“Mercury in Medicine – Are We Taking Unnecessary Risks?”
July 18, 2000
2154 Rayburn House Office Building
Washington, D.C.

       For the last year, the Government Reform Committee has been looking at issues regarding vaccine safety, research, and policy.  A few people have tried to portray this investigation as “anti-vaccine.”  Nothing could be further from the truth.  Safe, effective vaccines save lives.  On the other hand, vaccines that have not been thoroughly tested and reviewed can be dangerous.  The rotavirus vaccine was a good example.  The Government and manufacturers ignored the warning signs.  A lot of babies were injured and required surgery.  One baby died before the vaccine was pulled from the market.

Is it irresponsible to ask questions about why that happened?  Of course not.

We have a lot of doctors who serve on Federal advisory committees who have serious conflicts-of-interest problems.  They’re allowed to vote on vaccines made by companies that they get money from. 

Is it irresponsible to ask questions about conflicts of interest?  Of course not.

Today we’re holding a hearing about why mercury is put into vaccines that are given to children.

Is that irresponsible?  Of course not.

If someone holds hearings about mismanagement of the Department of Education, that doesn’t mean they’re anti-education.  That means they want our education system to be as well run as possible.  That is the way that I feel about our vaccine policies.  No area is so sacrosanct that the world will come to an end if we ask some sensible questions and expect to get some sensible answers.

I think this kind of oversight will make our vaccine program stronger, not weaker.

This spring, we held a hearing about possible connections between autism and the MMR vaccine.  We heard lots of testimony on both sides of the issue.  After the hearing, I sent a letter to Secretary Shalala.  So did Congressman Waxman.  We both asked her to put together a panel of the best experts in the field to look at this issue.  That was May 16 –two months ago.  No response.

That’s intolerable.  If your position is that we should base our policies on good science and good research, then fine.  I agree with you 100 percent.  But if you are not willing to do the research, if you’re not even willing to ask the questions, then we have a real problem on our hands. 

I believe that our primary focus in vaccine policy should always be what is best for the children.  We need to insure that only vaccines that are truly needed to protect the public are added to the Childhood Immunization Schedule.  At no time should the interests of vaccine developers be a higher priority than our children’s health and well being. 

Vaccines are the only drugs that Americans are required by a Government agency to take.  It is thus imperative that the Federal Government ensures the safety of these mandated vaccines.  Each state sets a schedule for the vaccines a child must receive in order to attend school or day care.  The states rely on the Federal Government for guidance on which vaccines should be mandated.  The Federal Government is also the largest purchaser of vaccines.

That brings us to today’s hearing topic – mercury in medicine.  This would seem to many to be a “no-brainer.”  We all know that mercury is a toxic substance.  Long term exposure to low levels of mercury has been linked to mental retardation, cerebral palsy, and central nervous system disorders.  We assume that the

FDA would protect our children from exposure to any level of mercury through drugs.  But that hasn’t been the case. Thimerosal was first marketed in 1930 and has become the most widely used preservative in vaccines.  It is present in over 50 licensed vaccines.  

The FDA recently acknowledged that in the first six months of life children get more mercury than is considered safe by the EPA.  The truth is that sometimes kids go to their doctor’s office and get four or five vaccines at the same time.  My grandson received vaccines for nine different diseases in one day.  He may have been exposed to 62.5 micrograms of mercury in one day through his vaccines.  According to his weight, the maximum safe level of mercury he should be exposed to in one day is 1.51 micrograms.  This is forty-one times the amount at which harm can be caused. 

How much mercury are kids being exposed to at once? 

One would think that the FDA would have moved aggressively to remove vaccines that contained mercury from the market immediately.  They did not. 

On July 9, 1999, the American Academy of Pediatrics and the United States Public Health Service issued a joint statement recommending the removal of thimerosal from vaccines.[1]  On May 31, 2000, the Food and Drug Administration notified vaccine manufacturers that their review of mercury compounds in drugs and foods concluded that reducing or eliminating thimerosal from vaccines is merited.[2]  However, there has been no mandatory action.  These vaccines are still in use. 

The FDA continues to allow the mercury-containing vaccines to remain on the market.  Today, over eight thousand children in America may be given a toxic dose of mercury in their vaccines.[3]   

Many parents who have contacted the committee are concerned about other ingredients as well, including formaldehyde, MSG, and aluminum.  We have also been contacted by many individuals who have concerns about mercury in dental amalgams.  While this is not the focus of today’s hearing, it certainly warrants discussion as well. 

