Naturalhealth365) In the first two years of life, babies typically receive a staggering 27 injections as part of the routine pediatric vaccination schedule. As rates of autism spectrum disorder have skyrocketed over the past few decades, many natural health experts have steadfastly asserted that these vaccines – or, more precisely, vaccine ingredients – play a role.
Now, a groundbreaking Canadian study shows that exposure to aluminum, a common vaccine additive used to enhance the immune response, is linked with autism-like behavior in young mice.
Although other studies have linked abnormal behaviors with aluminum given shortly after birth, this study is the first to examine the effects of the vaccine ingredient on specific social behaviors. This is significant, because having difficulty with social behavior is a core symptom of autism spectrum disorder.
Common vaccine ingredients are NOT so ‘harmless’
In the study, conducted by scientists from the University of British Columbia (UBC) in Vancouver and published in Journal of Inorganic Biochemistry, newborn mice were injected with aluminum hydroxide gel at dosages that correspond to what infants typically receive when following the recommended vaccination schedule.
The young mice were then given behavioral tests at 8 weeks, 17 weeks and 29 weeks.
The researchers noted that the injected mice showed decreased social interest in other mice and decreased social novelty behavior – measured by willingness to meet and interact with unfamiliar mice.
Experts say that children who go on to develop autism have a difficult time engaging in normal human interactions, and may avoid social novelty.
With rodents, as well, the corroboration exists. Mice with autism-like behavior prefer familiarity – while healthy mice prefer social novelty over familiarity.
Although the researchers cautioned that the study didn’t prove that aluminum causes increased autism risk in humans, the findings are still legitimately disturbing.
Toxic potential of aluminum varies according to the route of administration
Disturbingly, this neurotoxic metal is also found in many foods – including infant formulas. But some experts say that the harm is somewhat attenuated – as aluminum ingested orally can be excreted by the kidneys and through sweating.
According to World Mercury Project (WMP), a non-profit group dedicated to reducing exposure to all sources of mercury and other heavy metals, only about 0.25 percent of orally ingested aluminum ends up getting absorbed into blood.
This is not the case with intramuscular injection, where almost 100 percent of the aluminum is absorbed. It then circulates throughout the body and accumulates in the brain, organs and joints – where it can remain for years.
