Armed Services Smallpox
Vaccination: Medical Research and Military Necessity
By Thomas May
The Bush administration's
decisions regarding smallpox vaccination of military personnel, health
workers, and the general public have raised a number of human rights
issues. Smallpox vaccination is a relatively dangerous and invasive
therapy that, although offering protection against one of history's
most devastating contagious diseases, poses significant risks and side
effects. Potential complications include encephalitis, death, and a
number of side effects serious enough to require a doctor's care in
one of every 10,000 cases.
Smallpox vaccination
was discontinued in the United States in the 1970s because its benefits
no longer warranted exposing individuals to its serious risks. Today
these potential risks are exacerbated by the fact that the vaccine for
this program is either "old" vaccine that has been in storage
for more than thirty years, or "new" vaccine manufactured
through cell culturing and considered experimental. Studies of the safety
and efficacy of the old vaccine in dilute doses, conducted during the
past year primarily on healthy college-student volunteers, resulted
in about one-third of the vaccine recipients becoming sick enough to
miss work or school as a result of the vaccine. No deaths occurred.
Since January 2003, approximately 350,000 military personnel have also
been vaccinated with the old vaccine. Although only about 3 percent
of vaccine recipients have required sick leave, there have been fourteen
cases of myocarditis ranging from mild to severe (an incidence rate
of one in 20,000) and a number of other side effects, including two
reported deaths.
Vaccination of armed
services personnel raises a serious human rights concern. Although vaccination
of health workers and the general public involves voluntary, individual
decisions (at least as of this writing), smallpox vaccination of armed
services personnel is mandatory absent a medical exemption. Those who
do not qualify for medical exemptions may be disciplined if they refuse
vaccination. Such punishment can be serious: service members who refused
anthrax vaccination during the 1990s were sometimes court-martialed
or discharged. The problem posed by mandatory vaccination is basic:
military service does not negate humanity and basic human rights.
Most important in
this context, however, is that the vaccination program has aspects that
are research oriented. As outlined in the Nuremberg Code, participation
in medical research must be voluntary and military personnel are not
excepted, even in times of combat. Pentagon rules against nonvoluntary
medical research have been explicitly in place since at least 1925.
Military personnel often risk their lives to protect the nation's security;
however, this risk should not be unlimited, and individual human rights
must be upheld. And, although the current military vaccination program
is not primarily medical research, a society that seriously values human
rights should take care to recognize the research implications of the
program and be aware of potential conflicts of interests.
Rationales
Smallpox vaccination
of armed forces personnel has a sound military rationale. Of course,
soldiers and those who support them must be able to function even if
attacked by chemical or biological weapons. Contagious disease among
troops has been influential in many wars and battles. The United States
suffered more casualties from disease during World War II than from
combat.
The use of biological
weapons also has a long military history. After the Iraqi invasion of
Kuwait in 1990, recognition of a new era in possible biological warfare
led the Department of Defense to request an exemption from normal FDA
informed-consent requirements, for combat situations in which consent
is "not feasible." This exemption was granted on a drug-by-drug
basis in FDA Rule 23(d) during the first Gulf War. Most recently, command
officers in Iraq expressed significant fears that biological or chemical
weapons would be employed in the conflict, although there were no chemical
assaults as of early May 2003. Protective suits providing immunity from
chemical and biological agents were found in Iraqi positions, indicating
a possible plot to use them.
Noncompliance by
military personnel to the smallpox vaccination program could pose a
number of problems. The most obvious is widespread contraction of the
disease during a biological attack, which could require significant
medical attention and resources. Even in the absence of biological attack,
unvaccinated troops pose logistical problems: those who are vaccinated
with the live vaccine can spread the infection or might require separate
quarters from unvaccinated troops.
