‘Vaccine Science Revisited’ authors question manufacturers’ persistence in adding Formaldehyde to childhood vaccines
Why do vaccine manufacturers persist in adding Formaldehyde (FA) or Formalin (the liquid form of formaldehyde) to vaccines when many scientists have expressed concern about injecting embalming fluid into the bodies of infants?

My co-author and I pose this question in a chapter titled Formaldehyde – The demolition crew in our book VACCINE SCIENCE REVISITED: Are Childhood Immunizations as Safe as Claimed?
In certain vaccines, formaldehyde is used to “inactivate viruses and to detoxify bacterial toxins.” However, we learned that in the making of these vaccines it’s impossible to extract all the toxins. There will always be some residual toxins left in the vaccine. When it comes to formaldehyde, this can be 0.02% FA or less.
As with other chemicals, the various forms should not be confused. We mentioned that formaldehyde becomes formalin when in liquid. To be more specific, when methyl alcohol is added to formaldehyde, it becomes formalin. A solution that’s 10% formalin, is actually 3.7-4% formaldehyde.
In researching vaccine safety generally, we struggle to understand how so many scientific studies out there can be studying the exact same thing, yet their conclusions completely contradict each other. Formaldehyde studies are no exception. If each study can be replicated by a third party in the laboratory, how can the results vary so greatly?
What’s not in dispute is that our bodies produce formaldehyde naturally. This makes it difficult to determine how safe formaldehyde in vaccines really is. Formaldehyde can damage our cells, but at the same time it can defend the cells against damage. In the latter case, our body breaks the formaldehyde down into smaller pieces. These smaller pieces are no longer formaldehyde, but are now formate. The cell uses formate to create more DNA.
Some health professionals are concerned about accumulation of formaldehyde in the body. For example, Sherri Tenpenny, Doctor of Osteopathic Medicine (DO), who has great insight into the field of natural health, argues that by the time a child is five, they have received 1.795 mg formaldehyde.
Dr. Tenpenny says, “Through sloppy and negligent math, lawmakers and manufacturers fail to throw up a red flag regarding the large amount of formaldehyde injected into young bodies with developing brains, neurological systems and organs.”
We found a study that measured accumulated formaldehyde in the brain. It showed that the more it accumulates, the less there will be “cognitive abilities during human aging”. The more severe the dementia in Alzheimer’s disease patients, the higher the formaldehyde accumulation.
The list of concerns goes on. We list some of them for our readers. All claims, links and references to scientific and medical papers, official statements and news reports are tabled at the end of each chapter.
