Autism & Vaccines: A New Look At An Old Story .2
A Comprehensive Report
This is part 2 of a comprehensive report by the National Vaccine
Information Center on a matter of topical importance to the autism
community. It has been distributed to thousands of health care
professionals throughout the United States, including pediatricians, as well
as every member of every state legislature throughout the country and every
member of the US Congress.
Expenses for the production and distribution of the report has been
covered by the NVIC and by the generous contributions from the attendees
of the DAN! conference in San Diego last year.
We are reproducing the report in segments in the FEAT Daily Newsletter
over the next two weeks. The document in its entirety can be found at the
NVIC website.

Education, I.Q. and "Refrigerator Moms"
Kanner's young patients came from well-educated middle and upper class
families in Baltimore with mothers and fathers who were doctors, lawyers and
professors. In 1954, Kanner said, "we have not encountered any one autistic
child who came of unintelligent parents." This concentration of autistic
children in educated and professionally successful families led Kanner to
develop the "refrigerator Mom" theory as the cause of autism, theorizing
that the warm maternal instincts of educated working mothers was absent or
diminished. Embracing the popular psychiatric, Freudian themes echoed by
Kanner, for decades pediatricians were persuaded to blame mothers of
autistic children for being cold and emotionally rejecting, causing the
children in turn to coldly reject contact with other people.
By 1954, Kanner had started to modify his "Blame the Mother" stance in
recognition that the brothers and sisters of autistic children were often
well adjusted, high functioning children and suggested that the development
of autism was also a result of genetic or "constitutional inadequacies" as
well as bad parenting. By 1971, Kanner admitted Mom was not to blame.
But the damage had already been done. The rejecting parent theme was
taken up by psychoanalyst Bruno Bettleheim in various books and articles,
such as The Empty Fortress (1967). Bettleheim insisted the autistic child
was behaving in abnormal ways in retaliation against a rejecting mother who
had traumatized the child by failing to provide enough love or attention.
A Father Shows The Way
But even as Bettleheim's influence was growing, a California
psychologist and father of an autistic child, Bernard Rimland, Ph.D.,
already had taken on the psychiatric establishment which had dominated
autism research and treatment. In his landmark book Infantile Autism: The
Syndrome and Its Implications for a Neural Theory of Behavior published in
1964, Rimland methodically dismantled the psychoanalytic theory of autism
and argued for a biological, specifically a neurological, basis for autistic
behavior. He documented the similarities between brain injured children and
autistic children, liberating parents from the destructive guilt associated
with having an autistic child and pointing autism research in the direction
it should always have taken: investigation into the biological mechanisms
underlying the brain and immune dysfunction symptoms and their possible
causes.
After founding the Autism Society of America (ASA) in 1965 and
establishing the Autism Research Institute (ARI) in 1967, Rimland began
distributing a questionnaire to parents of autistic children. Some 33 years
later, his databank includes information on more than 30,000 cases of autism
from around the world. In analyzing the data for age of onset of autism, he
discovered that before the early 1980's, most of the parents reported their
children first showed signs of abnormal behavior at birth or in the first
year of life. But after the mid-1980's, there was a reversal of this
pattern. The numbers of parents reporting that their children developed
normally in the first year and a half of life and then, suddenly, became
autistic, doubled. Today, said Rimland, "the onset-at-18 months children
outnumber the onset-at-birth children by 2 to 1."

Class, Vaccines and Autism
Rimland, like Kanner, noticed early in his research that autistic
children often came from intelligent, well-educated parents who were
successful professionals in their communities. Upper middle class families
in America have always sought out and received quality medical care.
Children, whose parents are well educated are the most likely to take full
advantage of the latest developments in medicine. This would have been
especially true in Kanner's day as two miracle drugs of the 20th century -
antibiotics and new vaccines - elevated trust in and reliance upon
pharmaceuticals to a new plateau.
In the early 1940's, state-of-the-art pediatric medical care would
have included a smallpox vaccination plus a separate dose of diphtheria
vaccine. In 1944, pertussis vaccine was recommended for all babies. By 1947,
the American Academy of Pediatrics (AAP) recommended routine use of the new
combination DPT vaccine. By 1958, Kanner's case files contained more than
100 cases of autism.
