  • Manufacturer package inserts for each vaccine contain important information on ingredients, contraindications, reported adverse reactions, pre-licensure clinical studies and more.
  • The package insert for Kinrix (DTaP-IPV) lists the following ingredients: bovine extract, bovine casein, formaldehyde, glutaraldehyde, aluminum hydroxide, VERO cells, sodium chloride, polysorbate 80, neomycin and polymyxin B.
  • There is a glaring lack of basic science research and safety testing of vaccine ingredients.

Vaccine ingredients, their side effects and impact on human health have been a topic of debate and discussion for many years. While there has been a lot of publicity about the potential adverse effects of individual ingredients in vaccines, such as mercury and aluminum, it is also important to be aware of the potential synergistic effects of all the combined ingredients contained in each vaccine.

By federal law, vaccine manufacturers must publish a list of vaccine ingredient information in the package insert approved by the U.S. Food and Drug Administration (FDA) that accompanies vials of vaccine sold and provided to doctors’ offices, public health clinics, pharmacies and other places where vaccines are administered. Package inserts are available for all vaccines licensed for distribution in the United States on the FDA website.1 As an example, let’s look at the childhood vaccine Kinrix that is  manufactured by GlaxoSmithKline (GSK).

What is Kinrix?

In 2008, the FDA licensed GSK’s diphtheria and tetanus toxoids and acellular pertussis adsorbed (DTaP) vaccine combined with an inactivated poliovirus (IPV) vaccine known as Kinrix (DTaP-IPV).2 Kinrix is licensed for use in the U.S as the fifth dose of the DTaP vaccine series and the fourth dose of the IPV series in children between the ages of four to six years old whose previous DTaP vaccine doses were Infanrix (DTaP) and/or Pediarix (DTaP-Hepatitis B-IPV) for the first three doses, and Infanrix for the fourth dose.2

Both DTaP and IPV vaccines are recommended in the 2017 Centers for Disease Control and Prevention’s (CDC) childhood vaccine schedule.3

Ingredients in Kinrix

According to the vaccine insert for Kinrix, it is a non-infectious, sterile vaccine to be administered intramuscularly. Each dose includes diphtheria toxoid, tetanus toxoid, inactivated pertussis toxin, pertactin, filamentous hemagglutinin and antigen units of Type 1, Type 2 and Type 3 poliovirus.4

The insert describes how the diphtheria and tetanus toxin is produced:

The diphtheria toxin is produced by growing Corynebacterium diphtheriae in Fenton medium containing a bovine extract. Tetanus toxin is produced by growing Clostridium tetani in a modified Latham medium derived from bovine casein. The bovine materials used in these extracts are sourced from countries which the United States Department of Agriculture (USDA) has determined neither have nor are at risk of bovine spongiform encephalopathy (BSE). Both toxins are detoxified with formaldehyde, concentrated by ultrafiltration, and purified by precipitation, dialysis, and sterile filtration.”4

Some ingredients mentioned above are bovine extract, bovine casein, and formaldehyde. What exactly are these ingredients and what role do they play in the Kinrix vaccine?

In brief, bovine extract is a water-based extract of pituitary glands from cattle used as a stabilizer in the vaccine.5 Bovine casein is milk protein from cattle used as a medium nutrient.5 Formaldehyde is a known carcinogen,6 and is used as an inactivating agent.5

The insert goes on to state:

The acellular pertussis antigens (PT, FHA, and pertactin) are isolated from Bordetella pertussis culture grown in modified Stainer-Scholte liquid medium. PT and FHA are isolated from the fermentation broth; pertactin is extracted from the cells by heat treatment and flocculation. The antigens are purified in successive chromatographic and precipitation steps. PT is detoxified using glutaraldehyde and formaldehyde. FHA and pertactin are treated with formaldehyde. Diphtheria and tetanus toxoids and pertussis antigens (inactivated PT, FHA, and pertactin) are individually adsorbed onto aluminum hydroxide.4

Additional ingredients include glutaraldehyde, a disinfectant used as an inactivating agent, and aluminum hydroxide, which is a known neurotoxin used as an adjuvant to hyperstimulate inflammatory immune responses in an effort to make the vaccine effective.7

The Kinrix package insert further describes the production process:

The inactivated poliovirus component of KINRIX is an enhanced potency component. Each of the 3 strains of poliovirus is individually grown in VERO cells, a continuous line of monkey kidney cells, cultivated on microcarriers. Calf serum and lactalbumin hydrolysate are used during VERO cell culture and/or virus culture. Calf serum is sourced from countries the USDA has determined neither have nor are at risk of BSE. After clarification, each viral suspension is purified by ultrafiltration, diafiltration, and successive chromatographic steps, and inactivated with formaldehyde.4

