Aluminum Adjuvants

High levels of aluminum, including nanoscale particles within macrophages, have been found in brain tissue of deceased autistic individuals. After injection, aluminum adjuvants activate macrophages which then carry the aluminum across the blood-brain barrier. Aluminum is classified as a neurotoxin that typically manifests as deficits in learning, memory, concentration, and speech. The FDA sets strict aluminum limits for parenteral feeding solutions but applies no safety limits and requires no warnings for aluminum in vaccines. Aluminum adjuvants persist unexpectedly long in the human body and do not clear quickly after injection. Aluminum compounds are the most commonly used adjuvants in vaccines.
