Vaccine Ingredients

This page is dedicated to examining the various types of ingredients added to the vaccines. Each vaccine may not contain all the below ingredients, but they all contain some of these. And whether it is the preservatives, adjuvants, stabilizers, or detoxification agents, they all have documented negative side effects. For more on the specifics on each vaccine, click on the CDC's "Vaccine Ingredients Sorted by Vaccine"  PDF provided on their site.

Various Ingredients Found in Vaccines

(page navigation)


"Preservatives may be defined as compounds that kill or prevent the growth of microorganisms, particularly bacteria and fungi. They are used in vaccines to prevent microbial growth in the event that the vaccine is accidentally contaminated, as might occur with repeated puncture of multi-dose vials." - FDA, 2014

Thimerosal is 49.55% Mercury

“Mercury is considered by WHO as one of the top ten chemicals or groups of chemicals of major public health concern.” - WHO, 2013

Exists in 3 different forms – title="Public Health and Economic Consequences of Methyl Mercury Toxicity to the Developing Brain" Environmental Health Perspectives, 2005:

  • Methyl Mercury (metallic elements)
  • Ethyl Mercury (inorganic salts)
  • Phenyl Mercury (organic compounds)

Thimerosal is ethyl mercury, which metabolizes in the human body as methyl mercury, and methyl mercury gets stored in the brain as a neurotoxin. - Neuroendocrinology Letters, 2005

“The blood–brain barrier is not fully developed until after the first year of life, and methyl mercury can cross this incomplete barrier.” (Rodier 1995) via Neuroendocrinology Letters, 2005

Mercury is a fat soluble metal, and since the brain contains 60% fat, it is a common site for mercury to store. – Dr. Russell Blaylock, 2006

The Scientific Studies on Thimerosal Damage

There are many medical studies that observed negative consequences of thimerosal and mercury on cells.

“Studies on monkeys have shown that ethyl mercury, like mercury vapor, crosses the cell membranes and is then converted intracellularly to inorganic mercury, which accumulates preferentially in the brain and kidneys” - Neuroendocrinology Letters, 2005

“Since the early 1930s, there has been evidence indicating that thimerosal poses a hazard to the health of human beings and is ineffective as an antimicrobial agent.” – PubMed - National Center for Biotechnology Information, 2014

"The culmination of the research that examines the effects of Thimerosal in humans indicates that it is a poison at minute levels with a plethora of deleterious consequences, even at the levels currently administered in vaccines." - International Journal of Clinical Chemistry, 2015

“Results indicate that thimerosal exerts some cytotoxic actions on cerebellar granule neurons dissociated from 2-week-old rats and its potency is almost similar to that of methylmercury.” - Toxicology, 2005

"There is no doubt that authorities in the CDC have initiated and participated in a cover-up of vaccine-induced damage from thimerosal to our children----and this I consider criminal." - Dr. Boyd Haley, international expert in mercury toxicity - Yahoo News, 2013

"From a cellular perspective, it would appear that the existing scientific literature supports the biological plausibility of a Hg-based (mercury) autism pathogenesis...Nevertheless, research studies identifying Hg's effects on glial cells and mitochondria that are consistent with findings in autistic patients, lend further support to the Hg-autism hypothesis." - Environmental Toxicology and Chemistry, 2011

"We have investigated the toxicology of Thimerosal in normal human astrocytes, paying particular attention to mitochondrial function and the generation of specific oxidants. We find that ethylmercury not only inhibits mitochondrial respiration leading to a drop in the steady state membrane potential, but also concurrent with these phenomena increases the formation of superoxide, hydrogen peroxide, and Fenton/Haber-Weiss generated hydroxyl radical." - Journal of Toxicology, 2012

Hearing Before the Congressional Committee on Government Reform

Here is aCongressional Testimonial on September 8, 2004 of both the FDA and CDC . In it, Congressman Dan Burton, IN (R), questions why mercury is being put in the vaccine despite the fact that there are have been no studies on thimerosal since 1929.

