When assessing adjuvant toxicity in children, several key points ought to be considered: (i) infants and children should not be viewed as "small adults" with regard to toxicological risk as their unique physiology makes them much more vulnerable to toxic insults; (ii) in adult humans Al vaccine adjuvants have been linked to a variety of serious autoimmune and inflammatory conditions (i.e., "ASIA"), yet children are regularly exposed to much higher amounts of Al from vaccines than adults; (iii) it is often assumed that peripheral immune responses do not affect brain function. Israeli E, Agmon-Levin N, Blank M, Shoenfeld Y. Lupus. According to the US Food and Drug Administration, safety assessments for vaccines have often not included appropriate toxicity studies because vaccines have not been viewed as inherently toxic. Unfortunately, despite its favorable safety profile, aluminum hydroxide can only weakly or moderately potentiate antigen-specific antibody responses. Background and Objective: Aluminum-containing adjuvant, such as aluminum hydroxide Al(OH) 3), has been widely used and is generally regarded as safe to use in human vaccines.It is known that particle size of adjuvant plays critical role in dictating the adsorption of antigen.

Immune challenges during early development, including those vaccine-induced, can lead to permanent detrimental alterations of the brain and immune function. J Appl Toxicol. Because this metal affects bowel activity, aluminum can cause flatulence and colic. We’ll do that below.But here’s the key point the researchers make:That’s essentially the authors’ conclusion. It is acute in respect of immediate toxicity at the vaccine injection site and it is acute in that it delivers 50 times more aluminium to the systemic circulation of an infant than is possible through daily exposure in breast milk. Aluminum "can" cause neurological harm. Biochem. Aluminum (Al) is highly neurotoxic and has been shown to impair both prenatal and postnatal brain development in humans and experimental ani- mals.1–2In addition to its neurotoxic properties, Al is a potent stimulator of the immune system, which is the very reason why it is used as an adjuvant.3–8.
