Flicking through some paperwork in an Italian
restaurant in central London, Andrew Wakefield
cuts an anonymous figure. Tall, wearing a deep
green polo shirt, chinos and outdoor jacket against
the rain, he could be an accountant checking figures.
It is unlikely that the other mid-afternoon diners
recognise a man who sparked one of the great public
health controversies.
Wakefield is a hugely divisive figure. Nine years
ago he claimed that the measles mumps rubella
vaccine, or MMR, given to every baby in the country

Forced to leave Britain to practise in America
because of the furore, Wakefield is now back.
And unrepentant. Time, and the condemnation he
faced, have deepened his suspicions about MMR.
For the last few weeks he has spent long hours
every day with his lawyers finalising evidence
he will give when he appears next week before
the General Medical Council, the body which investigates
alleged malpractice by doctors. He is facing a
long list of serious charges relating to research
he co-authored in 1998 that triggered the huge
public uncertainty about MMR that endures today.
To supporters, Wakefield is a hero, a lone crusader
for truth and a principled, caring doctor challenging
a policy that is harming significant numbers of
children. Some scientists, a handful of doctors
and parents of sons and daughters they claim have
been damaged by the triple vaccine see him as
the victim of a Department of Health-led plot
to discredit him, and the GMC hearing as a show
trial designed to suppress an uncomfortable truth.
Wakefield, talking to The Observer in his only
interview before the hearing, says he plans to
defend himself vigorously against allegations
he sees as ill-conceived and malicious. 'I've
done what I've done because my motivation is the
suffering of children I've seen and the determination
of devoted, articulate, rational parents to find
out why part of them has been destroyed, why their
child has been ruined. Why would I go through
this process of professional isolation if it was
simply to do with egomania? My alleged egomania
doesn't explain things very well. There's been
no upside for me in having pursued this issue.
It's been very difficult.
'As Vaclav Havel once said: "Follow the man
who seeks the truth; run from the man who has
found it." I can't tell you that we know
that the MMR vaccine causes autism. But the Department
of Health can tell you with 100 per cent certainty
that it doesn't, and they believe that, and that
concerns me greatly.'
The MMR controversy began on 26 February, 1998
when a group of doctors at the Royal Free Hospital
in north London, including Wakefield, held a press
conference to publicise a research paper they
had just published in the medical journal The
Lancet.
Journalists asked about the authors' main claim
to have discovered, in a study of 12 children,
a new form of inflammatory bowel disease, which
they linked to the MMR vaccine. The doctors outlined
their theory that in some children the combination
vaccine damaged the immune system because they
could not cope with simultaneously receiving a
tiny dose of three separate diseases, leaving
them susceptible to illness.
The five doctors were asked if, given the findings,
parents should continue having their children
vaccinated with the three-in-one jab. Roy Pounder,
professor of medicine at the Royal Free, passed
the question to Wakefield. The gastro-enterologist
replied that the potential link between gut disorders,
autism and MMR vaccination could no longer be
ignored. 'It's a moral issue, and I can't support
the continued use of these three vaccines given
in combination until this issue has been resolved,'
he said.
Several co-authors disagreed, as did the Department
of Health, which was furious. But, fuelled by
huge publicity, Wakefield's remarks led to large
numbers of parents then, since and today enduring
anxious hours wondering what to do: follow the
NHS advice and get their babies the MMR jab or
opt for single vaccines - argued by some to be
safer - privately instead.
MMR safety will be back in the news on 16 July
when the GMC Fitness to Practise Panel begins
disciplinary proceedings against Wakefield and
two of his Lancet co-authors, Professor John Walker-Smith
and Professor Simon Murch. The charges of serious
professional misconduct in the way they conducted
the disputed study are very grave. If upheld,
all face being struck off.
They include allegations that the three undertook
research with the 12 children without proper approval
from the Royal Free's ethics committee, failed
to conduct their study along the lines they had
sought ethical approval for, and did not treat
their young patients in accordance with the ethical
approval given. The trio are accused of carrying
out procedures on children in the study, such
as lumbar punctures and colonoscopies, that were
not in the best interests of the health of some
seriously ill young people.
According to the charge papers, the GMC will also
hear claims that Wakefield and Walker-Smith 'acted
dishonestly and irresponsibly' in failing to tell
The Lancet how they had recruited the patients,
and that the pair also acted irresponsibly when
they gave one child 'a purportedly therapeutic
substance for experimental reasons prior to obtaining
information about the safety of the substance'.
Wakefield himself is further accused of being
'dishonest and misleading' when he obtained research
funds from the Legal Aid Board, of ordering investigations
to be carried out on some children even though
he did not have the paediatric qualifications
to do so, and that he took blood from children
at a birthday party to use for research purposes
after offering them money.
Wakefield explains that legal advice and his desire
not to turn the GMC panel against him, mean he
is unable to respond directly to the allegations.
