The Science Museum and MMR
Posted by apgaylard on December 29, 2008
To date, my only brief foray was on the topic of making decisions in the absence of certainty; a riposte to Dr John Briffa’s apparent instance on being able to be absolutely certain that the vaccine caused no harm before it could be endorsed.
One of the sources I cited in the piece was the Science Museum’s generally excellent web pages, “The MMR Files“. Recently bloggers Dr*T , JDC325 and Martin at “The Lay Scientist” pointed out that some of the science museum’s web content is distinctly dodgy. In particular, it cites the vociferous, bizarre and downright dangerous anti-vaccination campaign group ‘JABS’.
Aside from giving JABS undeserved credibility the pages also commit the common journalistic sin of ‘balance’. Giving equal apparent weight (in terms of column inches or air-time) to protagonists is fine where the competing views both have merit. If, however, one of the views is very much weaker than the other this approach starts to give undue credibility to the weaker view. In the context of the MMR ‘debate’ this approach has given the impression that concerns which lacked any robust evidential basis were at least as valid (if not more so) than judgements backed up by good (though not perfect) scientific work.
I feel that I must point out, before I go on, that I have tremendous sympathy for those who find themselves, or a loved one, disadvantaged through ASDs (or perhaps a world that doesn’t understand people with ASDs). This includes those involved with JABS. However, as will become evident, I don’t think that anyone’s best interests are served by barking (very loudly) up the wrong tree. Particularly if this involves undermining essential – and life-saving – vaccination programmes. Neither do I think that being in pain yourself gives you the right to inflict it on others.
So, taking (considerable) inspiration from their letters of complaint, I’ve sent one in as well. [Note: I’ve disabled the JABS links as I don’t really want to poke them with a stick!]
Dear Science Museum,
I was browsing your “mmr files” pages and though they have much to commend them I have some serious concerns about the some of the content.
Given that measles infections are running at alarming levels, and have already resulted in deaths, your giving credibility to the rabid anti-vaccination campaign group “JABS” is as baffling as it is dangerous. It is also highly irresponsible to be raising the ‘single vaccine’ issue when there is not a jot of evidence that this is either safer or as effective.
Their claims, that their children have been damaged by the MMR vaccine are absolutely without foundation. Whilst I have every sympathy for sick children and their parents, choosing to blame vaccines is not merely scientifically baseless (as you should know) but dangerous.
Please review the JABS website. This group actively discourages vaccination and perpetuates myths about MMR. This puts the lives of children at risk.(See hxxp://www.jabs.org.uk/forum/topic.asp?TOPIC_ID=1186 and hxxp://www.jabs.org.uk/forum/topic.asp?TOPIC_ID=3370 for example)
Please revise the following pages on your website to reflect science, rather than the tragic misapprehension of some understandably angry and upset parents; and your own strange attempt to balance reason with irrationality:
This latter page is also questionable, taken in isolation it could be construed as hinting at a government cover-up:
“When we spoke to him, the Department of Health’s David Salisbury wasn’t keen to be drawn on single vaccines. He says MMR is protecting the population – even if 10 per cent fewer people are taking it – but is there another reason?”
It does no one any good to pretend that there is a legitimate ‘debate’ or ‘controversy’ here: there is not. If you are in any doubt on this matter then may I refer you to the excellent “Austism’s False Prophets” by Dr. Paul Offit.
Please stop giving the bizarre fringe group JABS credibility: their views have none.
Please stop adding fuel to the anti-MMR fire yourselves.
Your “mmr files” have a lot of good information in them. Please stop contaminating them with irrational anti-scientific content.
If the science museum does not stand for science and reason, then, what is its purpose?
To avoid this being nothing more than a ‘me too’ post, I’d just like to mention where the MMR saga is today, in terms of the evidence. As I’ve just read Paul Offit’s excellent book “Autism’s False Prophets” I’ll leave it to this humane doctor.
“The science is largely complete. Ten epidemiological studies have shown MMR vaccine doesn’t cause autism; six have shown thimerosal doesn’t cause autism; three have shown thimerosal doesn’t cause subtle neurological problems; a growing body of evidence now points to the genes that are linked to autism; and despite the removal of thimerosal from vaccines in 2001, the number of children with autism continues to rise.”

On page 256 he also lists “Studies exonerating MMR”. Here are the references, with links to the on-line content where available. (It’s gratifying to note how many of these studies are not hidden behind pay-walls.)

And here’s an interesting study from this year, not cited by Offit, but well worth a read:
Hornig M, Briese T, Buie T, Bauman ML, Lauwers G, et al. (2008) Lack of Association between Measles Virus Vaccine and Autism with Enteropathy: A Case-Control Study. PLoS ONE 3(9): e3140. doi:10.1371/journal.pone.0003140
As Offit says, “The science is largely complete.” As far as it’s possible to tell, MMR does not cause autism. With a topic as complex as the causation of a diverse disorder, the evidence is as compelling as could be expected.
The idea that vaccination causes autism is, as the philosopher Imre Lakatos would have it, a degenerate research programme. It is clearly past time to move on and look at more credible causes; plus what can be done to help people with ASDs and their families.
Unfortunately it seems that some individuals (see here and here, for example) and advocacy groups have become so invested in this idea that it is going to be incredibly painful for them to back away – even if they are able – from the idea that autism is the result of vaccine damage. As Offit also mentions, a whole rag-bag of medical practitioners and alternative therapists also have a strong financial interest in perpetuating this failed hypothesis.
Thanks to a scientifically illiterate (or disinterested) media, some vocal advocacy groups, bad scientists (a.k.a. Andrew Wakefield), self-interested medical practitioners and certain elements in the CAM movement it is going to be very difficult to dislodge this dangerous idea from its place in the popular imagination.
The science museum – if it really stands for science – should be standing clear of these pressures and telling it how it is; not muddying the waters with misplaced compassion and a bogus notion of ‘balance’. I hope that they make some sensible revisions.

The Science Museum’s Holly Cave let me know today that the link to JABS is to be removed from their web pages. Also some other tidying up is being done to these rather out of date pages. This good news is covered in more detail by the Thinking is Dangerous Blog.
