This blog entry will chronicle all the new works and/or information pertaining to the topic. Part of my work in AutismRawData is to keep up with and maintain the "Validation" blog entries such as this. The latest data will be posted at the top. Most pro-vaccine debaters defend the use of aluminum in vaccines because it is so prevalent in our environment. We consume aluminum in our food and water, but what they do not explain is that only 0.3% of oral consumption is absorbed through the gastrointestinal tract (Medscape, 2012). When aluminum bypasses this system there is a much higher rate of absorption and accumulation of this neurotoxic substance. Intravenously infused aluminum leaves behind 40% in adults and 75% in neonates (Medscape, 2012). Specific science regarding vaccine aluminum adjuvants are listed below.
