This page shall be updated regularly upon discovery of research that fits the following parameters: research relating to the connection between vaccines and autism.
Do vaccines cause autism? Is the relationship real, or is it all just a conspiracy theory? The following information is purposefully delivered with the intent of providing the public a second opinion regarding autism.
Original Ground-Breaking Discovery by Autism Librarian in January 2025:
No vaccine has ever been evaluated for it’s potential to mutate genes.
Do vaccines mutate genes to increase the susceptibility to autism or other diseases known to man?
As of February 2025, the evidence is on the package inserts themselves -typically in the Non-Clinical Toxicology section- that the vaccine was not evaluated for mutagenic or carcinogenic potential.
No vaccine that has ever been made has ever been evaluated for it’s potential to mutate genes [mutagenic potential] or increase the risk of cancers [carcinogenic potential].
The CDC cannot state ‘vaccines do not cause autism’ if they have never conducted a study to evaluate if vaccines mutate genes, and later conducted additional studies to show any genetic mutations arising out of vaccines are not associated with increased risk of autism.
The public is warned that if claims stating ‘vaccines cannot mutate genes’ are made by any individual from a health agency, they should immediately be requested for the study to scientifically support the claim.
The CDC must prove single dose vaccines as well as cumulative exposures to vaccines are not mutating genes, OR must prove that any genetic mutations rising out of single dose or cumulative vaccine exposures are not associated with increased risk of autism.
Genetic mutations by vaccines are worth considering on two fronts:
1. Parental genetic mutations from vaccines that could impact the risk of autism in the offspring.
2. Childhood genetic mutations due to prenatal and postnatal exposure to vaccines that could impact the risk of autism.
No research study should be designed that compares genetic mutations arising from one vaccine to another vaccine. This design doesn’t answer the fundamental question: is the single vaccine or multiple doses of vaccines causing ANY genetic mutations and are these related to increased risk of autism? A design comparing genetic mutations from one vaccine to another would be both a waste of time and resources, as well as fraud if there is an intentional attempt to obfuscate genetic mutations arising out of vaccines to increased risk of autism or other illnesses known to man. Given an appropriately designed study evaluating genetic mutations arising out of vaccines and determining whether these are associated to an increased risk of autism, the answer must be ‘no’ for the CDC to be exonerated from vaccines increasing the risk of autism via genetic mutations.
Vaccine manufactures’ failure to evaluate for mutagenic or carcinogenic potential of vaccines extends beyond autism.
The CDC must now prove not a single genetic mutation arising out of vaccines is associated with an increased risk of genetic susceptibility to ANY other diseases known to man on two fronts:
1. Parental genetic mutations from vaccines that could impact the risk of a disease in the offspring.
2. Childhood genetic mutations due to prenatal and postnatal exposure to vaccines that could impact their risk of a disease.
Even if health agencies attempt to continue to push upon the world the narrative that ‘vaccines save lives’:
–Can anyone state accurately and scientifically that vaccines have not increased genetic susceptibility to other diseases known to man?
–Can anyone state accurately and scientifically that vaccines have not increased risk of various types of cancers?
According to the vaccine package inserts themselves, the answer is no.
And don’t let anyone gaslight you about it.
If they try, ask them for the study to support their claim.
My discovery of this matter led to my endorsement for Robert F. Kennedy Jr. for Secretary of Health and Human Services in the USA where I provided a preliminary, independent analysis of multiple literatures on toxins associated with autism. See: A Statement for Robert F. Kennedy Jr.’s Senate Confirmation Hearing
How to Interpret the Numbers on this Page
When you browse various pages on toxins, you’ll encounter many studies. There will be a research paper title followed by numbers underneath. What do those numbers mean and why are there so many of them?
Here’s what those numbers signify:
- 1 = No Difference Between Groups: If the number is 1, it means there’s no difference in the likelihood of developing the condition (like autism) between the group exposed to a certain factor and the group that wasn’t.
- Greater than 1 = Increased Likelihood: If the number is greater than 1, it indicates that the group exposed to the factor has a higher likelihood of the condition. For example:
- 1.5: This means the exposed group has 1.5 times the odds or risk of developing autism compared to the non-exposed group. In other words, their risk is 50% higher.
- Less than 1 = Decreased Likelihood or Protective Effect: Numbers less than 1 suggest that exposure might reduce the likelihood of the condition or could even be protective. For instance:
- 0.75: This would mean the exposed group has 25% lower odds or risk compared to those not exposed.
- Multiple Numbers and Analyses:
- You’ll notice multiple numbers because researchers often look at different aspects related to autism, not just diagnosis but also symptoms or associated traits. They might also adjust for other factors (like age, gender, other health conditions) to isolate the effect of the factor they’re studying. This is why you see various analyses:
- Raw Data: Initial numbers before adjustments.
- Adjusted Analyses: Numbers after accounting for other variables to see if the factor still has an effect.
- You’ll notice multiple numbers because researchers often look at different aspects related to autism, not just diagnosis but also symptoms or associated traits. They might also adjust for other factors (like age, gender, other health conditions) to isolate the effect of the factor they’re studying. This is why you see various analyses:
Thus, when you see a number like 1.5, think of it as “the risk or odds of autism for the exposed group is 1.5 times higher compared to those not exposed.” This doesn’t mean everyone exposed will develop autism, but rather, their risk is increased by that factor.

