U.S. Senate,
Committee on Veterans' Affairs,
Washington, DC, December 8, 1994
During the last few years, the public has become aware of several examples where U.S. Government researchers intentionally exposed Americans to potentially dangerous substances without their knowledge or consent. The Senate Committee on Veterans' Affairs, which I have been privileged to chair from 1993-94, has conducted a comprehensive analysis of the extent to which veterans participated in such research while they were serving in the U.S. military. This resulted in two hearings, on May 6, 1994, and August 5, 1994.
This report, written by the majority staff of the Committee, is the result of that comprehensive investigation, and is intended to provide information for future deliberations by the Congress. The findings and conclusions contained in this report are those of the majority staff and do not necessarily reflect the views of the members of the Committee on Veterans' Affairs.
This report would not have been possible without the dedication and expertise of Dr. Patricia Olson, who, as a Congressional Science Fellow, worked tirelessly on this investigation and report, and the keen intelligence, energy, and commitment of Dr. Diana Zuckerman, who directed this effort.
John D. Rockefeller IV, Chairman
Appendix -- Survey of 150 Persian Gulf War Veterans
Many experiments that tested various biological agents on human subjects, referred to as Operation Whitecoat, were carried out at Fort Detrick, MD, in the 1950's. The human subjects originally consisted of volunteer enlisted men. However, after the enlisted men staged a sitdown strike to obtain more information about the dangers of the biological tests, Seventh-Day Adventists who were conscientious objectors were recruited for the studies. (Note 18) Because these individuals did not believe in engaging in actual combat, they instead volunteered to be human subjects in military research projects that tested various infectious agents. At least 2,200 military personnel who were Seventh-Day Adventists volunteered for biological testing during the 1950's through the 1970's. (Note 19)
Unlike most of the studies discussed in this report, Operation Whitecoat was truly voluntary. Leaders of the Seventh-Day Adventist Church described these human subjects as "conscientious participants," rather than "conscientious objectors," because they were willing to risk their lives by participating in research rather than by fighting a war. (Note 20), (Note 21)
When the Department of Defense began preparations for Desert Shield and Desert Storm in 1990, officials were extremely concerned about the need to protect U.S. troops against chemical and biological weapons that were believed to have been developed by Iraq. However, the DOD lacked drugs and vaccines that were proven safe and effective to safeguard against expected weapons, such as soman and botulism.
Under the Food, Drug, and Cosmetics Act, all vaccines and medical products must be proven safe and effective by the Food and Drug Administration (FDA) in order to be sold and distributed in the United States, or used by U.S. troops. However, DOD officials were interested in using a botulinum toxoid, which is a vaccine to prevent botulism, that was not approved by FDA. They also wanted to use pyridostigmine bromide, a medication to protect U.S. troops against chemical nerve agents. Although approved by the FDA for treating patients with a neurological disorder called myasthenia gravis, pyridostigmine is not proven safe or effective for repeated use by healthy persons under any circumstances, and is normally unavailable in doses that would be likely to be safe for healthy individuals. (Note 77)
Under current law, the unapproved vaccine and the investigational use of pyridostigmine for healthy individuals could only be administered under an Investigational New Drug (IND) procedure. (Note 78) Under an IND, any individual who is given the investigational product must give informed consent, i.e., must be told of the potential risks and benefits of the product, orally and in writing, and choose freely whether or not to participate. In addition, the IND requires that the medical product be distributed under carefully controlled conditions where safety and effectiveness can be evaluated.
In August 1990, the DOD contacted FDA to review regulatory restrictions of DOD's plan to use pyridostigmine and botulinum toxoid for U.S. troops in the Persian Gulf. The major focus of the meeting was informed consent. The DOD sought a waiver of requirements for informed consent for the use of pyridostigmine bromide and botulinum toxoid, arguing that these investigational products had well-established uses and were safe. They also claimed that there were no reasonable alternatives. According to minutes of the meeting, "FDA expressed some concern about liability and the need to comply with the regulations," and FDA's Deputy Director for Drug Review "pointed out the need to establish an appropriate investigational framework to collect observational data and evaluate the military medical products in question." (Note 79)
In summary, DOD informed FDA that they did not want to abide by informed consent regulations, and FDA officials pointed out that pyridostigmine and botulinum toxoid were investigational and that there are laws regulating how they can be used. DOD claimed that "under the DOD directive the Secretary of Military Departments [could] dictate the use of unapproved FDA regulated products" in the Persian Gulf, but "DOD's current position is that this not their primary choice at this time." (Note 80)
The issue was debated by the two agencies for several months. Finally, at a meeting on December 31, 1990, an agreement was reached. According to minutes of that meeting, DOD officials agreed that the botulism vaccine would be administered by trained individuals with a health care background, and that information would be provided orally "at minimum, and in written form if feasible, to all personnel receiving the vaccine." (Note 81) Officials from the DOD said that the feasibility of distributing an information sheet would depend on many factors, and would vary from location to location within the military theater of operation. DOD officials "reiterated that at least verbal [sic] information would be provided to each person receiving the vaccine."
