Today, I will be speaking about the
autoimmunity aspect of vaccines in autism, a medical condition that has been
largely ignored by the medical community and federal government for a very long
time and yet the incidence of autism is increasing at an alarming rate. An
estimated one-half of a million Americans, mainly children, and millions more
worldwide are known to suffer from autism, a heart-rending disorder that
severely impairs higher brain functions: social interaction, communication,
language, imagination and cognition. The disorder is a life-long mental
disability with devastating consequences for both the patient and his/her
family. Thus the financial burden is huge for the families who care for
children with autism.
Autism is an idiopathic brain
disorder, which simply means that the etiology of the disorder is not known.
And there is no single, clear-cut cause for autism. Causally speaking, I tend to think that autism is a complex disorder,
in which autoimmunity to brain plays a key role. Today, in spite of virtually
no funding available, autoimmunity is the most extensively investigated topic
of research in autism. This is by and large due to the fact that
autoimmunity is the prime target of therapy that has proven to be quite
effective in ameliorating autistic characteristics. Thus the autoimmunity
research, unlike the genetic research, has already significantly improved the
health and welfare of individuals with autistic disorder. I have recently
coined a term “Autoimmune Autism (AA)” to refer to a subset of autism that has
autoimmune etiology. Moreover, there are scientific reasons to think that this
subset may indeed be a result of vaccine injuries to children who display
autistic regression.
Autoimmunity is an abnormal
reaction immune reaction, in which the immune system becomes primed to react
against body organs. It’s a mosaic of highly complicated interactions and
networking between cells and molecules of the immune system. The body makes
autoantibodies against itself, resulting in damage to tissues and organs. The
“autoimmune” response is what happens in autoimmune diseases such as lupus, and
my research showed that a similar response my account for the brain
abnormalities found in people with autism.
Autoimmune diseases are
identified and characterized by many factors. The hallmark is the “organ-specific
autoantibodies” that have also been identified in people with autistic
disorder. To that end, I have recently summarized laboratory data of
approximately 400 cases (autistic and controls) and found that up to 80% of
autistic children have autoantibodies to specific brain structures, in
particular a brain protein known as myelin basic protein (MBP) of the myelin
sheath, a fatty coating that insulates nerve fibers and absolutely essential
for higher brain functions. These autoantibodies are present quite frequently
(65-85%) in autistic children, but only rarely (0-5%) in normal children and
other disease controls. Accordingly, I postulated that autism involves a
specific autoimmune response to MBP -- an immune assault that impairs myelin
development in the developing brain, thereby modifying the nerve cell functions
of the brain. Ultimately, by way of impaired wiring diagram in the brain, this
results into autism.
Autoimmunity is commonly
triggered by environmental exposures such as viral infections. Virus serology
(or virus antibodies) is an excellent tool for studying virus infections in
disease states. However, until recently, such studies had not been performed
for autism. Because of my ongoing research, I became interested in examining a virus
link with autoimmunity in autism. I recently raised two specific questions: (1)
Does autistic children have a hyperimmune response (or increase of antibodies)
for a specific virus? (2) Is there a relationship between virus antibodies and
brain autoantibodies in autism? I conducted a carefully designed study to
address these two questions. Succinctly, I made two very important
observations: first, there was indeed a hyperimmune response to a virus and it
was specifically for the measles virus (MV), but not for the other viruses
tested [human herpesvirus-6 (HHV-6), rubella virus (RV), and cytomegalovirus
(CMV)]; and secondly, there was an association between measles virus antibodies
and MBP autoantibodies (i.e., the higher the measles virus antibody level the
greater the chance of brain autoantibody). Few months earlier in the same year
(February, 1998), I had already found that many autistic children had
antibodies to a specific protein of the measles-mumps-rubella (MMR) vaccine
(MMR vaccine preparation). These viral antibodies were also related to positive
titers of brain MBP autoantibodies. This
was most probably the first laboratory-based evidence to link measles virus
and/or MMR vaccine to autoimmunity in children with autism. Collectively, these observations led me to
speculate that autism may be caused by a measles- or MMR vaccine-induced
autoimmune response. Unfortunately, due to lack of funding, I have not been
able to extend this research and the progress has been hampered.
As I made scientific presentation
of my initial findings, a vaccine-autism connection became even more apparent.
I compiled a nonscientific, anecdotal survey of vaccine-injured children with
“autistic regression” or autistic disorder, as reported by families. Surprisingly, up to 93% of the reported
cases had autistic symptoms shortly after vaccinations (52% post-MMR, 33%
post-DPT, and 8% post-MMR and/or post-DPT). The remaining 7% of the reported cases were not linked to any
vaccination at all. Indeed, if these numbers are reproducible, the data will lead to inescapable
conclusion that these vaccines can potentially cause autoimmunity in autism.
Quite candidly, this will not be first time that a vaccine has been linked to a
disease or disorder. There is quite a bit of literature linking vaccines to
autoimmune diseases. Furthermore, an epidemiological study just published in
JAMA (March 8th issue) described “extraimmunization” amongst
American children and considered it to be a contributing factor for the adverse
effects of the vaccines. And I think the vaccines and autism connection is no
exception to these adverse effects.
In summary, the rapidly accumulating evidence strongly implicates
autoimmunity in autism, which in many may result from a vaccine injury. There
is a possibility of an atypical measles infection in autism, but the evidence
also suggests a MMR vaccine infection. Without any reservation, I would
strongly recommend that this Congressional Committee reviews all the
information in bipartisanship, and explore
the possibility that drug companies never properly evaluated the safety of
vaccines in the first place. If this indeed were true then it becomes
imperative that we as a society must pay an immediate attention to this
problem; otherwise, an epidemic of autism is a real good possibility. There
should be no mistaking about it because autism is on a sharp rise and
vaccinations, especially the extraimmunization, could potentially explain this
rise. The onset of autism (or autistic
regression) post-immunization should no longer be regarded as merely a
coincidence with the timing of the vaccinations, as our federal health
officials continue to do. We must find new ways to curve adverse effects of
vaccines, including autism. Considering a population of 500,000 cases of
autism in the United States, the autoimmunity research, but not the genetic
research, has already had a great impact on the health and welfare of autistic
people. Since brain autoimmunity is found in up to 85% of cases, it can
potentially help an estimated 425,000 Americans. Indeed, many of them are
already reaping the benefits of the experimental autoimmune therapy. Thus there
is an urgent need to promote autoimmunity research in autism. This
recommendation is in contrast to the opinions held by the directors of the
federal agencies and major private foundations (Cure Autism Now and National
Alliance for Autism Research) who are erroneously committed themselves to fund
genetic research only. Finally, I urge the Government Reform Committee to
provide leadership for new solutions to the existing problems surrounding
autism research, and request the Committee Members to be visionary and offer
new hope to the people with autism -- The essence of life is to care.