The following studies were conducted using data from the Center for Disease Control’s Vaccine Safety Datalink (VSD).
- Verstraeten, T., Davis, R. L., Gu, D., & DeStefano, F. (2000). Increased risk of developmental neurologic impairment after high exposure to thimerosal-containing vaccine in first month of life. Proceedings of the Epidemic Intelligence Service Annual Conference, Atlanta, GA, USA. Centers for Disease Control and Prevention. Secret internal abstract.
- The following findings are comparing those exposed to highest levels of thimerosal to zero exposure.
- Autism – 7.6x increased risk
- Speech Disorders – 2.1x increased risk
- Neurodevelopmental Delays – 1.8x increased risk
- Sleep Disorders – 5x increased risk
- “This analysis suggests that high exposure to ethyl mercury from thimerosal-containing vaccines in the first month of life increases the risk of subsequent development of neurologic development impairment, but not of neurologic degenerative or renal impairment.”
- The Simpsonwood Scandal: Government officials, university experts, and industry representatives convened a secret meeting in 2000 to develop strategies to statistically dilute the relationship between thimerosal and autism. The CDC manipulated the data to a point that the strong relationship vanished, published the paper, and proclaimed to the public that it meant thimerosal did not cause autism. Verstraeten wrote a letter to “Pediatrics” stating that the study was neutral and could not rule out such a relationship.
- Robert F. Kennedy Jr. wrote an excellent article in 2005 published in Salon titled “Deadly Immunity” that received a lot of media attention at the time, but the article was later retracted for lovely censorship reasons. It was also published on the Rolling Stone website and can be viewed with a subscription.

Safety of thimerosal-containing vaccines: a two-phased study of computerized health maintenance organization databases. Pediatrics, 112(5), 1039–1048.
- The CDC’s official publication that states “In no analyses were significant increased risks found for autism or attention-deficit disorder.”
- The following findings are comparing those exposed to highest levels of thimerosal to zero exposure.
- DeStefano, F., Bhasin, T. K., Thompson, W. W., Yeargin-Allsopp, M., & Boyle, C. (2004).