Military Medical
Research
The United States
has an unfortunate history of using military personnel for medical research,
such as Walter Reed's yellow fever research in the early 1900s. The
most informative incident in the context of exposing military personnel
to unknown risks involved the military's testing of troops after nuclear
explosions in the 1950s. A test to measure psychological effects of
atomic blasts required troop deployment near an A-bomb detonation. Although
the Advisory Committee on Human Radiation Experiments concluded that
the primary motive for troop deployment in this instance was training
for combat readiness, the involvement of medical personnel throughout
the exercise cast doubt about its purity of purpose. The motivation
driving an exercise might itself be multidimensional.
The question of
preemptive smallpox vaccination before a biological attack has been
in flux. See Jon Cohen and Martin Enserik, SCIENCE MAGAZINE, vol. 298,
no. 5602. In devising a pre-event smallpox vaccination strategy, the
Bush administration received conflicting advice from groups with differing
objectives. Significant public and media voices called for universal
access to vaccination. However, the Advisory Committee on Immunization
Practice (ACIP), a group charged with offering smallpox immunization
recommendations to the DHHS and the CDC, initially recommended that
at most 20,000 first responders be vaccinated prior to an actual bio-terror
event using this agent, later expanding its recommendation to approximately
500,000 health workers. The Bush administration eventually settled on
a sort of middle ground, three-phase plan, with immediate vaccination
of 500,000 health workers and 500,000 military personnel in the first
phase, vaccination of an additional 10 million emergency personnel (including
police and firefighters) in the second phase, and eventually moving
to a third phase in which vaccination would be available to the entire
population.
The three-step plan
has been hailed as a compromise that allows later decisions to be revised
in light of information gathered in previous phases. See William Foege,
Can Smallpox Be as Simple as 1-2-3?, WASH. POST, Dec. 27, 2002. The
administration seems well aware of this: in late November 2002, senior
aides to President Bush indicated that a final decision concerning universal
vaccination would likely be delayed until more information about adverse
reactions and the ability to treat them had been gathered from vaccination
of health workers and military personnel.
In this regard,
vaccination of military personnel has become a significant issue, given
that objections to pre-event smallpox vaccination have been widespread
among health workers and many hospitals have refused to vaccinate their
employees. The health worker vaccination program thus is far behind
schedule: although officials had hoped to vaccinate 500,000 health workers
before March 1, 2003, by the deadline only 12,690 volunteers had come
forward. See Ceci Connolly, Smallpox Vaccine Comes Full Circle, WASH.
POST, Mar. 16, 2003. In contrast, the mandatory armed services vaccination
program has moved along according to plan, as evidenced by the following
statement from William Winkenwerder Jr., M.D., assistant secretary of
defense for health affairs: "Our smallpox vaccination program expanded
rapidly and effectively to include more than 350,000 people. The program
continues to go well, and has been administered in a thorough, careful
and professional manner. We continue to experience the types of reactions
that we expected overall. Close monitoring has afforded these individuals
prompt, effective care." Although the ACLU carefully monitored
the administration's vaccination plan through the end of 2002 and advocated
for protections for health workers who choose not to be vaccinated,
it has remained largely silent concerning mandatory vaccination of military
personnel.
Medical research
clearly is one aspect of military smallpox vaccination, even if it is
not necessarily a prime motive in its implementation. We would be negligent
not to use information available from an actual sample to guide broader,
general public vaccination policy. But it does present potential conflicts
of interest that should be monitored by human rights organizations.
What evidence we
have indicates that protection of troops and their combat readiness
are the focus of the military's vaccination program. First, the DOD
indicated that armed services personnel were given the old FDA-licensed
vaccine rather than the experimental one. See Release, available at
www. defenselink.mil/news/ Dec2002/b12132002_bt634-02.html. But if medical
research relevant to broad public vaccination is indeed part of the
plan, testing the new vaccine would have been included.
Second, the smallpox
vaccination program is consistent with the world's general and the military's
specific focus on biological and chemical weapon preparedness. Troops
routinely are vaccinated for a variety of potential agents, many of
which have no relevance to the public. Finally, of course, there are
valid concerns about biological or chemical terrorist attacks following
the war with Iraq. Given the sacrifices already made by armed services
personnel, we owe to them a special concern to see that their basic
human rights are respected.
