VACCINATION AGAINST deadly childhood diseases needs to be
near-universal and widely accepted, or it will cease to be truly protective.
Such wide acceptance is threatened by hearings being held on vaccine safety by
Rep. Dan Burton (R-Ind.). Mr. Burton has asserted, based on no reliable
scientific evidence, that vaccines are harming some children. He has said that
he believes his grandson, who is autistic, developed that condition as a result
of receiving a routine childhood immunization for measles, mumps and rubella.
That vaccine has eliminated untold suffering, but the idea that it can trigger
autism has taken hold among a small number of parents, who proselytize
energetically against vaccinating.
If there were any credible evidence of a risk, one could
not blame parents for fearing to vaccinate or Mr. Burton for using his position
to highlight the risk. But repeated large-scale studies have failed to find any
link between the vaccine and autism. Most recently, the Institute of Medicine
of the National Academy of Sciences, at Mr. Burton’s request, reviewed previous findings, and its panel found
no grounds for changing the vaccination schedule, although it urged continued
monitoring of that and other vaccine safety questions. Now Mr. Burton wants the
National Institutes of Health to study the issue again.
Autism, a tragic neurological disorder that can render
children unable to communicate or relate normally to others, appears to be on the
rise. A small percentage of cases is attributed to genetics or to prenatal
damage, but most cases are unexplained. Symptoms generally surface at about the
age childhood immunizations are given. But the autism rate has not grown in
tandem with immunization rates, and it is rising in places where rates of
immunizations are holding steady. Despite
this, the link hypothesis has developed a sturdy life, especially on the
Internet, to the point at which public health authorities fear holes could open
in the immunization safety net. In Britain, where the vaccine hypothesis has
had more press, experts are seeing a slight but worrying erosion in vaccination
rates.
A loss of confidence in vaccines would be catastrophic for
a society that has almost forgotten the horror of the many infectious diseases they
have nearly eradicated—not just mumps, measles and rubella, but polio,
diphtheria, whooping cough and others. Responsible government oversight of
vaccine safety is essential; these hearings don’t fit in that category.