In 1969, M.S. and W.C. Goodwin reported a dramatic upsurge of autism
cases in their pediatric psychiatric practice after 1964. By 1964, the
well-cared-for American child was getting simultaneously vaccinated with DPT
as well as polio vaccine at two, four, six and 18 months of age (the
inactivated polio (IPV) was licensed in 1955 and the live virus oral polio
(OPV) vaccine was licensed in 1963). After 1959, more than three million
children were injected with the combination DPT-IPV shot (Quadrigen) before
it was pulled off the market in 1968 for safety and efficacy reasons. By the
mid-1960's, many state-of-the-art pediatric practices were also giving
babies the new live virus measles vaccine, which had been licensed in 1963
and was routinely used by 1965.
More Vaccines and More Vaccinations
By 1979, a combination live virus measles-mumps-rubella (MMR) vaccine,
which was licensed in 1971, had been added to the routine child vaccination
schedule and given to children at 12 to 15 months of age; federal grants
were being given to states to provide free DPT, polio and MMR vaccines to
children in public health clinics; and the CDC was encouraging states to
enforce mandatory vaccination laws to raise national vaccination rates. By
1979, rubella vaccine, which had been licensed in 1969 for use in children
also began to be routinely administered to mothers in hospitals after giving
birth (Preblud, 1985; Tingle, 1986).
In 1988, the CDC added haemophilus influenza b (Hib) vaccine to the
child vaccine schedule; in 1991 the CDC recommended the recombinant
hepatitis B vaccine be used by all newborn infants and children; in 1993 the
combined DPTH vaccine was licensed; and in 1995, the live varicella zoster
(chicken pox) vaccine was put on the market.
Almost Three Dozen Doses By Age Five
In 1999, the average American child regardless of the parent's
educational level or ability to pay was being injected with hepatitis B
vaccine at 12 hours of age and 1 month; with DPT or DTaP, Hib, OPV or IPV at
two and four months; with DPT/DTaP, Hib, OPV/IPV and hepatitis B at six
months; with live varicella zoster at 12 to 18 months; with MMR and Hib at
12 to 15 months; with DPT/DTaP, OPV/IPV at 18 months; and with DPT/DTaP,
MMR, OPV/IPV between four and six years for a total of 33 doses of 10
different viral and bacterial vaccines by the age of five. National
vaccination rates for children under age three have climbed from between 60
to 80 percent in 1967 for DPT, polio and measles vaccine to 90 percent in
1999 for DPT, polio, MMR, and Hib vaccines. Vaccine coverage rates with core
vaccines for five-year-old children entering kindergarten have reached 98
percent plus in many states.
Vaccination today is not just a medical intervention afforded by the
rich and taken advantage of by the well educated but an equal opportunity
extended to the rich and poor, the educated and uneducated alike, and
enforced in the U.S. by state mandates. Although cases of autism in the 1940
's and 1950's were concentrated in the upper and upper middle classes, today
the growing numbers of children affected with autism come from all social
classes.
Encephalitis: From Disease and Vaccines
Inflammation of the brain (encephalitis, encephalomyelitis,
encephalopathy) has been documented for more than 200 years in the medical
literature to be caused by viral and bacterial infections as well as the
vaccines containing altered viruses and bacteria. Smallpox infection can
involve brain inflammation with symptoms ranging from fever, vomiting,
drowsiness, and convulsions which progress over a period of one to four
weeks, sometimes ending in coma and death.
The vaccinia virus used by Edward Jenner in 1796 to prevent smallpox
was found to cause acute disseminated encephalomyelitis (ADEM) within one to
six weeks of smallpox vaccination estimated to occur in 1 in 5,000 persons.
Smallpox vaccination has also been reported to cause a slow, subacute
persistent viral infection that can emerge years after vaccination (Adams et
al, 1972) and end in death. (The myelin sheath that encloses many nerve
fibers helps the transmission of neural impulses and if the myelin sheath is
damaged through traumatic injury, metabolic disorders, toxic insult, viral
or bacterial infection or vaccination, it can cause degeneration or
demyelination).
