Two specific vaccines come to mind, hepatitis A and hepatitis B. I will not
go into a long-winded scientific process and simply state that the chance of an
infant or child getting either hepatitis A or hepatitis B is close to none or
nonexistent. When the potential for exposure does exist, those risk factors are
easily identified. Even more disturbing is that hepatitis A causes a
self-limiting infection and does not cause chronic disease. It is my opinion
that parents should be made aware of the risks and benefits of each vaccine
where the chance for infection during infancy is minimal to nonexistent.---Ronald

I would like to take this opportunity to thank you for the invitation to
speak to this committee regarding issues related to vaccines, public safety, and
personal choice. My name is Ronald Kennedy, and I am a professor of microbiology
and immunology and obstetrics and gynecology at the University of Oklahoma
Health Sciences Center. I am a research scientist and teach medical and graduate
students.
My education has taken me from Connecticut, where I was born, to New Jersey,
to Hawaii, where I received my master's and doctoral degrees, Houston and San
Antonio, TX, and finally Oklahoma City.
My training is in microbiology and immunology and I have been working in the
area of vaccinology since 1981, when I first started working on the immune
response to hepatitis B surface antigen, the component of the hepatitis B
vaccine.
Since that time I have performed basic and applied research as it relates to
a variety of viral, bacterial and cancer vaccination strategies. Included in
these efforts were studies to develop and/or improved vaccines to hepatitis B
virus, the human immunodeficiency virus, HIV, hepatitis C virus, and simian
virus 40, among others a virus that been recently associated with cancer in
humans.
Because of my expertise in animal models for infectious diseases,
particularly non-human primate models, I've also performed a number of
collaborative studies with investigators on vaccines for haemophilus influenza
type B, group A and group B streptococcus and meningococcus, among others.
As a number of these infectious diseases cause diseases in newborns and
infants, I have become aware of the difference between how newborns respond to
vaccination when compared to an adult.
I consider myself pro-vaccine. However, growing up in the field of
vaccinology as I have, I am aware of a number of issues and considerations that
should be brought forth when it comes to vaccines, public safety, and personal
choice.
I would like to briefly mention three issues as it relates to the subject of
this hearing.
The first is a lack of a mechanism to study the basis for adverse reactions
to vaccines.
The second is, how can we improve vaccine safety, particularly when
immunizing infants?
The final issue is that certain vaccines are just not appropriate and have
not been tested well enough to mandate mass vaccination of infants, and this
deals with informed consent and the parents' right to personal choice.
Regarding the lack of a mechanism to study the basis for adverse reactions
to vaccines, I along with several colleagues have submitted grant applications
to the National Institutes of Health to study the basis and mechanism of adverse
reactions seen as a result of the hepatitis B vaccine. We made three attempts.
In each attempt the grant application was not considered for funding. The
reasons of the peer review panel were the application was descriptive and a
fishing expedition. We had compelling evidence but no direct cause and effect,
and limited preliminary data.
Page 109 PREV PAGE TOP OF DOC
As someone who has been funded continuously from the National Institutes of
Health since 1984 and who has served on grant review panels for the National
Institutes of Health since 1987, I was aware that such comments were a kiss of
death. More importantly, I did not disagree with the panel's perception of the
grant application. However, it was the nature of the subject matter. Since
everyone has a perception that vaccines are completely safe, why would they want
to study adverse reactions?
If the National Institutes for Health or Centers for Disease Control and
Prevention will not support research by investigators outside their institutions
into the basic mechanisms of adverse reactions of vaccines that are presently
being used to immunize infants, perhaps the pharmaceutical companies who make
the vaccines would fund such work by outside investigators. Honestly, I do not
think that the vaccine manufacturers would be interested in supporting efforts
that might show that their product is harmful.
I would urge you to provide research funds that are currently unavailable to
study serious adverse reactions to vaccination such as those seen with hepatitis
B.
My second issue is how can we make vaccines safer, particularly in infants?
In my opinion, this requires more substantial testing, a requirement that each
lot of vaccine be tested in non-human primate models for safety and comparative
potency. Many of the present vaccine products have bypassed non-human primate
studies and gone directly from rodent studies into human clinical trials. This
was based on cost and comparability issues.
Additionally, other vaccines have shown problems in non-human primate
models, and these were ignored and the product went into human clinical trials
anyway.
