The Problem with Aluminum in Vaccines
How dangerous is it to have aluminum in our vaccines? I've never heard it discussed until recently, when President Trump indicated that he would like to have aluminum removed from all vaccines.
Maryanne Demasi has written "A chat with 'Mr Aluminium': Trump’s Tylenol warning stole the headlines, but his vow to strip aluminum from vaccines was the real shock. I asked Dr Chris Exley—Mr Aluminium himself—what it would mean for the vaccine industry."
[Dr Chris Exley] has published over 200 peer-reviewed papers on the subject, showing how aluminium accumulates in the brain, how it is trafficked by immune cells, and how it may be implicated in conditions from Alzheimer’s disease to autism.
His 2018 paper revealed some of the highest levels of aluminium ever recorded in human brain tissue, including in children diagnosed with autism.
In the wake of Trump’s press conference, Exley argued that Tylenol exposure in pregnancy alone cannot explain severe, debilitating autism — and that this kind of brain damage is far more likely linked to infant exposure to aluminium in vaccines.
Exley has also been one of the most outspoken critics of the HPV vaccine Gardasil, warning that Merck’s novel aluminium adjuvant, amorphous aluminium hydroxyphosphate sulfate (AAHS), is unusually potent, biologically reactive and unsafe.
His stance has made him a target, costing him funding and institutional support, but his voice remains central to any honest debate about aluminium and vaccines.
Who is Dr. Chris Exley? This, according to Grok:
Dr. Christopher Exley is an English chemist renowned for his extensive research on the health effects of aluminum exposure in humans. He specializes in bioinorganic chemistry, focusing on how aluminum interacts with biological systems and its potential links to neurological conditions.EducationExley earned his PhD from the University of Stirling in 1989. His doctoral thesis, supervised by J. D. Birchall, examined the amelioration of aluminum toxicity in Atlantic salmon, with a particular emphasis on aluminum-silicon interactions.CareerHe is a Professor of Bioinorganic Chemistry at Keele University, where he serves as the group leader of the Bioinorganic Chemistry Laboratory. In 1994, he received a Royal Society University Research Fellowship, supporting his early career work. As of 2025, he remains affiliated with Keele University and continues to lead research on aluminum through the university's dedicated resources. Exley is also active as a public communicator, maintaining a Substack newsletter ("Dr's Newsletter") where he discusses the bioinorganic chemistry of aluminum, with recent posts as late as July 2025.
