Vaccine Ingredients

Test tubesFormaldehyde

Formaldehyde is added to vaccines as a tissue fixative, and as a preservative. Formaldehyde is oxidized in the human body to become formic acid. Formic acid is the main ingredient of bee and ant venom. Concentrated, it is corrosive and an irritant. While absorbing the oxygen of the body, it may lead to acidosis, nerve, liver and kidney damage. According to the National Research Council, between 10 – 20% of the general population may be susceptible to extreme formaldehyde toxicity, and may violently react to exposure at any level. Formaldehyde is ranked as one of the most hazardous compounds on ecosystems and human health, according to the Environmental Defense Fund. These findings are merely for environmental exposure, and therefore, the dangers are much greater with the formaldehyde included in vaccines, since it is injected directly into the blood.

The CDC admits, in regards to environmental formaldehyde exposure, that age is a critical factor: “Formaldehyde exposure is a special concern for children and the elderly. Children may become sensitive to formaldehyde more easily, which may make it more likely they will become sick.” [bold added][1]

It is important to know what impact formaldehyde can have since Formaldehyde or Formalin are excipients used in the manufacture of the following vaccines: [3]

Anthrax (BioThrax)
DTaP (all brands)
DTaP-Hep B-PPV (Pediarix)
DTaP-Hib (TriHIBit)
DT (all brands)
Td (all brands)
Hepatitis A (Havrix, Vaqta)
Hepatitis A-Hepatitis B (Twinrix)
Hib (ActHIB)
Hib-Hepatitis B (Comvax)
Influenza (Fluzone, Fluarix, FluLaval)
Japanese encephalitis (JE-Vax)
Polio-virus inactivated (Ipol)
Tdap (Adacel, Boostrix)

CDC shares information about formaldehyde in the vaccines recommended for infants and assures us that: “while chemicals are added to vaccines to inactivate a virus or bacteria and stabilize the vaccine, helping to preserve the vaccine and prevent it from losing its potency over time, the amount of chemical additives found in vaccines is very small.”[2]

Additionally, there has been a lot of discussion regarding thimerosal, a form of mercury which is a highly dangerous neurotoxin, in vaccines. The CDC assures us that “pediatric vaccines manufactured for the U.S. market are available in formulations that contain no thimerosal or only trace amounts.”[2]

I have two problems with this, firstly a trace amount of a known highly toxic neurotoxin is too much to inject into anyone. Secondly, if it’s not ok to inject babies in the USA with thimerosal, it’s not ok to inject babies in any other country with it either.

CDC is aware that formaldehyde is a dangerous environmental toxin and has a fact sheet, “What you Should Know About Formaldehyde“:

“Some people are more sensitive than others, so an exposure that causes no problems for some people can make other people sick or uncomfortable.”

“In general −

  • If you are more sensitive to formaldehyde and are exposed to more of it for a longer time, you are more likely to have symptoms.
  • If you are exposed to less formaldehyde for a shorter time, you are less likely to have symptoms, especially if you are not sensitive to formaldehyde.

“Formaldehyde is known to cause cancer. The cancer of greatest concern is cancer of the nose and throat. Scientific research has not yet shown that a certain level of formaldehyde exposure causes cancer. However, the higher the level and the longer the exposure, the greater the chance of getting cancer. Exposure to formaldehyde might increase the chance of getting cancer even at levels too low to cause symptoms.” [bold added][1]

From the CDCs Ingredients of Vaccines Fact Sheet:

“Formaldehyde is used to inactivate bacterial products for toxoid vaccines, (these are vaccines that use an inactive bacterial toxin to produce immunity.) It is also used to kill unwanted viruses and bacteria that might contaminate the vaccine during production. Most formaldehyde is removed from the vaccine before it is packaged.”[2]

I don’t know about you, but if I knew a glass had been rinsed with formaldehyde, but MOST of it had been removed, I don’t think I would be drinking out of that glass. In the same way I couldn’t inject my child with something knowing that “most” of the formaldehyde has been removed.

Additionally, the CDC admits in the Ingredients of Vaccines Fact Sheet: 1) some people should not receive vaccines; 2) parents should request the vaccine package insert and study the list of ingredients and the known adverse reactions; and 3) Health problems after vaccination should be reported. 

“What You Can Do

  • To find out what chemical additives are in specific vaccines, ask your healthcare provider or pharmacist for a copy of the vaccine package insert, which lists all ingredients in the vaccine and discusses any known adverse reactions.
  • To ensure the safety of vaccines, the Centers for Disease Control and Prevention (CDC), the Food and Drug Administration (FDA), the National Institutes of Health (NIH), and other Federal agencies routinely monitor and conduct research to examine any new evidence that would suggest possible problems with the safety of vaccines. To keep abreast of the latest information, continue to reference these materials.
  • To report a health problem that followed vaccination you or your provider should call the Vaccine Adverse Event Reporting System (VAERS) at 1-800-822-7967.” [2]

Baby funnyIt is common sense that a known extremely toxic ingredient – in ANY amount – could indeed cause serious problems. Considering the long list of health impacts that formaldehyde is known to have, and the number of vaccines which are known to contain it, and the fact that there has never been any study on what the combined impact of ALL those vaccines might be on infants, it is only sensible to say “no thanks.”