- Odds of Autism with MMR Vaccine, Vaccinated Prior to 36 Months
- (All) – 1.49x Odds of Autism
- (Boys) – 1.67x Odds of Autism
- (African Americans) 2.52x Odds of Autism – Unpublished
- A vaccine scandal just as enormous and shocking as the Verstrateten cover up due to the omission of findings regarding MMR vaccination and African American children. In the official publication, CDC scientists removed all African American children from the sample who did not possess a valid State of Georgia birth certificate, and reported no difference in autism incidence in their findings, thus veiling the MMR-autism link.
- Dr. Frank DeStefano was the former director of the CDC’s Immunization Safety Office. The statistically significant findings between vaccines and autism were dismissed as artifacts of vaccine requirements for early intervention special education services. However, this assertion is contradictory to the findings themselves, because girls did not show similar results. Girls who received the MMR prior to 36 months showed an odds ratio of 1.06 compared to 2.20 compared to girls who received the MMR after 36 months of page.
- Thus, the public was unaware of this fraudulently manufactured veil between MMR and autism for about ten years, while those who continued to ask questions about the link between between vaccines and autism faced ridicule and censorship. In the meantime, many children have continued to receive MMR vaccines, and to this day, MMR remains part of the childhood vaccine schedule recommended by the CDC and which many doctor’s offices adhere to -in some cases, under penalty of releasing patients who do not abide by the schedule.
- In 2014, CDC senior scientist Dr. William Thompson via his attorney published a press release testifying to the omission of the results between MMR and African American males, which had previously been disclosed to Dr. Brian Hooker via private phone conversations. The statement has been removed from MorganVerkamp, although the link is still presently available as a footprint: “august-27-2014-press-release-statement-of-william-w-thompson-ph-d-regarding-the-2004-article-examining-the-possibility-of-a-relationship-between-mmr-vaccine-and-autism/“
- Other quotes from William Thompson related to the omission of data:
- “Oh my God, I did not believe that we did what we did, but we did. It’s all there… This is the lowest point in my career, that I went along with that paper. I have great shame now when I meet families of kids with autism, because I have been part of the problem.”
- “We’ve missed ten years of research because the CDC is so paralyzed right now by anything related to autism. They’re not doing what they should be doing because they’re afraid to look for things that might be associated.”
- To this day, the original publication has not been retracted by the journal, in spite of William Thompson’s press release.
- In 2014, Dr. Brian Hooker published “Measles-mumps-rubella vaccination timing and autism among young african american boys: a reanalysis of CDC data” in the Journal Translational Neurodegeneration. This study reanalyzed the data that had been omitted from the DeStefano 2004 publication specifically analyzing African American boys, an analysis which the DeStefano authors did not complete.
- African American Boys – 3.86x Odds of Autism, Vaccinated Prior to 36 Months
- Dr. Hooker also completed an analysis for odds of autism without mental retardation.
- All Children – 2.52x Odds of Autism without Mental Retardation, Vaccinated Prior to 36 Months
- It is worth noting that William Thompson also obtained these results but they were also omitted from the CDC’s final published study. The journal, unable to bear the weight of Dr. Hooker’s findings and their controversy, retracted his publication, which led to public criticism regarding the journal not following its own research review policies in removing the article.

- The Wakefield Connection: This particular scandal is fascinating and nefarious within the context of Dr. Andrew Wakefield’s 1998 study “Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children” which speculated a link between MMR vaccination and GI problems, resulting in a retraction of the publication and the loss of his medical license. It is interesting to note that Wakefield et al. (1998) specifically said “We did not prove an association between measles, mumps, and rubella vaccine and the syndrome described. Virological studies are underway that may help to resolve this issue.” Yet, in the spirit of vaccine-religious dogma, it resulted in a catastrophic hit to Wakefield’s career and reputation, as well as the repeated inappropriate use of this study to deny a link between vaccines and autism. Presently, it is used on the World Health Organization Website to deny the existence of a link between vaccines and autism. “Fact 4: There is no link between vaccines and autism. There is no scientific evidence to link the MMR vaccine with autism or autistic disorders. This unfortunate rumour started with a single 1998 study which was quickly found to be seriously flawed, and was retracted by the journal that published it.”
- Yet, subsequent research, such as the study published by Adams et al. (2011), which does not address vaccines, found a relationship between the severity of autism and GI problems. A multi-level analysis published this year in 2023, of which James Adams is a co-author, continues to highlight the significance of the gut in autism diagnosis.
- #WakefieldWasRight seems like a very appropriate hashtag to humor ourselves with. Albeit, the history of MMR, autism and GI problems, as well as the families, children, and adults it has affected, is a rather morbid specter to look upon.

