Italian court vaccine autism ruling – caused by unreliable expert

On the 23 of September, 2014 a judge in the Labor Court of Milan awarded compensation (pdf, translated from Italian) to a child on the theory that the hexavalent vaccine manufactured by GSK – which protects children against polio, diphtheria, tetanus, pertussis, invasive disease Haemophilus influenzae type B and hepatitis B – caused the child’s autism. Essentially, the Italian court vaccine autism ruling seemed to state that vaccines caused autism.

The decision was based on an expert’s opinion that made several extremely problematic arguments, arguments that go against the scientific evidence. It has been criticized by the Italian scientific community (translated summary, pdf), and is, apparently, being appealed.

This post explains the reasoning of the decision, and why it is fundamentally flawed.

Italian court vaccine autism decision


Apparently, in 2006, the young boy in question was given three doses of the hexavalent vaccine. According to the decision the boy manifested symptoms immediately that culminated in a diagnosis of autism in 2010. The parents attribute the child’s autism to the vaccine, and are suing for compensation. The decision was made by a single judge in the labor court – and the scientific community’s statement highlighted that that’s part of the problem: that type of compensation proceeding was not subject to a full process of fact finding, that would have allowed more in depth discussion of the scientific issues.

The focus of the decision was on the question whether the vaccines caused the harm, and the court appointed an expert to prepare a report on this issue. The expert concluded that the vaccines more probably than not caused autism, based on three main arguments:

  • The temporal connection between the vaccine and the symptoms.
  • The vaccine ingredients, focusing on thimerosal, aluminum, and polysorbate 80.
  • Mention of five cases of autism in a report about the clinical trials from GSK.

The problem is that none of these arguments actually support a causal connection, and some are downright wrong.

Let’s start from the end.


The GSK Report


The decision said that:

[infobox icon=”quote-left”]“Actually, until GlaxoSmithKline (producer of the mentioned product, remark of the author) did not acknowledge, albeit unintentionally, the five cases of autism that have emerged during the clinical trial of lnfanrix Hexa SK, the casual connection between vaccines and disease was, like any other etiopathogenetic hypothesis, a mere possibility. This, evidently, made the succession of the two facts (administration of vaccine and the progressive autistic regression) far more easily accidental than not.”[/infobox]

In other words, the decision sees the mention of five cases of autism in the report as evidence of a causal connection. On p. 625 of the report (pdf), the decision does mention such cases – but seeing that mention as evidence of causation is a misreading (or misrepresentation) of GSK’s report.

The part of the report in which this was mentioned is Appendix 4E, titled “Cumulative tabulation of all unlisted events from serious unlisted spontaneous reports and all serious unlisted reactions from clinical trial cases reported since launch,” and starts on page 592. In other words, it’s anything reported. Whether caused by the vaccine or not. A quick glance at the other reported reactions will demonstrate the problem of using these reports to show causation.

The report mentions, for example, pertussis (p. 609) among the events reported: but the vaccine includes the acellular pertussis vaccine (pdf), which only has single proteins: not a living, or even dead, bacteria. In other words, it can’t cause pertussis. Similarly, the report mentions (p. 613) hepatitis B – which also only has sub-units, nothing to give the disease – and H1N1 and measles (p. 614), not covered by the vaccine, as reported events – even though there is no way the vaccine could have caused any of those. The report also mentions “forearm fracture” (p. 614) – even though vaccines don’t break bones.

As this very limited list shows, listing of something in that section of the report is not evidence that the vaccine caused it. The judge in the labor court – who is not required to be an expert in this – may not have known that. But the expert writing the report should have. By using the report in this way, the expert misled the court into a problematic decision.

Vaccine ingredients


The decision opens by saying the vaccines in question “would have contained, in a dangerous way, some heavy and polluting metals such as aluminum – whose toxicity would increase in presence of other components such as polysorbate 80 – and mercury.” It goes on to say, later, after suggesting the GSK report shows a causal connection: “batches of the vaccine containing a mercury-based disinfectant, today officially banned because of the proven neurotoxicity, present in concentrations that largely exceed the maximum levels recommended for infants weighing a few pounds.”

This claim has been referred to by science bloggers as the “toxins gambit” (for more information see here, here, here and here; go here a more detailed, referenced discussion).

As explained by others, this claim is incorrect. The three ingredients mentioned in the decision, for example, are ingredients we are exposed to from other sources – and in the tiny amount in vaccines, the evidence is that they are safe. There is also no evidence connecting any of them to autism, and for one of them – thimerosal – there is abundant evidence to the contrary.



