(NaturalNews) A pair of former Big Pharma scientists have accused their former employer, Merck & Co., of falsifying tests of an exclusive mumps vaccine in recently filed court papers, charges they say the pharmaceutical giant has yet to answer.Lawyers at Constantine Cannon, the firm representing the scientists, have asked U.S. Magistrate Judge Lynne Sitarski of the Eastern District of Pennsylvania to force the company to respond to their request for discovery, which seeks to compel the company to provide efficacy data regarding the vaccine in the form of a percentage.But, as Reuters reports, rather than answer the question, the letter said, Merck has instead been evasive, using "cut-and-paste" stock answers and claiming that the company cannot run new clinical trials to determine current efficacy. Rather, Merck has only provided data that is five decades old."Merck should not be permitted to raise as one of its principal defenses that its vaccine has a high efficacy, which is accurately represented on the product's label, but then refuse to answer what it claims that efficacy actually is," the court letter said.A representative of Merck could not immediately be reached for comment, Reuters noted in its June 4 report.The news service added:In 2012, Chatom Primary Care, which is based in Alabama, and two individual physicians – all buyers of the Merck mumps vaccine – filed a proposed antitrust class action based on allegations in the whistleblowers' suit. The two cases are now being coordinated before Sitarski and U.S. District Judge C. Darnell Jones, said Reuters.As noted byeditor Mike Adams, the Health Ranger, in this June 2012 report , Merck knowingly falsified its mumps vaccine test data, spiked blood samples with animal antibodies, sold a vaccine "that actuallymumps and measles outbreaks, and ripped off governments and consumers who bought the vaccine thinking it was '95% effective.'"As further reported byat the time:Merck's allegedly fraudulent claims were made so that the company could corner the mumps vaccine market, Adams noted, adding that the Merck scientists – who are virologists – state the fraud has been ongoing since the 1990s.But there is even more complicity, as Adams pointed out:In its court filing Chatom alleged:In a separatereport, Rosemary Mathis, Vice President of Victim Support, SANE VAX, INC., pointed out that governments all over the world were defrauded by Merck after purchasing the vaccine. What's more, the dishonesty has actually led to more calls for more vaccines."According to the two whistleblowers, not only have all the multivalent MMR vaccines been sold under false pretenses, but, as a result of this LACK OF EFFICACY, there have been numerous mumps outbreaks worldwide prompting calls for regular MMR boosters throughout life," she wrote.In 2013, Adams wrote that Merck's epic failure and cover-up led to a greater number of outbreaks because the vaccines were "designed to fail.""Measles and mumps are making a huge comeback in the United States, but doctors and journalists all make the same critical error in understanding why. They blame 'parents who don't vaccinate their kids' as the cause, but the real cause -- as revealed by whistleblowing scientists working for top vaccine manufacturers -- is that measles and mumps vaccines arefrom the start," he wrote."Scientific fraud, it turns out, is an inherent part of the vaccine industry."
