Do aluminum vaccine adjuvants contribute to the rising prevalence of autism?
Abstract
Autism
spectrum disorders (ASD) are serious multisystem developmental
disorders and an urgent global public health concern. Dysfunctional
immunity and impaired brain function are core deficits in ASD. Aluminum
(Al), the most commonly used vaccine adjuvant, is a demonstrated
neurotoxin and a strong immune stimulator. Hence, adjuvant Al has the
potential to induce neuroimmune disorders. When assessing adjuvant
toxicity in children, two key points ought to be considered: (i)
children should not be viewed as "small adults" as their unique
physiology makes them much more vulnerable to toxic insults; and (ii) if
exposure to Al from only few vaccines can lead to cognitive impairment
and autoimmunity in adults, is it unreasonable to question whether the
current pediatric schedules, often containing 18 Al adjuvanted vaccines,
are safe for children? By applying Hill's criteria for establishing
causality between exposure and outcome we investigated whether exposure
to Al from vaccines could be contributing to the rise in ASD prevalence
in the Western world. Our results show that: (i) children from countries
with the highest ASD prevalence appear to have the highest exposure to
Al from vaccines; (ii) the increase in exposure to Al adjuvants
significantly correlates with the increase in ASD prevalence in the
United States observed over the last two decades (Pearson r=0.92,
p<0.0001); and (iii) a significant correlation exists between the
amounts of Al administered to preschool children and the current
prevalence of ASD in seven Western countries, particularly at 3-4 months
of age (Pearson r=0.89-0.94, p=0.0018-0.0248). The application of the
Hill's criteria to these data indicates that the correlation between Al
in vaccines and ASD may be causal. Because children represent a fraction
of the population most at risk for complications following exposure to
Al, a more rigorous evaluation of Al adjuvant safety seems warranted.