That only study in 1929 was by provided the pharmaceutical Eli Lilly and Company themselves, the patent holder for thimerosal. They only tested thimerosal on 22 patients with meningococcal meningitis. All those of patients died. - The American Journal of Public Health, 2005

So for 75 years we have relied on one study provided by the manufacturer in which all the patients died as testment to thimerosal's safety and efficacy. Does this sound like the type of acceptable scientific study needed for you to put a known neurotoxin into your own body or your kids?

In fact, for the Congressional records of Tuesday, May 20, 2003, Mr. Burton presents the report prepared by the staff of the Subcommittee on Human Rights and Wellness, Committee on Government Reform that under section "II. Findings and Recommendations" point 17 states, "To date, studies conducted or funded by the CDC that purportedly dispute any correlation between autism and vaccine injury have been of poor design, under-powered, and fatally flawed. The CDC's rush to support and promote such research is reflective of a philosophical conflict in looking fairly at emerging theories and clinical data related to adverse reactions from vaccinations." - MERCURY IN MEDICINE REPORT, Congressional Record Volume 149, Number 76, 2003


1 ppm = 1000 ppb = 1 μg/ml = 1000 μg/L 1 microgram (mcg) or (μg) = 0.001 μg/g (milligram) = 1000 ppb

IQ Loss Due to Mercury

It has been long held science and common knowledge that mercury impedes the brain's cognitive abilities. But, the following sources and government agencies have clearly laid out just how little can be absorbed safely by the body, and if exceeded, just how devastating the effects can be on the brain.

"Anything above 0.0001 mg/kg-day or 10 μg is neurotoxic." - EPA, 2001

20 ppb or 0.002mg/L of mercury (inorganic) is acceptable in drinking water. – EPA, 2012 Edition of the Drinking Water Standards and Health Advisories, 2012

National blood mercury prevalence data from CDC found between “316,588 – 637,233 children each year have cord blood mercury levels > 5.8 μg/L, a level associated with loss of IQ.” – Environmental Health Perspectives, 2005

“IQ losses linked to mercury range from one-fifth of an IQ point to as much as 24 points.” – CBS News, 2005

“4 percent of babies, or about 180,000, are born each year with blood mercury levels between 7.13 and 15 micrograms per liter. That level of mercury, the group concluded, causes a loss of 1.6 IQ.” – CBS News, 2005

Thimersol, Unsafe at Any Concentration

Today, your doctor and pharmacy will trumpet that the Flu Shot is 'thimerosal-free,' so as to overcome the mercury hesitation that you might have had. But, the thimerosal 'free' vaccine still has thimerosal in it, just at a reduced amount.

Here is the CDC's list of all Flu vaccines on the market and whether they contain thimerosal or not.

In an extensive interview, Frank B. Engley, Jr., PhD, who served as a trusted consultant to several government agencies including the FDA, CDC, CIA, NASA, Armed Forces Epidemiological Board (AFEB), and National Council of the NIH National Institute of Allergy and Infectious Diseases in the field of microbiology states at 23:37 in the video, "Like when the Chevrolet car, unsafe at any speed. Thimerosal, unsafe at any concentration. We have no proof that the thimerosal trace amount is ineffective. In fact, our work suggested that 3/10th's of a microgram maybe a 100 to a 1000 times more toxic than the dose we found in tissue culture. Our work with tissue culture was very early, but it has been repeated and repeated and repeated over the past ten years by investigators using much better techniques, and they are finding the thimerosal to be toxic down to parts per billions also."

Childbearing Mothers & Their Fetus

Eating Fish

13.32 μg mercury = 12oz serving (4 servings) “U.S. population consume more than 12 ounces of fish and seafood per week” - EPA via Oceana, 2005

“If the health goal is to ensure that fetal blood mercury remains below 5.8 μg/L, then the maternal blood mercury level should be below 3.5 μg/L (5.8/1.7 = 3.5).” - EPA via Oceana, 2005

“The 1999-2002 NHANES survey data show 10 percent of women have blood mercury levels above 3.5 μg/L. Therefore, the population of infants exposed prenatally to methyl mercury above the safe level is roughly twice the number of women with blood mercury above 5.8 μg/L.” - Oceana, 2005

"Currently, ethylmercury (EtHg) and adjuvant-Al (Aluminum) are the dominating interventional exposures encountered by fetuses, newborns, and infants due to immunization with Thimerosal-containing vaccines (TCVs)...Immunological and neurobehavioral effects of Thimerosal-EtHg and Al-adjuvants are not extraordinary; rather, these effects are easily detected in high and low income countries, with co-exposure to methylmercury (MeHg) or other neurotoxicants. Rigorous and replicable studies (in different animal species) have shown evidence of EtHg and Al toxicities." - International Journal of Environmental Research and Public Health, 2015

Ingesting mercury is much safer than inoculation of it; the body has a natural filtration system through the stomach that can clear out of the body much easier than injecting straight into the blood stream, bypassing the body's natural filters.