VERO cells are a lineage of kidney epithelial cells extracted from an African green monkey in 1962 and used as a growth medium for polioviruses in the vaccine.5 8

The description of the production process ends with:

Each 0.5-mL dose contains aluminum hydroxide as adjuvant (not more than 0.6 mg aluminum by assay) and 4.5 mg of sodium chloride. Each dose also contains ≤100 mcg of residual formaldehyde and ≤100 mcg of polysorbate 80 (Tween 80). Neomycin sulfate and polymyxin B are used in the poliovirus vaccine manufacturing process and may be present in the final vaccine at ≤0.05 ng neomycin and ≤0.01 ng polymyxin B per dose.4

Sodium chloride is commonly known as salt used to adjust tonicity in the vaccine.5 Polysorbate 80 is a surfactant used as an emulsifier.5 9 Neomycin and Polymyxin B are antibiotics used as antimicrobials in the vaccine.5

As Americans, we expect and want to believe that the vaccine recommendations being made by public health officials are evidence-based and thoroughly tested for safety; however this is not the case. The Kinrix package insert barely provides any evidence of safety testing of ingredients.

Loop Holes in Safety Testing of Vaccine Ingredients

There is a glaring lack of basic science research into the toxic effects of all the ingredients present in Kinrix and other vaccines, including evidence that ingredients have been tested for (1) entry into the body through injection; (2) synergistic toxicity of combined ingredients; and (3) long-term cumulative adverse effects on health.

The argument that such ingredients are harmless simply because they are present in miniscule amounts is not adequate.  The route of entry into the body for these ingredients is never considered during safety testing. The effect of toxins on brain and immune function through ingestion and inhalation is different from injection into a muscle in terms of how it is metabolized through biological processes in the body.10 Yet arguments made to justify the use of many vaccine ingredients focus on how the body processes toxins through ingestion and inhalation rather than injection.11 

Secondly, safety testing ignores the synergistic toxicity of all the ingredients combined in the vaccine. Synergism in toxicology refers to the effects of exposure to two of more toxins at the same time that leads to harmful health effects much more severe than the sum of individual ingredients given separately. Since children are usually given more than one vaccine at a time, safety testing of individual ingredients separately is hardly adequate to label a vaccine as safe.12 

Lastly, the long-term cumulative effects of the vaccine given in combination with other vaccines in the CDC’s recommended childhood vaccine schedule is overlooked. While small concentrations of particular chemicals used in vaccines may not necessarily lead to acute short-term health effects, chronic long-term effects of repeated exposure to small amounts of various ingredients in all vaccines administered to children have not been thoroughly studied.12

Looking back at the vaccine insert, it states, KINRIX has not been evaluated for carcinogenic or mutagenic potential, or for impairment of fertility.”4 This statement alone implies that this childhood vaccine has not undergone thorough safety testing.

  1. My son had a reaction to the Kinrix vaccine, he broke out in itching welts/hives all over his body for several days. I told two pediatricians ( that he saw on two different days) that the only thing new he had was the Kinrix vaccine and both just ignored me. One thought it was a peanut allergy and got an EPI pen because she said he could go into anaphylactic shock. He was prescribed a steroid but continued to break out . He was tested by an allergist who ruled out food allergy and confirmed the reaction was from the vaccine. I’m not even sure if it was reported to Vaers. His allergist told me he would sign the medical excempt form for my son because I do not want him to get a booster shot of this poison.

  2. Wow! What an amazing detailed and educational article. Nice work. What do you figure the difference in molecular density of these final stage materials is, and how does that all settle down in the final batch before individual vile filling? This article eludes to another subject which is how the final product may have some ingredients fall to the bottom, hence the concerns about getting vaccines off the top first run, or off the bottom final run. Thank you for the laymens explanation for these items. A tough but rewarding read.

  3. My son at age 8 had a series of shots after them a month later he had an allergic reaction to peanuts I have avoided all vaccines from that time he is now going to be 13 and I am being pushed to get him his DTaP I did get him his meningitis and he had a continuous cough for a week and said it was hard to swallow I can’t help but to feel that the change of my son’s body system has to do with the immunizations. I just don’t know where I stand every time we go to the pediatrician they say he has to get his DTaP the school’s asked me several times is there anything that I can do to avoid possible severe reaction. Just to mention my son is highly allergic to legumes almost died two years ago.

  4. My daughter had a reaction to DTap Kinrix. She was crying uncontrolably, and that is stated in the moderate side effects, but what scared me was she was getting histerical. (she is 5) she was acting irrational. Saying that I was a scientist…and when I told her I was not, she got really upset. She would not let it go…kept on telling me that I was a Scientist, while crying uncontrollably. Very scary. I reported on VARS, but reading the ingredients…are basically neuro toxins. I am scared and upset.

