Opening Statement
Chairman Dan Burton
Committee on Government Reform
The Status of Research into Vaccine Safety and Autism
June 19, 2002
In April the Committee conducted a hearing reviewing the epidemic of
autism and the Department of Health and Human Services (HHS) response.
Ten years ago, autism was thought to affect 1 in 10,000 individuals in
the United States. When the Committee began its oversight investigation
in 1999, autism was thought to affect 1 in 500 children. Today, the
National Institutes of Health (NIH) estimates that autism affects 1 in
250 children.
In April we looked at the investment our Government has made into
autism as compared to other epidemics. We showed in that hearing that
the CDC and NIH have not provided adequate funding to address the issues
in the manner that our Public Health Service agencies have used to
address other epidemics.
After our hearing, I joined with my colleagues on the Coalition on
Autism Research and Education to request from our appropriators that at
least 120 million dollars be made available in FY 2003 for autism
research across the NIH and at that an additional $8 million be added to
the CDCs budget for autism research.
Giving more money to research is not the only answer though.
Oversight is needed to make sure that research that is funded will
sufficiently answer the questions regarding the epidemic, how to treat
autism, and how to prevent the next ten years from seeing the statistic
of 1 in 250 from becoming 1 in 25 children.
High quality clinical and laboratory research is needed now, not five
or ten years from now. Independent analysis of previous epidemiological
and case control studies is needed as well.
We have learned that a majority of parents whose children have
late-onset or acquired autism believe it is vaccine-related. They
deserve answers. We have also learned that the parents have been our
best investigators in looking for both causes of autism and for
treatments.
It has been parents who have formed non-profit organizations to raise
research dollars to conduct the research that the CDC, the FDA, and the
NIH have neglected to do. We have heard from many of these parents in
the past, Elizabeth Birt, Rick Rollens, Shelley Reynolds, and Jeanna
Smith, to name just a few. Each of these parents had healthy babies who
became autistic after vaccination.
I might have been like many of the officials within the public health
community denying a connection - had I not witnessed this tragedy in
my own family. I might not have believed the reports from parents like
Scott and Laura Bono, Jeff Sell, Jeff and Shelly Segal, and Ginger
Brown, who came to me with pictures, videos and medical records. I might
have been like so many pediatricians who discounted the correlation
between vaccination and the onset of fever, crying, and behavioral
changes. Because both of my grandchildren suffered adverse reactions to
vaccines, I could not ignore the parents plea for help. I could not
ignore their evidence.
My only grandson became autistic right before my eyes shortly after
receiving his federally recommended and state-mandated vaccines. Without
a full explanation of what was in the shots being given, my talkative,
playful, outgoing healthy grandson Christian was subjected to very high
levels of mercury through his vaccines. He also received the MMR
vaccine. Within a few days he was showing signs of autism.
As part of our investigation, the Committee has reviewed ongoing
concerns about vaccine safety, vaccine adverse events tracking, the
Vaccine Safety Datalink (VSD) Project, and the National Vaccine Injury
Compensation Program. I have joined with Congressman Weldon, Congressman
Waxman and 32 other members of Congress in introducing HR 3741, the
National Vaccine Injury Compensation Program Improvement Act of 2002 to
realign the compensation program with Congressional Intent.
In todays hearing, we will receive a research update from several
previous witnesses as well as new research findings that further support
a connection between autism and vaccine adverse events. We will learn
more about both the possible link between the use of the
mercury-containing preservative thimerosal in vaccines and autism, as
well as autistic entercolitis resulting from the Measles-Mumps-Rubella
(MMR) vaccine.
Through a Congressional mandate to review thimerosal content in
medicines, the FDA learned that childhood vaccines, when given according
to the CDCs recommendations exposed over 8,000 children a day in the
United States to levels of mercury that exceeded Federal guidelines. Is
there a connection between this toxic exposure to mercury and the autism
epidemic? We will hear from Dr. James Bradstreet and Dr. Vera Stejskal
on this issue.
We have twice received testimony from Dr. Andrew Wakefield regarding
his clinical research into autistic entercolitis. We will learn today
that not only has he continued to conduct clinical research, but that
this research is confirming the presence of vaccine-related measles RNA
in the biopsies from autistic children. Dr. Wakefield - like many
scientists who blaze new trails - has been attacked by his own
profession. He has been forced out of his position at the Royal Free
Hospital in England. He and his colleagues have fought an uphill battle
to continue the research that has been a lone ray of hope for parents
whose children have autistic entercolitis. Dr. Arthur Krigsman is
joining us as well today to discuss his clinical findings of
inflammatory bowel disorder in autistic children. He will share with us
his initial findings as well as discuss his research plans currently
with his Institutional Review Board for approval.