The FDA Informed Consent Waiver Review Group recommended that pregnant women be excluded from receiving the vaccine and that information about the vaccine be "posted at places where vaccine is administered." However, DOD argued that pregnant women would be at greater risk from exposure to botulism toxins than to the vaccine, and FDA agreed that instead of excluding pregnant women, a statement would be added to the information sheet stating that, "If you are pregnant, it is not known if this vaccine will hurt the unborn baby, however, most vaccines do not." (Note 82)
In their application for a waiver, DOD described the safeguards that would be in place regarding the distribution of the botulism vaccine. In addition to oral warnings regarding the vaccine, DOD promised that the soldiers would be observed for 30 minutes after receiving the vaccine, and if possible, they would also be checked again 48 hours later. In addition, DOD claimed that they would provide all three vaccine injections and stated that all three were necessary to provide protection.
FDA granted the waiver on a temporary basis, concurring that obtaining informed consent during wartime is not feasible in a specific military operation involving combat or the threat of combat. (Note 83) On January 8, 1991, Dr. David Kessler, FDA Commissioner, wrote to the Assistant Secretary of Defense for Health Affairs regarding the waiver for informed consent for pyridostigmine. In his letter, Dr. Kessler agreed that since there was "no available satisfactory alternative therapy" for protection against organophosphorus nerve gas, he would "concur with your assessment that informed consent is not feasible." This agreement was apparently based on DOD officials' promise to "provide and disseminate additional information to all military personnel concerning the risks and benefits of pyridostigmine." (Note 84)
Although FDA agreed to waive informed consent for both the pyridostigmine bromide and the botulism vaccine, the Assistant Secretary of Defense for Health Affairs notified Dr. Kessler on March 15, 1992, that "Central Command" had decided that the vaccine would be administered on a voluntary basis. (Note 85) However, based on interviews with 150 Persian Gulf War veterans by Committee staff (Appendix), 88 percent of those who said they received a botulism vaccine were told they had no choice.
According to the DOD, all 696,562 U.S. troops in the Persian Gulf War were issued pyridostigmine bromide as a pretreatment for nerve agent poisoning, and officials estimate that approximately two-thirds took the drug for varying periods of time. Of 150 who were interviewed by Committee staff, 73 took pyridostigmine and 74 percent of them were told they could not refuse to take it. Approximately 8,000 individuals received botulinum toxoid in the Persian Gulf. Given the high proportion who have reported that they had no choice, it appears that hundreds of thousands of U.S. troops were ordered to take an investigational drug or vaccine without having the opportunity to refuse.
Although DOD officials convinced FDA they need not offer choice, DOD had promised to provide extensive information about potential risks orally and in writing. In addition to being ordered to take an investigational product without informed consent, most Persian Gulf War military personnel surveyed claim they received no oral or written information about the drug or vaccine, despite the DOD promises to FDA to provide information about potential risks. These claims are supported by a survey conducted by the Department of Defense following the Persian Gulf War. Sixteen of 23 selected Persian Gulf War medical personnel surveyed by the DOD indicated that no information on the side effects of pyridostigmine bromide was provided to those who were ordered to take the drug. (Note 86) These medical personnel were responsible for 8,366 military personnel during the Persian Gulf War.
There are two kinds of risks associated with lack of information. One is a lack of trust. In the survey conducted by Committee staff, 14 of 73 (19 percent) Persian Gulf War veterans who had been ordered to take pyridostigmine bromide indicated that they did not take all the pyridostigmine bromide they were ordered to take, fearful that the drug was responsible for the symptoms they experienced (Appendix). Because no one would answer their questions about the safety and efficacy of the pyridostigmine bromide, they feared they were receiving a potentially harmful drug. Therefore, if pyridostigmine bromide had been crucial for surviving nerve agent exposure, an unknown number of individuals would have lacked protection because they had received inadequate information about the drug.
The other risk is that even if serious side effects were rare, they could have been treated if medical personnel were able to diagnose the problem. For example, Carol Picou, a nurse who was stationed in the Gulf for 5 months, had obvious side effects from the pyridostigmine starting on the third day that she took it. These side effects included incontinence, drooling, and blurry vision, among others. The side effects became worse 1 hour after she took each pill. One day, she did not take the pill as scheduled, and the side effects stopped; unfortunately, her commanding officer ordered her to continue taking the pills, and watched to make sure she swallowed them. She was ordered to take the pills for 15 days. She now has many permanent medical problems, including incontinence, muscle weakness, and memory loss, that might have been avoided had she been allowed to stop taking the pills. (Note 87)
Similarly, Lt. Col. Neil Tetzlaff had immediate side effects when he started taking pyridostigmine bromide on the plane ride over to Saudi Arabia. His nausea and vomiting became so severe that he needed emergency surgery to repair a hole in his stomach. When he became ill, the military doctor told him to continue to take the pills, because the doctor apparently did not know that nausea and vomiting were known side effects. According to Tetzlaff's sworn testimony, the doctor acted as if the pyridostigmine was as safe as a cough drop. (Note 88)
In addition to any intentional removal of information, veterans' service medical records are difficult to find. According to the U.S. General Accounting Office, veterans' service medical records can potentially be in thousands of locations. (Note 156) The DOD has attempted to simplify the retrieval of medical records by modifying the route for medical records of individuals who have left the military. The simplified route was initiated for the Army in October 1992, for the Navy in February 1994, and for the Air Force and Marines in late 1994. Although the new procedures should simplify the process, the GAO concluded that the possibility of misplaced medical records remains because there are still thousands of locations where records could be found within the new system.