The decision is incorrect in describing thimerosal (also called thiomersal, depending on geographical location and language) as “banned because of the proven neurotoxicity.” First, in the United States, for example, thimerosal is not banned. It has been removed from childhood vaccines as a precautionary measure. It’s still used, however, in some multi-dose influenza vaccines, to protect against contamination with bacteria. More important, however, it has never been shown harmful. And more specifically, many studies examining whether thimerosal is linked to autism, or whether it negatively affects neuropsychological outcomes, found that no, it is not.

Let me repeat: studies looked. In different countries by independent teams. Again and again. Asking whether the amounts of thimerosal in vaccines cause autism or harm neuropsychological development. The answer, again and again and again, was no.

By raising the claim that the mercury preservative thimerosal could contribute to the boy’s autism, without mentioning the abundant evidence against it, the expert misled the court. A decision based on this problematic, counter-evidence claim is unsupported, and should not be allowed to stand.

In a statement about this, the Italian Scientific Community explained (this is a quote from the summary): “the scientific community highlighted that the mercury present (in the form of ethyl mercury) in trace amounts as a disinfectant in vaccines produced until a few years ago, has never been documented as causing any neurological damage anywhere in the world. However, it has been removed from all vaccines to stop the disinformation campaigns promoted about it by groups opposed to vaccinations.”



The hexavalent vaccines contains tiny amounts of aluminum salts as adjuvants: ingredients that enhance the immune response, allowing less of the active ingredient to be used (pdf). The decision, based on the expert report, suggests that aluminum is toxic. But in the tiny amounts aluminum salts are present in vaccines, the claim that it is toxic is against the evidence.

Explains one review:

[infobox icon=”quote-left”]The safety of aluminum has been established by experience during the past 70 years, with hundreds of millions of people inoculated with aluminum- containing vaccines. Adverse reactions including erythema, subcutaneous nodules, contact hypersensi- tivity, and granulomatous inflammation have been observed rarely (pdf). In other words, there are local reactions to the adjuvants, but that’s it. A recent review article reaffirms that.[/infobox]

Polysorbate 80


Like the other ingredients, polysorbate 80 is present in tiny amounts – much below what would harm you. One science blogger explained:

[infobox icon=”quote-left”]There is information on toxicity though – the LD50 (dose at which half of the experimental animals die) is 34500 µl (microliter) per kilogram body weight – this is the equivalent of 24 teaspoons (or 36.6 grams, see below) full of pure Polysorbate 80 for a 3.5 kilogram newborn baby. A huge amount. Vaccines contain a maximum of 100µg per dose (that is threehundredandsixtyfivethousandsevenhundred [365’700] times less than the LD50 for a newborn, we ingest 1000x that (100mg) per day, since Polysorbate 80 is used as an emulsifier in many foods (for example ice cream, yumm).[/infobox]

And there is no shred of evidence connection aluminum salts in vaccines or polysorbate 80 to autism.

By using the toxins gambit, again, the expert misled the court into making an unfounded decision.

Temporal connection


The expert correctly did not base his decision just on this, and it’s clear why. As scientists point out again and again, a temporal connection alone is not evidence of causation. With certain harms happening in a child’s first two years, and with millions of children vaccinated, it’s inevitable for some things to happen – or become noticeable – right after a child is vaccinated. It’s natural for the parents in that situation to blame the vaccine, but their natural leap to that conclusion does not make it true.

This has been directly studied in at least one case in relation to Sudden Infant Death Syndrome (SIDS). SIDS rates peak between 2-4 months, and children are vaccinated in those ages. And one group of Australian researchers calculated the odds – and showed that inevitably, some children will die in the 24-48 hours after the vaccine. Of course those parents will think it’s the vaccine, and blame themselves, suffering agony, anger, guilt. But is it the vaccine? Studies examined the question – and found no link between vaccines and SIDS.

Vaccines don’t cause SIDS. And this decision, based on inaccurate claims and anti-vaccine gambits, does not show that they cause autism, either. The scientific community has been right to highlight that there is no link between vaccines and autism, that the hexavalent vaccine has been given safely to millions of European children, and that preventable diseases carry serious risks.

Hopefully, the Italian court vaccine autism ruling will be appealed, and will be reversed on appeal.

The court has been ill served by its expert, and the Italian people have been ill served by their labor court. It would be tragic if children are harmed because some people will be misled by this problematic decision into not vaccinating, based on a belief that vaccines cause autism – when all the evidence goes the other way.

