Further to my comment above, I’ve done some more searching, and Voila!:
‘Vaccine Ethylmercury vs. Methylmercury’: http://whale.to/vaccines/ethyl_vs_methyl.html
‘World Mercury Project Thimerosal, a mercury-containing preservative, is still in 48 million U.S. flu vaccines each year, tetanus toxoid, meningococcal vaccines and, in massive doses, in the pediatric vaccines given to 100 million children across the developing world. A Centers for Disease Control (CDC) review published last month found that the ethylmercury in thimerosal is as profoundly neurotoxic as the heavily regulated methylmercury in fish.
”I had no clue about the pivotal role they both had played in deceiving the public about thimerosal safety. Both of them spoke to me willingly. Offit expressed admiration for my father, which is an effective way to butter me up. I asked them both the obvious question: “Why do we advise pregnant women to steer clear of fish because of neurotoxic mercury and yet inject much larger doses of mercury into pregnant women and babies?” They both repeated to me the thread worn industry canard that the “ethyl mercury in vaccines is not as dangerous as the methyl mercury in fish” which everyone admits is highly neurotoxic. Offit explained to me that ethyl mercury wasn’t toxic because it leaves the human body so quickly.
By then, I’d read Burbacher’s monkey studies which confirmed Offit’s assertion that the ethyl mercury from vaccines rapidly left the blood. But, Burbacher had shown the ethyl mercury was not being excreted from the body as Offit implied during our telephone conversation. Instead, it was going directly into the brain, where it rapidly metabolized into highly toxic inorganic mercury, and then lodged there, creating inflammation and brain damage. Burbacher had shown that inorganic mercury remains in the brain for years. Instead of being evidence of its safety, as Offit represented, ethyl mercury’s penchant for disappearing quickly from the blood was testimony to its extreme peril; it was disappearing due to the ease with which it crossed the blood-brain barrier! Ethyl mercury used in vaccines was both far more persistent and far more toxic than the methyl mercury found in fish. The Guzzi study, in 2012, showed the ethyl mercury was 50 times as toxic to cells. When I mentioned the Burbacher study to Stratton and Offit, they both went silent. It was obvious that they were aware of the study. THEY BOTH KNEW that science had refuted what they were telling me. They were accustomed to talking to journalists who seem to have an allergy to reading science and were content to parrot their reassurances.” [2016 Dec] Mercury, Vaccines and the CDC’s Worst Nightmare By Rita Shreffler…’