But friends say that he views the GMC hearing
as part of a long-running 'Stalinist' campaign
to ruin his reputation. He and his co-accused
deny all the claims.
Wakefield told The Observer that he has no regrets
for saying what he did in 1998 nor for continuing
to seek to prove his view of MMR as the likeliest
explanation for the rise in cases of autism in
Britain. Almost every child health expert, though,
regards the jab as hugely beneficial to public
health and rules out any connection between it
and autism.
'My concern is that it's biologically plausible
that the MMR vaccine causes or contributes to
the disease in many children, and that nothing
in the science so far dissuades me from the continued
need to pursue that question', Wakefield said.
'The trend in autism has gone up sharply in many
countries. It's interesting that that increase
coincides in many places with the introduction
of the MMR vaccine. That doesn't make it the cause.
But it's an observation that needs to be explained,
because there was clearly some environmental change
at that time that led to growing numbers of children
becoming autistic. It's a legitimate question
if MMR is one of those factors. I fear that it
may be.'
His notoriety means he is effectively an exile
in America, where he is now the executive director
of research at Thoughtful House, a non-profit-making
school and clinic in Austin, Texas, which treats
children with autism from all over the world.
'The hypothesis that we have been pursuing for
some years is that the vaccines in some way may
interact to increase the risk of the measles element
in the MMR jab damaging the intestine, and possibly
the brain directly, or alternatively that the
intestinal disease leads to secondary immune injury
to the developing brain.'
As the Havel quote suggests, Wakefield sees himself
as a dogged seeker after a disturbing truth. He
compares himself to the small band of doctors
who, soon after Aids emerged in the Eighties,
pinpointed a previously unknown virus (HIV) as
the cause, only for their theory to take years
to become established.
'In the Thatcher-Reagan era, Aids was originally
seen as something politically unacceptable, as
an act of God or a gay plague - as anything but
our problem. People were stigmatised,' he said.
'We are looking at something with autism which
is similarly politically unacceptable. That is,
how could one of medicine's modern miracles possibly
be associated with damage to children? Because
if it's shown to be linked, then it becomes less
of a miracle and more of a potential scandal.'
He believes that the Department of Health introduced
MMR into the UK in 1988 to save money and that
he has been persecuted for daring to take on powerful
political and drug industry interests.
Professor David Elliman, of Great Ormond Street
Children's Hospital in London, is one of Wakefield's
chief critics. In his view a growing public distrust
of health professionals, caused by a series of
medical scandals, has helped create a climate
in which Wakefield is seen by some as a David
taking on the Goliath of a medical establishment.
'Some people are susceptible to conspiracy theories,'
he said. 'Media coverage of the MMR row, which
gave both sides equal say, gave the public the
misleading impression that Wakefield represented
a significant body of opinion. Yet there isn't
a 50-50 split on this. It's 99.9 per cent to point
one [of a per cent].'
The science author and broadcaster Vivienne Parry,
a member of the government's independent advisory
panel, the Joint Committee on Vaccination and
Immunisation, speaks for the large majority of
scientific and medical opinion when she says:
'I think Wakefield is wrong about MMR. He has
caused great alarm and distress. But the demonisation
of him has made some people think he's being hounded
by a vengeful establishment, which has given him
a certain amount of credibility with those who
believe that all mavericks are right.'
Autism baffles science. Unlike diseases - and
autism is a neurological condition, not a disease
- few experts would claim to know exactly what
causes it, much less treat it. Some blame genetic
factors, others put the increase in those classed
as being autistic down to better diagnosis, and
others believe MMR is responsible.
Professor Simon Baron-Cohen, co-director of the
Autism Research Centre at Cambridge University,
is the UK's leading expert on the lifelong, so
far incurable, condition, which is estimated to
affect 588,000 people, about one in 100 Britons.
But even he is not precise: 'The main causes of
autism are likely to be genetic, though interacting
with some as yet unknown environmental factors.'
The National Autistic Society is similarly vague.
'The causes of autism are still being investigated.
Many experts believe that the pattern of behaviour
from which autism is diagnosed may not result
from a single cause,' it has said in a statement.
Sufferers have trouble forming relationships,
encounter difficulties in communicating in verbal
or written form, and often develop obsessional
interests.
Interestingly, the charity does not adhere to
the medical consensus which categorically rejects
any link between MMR and autism. 'The NAS is keenly
aware of the understandable concerns of parents
surrounding suggested links between autism and
the MMR vaccine,' says a spokeswoman.
Experts disagree on whether reported increases
in the number of children with autism in the UK
and elsewhere represent 'real' rises or better
diagnosis. Wakefield is now a key figure in a
growing world network of organisations, medical
professionals, treatment centres, activist groups
and campaigning parents which insists the rise
is real and that the triple jab is the reason.