Pasteur's Rabies Vaccine
Rabies, a viral disease of the central nervous system (CNS), can take
10 days to a year for the virus to reach the brain but, once it does,
encephalomyelitis symptoms include excessive motor activity, excitation,
agitation, confusion, combativeness, bizarre aberrations of thought,
seizures and other CNS dysfunction. After Pasteur began to inject patients
with rabies vaccine in the 1880's, it became obvious that brain inflammation
was a side effect. Encephalitis and polyneuritis has been estimated to occur
in as many as 1 in 400 vaccinated individuals, with Hemachudha, Griffin, et
al in 1987 presenting evidence for an immune-mediated mechanism involving
antibodies to myelin basic protein.
Measles and EEG, Behavior Changes
Within three weeks of even a mild measles infection, one in 1,000
cases can develop encephalomyelitis with signs including fever, headache and
drowsiness. Residual brain damage from measles encephalitis ranges from
mental and behavior changes, including subtle changes in performance, to
seizure disorders and mental retardation. Changes in the
electroencephalogram (EEG) have been demonstrated in half of those who have
had measles but do not show other signs of CNS dysfunction.
Measles virus infection has long been known to be associated with
demyelinating disorders. Guillain-Barre syndrome (GBS) has been reported
following measles disease (Lidin-Janson, 1972) and after measles vaccination
(Grose and Spigland, 1976). Optic neuritis and multiple sclerosis in
children has also been reported after measles disease and measles
vaccination (Riikonen, 1989). In 1973, Landrigan and Witte described 45
cases of encephalitis occurring between 6 and 15 days following measles
vaccination.
Persistent Measles Virus Infection
Subacute sclerosing panencephalitis (SSPE) is a rare subacute
encephalitis complication of measles infection which causes slow
demyelination of the brain over a one to two year period and ends in death.
It has also been reported after measles vaccination (Schneck, 1968). In
1994, the Institute of Medicine concluded that the live measles virus
vaccine can cause death from measles vaccine strain viral infection.
In 1998, officials of the National Vaccine Injury Compensation
Program, Public Health Service (Pediatrics; March 1998) found that a causal
relationship exists between live measles vaccine and encephalopathy after
analyzing cases of children who received measles vaccine alone or in the
combination MMR shot and, within 15 days of vaccination, suffered neurologic
signs that progressed to death or mental regression, retardation, chronic
seizures, motor and sensory deficits and movement disorders.
An outbreak of aseptic meningitis in Brazil has been linked to the MMR
vaccine (Am J Epidmiol, 2000). A research team found there was a sharp
increase in the number of cases of aseptic meningitis three weeks after a
1997 mass MMR vaccination campaign in northeastern Brazil. The researchers
"conservatively estimated" that the risk of aseptic meningitis is 1 in about
14,000 MMR vaccine doses. (A type of brain inflammation involving the
meninges, aseptic meningitis can be caused by viruses and bacteria as well
as stroke, lead poisoning, and vaccine reactions (Berkow, 1987). Most people
recover from aseptic meningitis without damage but some are left with muscle
weakness or other motor dysfunction).
Mumps, Rubella and Brain Inflammation
Mumps has been known to cause meningitis and encephalitis since the
eighteenth century. Russell and Donald, observed in 1958 that "the clinical
resemblance between mumps
encephalitis and the encephalitis which may follow measles, varicella and
rubella, and the fact that the histological appearance of perivascular
demyelination are common to them all, suggest that they arise from the same
pathological process. The nature of this process is unknown, but it may be a
non-specific allergic reaction to virus protein (Miller and Evans, 1953) and
similar lesions have been produced experimentally by the injection of brain
material with adjuvants (Lumsden, 1949).".
There have been many case reports and studies documenting meningitis
within three weeks of mumps vaccination (Brown, 1991), and after MMR
vaccination (Sugiura and Yamada, 1991), primarily with the Urabe vaccine
strain virus. There have also been reports of meningitis after vaccination
with the Jeryl Lynn mumps vaccine strain (Ehrengut and Zastrow, 1989) now
used in MMR vaccine.
