GreenMedInfo Abstract
Slow CCL2-deendent translocation of biopersistent particles from muscle to brain
“alum has high neurotoxic potential and administration of continuously escalating doses of this poorly biodegradable adjuvent in the population should be carefully evaluated by regulatory agencies since the compound may be insidiously unsafe.”

Aluminum-induced entropy in biological systems: implications for neurological disease
Aluminum adjuvents added to vaccines are “insidiously unsafe” and may cause long-term cognitive defects. Cumulative doses of aluminum from vaccines can induce long-term cognitive deficits such as encephalopathy (brain swelling) and degenerative dementia.