Common sense isn’t always that common – especially for those who have been confined to a laboratory or focussing on their profit & loss statements. Parents know better. Parents know how to protect their babies.

Take your time. Do the research necessary for you to make a confident decision in what is best for the health of your baby.

  10. Thanks for your feedback Rosa,
    I keep trying to warn people especially about the flu shot! It is soooooo heavily marketed. Can I use your great observation and comment? I love how you are actually seeing the reality of what is going on.

    Well done.

  11. Hi :
    I have a question> My 11 year old daughter has an appointment with her Pediatrician next month (December) and I wan to refused all the Booster vaccines the Pediatrician wants her to have. I live in the state of Vermont. What do I need to bring? Is there a letter I should sign refusing vaccination and bring it along? I know this Pediatrician is very pushy. What are my rights? Thanks!!!

    • Thanks for asking. You can find a lot of information from NVIC’s website.

      Beware that your doctor may also want to give your daughter the Guardasil vaccine, in addition to other boosters. There have been many complications, including nearly 200 deaths from this vaccine.

      You are completely in your rights to refuse all vaccines. All you need to say is “no thanks”. You are not required to give the doctor any reason. I would be polite, but firm. I have written about what to say to your doctor which you may find helpful.

      The usual time you would need an exemption letter would be for schools, in which case you can just complete a religious exemption when asked to give the school proof of vaccines. A religious exemption does not need to be from a specific religious group, it is simply in violation of your own personal religious beliefs.

      There are many parents refusing vaccines and many groups on Facebook where you can ask questions and get information that will encourage you!

    • Thank you so much for the advice. I have been reading a lot of articles about the dangers of vaccination. My husband and I have decided to refuse all these toxins vaccines into our children. Our children go to private school and there are many others parents there that do not vaccinate their children so I don’t think the school is a problem at all. But the Pediatrician mentioned something about “It is mandatory to vaccinate your children ” which I think he was trying to intimidate me. Any of us don’t even take the useless flu Vaccine. We grow our own meat and vegetables. It is all about good nutrition to have a strong immune system and vaccines will NOT do that for us vaccines will only poison our bodies. What do you think about Meningitis vaccine, that will be next. Thanks!!!!

    • Thanks Rosa,

      I have a passion for truth and am so glad my work has helped you. You are wise to investigate the best options for your children and wise to ask questions. Doctors have great information, but they don’t realize that most of their “training” regarding vaccines is directly motivated by the pharmaceutical industry and public health advocates that start with a foundation that vaccines are good and necessary to have a healthy society.

      You can find all the legal information for your state on the NVIC website There are no mandatory vaccines. Sometimes insurance companies put pressure on doctors to have a certain percentage of their patients vaccinated, so the doctor may interpret that to mean vaccines are mandatory.

      You cannot currently be forced to inject toxic substances into your body in the USA. You do not need to sign any form the doctor may have or give the doctor any exemption forms. Exemptions are used primarily when schools or other organizations ask for proof of vaccination. You simply supply your exemption letters instead.

      Regarding your question on the Meningitis vaccine, I trust in the innate immune system with which we were created to fight against all infectious diseases. I truly would rather catch and conquer an illness naturally than expose myself to known neurotoxins and foreign proteins injected into the blood stream. That would go for all vaccines including Meningitis. Of course no one would ever want to have a child catch meningitis and suffer, but I think vaccines give us false hope of safety and protection. So many children suffer with seizures, autism and other neurologic impairment, and a host of auto-immune disorders. Each parent must weigh the risks and make their own fully informed choice.

      There are simple things we can do to guard and protect our immune system without vaccines. We also need to read carefully and cautiously ALL the information available through the package inserts because it isn’t always easy to get the true science when the marketing is vigorously promoted to parents.

      I pray blessings on you and your family. May you prosper body, soul and spirit.

    • Thank you again for all your information. It is now so clear to me.
      I wanted to share this with you. I am a healthcare worker and all the patients coming to the ER (especially children) with different diagnoses such as Bronchitis, Asthma, Respiratory Infections, RSV, Pneumonia, Flu, etc. 100% of those patients have been Vaccinated. “NOT EVEN ONE” patient who has NOT been vaccinated comes to the Emergency Room. This is no brainer. If vaccines are so great for people and children why are they getting sick and filling up the ER rooms? Ha!
