Comment on study: Early exposure to the combined measles-mumps-rubella vaccine and thimerosal-containing vaccines and risk of autism spectrum disorder

23 Nov

Missed this one from earlier this year. A study that looked at both MMR uptake and thimerosal exposure from infant vaccines. Guess what? “No convincing evidence was found in this study that MMR vaccination and increasing thimerosal dose were associated with an increased risk of ASD onset”


The abstract is below.

Why do I suspect that this is not included on “vaccine information” websites like the so-called “National Vaccine Information Center”, or “Dr. Bob’s” new site? Oh, because it doesn’t scare parents about vaccines, that’s why. And they can’t even blame the CDC or drug manufacturers for putting out a biased study (well, they can, they will, because they always do).

This study was done by Japanese academics. I’m sure some connection to Big Pharma will be produced to discount the fact that this study tells us what every other actual study on MMR and thimerosal and autism has said.

Author information
This case-control study investigated the relationship between the risk of Autism Spectrum Disorder (ASD) onset, and early exposure to the combined Measles-Mumps-Rubella (MMR) vaccine and thimerosal consumption measured from vaccinations in the highly genetically homogenous Japanese population.

Vaccination histories at 1, 3, 6, 12, 18, 24, and 36 months from birth were investigated in ASD cases (189 samples), and controls (224 samples) matching age and sex in each case. Crude odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated to determine relationship between MMR vaccination and ASD. The differences in mean values of the thimerosal dosage between cases and controls were analyzed using an unpaired t-test. MMR vaccination and thimerosal dosage were also investigated using a conditional multiple-regression model.

There were no significant differences in MMR vaccination and thimerosal dosage between cases and controls at any age. Furthermore, the ORs (95% CIs) of MMR vaccination and thimerosal dosage associated with ASD in the conditional multiple regression model were, respectively, 0.875 (0.345-2.222) and 1.205 (0.862-1.683) at age 18 months, 0.724 (0.421-1.243) and 1.343 (0.997-1.808) at 24 months, and 1.040 (0.648-1.668) and 0.844 (0.632-1.128) at 36 months. Thus, there were no significant differences.

No convincing evidence was found in this study that MMR vaccination and increasing thimerosal dose were associated with an increased risk of ASD onset.

Mr. Kennedy, if you know the science, why did you claim that the MMR vaccine contains mercury?

16 Nov

Robert Kennedy (son of Robert F. Kennedy) has been focused on reducing mercury exposure for some time. His advocacy against mercury led him to focus on vaccines (infant vaccines used to contain a mercury compound as a preservative). And, the main argument against mercury in vaccines is the (now totally failed) idea that mercury in vaccines causes autism.

It’s important to keep that autism is not his priority. It’s his tool to allege dangers of vaccines. He’s not out to help us out, but instead to use us to help him.

Add to this that he’s a lawyer, not a scientist and he’s from a very political family. Three are lawyers and politicians actually understand science. Mr Kennedy claims he is in that number (he’s “rabidly pro-science”), but in reality he either doesn’t understand the science or the facts are just be a political tool for him.

That Mr. Kennedy feels the need to instill in us the message that he understands science may stem from the fact that his first attempt at discussing autism and vaccines met with disaster. He published an article “deadly immunity” (because, you know, very pro-vaccine people use terms like “deadly immunity” to discuss vaccines, right?). This article was published both in Rolling Stone and In Salon’s Correcting our record, We’ve removed an explosive 2005 report by Robert F. Kennedy Jr. about autism and vaccines. Here’s why we read:

In 2005, Salon published online an exclusive story by Robert F. Kennedy Jr. that offered an explosive premise: that the mercury-based thimerosal compound present in vaccines until 2001 was dangerous, and that he was “convinced that the link between thimerosal and the epidemic of childhood neurological disorders is real.”