- As a result of many with autism diagnoses also suffering from tics (e.g., Echolalia), these findings are provided here for context regarding the autism-thimerosal relationship given that restricted, repetitive behaviors are part of DSM-5 criteria for autism diagnosis:
- “Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at least two of the following, currently or by history (examples are illustrative, not exhaustive; see text): Stereotyped or repetitive motor movements, use of objects, or speech (e.g., simple motor stereotypes, lining up toys or flipping objects, echolalia, idiosyncratic phrases).”

- Thanks to Rep. Dave Weldon and Rep. Dan Burton, the CDC granted the authors of the paper access to the CDC’s private Vaccine Safety Datalink (VSD), resulting in this and additional publications.

- 2 Hepatitis B Shots – 1.34x Odds Ratio
- 1 Hepatitis B Shot – 1.34x Odds Ratio
- As a result of many with autism diagnoses also suffering from emotional disturbances, these findings are provided here for context regarding the autism-thimerosal relationship, especially given that socio-emotional reciprocity is part of DSM-5 criteria for autism diagnosis:
- “Deficits in social-emotional reciprocity, ranging, for example, from abnormal social approach and failure of normal back-and-forth conversation; to reduced sharing of interests, emotions, or affect; to failure to initiate or respond to social interactions.”

The following studies were conducted outside of the Vaccine Safety Datalink and further add to the line of evidence regarding the connection between vaccines and autism.
- Wakefield et al. (1998). Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children.
- 8 of 12 children received MMR vaccine prior to developing gastrointestinal and behavioral problems, with 5 of the children having an early adverse reaction.
- Study was retracted; with Wakefield consequently losing his medical license and reputation. Read the full story in the book “Callous Disregard,” published by Andrew Wakefield himself. Wakefield did not propose MMR caused autism, as is evident in the following quotes from the retracted study.
- “We did not prove an association between measles, mumps, and rubella vaccine and the syndrome described. Virological studies are underway that may help to resolve this issue.”
- “If there is a causal link between measles, mumps, and rubella vaccine and this syndrome, a rising incidence might be anticipated after the introduction of this vaccine in the UK in 1988. Published evidence is inadequate to show whether there is a change in incidence or a link with measles, mumps, and rubella vaccine.”

- In background studies by the CDC leading to the publication, investigators ran 6 different variations of the model. In two of the analyses, CDC found highly significant statistical results. In remaining 4 analyses, CDC only highlighted a marginally significant result and buried a highly significant result in the original study report. CDC has not completed a follow up study on these findings. Additionally, the researchers used a difference of two standard deviations of exposure (approx. 16.34 micrograms) as the threshold for analysis in spite of the fact that the standard dose of mercury from thimerosal in a single flu shot is 25 micrograms.
- Institute of Medicine
- In 2011, the Institute of Medicine (IOM), now known as the National Academy of Medicine, commissioned a committee to evaluate 158 vaccine adverse events that injury reports linked to eight different vaccines.
- Evidence for eighteen adverse “favored acceptance” of a causal relationship with administration of the vaccine, and for 5 adverse events the evidence “favored rejection” of relationship.
- The evidence was “inadequate to accept or reject” a causal relationship for 135 adverse events, including the relationship between DTaP and autism. This contradicts assertions from the CDC that vaccines do not cause autism.

