Do Any Vaccines Cause Autism ?
An investigation of PRR safety signals for 100 different vaccines
by Craig Paardekooper

Introduction :The CDC (Data & Statistics on Autism Spectrum Disorder | CDC) estimates that 1 in 36 children now has autism - upfrom 1 in 110 in 2006. If this is the case, then 2.7% of children have autism . There are 2 billion children in the world ,so 2.7% equates to 54 million autistic children . 1 in 6, or 17% of children now suffer developmental disability – that’s
340 million children.

If the increase in autism is caused by certain vaccines being administered to infants then we can greatly reduce thismorbidity by identifying those harmful vaccines.
The CDC and EMA detect a safety signal when a symptom occurs with a disproportionately high incidence for a drug,
when compared to the incidence of the symptom for all drugs in the database. This is called Proportional Reporting
Ratio. Simply put PRR = rate of incidence of symptom per 100 reports for drug A
rate of incidence of symptom per 100 reports for all other drugs.

Safety Signal : PRR >= 2

Data Source :https://howbad.info/safety-signal-datasets.zip
Method :33 years of VAERS data from 1990 till 2023 were combined into a single dataset, consisting of two columns – vaccine
and symptom. There were 9,020,372 rows of data, 16,849 unique symptoms, and 99 different vaccines. The numberof records for each vaccine is shown in Appendix B.
The Proportional Reporting Ratios (PRR) were calculated for each symptom for each vaccine. Nothing like this has
been done before – where safety signal calculations have been applied to every symptom of every vaccine – enabling
rapid comparison. The PRR ratio reveals where any symptom is occurring at a rate that is disproportionately high.
The resulting spreadsheets are available as downloadable excel files, and as csv files (see above). You are strongly
advised to consult these files when investigating any vaccine.

A search was made for symptoms associated with autism. These symptoms can be divided into primary andsecondary symptoms.
Primary symptoms include 1.
2.
3.
4.

AutismAutism spectrum disorder
Broad autism phenotype
Aspergers

Secondary symptoms include –SPEECH
1. Speech disorder
2. Developmental speech disorder
3. Repetitive speech
4. Speech sound disorder
5. Lack of spontaneous speech
COGNITION
6. Cognitive disorder
7. Attention deficit hyperactivity disorder (ADH)
8. Learning disability
9. Learning disorder
10. Intellectual disability
DEVELOPMENT
11. Neurodevelopmental disorder
12. Developmental delay
13. Developmental regression
EYE CONTACT
14. Stupor
15. Staring
16. Gaze palsy
17. Decreased eye contact
SOCIAL BEHAVIOUR
18. Social avoidant behavior
19. Emotional disorder
20. Emotional poverty
HEARING
21. Impaired hearing
The aim was to see which vaccines are associated with a disproportionally high incidence of these symptoms as
measured by PRR ratio.

Results
A preliminary look at the data revealed high PRR scores for the MMR vaccine for a wide spectrum of autism related
symptoms. In addition to this, MMR has a high rank compared to the other 98 vaccines in the VAERS database acrossall the symptoms associated with autism.

Statistical SignificanceThe table below shows results for AUTISM

Autism : number of AUTISM symptoms for a vaccine
A + B : total number of symptoms for a vaccine
C : number of AUTISM symptoms for other vaccines
C + D : total number of symptoms for other vaccines
S : standard deviation for PRR score
LCI : Lower limit of the 95% confidence interval

All of the figures are provided so PRR and LCI can be manually checked.
The incidence of autism with MMR is 231 times greater than the comparator drugs. Even when we take the lower
limit of the 95% confidence interval, autism is still 200 times greater than the comparator drugs.

Above are the top 60 symptoms for MMR in the VAERS database as ordered by lower limit of the 95% confidence
interval (the number in the first column).
Out of these 60 symptoms, 18 are symptoms of autism (highlighted in yellow)
Out of these 60 symptoms, 10 are to do with infection by Mumps, Measles or Rubella, each of which is a known
cause of encephalitis, and encephalitis is a symptom of autism.
So autism isn’t just a symptom buried amongst a host of other unrelated symptoms – rather it is the common factor
relating 18 of the most commonly occurring symptoms. The only symptoms that occur with higher frequency are
infections by the very diseases that MMR is supposed to stop, and these infections are known to induce encephalitis– another symptom associated with autism !

Brain Inflammation is Linked to Autism
Encephalitis, or inflammation of the brain, may be associated with autism. Relevance of Neuroinflammation andEncephalitis in Autism - PMC (nih.gov). So is encephalitis associated with MMR vaccines?

MEA, the measles vaccine, has the highest PRR value

When ordered by LCI values we have –Its curious that MEA and MMR have the two top ranks for encephalitis.