The piece was co-published with Rolling Stone magazine — they fact-checked it and published it in print; we posted it online. In the days after running “Deadly Immunity,” we amended the story with five corrections (which can still be found logged here) that went far in undermining Kennedy’s exposé. At the time, we felt that correcting the piece — and keeping it on the site, in the spirit of transparency — was the best way to operate. But subsequent critics, including most recently, Seth Mnookin in his book “The Panic Virus,” further eroded any faith we had in the story’s value. We’ve grown to believe the best reader service is to delete the piece entirely.

“I regret we didn’t move on this more quickly, as evidence continued to emerge debunking the vaccines and autism link,” says former Salon editor in chief Joan Walsh, now editor at large. “But continued revelations of the flaws and even fraud tainting the science behind the connection make taking down the story the right thing to do.” The story’s original URL now links to our autism topics page, which we believe now offers a strong record of clear thinking and skeptical coverage we’re proud of — including the critical pursuit of others who continue to propagate the debunked, and dangerous, autism-vaccine link.

“…critical pursuit of others who continue to propagate the debunked, and dangerous, autism-vaccine link”. Not exactly a ringing endorsement of Mr. Kennedy’s approach nor the “science” he still promotes.

One take a moment here to discuss Mr. Kennedy’s strong record of advocating for real changes that would benefit autistics. Or we could if there were such a record. Again, we aren’t his focus. We are his tool.

So, given this long introduction, what about the claim that that the MMR vaccine contains mercury? It is in this video Mr. Kennedy produced recently. And while it may seem like a small thing, it is a clear example of misunderstanding or ignoring simple facts in order to support his argument that mercury in vaccines cause autism. Mr. Kennedy is jumping on the controversy that Brian Hooker and Andrew Wakefield tried to make last year about the MMR vaccine.

Now for those who have a basic understanding of the science, one will immediately wonder, “why is Kennedy latching on to this MMR story when there is no mercury in the MMR vaccine?” Not only does the MMR vaccine not contain mercury, it can’t contain mercury. The MMR vaccine is a live virus vaccine. Mercury is a preservative; it’s specific purpose is to kill bacteria (mostly) and viruses.

Let’s leave out the other huge warning flags here–such as the current MMR controversy Wakefield and Hooker tried to create is based on a huge amount of misrepresentations. Let’s ignore that and ask, surely Mr. Kennedy wouldn’t claim that the MMR vaccine contains mercury, right? Because that would mean either he doesn’t care about the facts or doesn’t understand the facts. It would suggest that sticking to very simple facts is taking back seat to political advocacy.

Why care, one might ask? Politicians have been ignoring facts for millennia. I care beause of the harm Mr. Kennedy brings to my community. I care because he is be scaring parents, especially African American parents, needlessly and convincing them to avoid a vaccine which prevents three very serious diseases. But more, he’s instilling in a new community the guilt and shame that comes with belief in the vaccines-cause-autism idea.

Given that long intro, here’s the video where Mr. Kennedy sends out his message to the African American community:

You can jump right to the point I’m discussing (6:45 into the video).

“…it proved that these vaccines, these mercury containing vaccines particularly, were causing autism”

When he’s talking about the William Thompson story, he’s talking about this study, Age at first measles-mumps-rubella vaccination in children with autism and school-matched control subjects: a population-based study in metropolitan atlanta. He’s talking about the MMR vaccine.

Again, the MMR doesn’t contain mercury. Never has. In fact, it can’t. And there’s no good reason why after all these years why Mr. Kennedy would not know this. In his book “Thimerosal, let the science speak”, Mr. Kennedy on two occasions (Kennedy MMR-not thimerosal 1 and Kennedy MMR-not thimerosal 1) notes that the MMR vaccine does not contain mercury.

Again, this may seem like a small thing–he got this fact wrong. So what?

There was a time when I thought that the leaders of the movements that promote the idea that vaccines cause autism were just misguided. Probably good, decent people who somehow got themselves to believe wrong ideas. It’s not that hard to believe in something false, and just because you are wrong doesn’t mean you are lying.

