Aluminum in the human brain leads to age-related brain diseases. Not autism. There is definitely a link between Mercury and autism. Aluminum leads to alzheimer's, dementia, and Other diseases later in life. Aluminum as an element by itself is not found in nature. It is almost always part of another compound, and at the very least oxidized. Therefore our body has no defense against it, or evolutionary method of dealing with it. To pretend or suggest that injecting it into the bloodstream of an infant in particular is okay is the type of lunacy. This goes for many of the adjuvants found in vaccines. There is also glyphosate in most vaccines, which is a carcinogen. Mercury is still in the flu shots, and there are a host of other Highly Questionable and suspect adjuvants in almost every shot commercially available today. Many people from the baby boomer generation developed cancer as a result of a virus that was in the polio vaccine. And before you start complaining about the efficacy of the polio vaccine, look at the statistics. Polio was on the way out before the vaccine was invented, much less implemented. Vaccines, like so many things in our world today are the results of unrestrained Corporations relentlessly chasing the bottom line. With little or no thought to the consequences, health, or any other ramification affecting the General Public.
