One of the biggest controversies raging among anti-vaccine supporters and those who still believe in being vaccinated is over the use of thimerosal. The discussion is often heated, and emotional. Some have even claimed that the CDC is hiding information linking thimerosal use to conditions like autism, while others try to debunk the claim. The mercury-based preservative is indeed still in many vaccines, but is it safe?
Merck, GlaxoSmithKline, Sanofi Pasteur, and Novartis all still manufacture vaccines, which contain mercury, or thimerosal. It is even used in an influenza vaccine given to children as young as 6 years of age. Mercury is a known neurotoxin. The FDA calls thimerosal a ‘mercury-containing organic compound . . . that has been widely used since the 1930s . . . as a preservative in many drugs, including vaccines.”
They go on to say that due to concerns over neurotoxicity, thimerosal has been removed ‘or reduced to trace amounts’ in all vaccines routinely used on children 6 and younger, with the exception of the Influenza A vaccine (see Table 1). The FDA also admits that vaccines which still contain thimerosal ‘contain only 1 microgram or less of mercury per dose’.
Mercury is a heavy metal poison. You can get mercury poisoning from many things besides vaccines – eating sushi, having mercury amalgams in your teeth, or living near a coal mine or other industrial site that pollutes the environment with mercury. You can also get mercury poisoning from vaccines.
What’s more, mercury is lipophilic, which means it concentrates where there is fatty tissue. The brain is full of fatty tissue. Most brains are a whopping three pounds of fatty tissue. This means that while mercury from any source, including vaccines, may be small, it accumulates in the body – especially in the brain. Dr. Mark Hyman presented a paper at Tulane University School of Public Health and Tropical Medicine in New Orleans, titled, “The Impact of Mercury on Human Health and the Environment.”
What he found is consistent with the fact that mercury accumulates in fatty tissues, especially the brain. Mercury in very small doses caused central nervous system toxicity:
“. . . .incuding symptoms of erethism with symptoms of shyness, emotional labili-ty, nervousness, insomnia, memory impairment, and inability to concentrate. Other CNS symptoms may include encephalopathy, peripheral neuropathy, Parkinsonian symptoms, tremor, ataxia, impaired hearing, tunnel vision, dysarthria, headache, fatigue, impaired sexual function, and depression. Renal toxicity includes proteinuria, renal syndrome, and acute renal failure. Gastrointestinal symptoms include nausea, vomiting, diarrhea, and colitis. Dermal toxicity includes allergic dermatitis, chelitis, gingivitis, stomatitis, and excessive salivation.”
If vaccine supporters really want us to believe vaccines are safe – why do they still contain a substance that can cause a laundry list of health problems?