Well, in my opinion, that doesn’t describe Mr. Kennedy. And as I’ve noted, the consequences for my community are huge. And I don’t appreciate Mr. Kennedy what appears to be Mr. Kennedy using us as his tool.

Press Release: New Research Finds No Evidence That Thimerosal-Containing Vaccines Affect Behavior or Neuroanatomy in Infant Primates

30 Sep

Below is a press release from the Johnson Center for Child Health and Development (formerly Thoughtful House). The press release discusses a recent study which investigated the safety of vaccine schedules (present and past) using monkeys as test subjects.

The study is a follow on study to a previous series of pilot studies involving some of the same authors. The pilot studies were considered by many to be an indication of evidence that vaccines cause autism and other neurological conditions. This larger study shows no evidence of adverse effects from vaccines.

Here is the press release:

New Research Finds No Evidence That Thimerosal-Containing Vaccines Affect Behavior or Neuroanatomy in Infant Primates

(Austin, Texas) – September 28, 2015 – New research finds no evidence that thimerosal- containing vaccines cause negative behaviors or result in neuropathology in infant primates, according to a study that will be published today in the Proceedings of the National Academy of Sciences. In this study, conducted by Dr. Dwight German of the University of Texas Southwestern School of Medicine, and colleagues, infant rhesus macaques received several pediatric vaccines containing thimerosal (a mercury-based preservative) in a schedule similar to that given to infants in the 1990s. Other animals received just the measles-mumps- rubella (MMR) vaccine, which does not contain thimerosal, or an expanded vaccine schedule similar to that recommended for US infants today. Control animals received a saline injection.

Regardless of vaccination status, all animals developed normal social behaviors. Cellular analysis of three brain regions, the cerebellum, amygdala and hippocampus (all known to be altered in autism), was similar in vaccinated and unvaccinated animals.

“This comprehensive analysis of social behavior and neuropathology in 12-18 month old rhesus macaques indicated that vaccinated primates were not negatively affected by thimerosal; the same was true for animals receiving an expanded 2008 vaccine schedule, which is similar to that recommended for US infants today” explained Dr. Laura Hewitson of The Johnson Center for Child Health and Development, one of the principle investigators working on the study. Hewitson was part of a team of researchers from The Johnson Center; the University of Texas Southwestern; the Center on Human Development and Disability Infant Primate Research Laboratory; the Washington National Primate Research Center (WaNPRC) at the University of Washington, Seattle WA; and Texas A&M Health Science Center & Central Texas Veterans Health Care System.

According to Hewitson, the study was designed to compare the safety of different vaccination schedules, including the schedule from the 1990s, when thimerosal was used as a preservative in multi-dose vaccine preparations. The data from this study indicate that administration of TCVs and/or the MMR vaccine to rhesus macaques did not result in neuropathological abnormalities,or aberrant behaviors, like those often observed in autism.

Administration of thimerosal-containing vaccines to infant rhesus macaques does not result in autism-like behavior or neuropathology. Bharathi S.

Another large study shows no link between autism and the MMR vaccine (or, a comment on “Autism Occurrence by MMR Vaccine Status Among US Children With Older Siblings With and Without Autism”

22 Apr

Autism is not associated with the MMR vaccine. The MMR vaccine does not increase autism risk. To put it in plain language: the MMR vaccine does not cause autism.

Just in case the message gets lost in this discussion, I figured I’d put it plainly at the start.

A study out today compares autism rates and the use of the MMR vaccine. In specific, the researchers looked at children with an older sibling. In this way they could look at kids in a high risk group, those who had an older sibling who is autistic. The authors also looked at kids who had older siblings who are not autistic. In the end the authors found “receipt of the MMR vaccine was not associated with increased risk of ASD, regardless of whether older siblings had ASD”.

To put it simply, kids who got the MMR vaccine were not more likely to be autistic. It doesn’t matter if their older siblings were autistic or not. So, “high risk” or not, the MMR vaccine doesn’t increase autism risk.