- One example of fatal flaw in analysis is the authors repeatedly analyzing the data using different inclusion criteria, such as counting autism cases in children down to birth, resulting in cases much too young to have received a diagnosis.
- Another example of a fatal flaw during analysis is “overmatching,” where children in “vaccinated” and “control” groups were too closely matched to make a valid comparison (i.e., comparing “some thimerosal exposure” to a group who was only little more exposed, and calculated a risk based on this matching, instead of comparing groups of ‘No Exposure’ ‘High Exposure’).
- Mohammed et al. (2022). Does Vaccination Increase the Risk of Autism Spectrum Disorder?
- “According to our review, there is no link between the development of ASD and immunization.”
- Autism Librarian’s criticisms:
- Simply a review paper; no data analysis of any kind was conducted; thus, the statistical/mathematical foundation of the conclusion is nonexistent
- Zero studies were included in the review that used data from the CDC’s Vaccine Safety Datalink, such as the study by Mawson et al. (2017), who found a relationship between vaccination and neurodevelopmental disorders (including autism), Geier et al. (2017) who found an association between autism and mercury exposure from thimerosol containing vaccines, or other studies previously included in this review that used VSD.
- Studies conducted outside of Vaccine Safety Datalink were not included in the review in spite of being published prior to the review.
- Four of the 19 studies included in the paper are only review papers
- The study spends considerable time berating Wakefield et al. (1998) whose original findings are corroborated by additional research on gastrointestinal problems/gut microbiome and autism (Adams et al. , 2011; Li et al. 2024).

- “This study provides strong evidence against the hypothesis that MMR vaccination causes autism.”
- Goldman & Yazbak (2004) criticized the findings of the study for the following reasons:
- At the time of the study, autism was diagnosed at age 5 in Denmark, resulting in many children who had not received an autism diagnosis by the endpoint of the study.
- Mild cases of autism, such as Asperger’s, may have been undercounted
- Unusual distribution of ages in the cohorts
- Censoring rules applied to cases
- Failure to separate autism into regressive and classical cohorts
- Spitzer, W. O. (2003) criticized the findings of the study for the following reasons:
- No multidisciplinary review, original lifetime records, or double verification in the large descriptive single cohort.
- Review of the clinical records for only 40 of the 316 children with autistic disorder was inadequate
- Questionably powered study: Let us assume hypothetically that there is a vulnerability to MMR-induced disease in 10 percent of the children with autism. We can assume further that 80 percent of the overall group with autism and 95 percent of the subgroup with vulnerability have been vaccinated. In a nested, case–control design within the Danish cohorts, the odds ratio for MMR in the subgroup would be 4.17; for all the children with autism combined, the odds ratio would be 0.97, masking the association in a small subgroup. Yet, in a conservative estimate, 10 percent would represent 50,000 children in the United States, at a yearly burden of $1.25 billion.”
- Dr. Madsen’s Response: “We cannot rule out the possibility that at least one child would not have become autistic if he or she had not been vaccinated, and that point alone may be sufficient for stating causality. Unfortunately, we cannot subject this assumption to a critical test unless it is better specified. We can say that if this causal link exists, it is not frequent. We can say that MMR vaccination is not the explanation for an increasing incidence in autism, if such an increasing incidence exists. We can say that MMR vaccination is not one of the common causes of autism. But we cannot prove anything, especially not when it comes to null hypotheses.
All effect measures have a set of confidence limits that vary in width and credibility according to the size and quality of the study. We do not claim to have proven that MMR vaccination can never cause autism. We can state only that we find nothing in our data to support the hypothesis that MMR causes autism. We cannot rule out the existence of a susceptible subgroup with an increased risk of autism if vaccinated, but such a subgroup must be small.”
- SafeMinds Conclusions: “Unfortunately, their study is plagued with questionable methodological choices, unexplained data anomalies and biased adjustments. In any study that asks a fundamental question about relative proportions of exposure in affected vs. unaffected groups, accurate definitions and classifications of (a) exposure and (b) affected status are crucial to the validity of any conclusions drawn from the data. Numerous criticisms of Madsen et al. highlight a source of error in one or another of these classifications. Methodology questions aside, more straightforward approaches to the population data they report suggest an increased risk of autism in Danish children based on MMR exposure, especially when adopting a case-based approach rather than relying on person-years. A simple comparison of autism rates by birth year shows a clear increase in autism rates after the introduction of MMR in Denmark. These analyses demonstrate that frequent references made based on Madsen et al. regarding the safety of MMR are incorrect.” (pg 15)

