The aluminum hydroxide used in many vaccines has been linked to symptoms associated with Parkinson's, ALS, and Alzheimer's.
Aluminum hydroxide, which stimulates immune response, has been used for 80 years in vaccines such as those for hepatitis A and B, and the Pentacel cocktail for diphtheria, pertussis, tetanus, polio, and meningitis.
Scientists discovered the link after injecting mice with an anthrax vaccine developed for the first Gulf War. After 20 weeks, a fifth of the mice developed a skin allergy, and memory problems increased by 41 times compared to a placebo group. Also, inside the brains of mice, 35 percent of the cells that control movement were destroyed.
U.S. drugmakers are currently testing aluminum hydroxide as an additive in flu shots, even though a recent study of the efficacy of avian flu vaccine found that it only worked roughly 50 percent of the time, and then only at a dose roughly 12 times what is typically given for a seasonal flu vaccine.