It is important to test vaccines in immunologically similar animals and in
an outbred population like us, particularly when addressing issues like
long-term safety and comparable potency of a given vaccine lot.
My final issue relates to whether certain vaccines are appropriate for
infant immunization and whether parents should be informed about the risk versus
benefit of vaccination. More importantly, the physician who administers that
vaccine is probably not aware there are any risks.
Page 110 PREV PAGE TOP OF DOC
Two specific vaccines come to mind, hepatitis A and hepatitis B. I will not
go into a long-winded scientific process and simply state that the chance of an
infant or child getting either hepatitis A or hepatitis B is close to none or
nonexistent. When the potential for exposure does exist, those risk factors are
easily identified. Even more disturbing is that hepatitis A causes a
self-limiting infection and does not cause chronic disease. It is my opinion
that parents should be made aware of the risks and benefits of each vaccine
where the chance for infection during infancy is minimal to nonexistent.
Certain vaccines, such as the enhanced and inactivated polio, diphtheria,
tetanus, acellular pertussis, and the haemophilus influenza type B conjugate
vaccines have significantly reduced infant mortality and morbidity and should be
considered for infant immunization. However, other vaccines such as hepatitis B
may be more effective when given at a later age rather than at birth. Informed
consent for vaccines such as hepatitis A and hepatitis B should be considered
and parents allowed to choose based on their perceived risk to benefit from
vaccinating their infant.
To further illustrate my points, I would like to discuss adverse reactions
and the need to support funding activities. The example I am going to pick is
the whole cell pertussis vaccine.
This vaccine started for universal immunization of infants in developing
nations in the 1940's. The whole cell pertussis vaccine causes frequent systemic
symptoms such as irritability, lethargy, loss of appetite, and fever in 72 hours
following immunization in up to 50 percent of subjects. More severe reactions
include prolonged inconsolable crying, high pitched fever, screaming, fever
above 104.9 degrees Fahrenheit, febrile and afebrile seizures, and shock-like
states that can last up to 36 hours. In comparable trials, these adverse effects
were more common in DTP recipients than in DT vaccinees. This suggested that the
pertussis vaccine caused these reactions.
Page 111 PREV PAGE TOP OF DOC
The public believes that the whole cell pertussis vaccine causes brain
swelling and permanent neurologic damage and is widespread. However, scientific
epidemiologic data to support a casual relationship are said to be inadequate,
and this is simply not true.
Why is this the perception? First, there is no support for basic research
into adverse reactions. The data on the casual relationship and inadequate
nature to show a cause and effect, a lot of the data comes from the vaccine
manufacturers. New and improved vaccines should decrease the adverse reactions,
and the acellular vaccine is certainly associated with the lower incidence of
these reactions.
Will we ever understand the mechanism of how the whole cell vaccine produced
these side effects, and is there any association with neurologic problems? This
is unlikely, because this has been going on for 50 years, and what research
really has been done? My question is, why then is the whole cell vaccine still
being used?
Regarding the area of informed consent, I would like to quote from Chapter
17 in a textbook entitled Pediatric Infectious Disease, Principle and Practices.
The editors are two pediatric infectious disease specialists. The textbook was
published in 1995 and it is one that I use to teach medical students. In the
area of informed consent, I am quoting directly from the book.
Vaccines should be administered only after consent has been obtained from
the parent, guardian, or in some cases the vaccine recipient. In the United
States informed consent should be in writing and include an explanation of the
disease to be prevented, the benefits and risks of immunization and the side
effects that parents should look for following immunization.
Relative to requirements, again I am quoting from this chapter.
Page 112 PREV PAGE TOP OF DOC
Every time a public or private health care provider in the United States
administers a particular vaccine, it is required to provide a legal
representative of a child or any other adult or individual receiving a vaccine a
copy of the vaccine informed statement prepared by the CDC. In addition, the
names of the patient and parent, the date, site of immunization, dose,
manufacturing vaccine lot number, name of person who administers the vaccine,
and the place where the vaccine is administered should be recorded. This
information is absolutely important if an adverse reaction occurs following
immunization.
I think this is part of the problem with the adverse vaccine effects
reporting system. Health care providers are not required to obtain the signature
of the patient, parent or child's legal representative to acknowledge receipt of
the vaccine information statement. This is an absolute must.