Rubella disease is caused by an RNA virus and, although mild in
children, it can be transmitted from mother to fetus in utero and cause
enchephalitis and devastating harm to the unborn child, including mental
retardation, hearing and vision loss, heart and neuromuscular deformity. In
the rubella epidemic that swept the U.S. in 1964, an estimated 20,000 to
30,000 children whose pregnant mothers were infected with rubella were born
severely damaged and a high rate of classic and "partial" autism was
observed in those children by Chess in 1971. In 1977, Chess reported that
the rate of autism in children born with congenital rubella from the 1964
epidemic was equivalent to a rate of "412 per 10,000 for the complete
syndrome of autism and 329 for the partial syndrome, giving a combined rate
of 741 per 10,000" compared to the rate of autism in children without
congenital rubella syndrome (estimated in 1966 to be 2.1 cases of autism per
10,000 children (Lotter, 1966).
Encephalitis and Mild Brain Damage
In the 1920's, when a mini-epidemic of "von Economo's encephalitis"
swept through Europe and America, doctors found that some of those who
recovered were left with minimal brain damage including changes in behavior,
restlessness, insomnia or disturbed sleep patterns, irritability, short
attention span, emotional disorders and seizures. In 1934, Kahn and Cohen
described a group of children with the inability to sit still or
concentrate, which they attributed to exposure to von Economo's
encephalitis.
Japanese encephalitis can cause permanent CNS changes including
personality and behavior problems featuring emotional lability and
irritability, speech disorders, hemiplegia, mental retardation and seizures.
Chicken pox and mumps infections can, in rare cases, progress to
encephalitis and brain inflammation has also been reported to follow chicken
pox and mumps vaccines.
Polio and CNS Damage
Poliomyelitis is caused by an enterovirus in which one to two percent
of infected individuals develop disease in the central nervous system, and
fewer go on to have residual paralysis or die. Likewise, within one to six
months of receiving the live attenuated polio vaccine, complications can
occur which, according to the Institute of Medicine (IOM) in 1994, can cause
Guillain-Barre syndrome as well as vaccine strain viral infection ending in
paralysis and death. In both cases, the polio virus invades the CNS and
destroys neurons. (Since 1979, the only cases of paralytic polio which have
occurred in the US have been caused by the live oral polio vaccine (OPV) and
it is no longer recommended by the CDC or AAP, having been replaced by the
inactivated polio vaccine (IPV) which cannot cause polio in the person
vaccinated or a person who comes into contact with that person's body
fluids).
Bacteria Also Cause Brain Inflammation
But brain inflammation is not only caused by viruses and viral
vaccines. Bacterial infections and bacterial vaccines also can cause brain
inflammation ending in permanent CNS damage.
Encephalitis has always been the most dreaded complication of
pertussis or whooping cough, with endotoxin and pertussis toxin in the B.
pertussis bacteria responsible for most of it. Pertussis toxin is one of the
most lethal toxins in nature and can cross the blood brain barrier when
conditions are right. It has long been known that a severe case of whooping
cough accompanied by brain inflammation symptoms such as fever, lethargy,
vomiting and seizures can be fatal or cause permanent brain damage ranging
from seizure disorders and mental retardation to learning, personality and
behavioral disorders (Lurie & Levy, 1942).
Pertussis Toxin Lethal
Since the 1950's, scientists conducting experiments have added
pertussis toxin to a solution of nerve tissue and injected it into
sensitized mice to deliberately induce brain inflammation. However pertussis
toxin is also thought to be involved in acquiring immunity to the disease,
both after natural infection and after vaccination (Pittman, 1979).
Vaccine developers continue to have a problem making a pertussis
vaccine that contains pertussis toxin inactivated enough to be safe but
active enough to be immunogenic, which is why the purified DTaP vaccine is
associated with the same CNS complications as the whole cell DPT vaccine,
although they are reported to occur at a much lower rate with DTaP. (The
more reactive whole cell DPT vaccine has not been taken off the market and
it is still being used by some pediatricians, especially in the combination
DPTH (DPT plus Hib). Parents who want the purified DTaP for their children
must ask for it by name.)
