With regards to aluminum,
First off, by adding more of a substance, it does not multiply, it just adds. So it does not have a “multiplicative” effect on the child.
The mechanism that Dooms mentions such as vomiting and diarrhea are not therapeutic for someone that ingested something with aluminum. Is there any data comparing parenteral vs enteral routes for aluminum toxicity that would validate your claim?
From CHOPs website:
Given the quantities of aluminum we are exposed to on a daily basis, the quantity of aluminum in vaccines is miniscule. Aluminum-containing vaccines have been used for decades and have been given to more than 1 billion people without problem. In spring 2000, the National Vaccine Program Office (NVPO) reviewed aluminum exposure through vaccines and determined that no changes to vaccine recommendations were needed based on aluminum content. The Global Advisory Committee on Vaccine Safety, part of the World Health Organization (WHO), has also reviewed studies and found no evidence of health risks that would require changes to vaccine policy.