Pressure is building for fresh studies of possible
links and in-depth examination of children apparently
adversely affected by vaccines. The US Court of
Federal Claims recently began hearing a case which
could lead to compensation being paid to 4,800
families who have filed lawsuits claiming that
their children ended up suffering from autism,
inflammatory bowel disease, glaucoma and epilepsy
after receiving the MMR jab and other childhood
vaccinations.
Critics point out that the US court case is not
about the MMR vaccine itself but centres on the
use of a preservative called thimerosal, which
contains 50 per cent mercury and until a few years
ago was added to routine vaccinations given to
children in the US under one. Crucially, it has
never been an element of the MMR vaccine here.
In Japan the MMR jab became mandatory in 1989,
but was withdrawn in 1993 after doctors warned
of side-effects. There were more than 2,000 claims
that it triggered reactions such as meningitis
and encephalitis, an inflammation of the brain,
and even caused deaths. Families of children who
had died received £80,000 each in damages.
'America is like the UK in that many children
are affected by autism, but over there there's
a powerful drive to get to the truth, an inherent
mistrust of the healthcare bureaucracy, and a
can-do attitude among intelligent and articulate
parents,' says Wakefield. He predicts that 'the
truth' about MMR will eventually come from America,
not the UK.
Before Wakefield's warning, 91.5 per cent of children
in England had the MMR jab by the time they turned
two. After he hit the headlines immunisation rates
fell to 87.4 per cent. Public distrust in the
vaccine was enhanced when Tony Blair refused to
say whether his son Leo had had the jab and rumours
swirled that the Blairs had travelled to France
to have the single jabs privately. The vaccination
rate subsequently fell to 79.9 per cent. The World
Health Organisation says 95 per cent is necessary
to ensure what medical experts call 'herd immunity'
- that enough children have had MMR to ensure
that they neither get the three illnesses nor
pass them on to others.
Dr Natasha Crowcroft, a childhood immunisation
expert at the Health Protection Agency, said:
'There have been outbreaks of measles in places
like nurseries. The fear is that children who
weren't vaccinated following Wakefield's comments
are now approaching secondary school age and may
well get measles, for example on holiday in Thailand
or even in Italy, where it's common.'
MMR's defenders admit that significant numbers
of parents are still apprehensive. 'Confidence
was shaken,' concedes Crowcroft. But parental
fear seems to be gradually subsiding. MMR uptake
has been increasing since 2003; by last year 84.1
per cent of two year olds in England had had it.
Gordon Brown last year said that his son, John,
two had the triple jab and made clear he saw it
as a matter of parents' responsibility to ensure
their child was covered.
Although Wakefield will be on trial at the GMC,
the hearing could prove uncomfortable for those
that make decisions about health. An editorial
in the New Scientist magazine has expressed alarm
over the implications of the GMC's action for
health professionals' freedom to raise questions
about possible safety flaws. 'The notion that
he should have kept quiet is ludicrous: there
are too many cases where doctors' concerns have
proved correct, such as their fears over the impact
of antidepressant drugs on children.'
MMR's defenders do not pretend it is always 100
per cent safe. JCVI member Vivienne Parry admits:
'There's a risk with all vaccines. It's a very
small risk. No one has ever said that the MMR
vaccine, or any vaccine, is completely without
side-effects. But as a society we have to decide
whether the benefits outweight the risks. If we
had measles, it would kill lots of children. If
you have a vaccine, it will damage some children,
but a very small number.' Parry believes the near-disappearance
of measles, mumps and rubella in recent times
means they no longer hold any horror for most
people, and that helps explain the questioning
attitude to MMR.
In the Italian restaurant, Wakefield fires a parting
shot before another meeting with his lawyers.
'I'm determined to continue to do this work, regardless
of the personal cost. It has to be done. Because
the parents of these children deserve an answer,
and their children deserve help and they can be
helped', he says. 'My colleagues and I won't be
deflected by the interests of public health policymakers
and pharmaceuticals. I want to help children with
autism; they are my motivation. If the work ultimately
exonerates the vaccines, that's fine. If not,
we need to think again.'
Nine years of controversy
February 1998 Dr Andrew Wakefield publishes research
in the Lancet proposing, for the first time, that
there may be a link between the MMR vaccine and
autism.
March 1998 A Medical Research Council panel of
experts concludes there is 'no evidence to indicate
any link' between the MMR vaccine and autism in
children.
April 1998 Finnish scientist finds after a 14-year
study that the MMR jab is not dangerous.
February 2001 Analysis published on the British
Medical Journal website concludes that the MMR
jab is not responsible for the increased rates
of autism in recent years.
February 2004 The Lancet says it should never
have published the research by Wakefield. He had
'a fatal conflict of interest' because he was
also carrying out a second, separate study into
whether parents of children allegedly damaged
by the MMR vaccine might have grounds to take
legal action.
March 2006 A 13-year-old boy who had not been
given the MMR jab becomes the first person in
Britain for 14 years to die of measles.