Another way to say it, parents who skipped the MMR vaccine did nothing to prevent autism in their younger kids. Nothing. They did leave their younger kids vulnerable to measles infection.

Here’s the abstract.

Autism Occurrence by MMR Vaccine Status Among US Children With Older Siblings With and Without Autism.

Despite research showing no link between the measles-mumps-rubella (MMR) vaccine and autism spectrum disorders (ASD), beliefs that the vaccine causes autism persist, leading to lower vaccination levels. Parents who already have a child with ASD may be especially wary of vaccinations.

To report ASD occurrence by MMR vaccine status in a large sample of US children who have older siblings with and without ASD.

A retrospective cohort study using an administrative claims database associated with a large commercial health plan. Participants included children continuously enrolled in the health plan from birth to at least 5 years of age during 2001-2012 who also had an older sibling continuously enrolled for at least 6 months between 1997 and 2012.

MMR vaccine receipt (0, 1, 2 doses) between birth and 5 years of age.

ASD status defined as 2 claims with a diagnosis code in any position for autistic disorder or other specified pervasive developmental disorder (PDD) including Asperger syndrome, or unspecified PDD (International Classification of Diseases, Ninth Revision, Clinical Modification 299.0x, 299.8x, 299.9x).

Of 95 727 children with older siblings, 994 (1.04%) were diagnosed with ASD and 1929 (2.01%) had an older sibling with ASD. Of those with older siblings with ASD, 134 (6.9%) had ASD, vs 860 (0.9%) children with unaffected siblings (P < .001). MMR vaccination rates (≥1 dose) were 84% (n = 78 564) at age 2 years and 92% (n = 86 063) at age 5 years for children with unaffected older siblings, vs 73% (n = 1409) at age 2 years and 86% (n = 1660) at age 5 years for children with affected siblings. MMR vaccine receipt was not associated with an increased risk of ASD at any age. For children with older siblings with ASD, at age 2, the adjusted relative risk (RR) of ASD for 1 dose of MMR vaccine vs no vaccine was 0.76 (95% CI, 0.49-1.18; P = .22), and at age 5, the RR of ASD for 2 doses compared with no vaccine was 0.56 (95% CI, 0.31-1.01; P = .052). For children whose older siblings did not have ASD, at age 2, the adjusted RR of ASD for 1 dose was 0.91 (95% CI, 0.67-1.20; P = .50) and at age 5, the RR of ASD for 2 doses was 1.12 (95% CI, 0.78-1.59; P = .55).

In this large sample of privately insured children with older siblings, receipt of the MMR vaccine was not associated with increased risk of ASD, regardless of whether older siblings had ASD. These findings indicate no harmful association between MMR vaccine receipt and ASD even among children already at higher risk for ASD.

D.A.I.R. Foundation 2013 tax form, about $100k in revenue, $20k in program expenses

5 Mar Dr-Wakefield-Solina-and-Lee[1]

A few years back Andrew Wakefield decided to sue the BMJ and Brian Deer.  This followed a series of articles and public statements that Mr. Wakefield’s work was an “elaborate fraud” and Mr. Wakefield himself was a fraud.   Lawsuits involve attorneys and attorneys cost money, so a few efforts arose to help Mr. Wakefield pay for these costs.  I believe the first was the “Dr. Wakefield Justice Fund”.  This didn’t come across as a major effort, the twitter account made three tweets, the website appears to be down (here’s an archived version), and it doesn’t appear to have made charity status.  Another effort that came out was the Academic Integrity fund.  Again, the website seems to be down, but again there’s the archive.  In many ways it’s too bad that site didn’t continue as it because a place for Mr. Wakefield to place essays.  And his writing, while tedious, produced interesting insights into his thoughts. For example:

Obama must meet the autism tragedy head on and deal with the proximate cause of the epidemic – unsafe and untested vaccination practices.

This from a man whose supporters claim never says that vaccines cause autism.