Congress directed the Environmental Protection Agency to contract with the National Research Council to prepare recommendations on the appropriate dose for mercury exposure.  That report was released on July 11[4].  While the FDA relies on the Agency for Toxic Substances and Disease Registry’s dosing level for mercury of 0.5 micrograms per kilogram of body weight per day is significantly higher than the EPA’s dose of 0.1 microgram per kilogram of body weight.  In that report, it was confirmed that the EPA’s reference dose is correct.  We will hear from Dr. Vascken Aposhian, University of Arizona at Tuscon, one of the scientists who worked on this report. Ramona Trovato will testify on behalf of the Environmental Protection Agency.

Section 413 of the Food and Drug Administration Modernization Act of 1997[5] required the FDA to compile a list of drugs and foods that contain intentionally introduced mercury compounds, and provide a quantitative and qualitative analysis of the mercury compounds in this list.  The Act also requires the agency to compile the list and provide the analysis within two years after the date of its enactment on November 21, 1997.  Dr. William Egan will be testifying on behalf of the Food and Drug Administration.

While thimerosal has previously been ruled by the FDA to fit the  “generally recognized as safe” standard, when the FDA conducted their Over the Counter (OTC) drug review they changed their minds.  The FDA determined that mercury compounds used as active ingredients in Over the Counter drug products were not found to be “generally recognized as safe.”  Additionally the FDA has not approved any mercury containing compounds as food additives and does not consider any mercury containing compounds to be “generally recognized as safe.” [6]  On their own website, the FDA states, “lead, cadmium, and mercury are examples of elements that are toxic when present at relatively low levels.”[7] 

How is it that mercury is not safe for food additives and Over the Counter drug products, but it is safe in our vaccines and dental amalgams?

Dr. Roger H. Bernier, Associate Director for Science at the National Immunization Program, Centers for Disease Control and Prevention will testify regarding the recent discussion of the Advisory Committee on Immunization Practices regarding thimerosal. 

Autism is a syndrome characterized by impairments in social relatedness and communication, repetitive behaviors, abnormal movements, and sensory dysfunction.  Autism may now affect 1 in 150 U. S. children.   We will hear from Dr. Marie Bristol-Powers of the National Institutes of Health regarding the existing research in autism.  The characteristics of autism and of mercury poisoning are strikingly similar.[8]

          Dr. Stephanie Cave, a physician from Baton Rouge, Louisiana will be testifying about the mercury toxicity she is seeing in the 200 autistic children she has as patients.

          Autism strikes families from a diverse background.  We will hear from five parents today:  Elizabeth Birt of Chicago, an attorney and the mother of an autistic child will be testifying about the need to remove mercury from all vaccines and a citizens petition that is being presented to the FDA making this request.

Several parents with scientific and medical backgrounds have written a report entitled, “Autism: A Unique Type of Mercury Poisoning.” Three of these parents will be testifying today.  The lead author of the report is Sallie Bernard of Cranford, New Jersey.  Lyn Redwood of Tyrone, Georgia is a nurse practitioner, and Albert Enayati, of Paramus New Jersey is a chemist.   Dr. Sharon Humiston, a doctor with an autistic child will also be testifying.

          Our children are the future of this country.  As a Government we have a responsibility to do everything within our power to protect them from harm, including insuring that vaccines are safe and effective. Every day that these mercury-containing vaccines remain on the market is another day we are putting eight thousand children at risk.

The Record will remain open until August 1, 2000.

Mercury in Medicine.  Are We Taking Unnecessary Risks?

  http://www.house.gov/reform/hearings/healthcare/00.07.18/redwood.htm

Chairman Burton, Congressman  Waxman, and Committee  Members.

My name is Lyn Redwood.  I reside in Atlanta, Georgia with my husband Tommy and three children, Hanna, Drew and Will.  My husband and I are both health care professionals. My husband is a Physician and I’m a Nurse Practitioner.  I also hold a Masters Degree in Community Health Nursing and I’m a member of our County's Board of Health and local Planning Commission.   

My son Will weighed in at close to 9 lbs at birth. He was a happy baby who ate and slept well, smiled, cooed, walked and talked, all by one year.  Shortly after his first birthday he experienced multiple infections, lost speech, eye contact, developed a very limited diet and suffered intermittent bouts of diarrhea. He underwent multiple evaluations and was initially diagnosed with a global receptive and expressive speech delay and later with Pervasive Developmental Disorder, a form of autism. 