These results are supported by the incidence of abnormal EEG (electroencephalogram)When ordered by LCI, the measles vaccine and MMR vaccine have high PRR values and high LCI values.
They are also supported by the incidence of encephalopathy

The measles vaccine has the highest PRR and LCI.
The incidence rate for MMR is high also (PRR = 4.2) and is significant at the 5% level, with a lower confidence level of
3.21.
They are also supported by the incidence of subacute sclerosing panencephalitis

They are also supported by the incidence of brain injury

The PRR score for MMR is 4.12 and the LCI is 2.54. Both of these are above 2, which means that MMR is associatedwith a high incidence of brain injury that is significant at the 5% level of probability.

Nuclear magnetic resonance imaging of the brain shows abnormal results for MEA and MMR vaccines. MMR has a
PRR value of 3.35 and a LCI of 2.44, indicating a high incidence of abnormal NMR images, which is significantly higher
than the PRR = 2 threshold.

These results show that encephalitis, or inflammation of the brain, is associated with MMR.
Inflammation associated with autism,Relevance of Neuroinflammation and Encephalitis in Autism
If this is the case, then anti-inflammatories should produce improvements for children with autism. This is confirmed
by a number of studies –Immunoregulatory and/or Anti-inflammatory Agents for the Management of Core and Associated Symptoms in
Individuals with Autism.

Possible causes of the encephalitis
Measles-induced encephalitis is the most frequent neurological complication of measles virus infection. Measlesinduced encephalitis. So is MMR associated with measles infection?

Notice that both MEA and MMR vaccines result in a higher incidence of measles compared to any other vaccine, as
shown by the very high PRR score of 155. The lower limit of the 95% confidence interval is also very high at 122.
Mumps virus can also cause encephalitis - Mumps encephalitis: return with a vengeance
Rubella virus can also cause encephalitis - Neurological aspects of rubella virus infection
So, is the MMR vaccine associated with Rubella infection ?

MMR is the only vaccine that is associated with Rubella infection , with a very high PRR (110), and that is significant
at the 5% level (LCI = 74)
So, is the MMR vaccine associated with Mumps infection ?

MMR is associated with Mumps infection, with a very high PRR (995), and that is significant at the 5% level (LCI = 74).
Also notice that the Mumps vaccine is also associated with Mumps infection, and this also is significant at the 5%
level.

Internal Consistency
I now look at the individual MMR lots associated with the symptom of “autism” and find out if the same lots areassociated with related symptoms.
Related symptoms can be –••••Cognitive
Emotional
Behavioral
Physiological

The physiological symptoms are interesting because they cast light upon the physical cause of the other symptoms –and might suggest a possible mechanism, or eliminate other mechanisms from consideration.
Internal consistency manifests when one symptom related to autism rises or falls in synchrony with another symptom
related to autism.
Here is a graph for 212 lots of MMR. The x-xis shows different MMR lots in order of decreasing autism.
•••

The blue line is the incidence of autism for those lots.
The orange line shows the incidence of anti-social behaviour
The green line shows the incidence of cognitive disorder.

Every peak of the orange line coincides with a peak of the green ! This pinpoints lots associated with an autism effect.

Note also that the MMR lots with lot codes ending in W are associated with the highest incidence of autism
symptoms.
This graph clearly shows a progressive decrease in neurodevelopmental disorder, and a progressive decrease inspeech disorder when lots are arranged in order of decreasing autism.

So there is internal consistency. Those lots that are associated with high incidence of the symptom of “autism” tend
to also have a high incidence of –Intestinal

There is, therefore considerable confirmation of the high PRR ratios for autism in both primary symptom consistency
and related secondary symptom consistency. A strong pattern of consistency is apparent across multiple symptoms.
Even though some vaccines have very strong associations with autism and its symptoms, many additional vaccines
have a lesser but still very significant effect. This would probably be cumulative with the number of these vaccines
taken at one time, and cumulative if these vaccines are taken annually. The effect of these vaccines may differ
depending upon the age at which they are administered. This may require a separate study where PRRs arecalculated for different age groups – to determine if the vaccines are more associated with devastating outcomes foryounger ages.

Conclusion
This study confirms that –a. HIGH PRR SCORES : MMR is strongly associated with autism, as evidenced by very high PRR scores,
and by a consistency in high PRR scores across multiple related symptoms.
b. STATISTICALLY SIGNIFICANT : These high PRR scores are significantly higher then the PRR = 2
threshold at a 95% confidence interval.
c. 18 of TOP 60 : An overview of the 60 most common symptoms following MMR vaccination showsthat 18 of them are related to autism.
d. INTERNAL CONSISTENCY : For individual MMR lots there is internal consistency – such that lots
associated with high incidence of autism tend also to be associated with high incidence of speechdisorder and cognitive disorder. The symptoms are in direct proportion to each other.
e. BRAIN INFLAMMATION : MMR is associated with encephalitis, and so is autism. Therapies that can
combat inflammation may help people suffering from autism
f. INFECTION : MMR is associated with infection by Rubella, Measles and Mumps, and these viruses
are known causes of encephalitis. So an antiviral treatment may help block infection and avoid thissymptom.
g. OTHER VACCINES : Other vaccines are also associated with autism, including DTAP, HPV and HEP.