I want to thank you for the opportunity to appear before this distinguished
committee. I would be happy to answer your questions at the end of the
testimony.
Dr. Kennedy, you said you submitted an application to NIH for a
research grant on the hepatitis B vaccine; is that correct?
Dr. KENNEDY. Yes. Myself and a number of other colleagues.
Mr. BURTON. You have had grants before? You have done research
before?
Dr. KENNEDY. Yes, since 1984. In fact I had the early grants on
looking at the immune response to the plasma-derived hepatitis B surface
antigen.
Mr. BURTON. Did they give any reason why they turned your grant
request down?
Dr. KENNEDY. Yes. Essentially that it was葉he term ''fishing
expedition'' means that you have a big juicy worm and you are throwing it out
there and hoping that someone will bite on it.
Mr. BURTON. Do you still have a copy of that grant application?
Dr. KENNEDY. Yes. I can provide that.
Page 121 PREV PAGE TOP OF DOC
Mr. BURTON. Can you give me a copy of it?
Dr. KENNEDY. Certainly can.
Mr. BURTON. I would like to have a copy as soon as possible.
Dr. KENNEDY. We did two additional revisions on the grant through the
process.
Mr. BURTON. I want to take a close look at it, if I could.
Dr. KENNEDY. OK.
Mr. BURTON. Maybe we will have a hearing on that grant application
itself and haul the people in here.
Dr. KENNEDY. I would rather you not. The process of NIH does work,
but I think the problem is the understanding of覧
Mr. BURTON. Wait just a minute. You say the process does work. How
long ago did you submit this grant application?
Dr. KENNEDY. 1997. And how we are supporting our present efforts to
address these issues relative to adverse reactions are kind of through private
funds.
Mr. BURTON. I don't mean to interrupt you, but my granddaughter
almost died. While your grant application sits there, how many other adverse
reactions have occurred like that and how many other parents may have lost their
child like the lady that was sitting over there? I think something as important
as that should get timely review. So I would like to see your application. You
let me worry about what to do with it, OK?
Dr. KENNEDY. OK.
Mr. BURTON. Let me ask Dr. Kennedy a question. What did you say
was the percentage of reactions to the pertussis vaccine within the first 48
hours?
Dr. KENNEDY. It was within the first 72 hours. Approaching 50
percent.
Page 123 PREV PAGE TOP OF DOC
Mr. BURTON. Fifty percent. Just a second. Fifty percent would have an
adverse reaction within the first 72 hours?
Dr. KENNEDY. I will provide you with the documentation that quotes
that.
Mr. BURTON. In many cases that is not of long duration.
Dr. KENNEDY. Right. Correct.
Mr. BURTON. It is something that comes and goes.
Do you have any percentages that show the adverse reaction that is of long
duration?
Dr. KENNEDY. No, I don't.
Mr. BURTON. So we really don't know. You know that there is an
adverse reaction that is pretty substantial within the first 72 hours in half of
the cases where they give those shots.
Mr. BURTON. I think that is a very good point, doctor.
Who manufactures the DTP vaccine?
Dr. KINSBOURNE. Lederle.
Dr. KENNEDY. Wyeth Lederle Pediatric Vaccines it is now called.
Mr. BURTON. Is that the only one that manufactures that?
Dr. KENNEDY. No. There are a couple others that make the whole cell
pertussis. I don't know it off the top of my head.
Dr. KINSBOURNE. Connaught is another company.
Mr. BURTON. Those are both domestic companies here in the United
States?
Dr. KINSBOURNE. I think Connaught is largely Canadian.
Dr. KENNEDY. It's Pasteur Merieux Connaught, but they have a
manufacturing facility in the United States, in Pennsylvania.
Mr. BURTON. You may not know this. I may have to check into this in a
later hearing or something. Do you know if they give any funds or grants or
honorariums to anybody over at NIH or CDC?
Mr. BURTON. Thank you. I would like to have that information if I could.
I just can't for the life of me fathom why that one vaccine is still on the
market and being manufactured and sold here and used in the United States. I
just don't understand that.
Can you explain that, Dr. Kennedy?
Dr. KENNEDY. I can maybe address the situation relative to the issue
of combination vaccines and why it may still be there. There were studies done
where they were combining the DTaP vaccine with the haemophilus influenza type B
glyco-conjugate vaccine, and a number of studies, both in non-human primate
models and in children, suggested that by combining and then giving it at a
single site that you would interfere with the ability to respond to the
haemophilus influenza type B [HIB] component, and the interference appeared to
be as a result of the acellular components.
