain Ingredients Known to Cause Cancer and Death I conclusively show that vaccine manufacturers are using chicken eggs to produce the current H1N1 vaccine. Will the FDA and CDC test the novel H1N1 vaccine to insure retroviruses are absent? It seems that there would be a real possibility they would be present in the vaccine, does it not?
When you inject foreign ingredients, such as bovine serum (cow blood), monkey kidney tissue, chick kidney cells, human serum albumin (protein from human blood), mouse serum protein (protein from mouse blood), or MCR-5 (cells from aborted fetal tissue) directly into your arm or thigh, what exactly are the side effects? (6) Does it make you healthier? We are assured that it does.
Perform a thorough search online (to include peer-reviewed medical journals) for any type of chronic disease that you are wondering about. Make sure that you include the word retrovirus in that same search field. You will be amazed that retroviruses have been implicated in or have even proven to cause many different diseases. Search further to discover that there are countless articles in these same peer-reviewed medical journals involving vaccine research and development in the area of you guessed it retroviruses. The madness doesnt stop there because gene therapy is also being studied. So, what does the scientific community know and what arent they telling the public?