    What I would like to be studied is if all 3 ingredients together being administered all at once is deemed safe. They have been studied one at a time, but what happens when you mix 3 toxic ingredients together? Or having these ingredients injected into your body 69 times (the current amount of doses administered to a child on the vaccine schedule). We have all heard studies shown that this amount of toxins have been shown to be safe… but never have I once saw a study showing all the ingredients at once and over time. I doubt better studies will ever exist because most are afraid to actually come up with anything negative against vaccinations. If you do you get attacked by all other members of the medical community and secondly, people are afraid if anymore negative evidence comes to light everyone will abandon the vaccination program.

    • You fail biochemistry on so many levels. Do you have some plausible (based on real science, not delusional thinking) that any three “toxic” ingredients have some magical synergistic effect? What do these µg amounts of compounds do, interact in some way that you completely fail to elucidate, because, let’s be honest, you don’t know anything about chemistry?

      And, because you also don’t know anything about mathematics, you fail to understand that these “ingredients” are in such small quantities, that you could inject yourself with them 100,000 times, and you’d still fail to reach the minimum toxic dosage. Oh, and let’s not forget you failure to understand the dose-response theory of toxicology, that it takes a minimum dose (almost a million times higher than what’s in vaccines) to induce a minimal toxic effect. Why? Because the body, not a weak pathetic physiological being that you think it is, is quite capable of clearing itself of toxins, especially in sub biological doses.

      And your asinine “Argument from Ignorance”, that is, if we never studied it, it’s probably dangerous, is the work of the uneducated.

      Go learn some real science. Please.

        wow you are douche..

    • Dorit Reiss

      The whole vaccine, with all its ingredients, is studied for safety.

    The real problem lies in the fact that “our” government, which in so many ways now controls our medical institutions, has politicised matters to such a degree that no one knows what to believe. We are now supposed to accept “gender” as the definition of how one “sees” oneself, rather than a persons’ actual gender. A few years back, a government “study” made the claim that soft drinks can cause cancer. What they didn’t make readily emphasised was the fact that one would have to consume many litres of such beverages per day to reach such a danger level. I won’t even go into the wild claims and outright lies against tobacco and so-called “secondhand smoke”, which are about as accurate as a Magic Eight Ball.

    What we need is a separation of medicine, industry, and politics. We know the drug companies routinely make billions of dollars on the market. Not long ago, two of the three gentlemen who came up with “ADHD” admitted the “disease” is fictitious, non-existent. Yet, our government and our medical syndicate continue to acknowledge “ADHD”, and the prescription drug cartels continue to make a mint by putting kids on dangerous psychotropic pills such as Ritalin. Then, when they go in and shoot up a school, the government and the media focus on guns, which makes as much sense as blaming Ford and Chevy for drunk drivers.

      How about staying on topic, before you go off on rants about teh ebils of big gubmint, phamaceutical companies and your defense of assault rifles?

      • Lynn Stivers

        So far as I’m concerned, I stayed right on topic. These things are all connected. The direction “our” government is taking is no mere accident, it’s all part of an agenda that threatens the balance and security of this nation and its’ citizens, and if you’re too blind to see it that’s your problem.

    Thanks for this excellent critique. I just used it on Google+ to debunk an anti-vaxxer argument.

    • Come on. Do something more challenging. Turn coal into diamonds with your hands, and then that could impressive. LOL.

      Thanks for doing that. I don’t watch over the stupidity on Google+ as much as I should.

  • Nate Watkins

    italy is not surprising at all to me. now USA, they shouldn’t be thinking like that at all.

  • How long has it been since Italy was touted for their science? Near 500 years, right?

    • hyperzombie

      Wasn’t it in Italy that they chucked a couple of Geologists in jail for not predicting an earthquake in a timely manner?

      • As Professor Reiss reminded me, it wasn’t the Italian scientists, but their courts. Though, I do have a question about that now: In instances like the one above, and that you mentioned, why the hell are courts allowed to overstep their bounds like this?

        • Robert H. Woodman

          Italian courts, as I understand them (which is, admittedly, not much) have more power and more autonomy than US courts.

      • Robert H. Woodman

        An Italian court sent 7 scientists to prison on charges of manslaughter for failing to predict an earthquake. It took 2 years to overturn the verdict, and there was public protest when the verdict was overturned.

    • Dorit Reiss

      Note that this was not the work of the scientific community – and in fact, they spoke up against it.

      Let’s not attack an entire country because one low-level court made a bad decision. U.S. courts aren’t infallible, either.

      • Good point, and you’re correct as usual, Professor. I apologize for my overly general comment.
