- Aluminum adjuvant and Autism
It is not proved yet. The newest paper (Crepeaux et al.) by the Gherardi research group in France itself says “In the context of massive development of vaccine-based strategies worldwide, the present study may suggest that aluminium adjuvant toxicokinetics and safety require reevaluation.”
They don’t say “suggest”, but “may suggest”.
In addition, there are many counter arguments and papers with different conclusions. Some are below.

“This is a transcripts of a meeting/conference. Is the result pubulished on a reviewed journal? If not, it is just there is a doctor that he found statistically significant relationships between aluminum in vaccine and autism. In addition, there are many other statistical studies saying there is no relationships between vaccine and autism.”
Aluminum adjuvant linked to Gulf War illness induces motor neuron death in mice.

Neuromolecular medicine, 2007
Quoted from :
“A small study that was never replicated, has nothing to do with autism, and was done on mice. How very not at all fascinating. But it has “aluminum adjuvant” in the title, so goodness knows it simply must be included on this list.”

Brain IL-6 elevation causes neuronal circuitry imbalances and mediates autism-like behaviors.

Quoted from: “A “professor” who isn’t talks science about vaccines that isn’t”
“This paper is full of weasel words: like “may” and “could” and “probably” in describing the supposed mechanism for maternal immune activation giving rise to brain IL-6 and how that then leads to autism…With some added leaps from behaviours observed in mice to autism which lack credibility…”
Administration of aluminium to neonatal mice in vaccine-relevant amounts is associated with adverse long term neurological outcomes.
CA Shaw, Y Li and L Tomljenovic, Journal of inorganic biochemistry, Nov 2013
Quoted from
“basing a paper on the ecological study #13, which as we know is incredibly weak. Anyway, this is a study on mice given “high” or “low” doses of subcutaneous aluminum. They exhibit some vague differences on certain mice tests. Does this translate to humans? Hardly.”
Note: #13:Do aluminum vaccine adjuvants contribute to the rising prevalence of autism?
Quoted from
“They not only abuse statistics but also use misdirection and multiple leaps to conclusions by impling that aluminum causes inflammation, people with autism have signs of increased inflammation, and therefore aluminum may cause autism. They found a correlation, but there is no causation to be found.”

Quoted from
“Sigh. Yet another example of someone who doesn’t understand the words latching onto a few of them. You see, because the title says “microglial” and “autism”, so that must mean that vaccines cause autism. Or something like that. One major problem: there is no evidence that vaccines can induce increased microglial density.”
Slow CCL2-dependent translocation of biopersistent particles from muscle to brain.
Z Khan, C Combadière, FJ Authier, V Itier, F Lux, C Exley, M Mahrouf-Yorgov, X Decrouy, P Moretto, O Tillement, RK Gherardi and J Cadusseau, BMC medicine, Apr 2013 04
Their conclusionis “This occurs at a very low rate in normal conditions explaining good overall tolerance of alum despite its strong neurotoxic potential. However, continuously escalating doses of this poorly biodegradable adjuvant in the population MAY become insidiously unsafe, especially in the case of overimmunization or immature/altered blood brain barrier or high constitutive CCL-2 production.”
I understand the conclusion says whether continuously escalating doses of this poorly biodegradable adjuvant in the population is unsafe or not has not been proved.
Quoted from:
“Finally some real meat! A discussion on aluminum potassium sulfate (alum) and how it can persist! About time we got something I can sink my teeth into. Ok, let’s see. The researchers injected mice with alum and found that it can persist in distant organs (including the spleen and brain) for at least a year. Ok, so that means . . . nothing. Especially when they conclude that “This occurs at a very low rate in normal conditions explaining good overall tolerance of alum despite its strong neurotoxic potential”. It may be increased in an extremely small subset of the population with an anomolous CCL-2 gene. The research there is ongoing, but the authors essentially say that alum is very well tolerated. Another case where Ginger and her colleagues didn’t understand a word of what they were reading, but gosh the title sure sounds scary.”

Biopersistence and brain translocation of aluminum adjuvants of vaccines.

Frontiers in neurology, 2015
This is a review article using (cherry-picked) data to suggest that aluminum in vaccines accumulates in the brain and nervous system, causing “toxic effects.” So, I think we cannot count this paper as an independent research paper supporting their conclution, when there are many counter arguments on many of referenses they cited in this paper.

It seems the paper has got many critisism from many scientists, and one example is a published letter by D. Hawkes on Toxicology. There is no reply by the authors of the paper except for a retracted letter on the same journal.

“The study did not provide us with any significant data supporting the hypothesis (that large amounts of aluminum can cause neurological conditions in mice). The study included 36 subgroups of analysis, yet they only provided data for six of them, and the statistics for those six groups were underwhelming at best. My guess is that the other 30 groups had worse statistics.”
“Toxicology is a moderately low ranked journal, so maybe they’re desperate for articles, irrespective of scientific quality. But there is harsh commentary about the study from across the scientific world – it should be retracted.”