And we can also read the approach that would later prove fatal for Alex Spourdalakis: autism must be considered a medical, especially gastrointestinal, condition and that psychiatric medications to be avoided and that are behind mass murderers.

Tragically, predictably, there will be more events like at Sandy Hook Elementary. The vast number of individuals with developmental disorders presages such events. This is not because of their diagnosis, per se, but rather I would suggest, because they may be at increased risk for adverse reactions (due to pre-existing conditions) and are being inappropriately medicated with drugs for which violence is a recognized adverse reaction. These drugs are being prescribed by a “mainstream”

Not all the fundraising efforts failed.  We also saw the rise of a group calling itself the “Defending Academic Integrity and Research” or D.A.I.R. Foundation.  D.A.I.R. states under “what we do”:

Justice is accessible only to those who can afford it. D.A.I.R. Foundation provides legal aid, coordinated public relations support, and educational materials that support the work of our sponsored applicants.

Reading their site, one applies for support and D.A.I.R. provides financial support, PR and other help.

D.A.I.R. Foundation has an open request for proposals from researchers, physicians, scientists, and academic policy drivers who have come under attack and are interested in applying for legal aid. Please Contact Us and note in the subject line “Applicant Inquiry”. Applicants follow an approval review process. Applicants who are accepted will be expected to agree to terms and conditions of the legal aid process to include partnership in strategy that assures success and can be leveraged in future cases, proceeds to D.A.I.R. Foundation following legal compensation, and development of educational and public relations materials. We also assist in reputation management

I emailed them asking for a copy of their “terms and conditions” but they did not reply.  I find it interesting that people are expected to work with D.A.I.R in developing educational an public relations materials, and apparently provide a share of the proceeds of any legal settlements they achieve.

They hold fundraisers, and it appears that Andrew Wakefield is a featured speaker at these events.  The event linked on their website was not inexpensive, but also appears to have left a large number of seats unsold. (click to enlarge)

DAIR fundraiser

Of course this leaves us wondering, how much money did D.A.I.R. bring in and how did they use it?  Well, here’s the D.A.I.R. Foundation 2013 form 990.

From this we learn that they brought in $104,488.  Of that $20,859 was spent on a grant (I assume to Andrew Wakefield).  But that is less than 1/3 of their expenses. (click to enlarge)


They spent $14,889 on salary for Dawn Loughborough (the executive director). They spent $15,256 on catering and $7,383 on travel, plus other expenses. (click to enlarge)


Or, to put it simply: they took in about $100k.  Of this about $20k went to actual program expenses, over $45k went to salary and other expenses and about $37k was left in the bank.

If you dontated, about $0.20 of each dollar went to program expenses (presumably Mr. Wakefield’s expenses) about $0.45 went to overhead and about $0.35 may be used for program expenses at a later time.

Should this grant have gone to Mr. Wakefield, I don’t see that covering a large fraction of his expenses for his failed lawsuit.  Perhaps I’m wrong, but the effort involved multiple lawyers and many, many pages of documents.

Is Andrew Wakefield’s Strategic Autism Initiative failing?

3 Mar

When Andrew Wakefield left Thoughtful House he set up a charity, the Strategic Autism Initiative.  Interestingly even now, years after it was founded, it appears to have no website or Facebook page.  What it does have is tax forms because every charity must make those public.   Last year when I looked these tax forms, a few points became apparent.  Most of the money the SAI had taken in (58%) had gone to salaries, with the lion’s share of that going to Mr. Wakefield himself.  In 2012 more money was spent on salaries that was taken in.  SAI appears to have two employees, Andrew Wakefield and Terri Arranga.  Here are the contributions to the SAI, Mr. Wakefield’s salary and Ms. Arranga’s salary for the years 2010, 2011, 2012.

SAI contributions and salaries

And here are the tax forms:

Strategic Autism Initiative 2010 tax form
Strategic Autism Initiative 2011 tax form
Strategic Autism Initiative 2012 tax form

It is worth noting that the SAI was formed towards the end of 2010, hence the low salaries for that year.

