What is an adjuvant?
From the CDC: “An adjuvant is an ingredient of a vaccine that helps create a stronger immune response in the patient’s body. In other words, adjuvants help vaccines work better. Some vaccines made from weakened or dead germs contain naturally occurring adjuvants and help the body produce a strong protective immune response. However, most vaccines developed today include just small components of germs, such as their proteins, rather than the entire virus or bacteria. These vaccines often must be made with adjuvants to ensure the body produces an immune response strong enough to protect the patient from the germ he or she is being vaccinated against.”
Abstract: Aluminum vaccine adjuvants: are they safe? Curr Med Chem. 2011;18(17):2630-7.
“Aluminum is an experimentally demonstrated neurotoxin and the most commonly used vaccine adjuvant. Despite almost 90 years of widespread use of aluminum adjuvants, medical science’s understanding about their mechanisms of action is still remarkably poor. There is also a concerning scarcity of data on toxicology and pharmacokinetics of these compounds. In spite of this, the notion that aluminum in vaccines is safe appears to be widely accepted. Experimental research, however, clearly shows that aluminum adjuvants have a potential to induce serious immunological disorders in humans. In particular, aluminum in adjuvant form carries a risk for autoimmunity, long-term brain inflammation and associated neurological complications and may thus have profound and widespread adverse health consequences. In our opinion, the possibility that vaccine benefits may have been overrated and the risk of potential adverse effects underestimated, has not been rigorously evaluated in the medical and scientific community.”
Aluminum exposure during pregnancy
Pregnant women are being told that they are being given vaccines to protect the baby in language that implies, if not outright states, that appropriate safety studies have been done. They have not. Pregnant women in the general population are in essence being used in ongoing clinical trials without their fully informed consent.
Over the years, data has been gathered in a haphazard fashion using voluntary registries set up by pharmaceutical companies and in adverse event reports to VAERS, both of which suffer from extreme under-reporting. VSD (Vaccine Safety Datalink) studies on the safety of vaccination during pregnancy mostly include only pregnancies with live-birth outcomes, and very few studies look at the long-term health effects on children. One such rare study on vaccination with the influenza vaccine during pregnancy (Zerbo et al) found a significant association with autism. Even the most elaborate and inappropriate application of adjustments and corrections could not make the association go away in the first trimester, so the authors simply dismissed the result as due to chance. This is not science. http://jamanetwork.com/journals/jamapediatrics/article-abstract/2617988
The impact of maternal immune activation during pregnancy, and the impact of exposure to various vaccine components, such as the placenta-crossing 250 mcg of aluminum in the Tdap, on long-term neurological development are not known, but there’s enough science indicating that extreme caution is warranted. The current push to vaccinate during every single pregnancy, as well as during every outbreak, comes without any understanding of the health effect of such frequent administration of three disease antigens (tetanus, diphtheria, pertussis) and other vaccine components. This is a small sampling of studies on one component, aluminum:

Aluminum Toxicity Studies
2014 “A sudden onset of a pseudo-neurological syndrome after HPV-16/18 AS04-adjuvated vaccine: might it be an autoimmune/inflammatory syndrome induced by adjuvants (ASIA) presenting as a somatoform disorder?”
“Being involved in the production of reactive oxygen species, aluminium may impair mitochondrial bioenergetics and may lead to the generation of oxidative stress. In this review, we have discussed the oxidative stress and mitochondrial dysfunctions occurring in Al neurotoxicity. In addition, the ameliorative measures undertaken in aluminium induced oxidative stress and mitochondrial dysfunctions have also been highlighted. “
“We previously showed that poorly biodegradable aluminum-coated particles injected into muscle are promptly phagocytosed in muscle and the draining lymph nodes, and can disseminate within phagocytic cells throughout the body and slowly accumulate in brain. This strongly suggests that long-term adjuvant biopersistence within phagocytic cells is a prerequisite for slow brain translocation and delayed neurotoxicity.”
“We demonstrate that not all aluminium adjuvants are equal neither in terms of their physical properties nor their biological reactivity and potential toxicities both at the injection site and beyond. High loading of aluminium oxyhydroxide in the cytoplasm of THP-1 cells without immediate cytotoxicity might predispose this form of aluminium adjuvant to its subsequent transport throughout the body including access to the brain.”
“Vaccine adjuvants and vaccines may induce autoimmune and inflammatory manifestations in susceptible individuals. To date most human vaccine trials utilize aluminum (Al) adjuvants as placebos despite much evidence showing that Al in vaccine-relevant exposures can be toxic to humans and animals. We sought to evaluate the effects of Al adjuvant and the HPV vaccine Gardasil versus the true placebo on behavioral and inflammatory parameters in female mice.”
“Although generally well tolerated on the short term, it has been suspected to occasionally cause delayed neurologic problems in susceptible individuals. In particular, the long-term persistence of aluminic granuloma also termed macrophagic myofasciitis is associated with chronic arthromyalgias and fatigue and cognitive dysfunction. Safety concerns largely depend on the long biopersistence time inherent to this adjuvant, which may be related to its quick withdrawal from the interstitial fluid by avid cellular uptake; and the capacity of adjuvant particles to migrate and slowly accumulate in lymphoid organs and the brain, a phenomenon documented in animal models and resulting from MCP1/CCL2-dependant translocation of adjuvant-loaded monocyte-lineage cells (Trojan horse phenomenon). These novel insights strongly suggest that serious re-evaluation of long-term aluminum adjuvant phamacokinetics and safety should be carried out.”
“The observed effects also included both an alteration in mitochondrial transmembrane potential and a decrease in oxidative phosphorylation capacity when relatively high concentrations of aluminium were added to the isolated mitochondria. These findings contribute to explain both the ability of aluminium to generate oxidative stress and its suggested potential to act as an etiological factor by promoting the progression of neurodegenerative disorders such as Parkinson’s disease.”
“Evidence of the neurotoxicity of aluminium cations (Al3+) includes: an association between chronic aluminium exposure and the development of AD; the involvement of aluminium adjuvants in the development of ASIA; and epidemiological evidence pointing to an association between the use of aluminium adjuvants and ASD.”
