Committee on Government Reform - The Status of Research into Vaccine Safety and Autism
June 19, 2002 - 11:00 a.m.
2154 Rayburn House Office Building
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.
A while ago, in this area, there was an outbreak of whooping cough. I knew many mothers who vaccinated their children and these children got whooping cough. I knew many mothers who because of religious reasons did not vaccinate their children against whooping cough. These children in the same area, going to the same schools did not come down with whooping cough.
The big lie is that these vaccinations actually protect against the disease. They don't. No where in that article do they say that those who were not innoculated against measles were the ones that got the disease.
We have pro-choice in so many things, why not vaccination. If the vaccine is so good, people will choose it on its own merits. The fact of the matter is that it is worse than the disease. Autism is a living death, in many cases.
Those that seem to be screaming loudest against Wakefield's research are those that probably have a vested interest in doing so. Read the first paragraph of Wakefield's House statement to see what I mean.
I was particularly interested in his comments from his testimony about the MMR re-challenge work that he has done. Re-challenge studies are among the best tools a researcher has in associating cause with effect:
Re-challenge and biological gradient effects for MMR/MR vaccines A further key piece of evidence comes from examination of re-challenge and biological gradient effects for possible vaccine-related adverse events. Re-challenge refers to a situation where re-exposure of an individual to an agent (e.g. vaccine) elicits a similar adverse reaction to that seen following the initial exposure. The secondary reaction associated with re-challenge may either reproduce the features associated with the primary challenge, or may lead to worsening of the condition that was provoked or induced by the initial exposure. During the course of our clinical investigation we have observed that some children who received a second dose of MMR, or boosting with the combined measles rubella (MR) vaccine, experienced further deterioration in their physical and/or behavioural symptoms following re-exposure. In a report of April 2001, the Vaccine Safety Committee of the US Institute of Medicine (IOM) stated that, in the context of MMR vaccine as a possible cause of this syndrome, challenge re-challenge exposed would constitute strong evidence of an association[1]. In the context of adverse vaccine reactions, a biological gradient refers to an increasing severity of, or increased risk of developing, a particular disease outcome. More severe bowel disease in children with regressive autism who had received more than one MMR/MR would be an example of this. We have undertaken systematic evaluation of re-challenge and biological gradient effects in children with regressive autism who have undergone investigation at the Royal Free Hospital. Exposed children with normal early development & regressive autism who had received more than one MMR/MR - were compared with age and sex matched unexposed children with normal early development & with regressive autism who had received only one MMR but otherwise similar baseline characteristics to the exposed group. Comparisons included: secondary (2o) developmental/behavioural regression; 2o physical deterioration, prospective, observer-blinded scores of endoscopic & microscopic disease severity. In a preliminary analysis exposed children scored significantly higher than unexposed children for: (i) secondary regression on the basis of analyses performed at the different levels, including : q parental history q excluding those whose secondary regression occurred following publication of the 1st suggested MMR-autism link in 1998; and, q inclusion of only those for whom independent corroborative evidence of secondary regression was obtained from the records; (ii) secondary physical symptoms; (iii) presence of severe ileal lymphoid hyperplasia; and, (iii) presence and severity of acute mucosal inflammation. No measures of disease were worse in unexposed than exposed children. These data identify a re-challenge effect on symptoms and a biological gradient effect on severity of intestinal inflammation that provide evidence of a causal association between MMR and regressive autism in these children. |
Also of note is Dr. Arthur Krigsman's testimony. Dr. Krigsman of NYU offered supporting evidence of Dr. Wakefield's findings in that he has observed the same pattern of bowel disease in children with regressive autism. He plans to have the samples from his patient group independently tested for the presence of the measles virus.
Seems that the list of "quacks" supporting Dr. Wakefield is growing.
As I said to you on another thread, independent research into the CDC VSD database will be a critical factor in determining whether this journey Dr. Wakefield seems to be on is valid or just a wild goose chase. This is especially so since there simply isn't going to be a mad rush to step forward and duplicate Wakefield's results. Too many careers and too much vested interest to protect.
I got a trip to Aruba coming up in a couple of months, rubber. Wanna join me?;-)
Yeah sure. I remember in 1973 when NIMH researcher George Crane was called a quack by the research community when he was the lone voice writing about the neurotoxicity of antipsychotics. Today his "quack" views are enshrined in the PDR and the DSM.
Time will tell who's right. We need to hear more from independent researchers on this and less name-calling from the vested-interest "establishment."
So shall we put it on Pfizers tab or Eli Lillys?
You're right, but you've definitely gotten me interested.
How many papers need to be written and how much public health work needs to be done to refute these strange assertions
According to you, none. Tell you what, why don't you tell me what studies I need to read to come to the same conclusion you have. I promise you I'll read them. I can look them up, so don't go to too much trouble. Just something descriptive enough that will allow me to find it. Thx.
There is so much data out there that it's not worth me rewriting all the other guy's papers.
Heh, you're closer than you know. One of Art Bell's shows from just this past week consisted of several hours of conspiratorial ranting about vaccines, mercury, autism ... everything you see in this thread and much much more.
I'm not wasting any further time on idiotic rants.
You did read them, didn't you? You weren't just blowing smoke when you said:
I've reviewed the literature fully and the issue is about as moot as can be.(your post 21)