I would have never made a correlation between my son’s disability and vaccines until July 1999 when I read that a preservative, thimerosal, utilized in some infant vaccines, actually contained 49.6% mercury.  The report went on to say that the FDA had  determined that “infants who received thimerosal-containing vaccines at several visits may be exposed to more mercury than recommended by Federal Guidelines for total mercury exposure.”  As health care providers my husband and I constantly receive notices that adverse events have been reported with a drug or a product safety sheet has been revised.  Why were no such notices sent out informing us that thimerosal preserved vaccines were exceeding federal guidelines for mercury exposure in infants? 

It was in light of this information that I reviewed my son’s vaccine record and my worse fears were confirmed.  All of his early vaccines had contained thimerosal.  From my research on mercury I have found it to be a potent human toxicant which is especially damaging to the rapidly developing fetal and infant brain.  While acceptable levels for exposure are published by Federal Agencies, mercury is a poison at any level.

The dose thought to be safely allowed on a daily basis by EPA is 0.1mcg per kilogram of body weight per day. At 2 months of age my son had received 62.5 mcg of mercury from 3 infant vaccines.  According to EPA criteria, his allowable dose was only 0.5mcg based on his weight.  He had received 125 times his allowable exposure on that one day.  These large injected bolus exposures continued at 4, 6, 12 and 18 months to a total mercury exposure of 237.5 mcg.  I also discovered that the injections that I received during the first and third trimesters of my pregnancy and hours after the delivery of my son to prevent RH blood incompatibility also contained mercury.

Knowing that the major effect of mercury compounds was neurotoxicity, I questioned if these exposures could account for my son’s regression and disability.  Since he was now 5 ½ years old, it would be difficult to know what his mercury levels had been at that time.  It was then that I remembered having kept a lock of hair from his first haircut at 20 months of age.  Heavy metal analysis detected 4.8 ppm mercury in his hair. The allowable levels being less than 1 ppm.  The EPA action level in hair is 1 ppm and 5 ppm is considered diagnostic for mercury toxicity.  Since my son has never eaten fish or seafood nor had dental amalgams, I have  no other identifiable source for his mercury levels outside of thimerosal exposure from his vaccines and my RhoGAM injections.

Since last fall when I discovered my son’s mercury toxicity, I have spent every free moment further investigating this issue. As a nurse and a member of the Board of Health for our county, I felt an urgency to share my findings and concerns about thimerosal with other professionals.  I did research, I made phone calls, I wrote letters and actually went in person to meet with FDA and CDC officials to voice my concerns and present data on documented levels of mercury in many other children with developmental delays who were also exposed to thimerosal in their vaccines. All of my efforts seemed to fall on deaf ears.

On June 21, 2000 I attended the Advisory Committee for Immunization Practices meeting held in Atlanta.  At that meeting a study was presented that looked at Vaccine Safety Datalink information and thimerosal exposure in over 120,000 children.  The key findings of this study were significant associations between thimerosal exposure and ADD, tics, speech and language delay and neuro-developmental delays in general.  A panel of experts who were convened to review the data concluded  “The findings support a statistically significant (albeit weak) association, but that the implications are profound.”

Unfortunately, ACIP chose not to give preference to thimerosal free vaccines, even though vaccine manufacturers assured there was enough supply available to meet vaccine needs the first six months of life.  From the comments made by ACIP committee members it was apparent that political and economic concerns for the vaccine program took precedence over the health, safety and welfare of the children it is charged to protect. One committee member even remarked that giving preference to thimerosal free vaccines may result in reduced public confidence in vaccines.  From my own personal perspective, just the opposite has occurred. 

You may hear today from some officials that the mercury exposure from medicinal sources is insignificant. The fact is that neurological damage is documented to occur in infants at these levels of exposure. You may also hear that these levels only exceed EPA guidelines the first six months of life. That is because the data was inaccurately averaged over a six month time period. As any independent toxicologist will tell you, mercury has a long half life and because of its inherent pharmocokinetics, you cannot legitimately calculate the effect of a bolus dose as if it were ingested in small amounts over a longer period of time. To make a simple analogy, what the FDA is trying to assert is that giving someone two tylenol a day for 60 days has the same effect of giving them 120 tylenol all at once in one day! This, of course, defies common sense, much less sound medical practice.