- Children were notably missing from the study sample
- Many of the children in the sample were too young for an autism diagnosis
- Failure to eliminate those with autism related to genetic conditions from the sample
- Use of two different MMR vaccines
- Failure to control for the “dosage effect”
- Statistical method failed to capture those children with a delayed diagnosis of autism
- Vaccinated male siblings of children with autism show more autism diagnoses
- Conflict of interest of the study authors

- “There is no evidence of an association between MMR immunisation and encephalitis or encephalopathy, and autistic spectrum disorders.”
- Autism Librarian’s criticisms:

(2004), Taylor et al. (1999), Makela et al. (2002), Fombonne et al. (2001), Fombonne et al. (2006), and Honda et al. (2005); all of these studies which received substantial criticisms in the SafeMinds review.
- DeStefano (2004) data was also included in the analysis for autism, one of whose authors, CDC Scientist Dr. William Thompson, admitted to the omission of data regarding the link between MMR and African American boys.

- Under deposition, world-leading vaccinologist Dr. Kathyrn Edwards admits vaccine clinical trials are not designed to rule out that the vaccine causes autism. Additionally, she indicates she does not have evidence to indicate the vaccines do or don’t cause autism, which is inconsistent with what the CDC currently claims –that vaccines do not cause autism. [The HighWire, ref.]
- Under deposition, Dr. Stanly Plotkin M.D., who is considered the “Godfather of Vaccines,” agrees with the Institute of Medicine (IOM) review that the ‘evidence was insufficient’ to make the claim the dTAP or tDAP do or do not cause autism.

- Measles “Outbreak” In Maine Was Vaccine-Induced All Along
- “ICAN, through its attorneys, requested relevant records and received them. Incredibly, they reveal that the positive measles test was “[c]onsistent with vaccine strain,” which is apparently an “acceptable” form of measles because, as the Maine CDC announced, the strain that the child tested positive for was not considered “an infectious strain of the virus,” despite causing traditional symptoms of the disease. Decidedly absent from Maine’s announcement was the fact that the child got measles as a result of the vaccine. Maine and the CDC simply hid this fact from the public.”

Caught on Camera/Audio
- Vaccine Maker Paul Offit M.D. was recorded telling others that they cannot indicate the MMR vaccine does not cause autism. [The HighWire, ref.]
- In a CNN episode titled “Autism: Unraveling the Mystery,” Former CDC Director Julie Gerberding told CNN host Sanjay Gupta that if children have a rare mitochondrial disorder then environmental stressors may create a situation where the child’s cells cannot make enough energy to keep their brains functioning normally. She admits vaccines can occasionally cause fevers in children, and that if a child had a predisposition to mitochondrial disorder, it can “set off some damage, some of the symptoms can be symptoms that have characteristics of autism.” [ref.]
- When Sanjay Gupta asks her if we can say that “vaccines do not cause autism,” she does not immediately say ‘no.’ Instead, she says “we don’t really understand the causes of autism. We’ve got a long way to go before we get to the bottom of this.”
- She then makes reference to 15 studies by the Institute of Medicine that have found no association between vaccines and autism -however, we know from FOIA requests by Informed Consent Action Network that the CDC presently has no studies to assert their claim that vaccines do not cause autism for vaccines given in the first 6 months of life. [ICAN, ref.]
- In 2013, CDC Senior Scientist, Dr. William Thompson, was recorded in private phone conversations with Dr. Brian Hooker admitting to the omission of data in the DeStafano (2004) publication mentioned previously regarding the relationship between the MMR vaccine and African American boys. With the help of Andrew Wakefield, who had previously faced persecution for his publication on MMR vaccine and gastrointestinal issues, these private phone conversations lead to the creation of the movie Vaxxed, which can be watched for free online at The Highwire.