Preservative (cont'd)

Polysorbate 80

"Linked to infertility, anaphylactic shock and cancer in mice." –, 2012

Polysorbate 80 has been identified as a causative agent in anaphylactoid reaction, a life-threatening event that results from an over reactive and misdirected immune response to a substance that’s viewed as foreign. – Annals of Allergy,  Asthma and Immunology, 2005

Aborted Fetus Cells

"A cell line, according to Dr. Chris Kahlenborn, a Pittsburgh physician, “is a group of cells taken from an animal or human being and put on a petri dish. You usually have to add mitogens – chemicals that stimulate their division.” The cells divide again and agina, and the resulting cultures are kept in stock at the American Type Cultrue Collection, a nonprofit, private organization in Bethesda, Maryland, which provides them to researchers." - A Vaccine That Infects?, 1996

Yes, it's true, many of the typical recommended childhood vaccines are cultured using aborted human fetuses. If you're looking for a good religious exemption reason to opt out of vaccines, this could be it.

"Some childhood vaccines, including the one against rubella -- which is part of the MMR vaccine given to millions of children worldwide for measles, mumps and rubella -- is cultured in "WI-38 human diploid lung fibroblasts," according to the U.S. Food and Drug Administration's fact sheet on the vaccine's ingredients...Other common vaccines, including those for chicken pox, hepatitis and rabies, are also propagated in cells originating from legally aborted human fetuses, according to the FDA." - ABC News, 2015

"Varicella (chickenpox), rubella, hepatitis A, shingles and one preparation of rabies vaccine are all made by growing the viruses in fetal embryo fibroblast cells. Fibroblast cells are the cells needed to hold skin and other connective tissue together. The fetal embryo fibroblast cells used to grow vaccine viruses were first obtained from elective termination of two pregnancies in the early 1960s." - The Children's Hospital of Philadelphia, 2014

"Many of our other common vaccines, such as chicken pox, rubella and shingles, have been produced in tissue derived from fetuses, particularly two electively terminated pregnancies from the 1960s." - CNN, 2015

“Adjuvants are necessary components to warrant the efficacy of vaccines, however the overstimulation of the immune system is also associated with adverse effects.” - International Immunopharmacology, 2014

Even as of 2014, the medical experts still admit that they do not know enough about the health impact of the adjuvants in the vaccines. According to Nanomedicine (London, England), "the mechanism of action of these adjuvants often remains unclear. As more potential vaccine targets are emerging, it is becoming necessary to broaden our knowledge on the factors involved in generating potent immune responses to recombinant antigens with adjuvants."

"In recent years, four conditions: siliconosis, the Gulf war syndrome (GWS), the macrophagic myofasciitis syndrome (MMF) and post-vaccination phenomena were linked with previous exposure to an adjuvant." - Journal of Autoimmunity, 2011

"A new syndrome, namely the autoimmune/inflammatory syndrome induced by adjuvants, has recently been defined alluding to the key role of adjuvant in inducing an immune-mediated condition. Aluminum and silicone, respectively found in vaccines and breast implants, are the most commonly known adjuvants charged with development of autoimmune conditions." - Immunologic Research, 2013


A single injection in rats triggered “chronic, immune-mediated joint specific inflammation” aka rheumatoid arthritis.American Journal of Pathology, 2000


"Aluminum affects some of the membrane-like functions of the BBB (Blood Brain Barrier). It increases the rate of transmembrane diffusion and selectively changes saturable transport systems without disrupting the integrity of the membranes or altering CNS (Central Nervous System) hemodynamics. Such alterations in the access to the brain of nutrients, hormones, toxins, and drugs could be the basis of CNS dysfunction." - Neuroscience and Behavioral Reviews, 1989