I hope this study serves to convey the power of this dataset for detecting safety signals. You have seen how it can
detect elevations in the incidence of multitudes of related symptoms, enabling us to see Related Symptom
Consistency. The symptom inventory is very rich, consisting of 16849 unique symptoms, enabling a detailed andthorough investigation of any vaccine. Finally the results can be ranked and compared. You can view all the symptoms
for any one vaccine, ranked by PRR, or you can view all the vaccines for any one symptom, ranked by PRR.

This dataset is critical for informed choice. It is highly recommended that people consult this data before taking any
vaccine for themselves or for their children.

Childhood vaccine schedule
The results of PRR analysis reveal that MMR, DTAP, HEP, HIBV and PNC vaccines are all associated with a significant
risk of autism (brain damage). They generate definite safety signals.
MMR, DTAP, HEP are included on the childhood vaccine schedule. PARENTS ARE NOT BEING ADVISED OF RISK.
A doctor can get £400 for every 2 year old who is fully vaccinated with 24 vaccines (incentives paid to doctors).
However, the money is only paid out if the doctor reaches a quota of 63% of their clients. The schedule includes 4
DTAP vaccines, 3 IPV vaccines, 1 MMR vaccine, and 4 HEP vaccines. You have seen how each of these is associatedwith autism and cognitive disability.

A question arises as to why such vaccines remain on the childhood vaccine schedule despite their harmful sideeffects. The answer often given is that the benefits out weigh the risks.
But why are parents not informed of the risks so they can decide for themselves? Why do medical professionals
pretend there is no risk?
When challenged they reply that such side effects are transient and rare – but we have seen that 2.7% of all children
now suffer from autism - numbers that have tripled since 2006… so its not rare at all. And developmental disorders
have risen to a staggering 17% of children.
If a cause for neurological damage is apparent, then why is it not removed?

Risk of Autism
All children are given these vaccines, yet not all develop clinical manifestations of autism. However, even in theabsence of clinical manifestation, sub-clinical levels of autism (“asymptomatic” autism) may be present in others, andlead to a subtle cognitive deficit.
The mechanism of autism remains uncertain. However if encephalitis is a risk factor, then autism might be reducedwith the use of anti-inflammatories.
Prior to taking an MMR vaccine, parents should be informed of the following risks
•
•
•
•
•
•
•

INFECTION : the risk of measles, mumps or rubella infection associated with MMR vaccines
INFLAMMATION : the risk of encephalitis
INTESTINAL : the risk of gastrointestinal disorder, incontinence
COGNITIVE : the risk of mental retardation, attention deficit, coma
SOCIAL : the risk of speech disorder and emotional disorder
PERCEPTUAL : the risk of hearing impairment, ear disorders, eye movement disorders
MOVEMENT : Gait disturbance, epilepsy, convulsions.

Parents should also be informed that 2.7% of children now manifest a clinical level of autism, a number that hastrebled since 2006. The number of children with a sub-clinical level of autism will be greater still.

Side Effect or Main Effect and Plausible Deniability‘Vaccines such as MMR can infect the person with the very diseases they seek to avoid’. Such an assertion isevidenced by the VAERS data shown above.
Are such adverse effects a side effect of an otherwise beneficial vaccine, or are they main-effects?
•

A “side-effect” is where an adverse effect is rare, and where an intervention is designed for the welfare of
the recipient, so the side-effect is publicly acknowledged, and people are given sufficient warning of it. Suchinterventions are conceived to do more good than harm – for example, medications.

•

A “main-effect” is where an adverse effect is not rare, but instead comprises the main effect of theintervention. Such interventions may be designed for the harm of the recipient. The adverse effect is always
hidden from the public, and people are given no warning of it. Often the adverse effect is kept at a 5% levelof incidence, so it has the highest possible incidence whilst remaining just below the level of public
perception. Such interventions are conceived to do more harm than good – for example, the weaponisationof a medicine.

Autism afflicts 2.7% of children, according to the CDC, so it is not rare. And voluminous attempts have been made todeny an obvious association with MMR, as is witnessed by the myriad papers resulting from any Google search of
MMR and autism. What all of these “paid-for” papers neglect is the obvious observation that MMR frequently
induces the diseases it is meant to protect from. These diseases are KNOWN to cause encephalitis. And several peer
reviewed papers suggest that encephalitis is associated with autism. The out-right denial of any association is simply
further evidence that there is one. If they held to the truth and stated that significant risks and adverse effects are
known, then they would be more believable. Instead, they are hiding the truth, which bespeaks of hidden intentions
other than the welfare of the public.

MMR Lots Vary
Not all MMR lots appear to be equal. A cursory count of the number of adverse reports just for MMR lots in 2022
results in the following graph, where R, S, T, U and W are lot series.

These series, in turn divide into sub-series comprisedof numbers.
For example
the first and second highest for adverse reports are –T033814
T033815
The third and fourth highest for adverse reports are –T027914
T027937

A full analysis of lot numbers over the years 1990 to 2023 has commenced and will find out if the incidence autism
and its related symptoms is confined to specific lots or is common to all.