Page 128 PREV PAGE TOP OF DOC
They do not know the mechanism. They knew if they took out the acellular
component and did a DT/HIB combination, it went fine. If they did the DTaP at
one site and then the HIB at the other site, the response was fine. If they did
the DTP/HIB, it appeared to be fine from a standpoint of responding to all four
of the components.
That could be one of the potential reasons, because some of the first
licensed combination vaccines are DTP/HIB, et cetera. It doesn't make sense, but
that's覧
Mr. BURTON. I'm not sure I comprehend if there is that kind of a
reaction in 50 percent of the cases in the first 72 hours why it's on the
market. I just do not understand that.
Do you have any reason why that would be the case, why they would keep that
on the market and continue to use it?
Dr. KENNEDY. Yes. If people are not complaining, you can make quite a
bit of money. What it comes down to the vaccine manufacturers, it's money if the
vaccine has already been produced; its already licensed.
Mr. BURTON. I know, but the people sitting behind you are not
influenced by these pharmaceutical companies. I'm sure of that. So why would
they not insist that it be taken off the market?
Dr. KATZ. This vaccine has been used for 40 years in this
country and its record of achievement has been a very successful one. What he is
describing as 50 percent is sore arms, sore legs, redness, fever. It's not
life-threatening reactions. It is more reactive than the acellular vaccine,
which is why most people have switched to the acellular vaccine, but these are
not life-threatening reactions that have been shown with the whole cell
pertussis to be any more than with any other acellular pertussis.
Mr. BURTON. These are FDA serious events in 1999. How many are in
here, 1,500 or more?
Page 129 PREV PAGE TOP OF DOC
Dr. Kennedy, of these 50 percent of the reactions were any of them pretty
severe?
Dr. KENNEDY. Yes. Quite a few were more severe, such as the high
pitched screaming, the crying, the fever, the shock-like syndrome.
Mr. BURTON. Running around and waving their arms and that sort of
thing?
Dr. KENNEDY. Yes, but the percentage I could not find.
Mr. BURTON. I will tell you that is exactly what happened to my
grandson. Exactly. He ran around waving his arms, a high pitched scream, waving
his arms up and down, and everything else, and he's autistic now.
I'm getting a little emotional about this. I think we will conclude this
hearing. But I want to tell you, this isn't the end of it.
We stand adjourned.

Mr. BURTON. So we really don't know. You know that there is an
adverse reaction that is pretty substantial within the first 72 hours in half of
the cases where they give those shots.
Dr. KATZ. We haven't used that vaccine for several years, Mr.
Burton. I think one of the things that I would love to point out to you is that
we do improve. We use the acellular vaccine in this country. The British
continue to use the vaccine that Dr. Kennedy has described. We haven't used it
for several years in this country.
Mr. BURTON. Is the DTP vaccine rather than the DTaP vaccine still
being used?
Dr. KATZ. The DTaP vaccine is being used, which has an infinitesimal
degree of reactivity compared to the DTP.
Mr. BURTON. The Department is behind you. Is the DTP vaccine still
being used in this country?
Mr. EGAN. Yes.
Mr. BURTON. It's still being used in this country. So, Dr. Katz, you
are incorrect. It is being used in this country.
Page 124 PREV PAGE TOP OF DOC
Dr. KATZ. If it is, it's in a very small percentage.
Mr. BURTON. It doesn't matter if it's your kid or your grandchild. If
they get a DTP vaccine and there is this adverse reaction that Dr. Kennedy is
talking about, it's of great concern to people, and we don't know whether it
leads to autism or not, but I have an autistic grandchild, and we've had a
number of other people that have seen tremendous problems with autism, and they
are still using that vaccine. You said you didn't think they were.
Dr. KATZ. I said they are still using it in the United Kingdom. They
don't use acellular pertussis vaccine.
Mr. BURTON. That's the United Kingdom. It's not the United States of
America.
Dr. KATZ. The World Health Organization is using it throughout the
world. We are the only country with the exception of Japan that made the switch.
Mr. BURTON. I know, but if it's causing adverse reactions that are so
severe that they affect people in the first 72 hours, 50 percent of them, it
should be something that is clearly looked into, and if there is any indication
it may cause autism, it should be really scrutinized.