Donations were down dramatically from 2011 to 2012 leaving one to wonder: what would 2013 bring?  Did the downward trend continue? Well, here’s the 2013 tax form:

Strategic Autism Initiative 2013 tax form.

Gross receipts: $50,498, down from $113,501 for tax year 2012.  A drop of over 50%.  The SAI ran a deficit of $97,514, nearly twice what they took in.  Mr. Wakefield took no salary, Teri Arranga only $5,000.  The SAI only had $21,396 in assets at the end of the year.

In short: the SAI appears to be failing. OK, in terms of benefit to the autism communities, the SAI has continually failed.

SAI 2013 form 990

Below are the “program service accomplishments” for the SAI in 2012 and 2013.  Program services are the heart of what a charity is doing.  Well, a standard charity.  That said, ignore the money amounts listed and tell me if you can see any difference in the text.  It looks to me like they copy and pasted the accomplishments from 2012 into 2013.  If I wrote the same accomplishments one year to the next, my management would likely let me go for accomplishing nothing in a year.

SAI 2012 program services SAI 2013 program services

This tax form–the most recent one available–is from 2013.  We will have to wait for the 2014 form but if this trend continued, the SAI is either failing or has failed as an organization.

Andrew Wakefield discusses “his war with vaccines”

20 Feb

For many years Andrew Wakefield put forth the image of the reasonable scientist who has been persecuted for merely asking questions about vaccines. Over the past year, that image has been fading as Mr. Wakefield has taken a more direct approach to criticizing vaccines and those involved with vaccines. His video claiming the CDC were involved in a “Tuskegee” like experiment and were worse than Hitler, Stalin and Pol Pot was an epic departure from his previous restraint.

His latest interview, while not quite in the epic stature of the “Hitler et al.” video comments, is another example of Mr. Wakefield’s evolving rhetoric. He was interviewed by Alex Jones. Just being on the Alex Jones show is a poor choice for anyone who values accuracy over meager publicity.

The title of the video is “Dr. Unloads On Safe Vaccines”. And beneath that we can read this line:

Published on Feb 13, 2015
Alex Jones welcomes Dr. Andrew Wakefield to the studio to talk about his war with vaccines.

Here’s a screenshot of the YouTube page (click to enlarge):

alex jones on Wakefield

So, we get Mr. Wakefield’s “war on vaccines”. We of course get the obligatory, “We aren’t anti-vaccine”. OK. We also get comparisons of the vaccine program to Nazi Germany. More than once.

Mr. Wakefield seems to be saying that the MMR vaccine does not protect against measles, only the single measles vaccine does. Right. Amazing how we’ve gone so long without major outbreaks of measles with the MMR in use.

Readers may recall that last year Mr. Wakefield bungled the PR campaign for a paper by Brian Hooker. Mr. Hooker’s paper (since retracted) presented a reanalysis of an old CDC dataset on autism and claimed:

Additional research is required to better understand the relationship between MMR exposure and autism in African American males.

It was at best not a strong result in a not strong paper. But even in that paper the assertion that a causal connection was not made. But, how is this work being described now? From Mr. Wakefield on the Alex Jones show:

“And now that Dr. William Thompson, senior CDC scientist, has come forward and said that they have known for 13 years that MMR vaccine is causally associated with autism and they have hidden it from the public, from doctors from public health officials, from everybody.”

The “reanalysis” doesn’t say there’s a causal connection. Mr. Thompson’s public statement doesn’t say “causal” at all. But, hey, Alex Jones and his listeners are not the types to actually fact check Mr. Wakefield.

One could go on and on analyzing the misinformation in that interview. But statements like these make the point: Mr. Wakefield is moving away from his “reasonable guy just asking questions” mode. But we knew that when he put out his race baiting YouTube video last year.

I would be very interested in how Mr. Thompson feels about how he is represented by Mr. Wakefield. Mr. Thompson has made only the one public statement and it does not say what Mr. Wakefield claims.
