MMR Vaccine Link To Autism Hypothesised

[By Shaoni Bhattacharya in Pulse magazine. Not available online.
Thanks to R. Miles and others.]

Autism may be triggered by MMR vaccine in a subgroup of children
genetically predisposed to immunological problems, new unpublished
research
suggests.
The research has led to a hypothesis that mothers who fail to
develop
protective antibodies when they themselves are vaccinated with MMR may
have
an immune problem which predisposes their children to autism.
The study postulates that autism might then be triggered by an
'immune
insult' like giving MMR or another live vaccine to the child.
Alternatively, a live vaccine booster, given inadvertently to the
mother during pregnancy, could cause autism via a teratogenic effect on
the
fetus.
The hypothesis has been described as biologically plausible by a
former medical assessor to the UK Committee on Safety of Medicines and
a key
official at the US Center for Disease Control.
Dr Edward Yazbak, a retired US paediatrician, has presented
preliminary results of his study to a conference of the authoritative
American Academy of Pediatrics.
The controversial findings are due to be published later this
year.
Dr Yazbak contacted 400 members of vaccine and parent groups
using the
internet and newsletters in the UK, Australia and the US.
He asked all mothers who had received an MMR or rubella booster
after
the age of 16, because of a failure to seroconvert to an earlier dose,
to
complete a questionnaire.
His final results reveal that among women revaccinated with MMR
or any
other live vaccine just before, during or after pregnancy, 76 per cent
had
one or more child diagnosed with autism spectrum disorders.
A further 17 per cent of these women went on to have children
with
autistic tendencies, severe attention deficit hyperactivity disorder
and
significant developmental delays.
Dr Yazbak said: 'The vaccine from the mother and the immune
predisposition of the mother are predisposing factors for the child.
'Then the child has its own vaccine which is a precipitating
factor -
except where the mother is revaccinated (during or before conception)
when
the child is damaged from birth.'
He added: 'This is a very unscientific study. I'm just saying
"listen,
this is something worth pursuing".
Dr Peter Fletcher, who was principal medical officer and medical
assessor to the CSM during the 1970's, said the hypothesis was
plausible.