Vaccine Safety Project – By Children’s Health Defense
6 Steps to Vaccine Safety.
Very reasonable requests posed by Children’s Health Defense. It’s quite a wonder we aren’t meeting these standards already…but okay.
Apparently the CDC wants to give vaccines to people without meeting these 6 conditions.
What do you think of them?
- Subject vaccines to a scientifically rigorous approval process.
- Require reporting of vaccine adverse events. Automate VAERS and VSD databases for research.
- Ensure all parties involved with federal vaccine approvals and recommendations are free from conflicts of interest.
- Reevaluate all vaccines recommended by ACIP prior to the adoption of evidence-based guidelines.
- Study what makes some individuals more susceptible to vaccine injury.
- Support fully-informed consent and individual rights to refuse vaccination.
Vaccine Safety Project – 6 Steps Overview article by Children’s Health Defense
Seems quite reasonable.

Dissolving Illusions by
Suzanne Humphries MD & Roman Bystrianyk
Do vaccines really save lives?
Data from Vital Statistics indicates the morality rates of various illnesses was on a steep decline BEFORE the introduction of vaccines.
Hmph. Who would’ve thought to investigate this…


See all the graphs and read the book for yourself; an entire section is dedicated to addressing criticisms of the data.
It seems reasonable to ask the question: did vaccines really save the lives of the past they claimed to save?
If the data is showing mortality rates were already in decline…did the vaccine industry take credit for what was already occurring around the world due to other factors?
In research, these other factors are known by a little term called ‘confounds.’

Are Vaccines that Bad?
Diving into Vaccine Excipients with Open VAERS
Did you know that every single drug and vaccine on the market has an FDA package insert that includes detailed information on dosage and administration, contraindication, warnings and precautions, adverse reaction, drug interactions, and other important information?
Yep. Do the doctors who administrate the vaccine provide you the known adverse reactions before administering it?
That’s what’s called Informed Consent, in case you didn’t know.
For example, the Covid-19 AstraZeneca vaccine FDA package insert indicates “Produced in genetically modified human embryonic kidney (HEK) 293 cells.” In other words, the AstraZeneca vaccine was produced in genetically modified human tissue. By the way, the AstraZeneca vaccine has been pulled from the market, likely due to extensive lawsuits.
Similarly, the DTaP vaccine, which is given to children for the first time at the age of 2 months and again at 4 and 6 months, contains formaldehyde (a carcinogen) and aluminum hydroxide (an aluminum adjuvant) as listed on the FDA package insert. Interestingly, the post-marketing section of this package insert lists Sudden Infant Death Syndrome as an identified adverse reaction following this vaccine. Make sure to click on the FDA package insert link to verify it for yourself. Why would they add that, unless they felt it was important enough to include in the package insert?
Multiple vaccines contain aluminum adjuvants, formaldehyde, and other odd ingredients that you normally would not think of ingesting. As the joke now goes, ‘name your favorite vaccine ingredient.’
Here’s a few more examples, sourced from OpenVaers:
- MMR (MMR-II) Merck Sharp & Dohme LLC12/2020, 8/2023**: sorbitol, sucrose, hydrolyzed gelatin, recombinant human albumin, neomycin, fetal bovine serum, WI-38 human diploid lung fibroblasts used in manufacture.
- Tdap (Adacel) Sanofi Pasteur Limited 12/2020, 5/2023**: aluminum phosphate (330mcg), formaldehyde, 2-phenoxyethanol, glutaraldehyde
- Hep B (Recombivax) Merck & Co, Inc 12/2018, 4/2019**: formaldehyde,
potassium aluminum sulfate, amorphous aluminum, hydroxyphosphate sulfate (adult 500mcg, child 250mcg), yeast protein
Rather than go through every individual vaccine and list its ingredients, you are deferred to one of many investigators on these matters: Open Vaers who nicely and transparently lists known vaccine ingredients and FDA package inserts for every single vaccine on the market.

Another recommended article is by Children’s Health Defense:

FDA Package Inserts for Vaccines List Adverse Reactions
Did you know every single vaccine on the market has a corresponding FDA Package Insert that was never shown to you in the doctor’s office?
If you saw the entire list of adverse reactions for a vaccine you would probably decline it. Usually the postmarketing experience section of an FDA package insert will state the following:
“The following adverse reactions have been identified during postapproval use of [the vaccine]. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.”
The language is meant to downplay the causal relation between the vaccine the adverse reaction, thereby further protecting vaccine manufactures from liability for vaccine injury and from the ethical responsibility of conducting additional research to determine a potential causal relationship.