Let me yield to the doctor here, and I will come back for some more
questions in a moment.
Mr. WELDON. Maybe our friends in the back can answer. I thought we
withdrew all the DPT, the cellular pertussis in the United States. It is still
licensed and it is still sold in the United States; is that correct?
Mr. EGAN. Yes.
Mr. WELDON. The FDA has never ordered that to be withdrawn? Why was
it not ordered to be withdrawn considering the higher incidence of side effects?
They felt that the side effects were not sufficiently life-threatening to
warrant it's withdrawal? Is that the rationale?
Page 125 PREV PAGE TOP OF DOC
For the record, Mr. Chairman, this pertussis issue is something that I
followed through the years, and I thought it was completely off the market. That
may be something that we may need to address.
If I may just go a little bit further. Dr. Kinsbourne, I really enjoyed your
testimony. You seem to get at a lot of the problems. Some of the issues that you
brought up I've had conversations with other scientists and some of the folks
that have already testified. The real bottom line issue is that there would have
to be very significant funding to get at these issues, because it would require
some very large studies that would have to be extended over many, many years,
correct?
Dr. KINSBOURNE. Yes, sir.
Mr. WELDON. Unless those studies are done, the questions that you
were posing are very difficult for us to answer, correct?
Dr. KINSBOURNE. Could not be answered until they are done. So the
sooner they are started the sooner they will be answered.
Mr. WELDON. The only other point I would like to make, Mr. Chairman,
is that if these studies are done, they may show that the vaccines are much
safer than is being alleged by some of the people who have provided testimony.
Until they are done, the public discontent that exists among some element in our
country is not going to go away, and it would be a mistake for us to just take
the face value of some who have testified alluding to the fact that all is well.
All may not be well, and the responsibility ultimately is going to fall to
political leaders in this country to make sure that the proper research is done.
I again want to thank you, Mr. Chairman, for holding these hearings.
Mr. BURTON. Thank you, doctor.
Mr. WELDON. Did you want to respond to my comments at all?
Dr. KINSBOURNE. Only to agree wholeheartedly. I think even if the
public were to see that the work was being done they would comply more willingly
with the mandates.
Page 126 PREV PAGE TOP OF DOC
Mr. WELDON. I will share this with you, Dr. Katz. In politics they
say perception is reality. If your opponent buys $500,000 worth of TV ads and
says that you cheated on your wife even though you have never cheated on your
wife, if the end result is that three out of four voters conclude that you
cheated on your wife and therefore they should vote against you and you lose
your reelection, that is reality. Even if our vaccines are extremely safe, if
the perception is growing out there that the vaccines are not safe and people
are starting to refuse their vaccinations, then we've got a problem. The way to
address this, though, is we need to better fund the agencies that need to do the
research.
Mr. BURTON. I think that is a very good point, doctor.
Who manufactures the DTP vaccine?
Dr. KINSBOURNE. Lederle.
Dr. KENNEDY. Wyeth Lederle Pediatric Vaccines it is now called.
Mr. BURTON. Is that the only one that manufactures that?
Dr. KENNEDY. No. There are a couple others that make the whole cell

honorariums to anybody over at NIH or CDC?
Dr. KATZ. No.
Page 127 PREV PAGE TOP OF DOC
Mr. BURTON. They do not?
Dr. KATZ. No.
Mr. BURTON. You're sure about that?
Dr. KATZ. I am sure that people at NIH are not allowed to take funds
even from universities. If I invite an NIH investigator to give a lecture at
Duke, I can't even pay him an honorarium.
Mr. BURTON. According to my assistant here, that isn't the case.
Dr. KATZ. Maybe you could ask Dr. Rabinovich. She works at NIH.
Mr. BURTON. They can accept honorariums, I believe. Can't you?
Dr. KATZ. Regina, do you want to respond?
Mr. BURTON. Aren't you the general counsel?
Dr. RABINOVICH. No. I'm here from the National Institutes of Health.
We do receive ethics training, and I've never accepted an honorarium. There may
be other situations in which intramural investigators can. We can provide that
information for you.
Mr. BURTON. I'd like to have that.
Dr. RABINOVICH. But I do not.
Mr. BURTON. Thank you. I would like to have that information if I
could.