The truth is, vaccines, are often the single largest source of mercury exposure postnatally in infants, but nowhere in the mercury literature of EPA, FDA or ATSDR are these products even identified as being a source of exposure. When I spoke with one official from EPA he commented that my son’s exposure was very high and was rather sympathetic, but since it was not an environmental exposure, his agency could not get involved. So whom do I turn to for help?

Over 1 year ago the FDA, AAP, and the Public Health Service called for the immediate elimination or reduction of thimerosal from vaccines.  But the sad truth is that while some progress has been made, infants continue to be injected with one of the most neurotoxic metals on earth in excess of Federal Safety guidelines as I speak here today, and the responsible agencies are unwilling to address this issue.

We are in the midst of an autism epidemic and children diagnosed with learning disabilities continue to increase daily. The statement that there is “no evidence of harm” does not equate to no harm having occurred. The truth is that we have not adequately looked or we just refuse to see. A recent national news article which addressed these concerns reported that some may say we don’t have a smoking gun, but the truth is there are bullets all over the floor.

Millions of children have been needlessly exposed to toxic agents from Federally sponsored vaccine programs and have suffered neurological damage. This problem has become so pervasive in our society that few are left untouched, as chairman Burton well knows.  It is time for someone to step forward and acknowledge these facts and provide the science to fully investigate what has happened to our children and what can be done to help them.

Thimerosal

Despite the fact that thimerosal preservative has been effective in lowering the risk that vaccines could be contaminated by bacteria leading to serious infection, the United States Public Health Service agencies, including NIH, FDA, HRSA, and CDC, working collaboratively with the American Academy of Pediatrics and the American Academy of Family Physicians, took action in mid-1999 to begin removing thimerosal preservative from the vaccine supply. While the risk of harm from this source was only theoretical, the decision was made as a precautionary measure. The elimination of thimerosal preservative from vaccines was judged a feasible means of reducing an infant’s total exposure to mercury in a world where other environmental sources of exposure may be more difficult or impossible to eliminate.

As a result of this action, all manufacturers of routinely recommended licensed pediatric vaccines are now producing for the U.S. market only vaccines that are thimerosal-free or contain trace amounts of thimerosal. The vaccines are supplied in single-dose vials which eliminates the need for a preservative.

The United States has been a world leader in the development and licensing of new vaccines and has placed a high priority on producing vaccines which meet the highest standards for safety and efficacy. These standards pertain not only to the active ingredients, which elicit protective immune responses, but also to the preservatives such as thimerosal. Thimerosal, an ethylmercury containing preservative used since the 1930's, is added to some vaccines because it is very effective in preventing bacterial contamination and resulting infections in vaccine recipients.

In mid-1999 administration of a combination of vaccines that contained thimerosal as a preservative was recognized as exceeding one federal guideline for mercury exposure. It is important to note that the form of mercury used in thimerosal is ethylmercury. Although toxicity data are lacking for ethylmercury, it is currently assumed that methylmercury guidelines are appropriate to use in this situation. Even though there was no evidence of possible harm caused by ethylmercury exposure from immunizations, the United States Public Health Service agencies, including NIH, FDA, HRSA, and CDC took action, working collaboratively with the American Academy of Pediatrics and the American Academy of Family Physicians. Last summer a goal was set for the removal or significant reduction of thimerosal as a preservative from all vaccines routinely administered to children in the first year of life. While the risk of harm from this source was only theoretical, the decision to set a goal to remove thimerosal was made as a precautionary measure. Given the concern about the health effects of mercury of any sort, the elimination of mercury from vaccines was judged a feasible means of reducing an infant's total exposure to mercury in a world where other environmental sources of exposure may be more difficult or impossible to eliminate.

During the year since the goal was set, progress in removing or reducing thimerosal in vaccines has been outstanding. The United States has now achieved a pediatric hepatitis B vaccine supply from two manufacturers that is free of thimerosal as a preservative, and, as of this month, a Haemophilus influenzae type b vaccine supply from all four manufacturers is available that is free of thimerosal as a preservative. For DTaP vaccines, there are four manufacturers, one of which has produced a vaccine that is already free of thimerosal, and at least one other is expected to produce a vaccine without thimerosal as a preservative within six to nine months. Measles, mumps, rubella, varicella, inactivated polio, and the recently licensed conjugate pneumococcal vaccines have never contained thimerosal. Based on our progress over the past year, the maximum amount of mercury an infant may be exposed to from routine immunizations has been reduced by 60 percent.

Thus, by early 2001, the United States is expected to have obtained an adequate vaccine supply for the routine pediatric vaccines that is completely free of thimerosal as a preservative.