- “…a conservative estimate suggests that at least 69% of individuals with an ASD diagnosis have microglial activation or neuroinflammation.
- Encephalitis, which is defined as inflammation of the brain, is medical diagnosis code G04.90 in the International Classification of Disease, 10th revision; however, children with an ASD diagnosis are not generally assessed for a possible medical diagnosis of encephalitis.”
Masi, A., Glozier, N., Dale, R., & Guastella, A. J. (2017). The Immune System, Cytokines, and Biomarkers in Autism Spectrum Disorder. Neuroscience bulletin, 33(2), 194–204. https://doi.org/10.1007/s12264-017-0103-8
- “Cytokines are cell-signaling molecules that facilitate communication among cells of both the innate and adaptive immune systems. They are primary regulators of inflammation, coordinating the response to infection and associated immune challenges and are involved in a multitude of biological processes.
- As part of an integrated network, cytokines stimulate and modulate immune system activity and induce their own synthesis and the synthesis of other cytokines. They are typically soluble molecules although some remain cell-bound. Cytokines can be broadly classified into three groups based on the type of immune response: adaptive immunity, pro-inflammatory signaling, and anti-inflammatory signaling.”

Can the CDC claim ‘vaccines do not cause autism’ if vaccines are not tested for mutagenic potential to begin with?
- MMR-II Vaccine
- Nervous System. Encephalitis; encephalopathy; measles inclusion body encephalitis (MIBE) subacute sclerosing panencephalitis (SSPE); Guillain-Barré Syndrome (GBS); acute disseminated encephalomyelitis (ADEM); transverse myelitis; febrile convulsions; afebrile convulsions or seizures; ataxia; polyneuritis; polyneuropathy; ocular palsies; paresthesia; syncope.

- The vaccine virus (Oka/Merck strain) contained in ProQuad may establish latency of varicella zoster virus in immunocompetent individuals, with the potential for later development of herpes zoster.
- Cases of encephalitis or meningitis caused by vaccine strain varicella virus have been reported in immunocompromised and immunocompetent individuals previously vaccinated with VARIVAX (same varicella vaccine strain as in ProQuad) months to years after vaccination. Reported cases were commonly associated with preceding or concurrent herpes zoster rash.

- One group of rabbits was administered BioThrax twice prior to gestation and during the period of organogenesis (gestation day 7).
- A second group of rabbits was administered BioThrax twice prior to gestation and on gestation day 17. BioThrax was administered at 0.5 ml/rabbit/occasion, by intramuscular injection.
- No adverse effects on mating, fertility, pregnancy, parturition, lactation, embryo-fetal or preweaning development were observed. There were no vaccine-related fetal malformations or other evidence of teratogenesis noted in this study.
- Autism Librarian’s important note: the nonclinical toxicology study did not include a true control group that received a saline solution. Did the authors conclude ‘no adverse effects’ because of a ‘non-significant difference’ when comparing both groups exposed to the vaccine, rather than comparing a vaccine-exposed group to a non-vaccine exposed group?
- BCG (Tice)
- Immune System Reactions. Flu-Like Symptoms, Myalgia/Arthralgia, Rash, Diaphoresis.
- TICE® BCG has not been evaluated for its carcinogenic, mutagenic potentials or impairment of fertility.
- Animal reproduction studies have not been conducted with TICE® BCG. It is also not known whether TICE® BCG can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. TICE® BCG should not be given to a pregnant woman except when clearly needed. Women should be advised not to become pregnant while on therapy.
- VAXCHORA
- Nonclinical Toxicology. VAXCHORA has not been evaluated for the potential to cause carcinogenicity or genotoxicity, or to impair fertility.
- Adverse reactions. Headache, abdominal pain, nausea/vomiting, lack of appetite, and diarrhea. [although not explicitly stated on the package insert, these adverse events, although may appear minor, could speak to disruptions in gut microbiome, gut health, and neuroinflammation]