Do the epidemiological and case control studies, which the CDC has
attempted to use to refute Dr. Wakefields laboratory results, answer
the autism-vaccine questions honestly? Epidemiologist Dr. Walter Spitzer
is back today to answer this question. What else is needed to prove or
disprove a connection?
Unfortunately, rather than considering the preliminary clinical
findings of Dr. Wakefield as a newly documented adverse reaction to a
vaccine, the CDC attempted to refute these clinical findings through an
epidemiological review. While epidemiological research is very
important, it cannot be used to disprove laboratory and clinical
findings. Valuable time was lost in replicating this research and
determining whether the hypothesis was accurate.
Officials at HHS have aggressively denied any possible connection
between vaccines and autism. They have waged an information campaign
endorsing one conclusion on an issue where the science is still out.
This has significantly undermined public confidence in the career public
service professionals who are charged with balancing the dual roles of
assuring the safety of vaccines and increasing immunization rates.
Increasingly, parents come to us with concerns that integrity and an
honest public health response to a crisis have been left by the wayside
in lieu of protecting the public health agenda to fully immunize
children. Parents are increasingly concerned that the Department may be
inherently conflicted in its multiple roles of promoting immunization,
regulating manufacturers, looking for adverse events, managing the
vaccine injury compensation program, and developing new vaccines.
Families share my concern that vaccine manufacturers have too much
influence as well. How will HHS restore the publics trust?
Access to the Vaccine Safety Datalink (VSD)
One of the primary topics to be discussed at this hearing is access
to the Vaccine Safety Datalink. (VSD). To help fill scientific gaps, the
CDC formed partnerships with eight large health maintenance
organizations through an agreement with the American Association of
Health Plans to continually evaluate vaccine safety. This project is
known as the Vaccine Safety Datalink (VSD) and includes medical records
on millions of children and adults. Up until this year, access to data
from the VSD has been limited to researchers affiliated with the CDC and
a few of their handpicked friends. This good old boys network
practice has predictably led to questions about the objectivity of the
research and the fairness of the results.
The VSD data should be made available to all legitimate scientific
researchers so that independent studies can be conducted and results
verified. This database contains a wealth of data involving millions of
patients over a ten-year period. If properly utilized, it can help
researchers study vitally important questions about the safety of
vaccines, the effects of mercury-based preservatives in childhood
vaccines, and many other questions.
The Committee first raised this issue with the CDC two years ago. For
two years the CDC delayed. Six months ago, we were informed that the CDC
was developing a plan to expand access to the database. Finally, in
February of this year, after a great deal of prompting from the
Committee, Dr. Robert Chen, Chief of Vaccine Safety and Development at
the National Immunization Program, informed Committee staff that the CDC
had finalized its plan and that it was poised to put it into effect.
Under this plan, any legitimate scientist could submit a proposal to the
CDC to conduct research using VSD data and access to the data would be
provided along with some basic safeguards.
In preparation for todays hearing, Committee staff asked the CDC why
the plan described to us in February had not yet been put into effect.
The staff was informed that the plan had been put into effect. However,
there had been no public announcement. How are researchers supposed to
know about the availability of the data if there is no announcement? It
took two years of prodding by this Committee to get the CDC to open up
access to the database. For four months it appears that the CDC didnt
inform anybody but this Committee of the datas availability.
That doesnt make it appear that the CDC is making a good faith
effort to open up this database. It looks to me like the CDC is trying
to do the bare minimum that they have to do to get us off their backs.
Thats not acceptable. Thats why I insisted that Dr. Chen be here
today. I just want to ask him why they didnt tell anyone about the
database being available. Id like to know how he expects researchers to
use this data if nobody tells them its available.
Dr. Roger Bernier is here from the CDC to testify about these issues.
He is accompanied by both Dr. Chen, the creator of the VSD Project and
Dr. Frank DeStefano, the CDC official who is also a co-author of the MMR
IBD study. They are here to address our questions on the VSD project
and the vaccine- autism research. The CDC employees are accompanied by
Dr. Stephen Foote of the National Institutes of Health and Dr. William
Egan of the Food and Drug Administration.
As representatives of the people, we have a responsibility to ensure
that our public health officials are adequately and honestly addressing
this epidemic and its possible links to vaccine injury.
I look forward to hearing from our witnesses today. Our hearing
record will remain open until July 3.
I now recognize the ranking minority member, Mr. Waxman for his
opening statement.