  5. This is a serious and deadly issue that will be very difficult for us to resolve/end. We have serious problems in faith based religious systems, our government, our judicial system, etc.etc. The reason we have great difficulty addressing the outcome of evils visited on us by our government, corporations, regulatory agencies, etc. etc. ad nauseam is because we have never been taught to be critical thinkers. We are dogmatrons in that from birth on we are filled with unprovable, irrational, illogical dogmas from family, community, church, government, education, etc.etc. (again) ad neaseum. We suffer from cognitive dissonance whenever new information is taken in. What does not agree with our dogmas, we reject, will not research or change our minds. Thus, the evil people who run things merely triggers our dogmas based emotions to get us to believe and support their wants. Look at our tweeter president!

  6. All opinions aside, I got Tdap vaccination for work reasons. One week after got diarrhoea, this has gone on 8 weeks. Gastroenterological exams show I have lymphocytic colitis. Never had a diarrhoea problem before. I’m 62 years old.
    Tetanus has no cure, neither has lymphocytic colitis, catch22.
    Look up mike Adams, the health ranger for info on vaccines

  7. yes… mandating the use of vaccines that are used to prevent disease should be immediately stopped because of a few isolated incidents. Plus, your kid(s) could have already had a mild form that was amplified. this is the same rampant paranoia that led people to believe vaccines cause autism, you should consult a doctor before assuming facts.

    1. Another brainwashed person John, probably never had kids and you are not reading the doctors like Dr. Mercola and Dr. Klingheardt or Dr. Malcovich experts, you obviously know nothing about health. They have not tested most vaccines since the 80’s for safety and worse they are not testing for children and the cumulative effect of so many given now. S___T they want to give Guardasill to boys now and the vaccine was designed to prevent cervicle cancer. WTF, more people have died from the flue shot than the flue, as well as the harm to hundreds of girls killed and permently harmed by Guardasil Vaccine death yes from vaccines many. Of course Lame stream media like you obiosly follow don’t say anything. Be safe stay vaccine free.

      By Dr. Mercola

      Common sense would suggest that, if we are giving our children more than five dozen vaccinations from day of birth to age 18, we are over-vaccinating our children. Yet, authorities continue to insist that “more is better” when it comes to vaccines without providing adequate scientific evidence to justify that assumption.

      If you follow the CDC’s recommended vaccination schedule, your child will receive 49 doses of 14 vaccines by the time he/she is 6 years of age. And by the age of 18, the CDC recommends that children should have gotten 69 doses of 16 vaccines. This is f–king crazy (Mine)

      ingredients found in flu vaccines:
      • Aluminum compounds: a neurotoxin associated with Alzheimer’s and dementia
      • Ammonium sulfate: attributed to respiratory toxicity
      • Beta-Propiolactdone: a chemical linked to malignant lymphatic tumors in animals
      • Ethyl mercury (thimerosal): a neurotoxin that has been associated with autism, dyslexia, mental retardation and seizures
      • Formaldehyde: a known carcinogen, neurotoxin, and gene disruptor
      • Monosodium glutamate: a preservative associated with delayed learning, and behavioral and reproductive disorders
      • Oxtoxinol-9: a vaginal spermicide-???? WTF! Mine)
      • Phenol: a toxin that is disruptive to the cardiovascular, nervous, reproductive and respiratory systems
      • Polysorbate 80: a synthetic compound that may cause anaphylactic shock and is a known carcinogen in animals

      HPV Vaccine Is Associated with Serious Health Risks, Including Sudden Death- By Dr. Mercola
      Many women are not aware that the HPV vaccine Gardasil might actually increase your risk of cervical cancer. Initially, that information came straight from Merck and was presented to the FDA prior to approval. According to Merck’s own research, if you have been exposed to HPV strains 16 or 18 prior to receipt of Gardasil vaccine, you could increase your risk of precancerous lesions, or worse, by 44.6 percent.

      Other health problems associated with Gardasil vaccine include immune-based inflammatory neurodegenerative disorders, suggesting that something is causing the immune system to overreact in a detrimental way—sometimes fatally.

      • Between June 1, 2006 and December 31, 2008, there were 12,424 reported adverse events following Gardasil vaccination, including 32 deaths. The girls, who were on average 18 years old, died within two to 405 days after their last Gardasil injection
      • Between May 2009 and September 2010, 16 additional deaths after Gardasil vaccination were reported. For that timeframe, there were also 789 reports of “serious” Gardasil adverse reactions, including 213 cases of permanent disability and 25 diagnosed cases of Guillain-Barre Syndrome
      • Between September 1, 2010 and September 15, 2011, another 26 deaths were reported following HPV vaccination
      • As of May 13, 2013, VAERS had received 29,686 reports of adverse events following HPV vaccinations, including 136 reports of death as well as 922 reports of disability, and 550 life-threatening adverse events.