"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." - Current Medicinal Chemistry, 2011

"Our results show that: (i) children from countries with the highest ASD prevalence appear to have the highest exposure to Al (Aluminum) 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)." - Journal of Inorganic Biochemistry, 2011

"In spite of a common view that aluminum (Al) salts are inert and therefore harmless as vaccine adjuvants or in immunotherapy, the reality is quite different...Autoimmune and inflammatory responses affecting the CNS (Central Nervous System) appear to underlie some forms of neurological disease, including developmental disorders." - Immunotherapy, 2014

"A new Canadian study of the mechanisms of aluminum adjuvant toxicity in pediatric patients confirms that immune challenges during early development, including those vaccine-induced, can lead to permanent detrimental alterations of the brain and immune system function.” – Lupus – Sage Journals, 2012

"Our own studies have shown a strong association between aluminum-containing vaccines and seizures as an adverse reaction [157]. Hence, aluminum, if not the primary cause, must nevertheless promote the encephalitic state associated with ASD (autism spectrum disorder)." - Entropy, page 386, 2013

"Given macrophages acting as highly mobile “Trojan horses” [107], the Khan et al. warning suggests that cumulative Al (aluminum) from repeated doses in vaccines can produce the cognitive deficits associated with long-term encephalopathies and degenerative dementias in humans." - Journal of Toxicology, page 8, 2014

Linked to Gulf War Illness - A wide range of acute and chronic symptoms have been linked to it, including fatigue, muscle pain, cognitive problems, rashes, and diarrhea. "The findings suggest a possible role for the aluminum adjuvant in some neurological features associated with GWI and possibly an additional role for the combination of adjuvants. "- NeuroMolecular Medicine, 2007

Detoxification Additive


Formaldehyde “is used to inactivate bacterial products for toxoid vaccines, (these are vaccines that use an inactive bacterial toxin to produce immunity.” - CDC, 2011

"Formaldehyde is used to detoxify diphtheria and tetanus toxins or to inactivate a virus." - American Academy of Pediatrics, 2013

"Even today, widely used vaccines, such as diphtheria, tetanus, inactivated polio, and whole cell pertussis, and even some of the newly developed acellular pertussis vaccines are produced using formaldehyde or other chemical treatments to inactivate the toxin and/or kill the microorganisms that are present in the vaccine (4, 5)." - Methods in Molecular Medicine, 1996

Formaldehyde is classified as a carcinogen. – Cancer, 2011

“In 1987, the U.S. Environmental Protection Agency (EPA) classified formaldehyde as a probable human carcinogen under conditions of unusually high or prolonged exposure” the following agree that Formaldehyde is carcinogenic - HHS’s National Toxicology Program, 2011; National Cancer Institute (NCI) since the 1980’s; The International Agency for Research on Cancer (IRAC), 2004; National Institute for Occupational Safety and Health (NIOSH)

Occupational Safety and Health Administration (OSHA) has set the exposure limit at 0.75ppm in 1992.


MSG (Monosodium Glutamate)

MSG, which can be found in potato chips, fast food, and vaccines, has been documented to lead to obesity as well as neurotoxicity in the brain. When added to a vaccine, MSG is used “to help the vaccine remain unchanged when the vaccine is exposed to heat, light, acidity, or humidity,” according to the  CDC, 2011.

Prenatal Monosodium Glutamate (MSG) treatment given through the mother's diet causes behavioral deficits in rat offspring – “Three main effects were observed in the MSG exposed offspring: (1) juvenile obesity; (2) reduced general activity levels; (3) a specific type of learning disability in discrimination learning involving choice between simultaneously present positive and negative stimuli.” - International Journal of Neuroscience, 1984

“This paper has reviewed information pertaining to an interesting group of amino acids--glutamate, aspartate, and certain of their structural analogs, some of which are neurotransmitter candidates, and all of which have both neuroexcitatory and neurotoxic activities. Evidence for the excitotoxic concept, which holds that an excitatory and possibly synapse-related mechanism underlies the neurotoxicity of these compounds, is presented." - PubMed -National Center for Biotechnology Information, 1982
