Smallpox
vaccine: Experts Urge Caution, Administration Pushes Hard
Sat, 29 Mar 2003
In our earlier Infomail today, the focus was on the
Administrations difficulty in recruiting volunteers for the
anthrax vaccine trial. This Infomail focuses on the determined
push to implement the smallpox vaccine program, despite the
advice of medical experts who urge caution. {See New York
Times and ABC News links, below]
The Washington Post reports (below) "federal health experts
are investigating at least 18 cases of possible cardiac
reactions, including three fatal heart attacks in recently
immunized military personnel and civilian health care
workers."
Despite the Administration's directive, the public is
clearly not following in step. The Post reports that New York
and Illinois have suspended the smallpox vaccine program
entirely, with individual hospitals in Florida, New Hampshire
and elsewhere doing the same. And in the District of Columbia,
the health department indicated that only three of the 11
health department workers scheduled for inoculation yesterday
showed up.
Similarly, the Wall Street Journal reported that the
American public is not lining up to volunteer as test subjects
in clinical trials testing the anthrax vaccine--even with a
$2,000 cash incentive. [See AHRP Infomail: Anthrax Vaccine

THE WASHINGTON POST
2 States Halt Smallpox Shots
March 28, 2003
By Ceci Connolly
At least two states suspended smallpox immunizations, and
the Pentagon reported its first fatal post-inoculation heart
attack yesterday, even as federal scientists struggled to
figure out whether the vaccine was triggering a series of
cardiac-related problems.
Also yesterday, the government's leading vaccine experts
recommended that the Centers for Disease Control and
Prevention take additional precautions in the beleaguered
program by screening out anyone volunteering for inoculation
with known heart disease or risk factors such as hypertension,
diabetes or high cholesterol.
Altogether, federal health experts are investigating at
least 18 cases of possible cardiac reactions, including three
fatal heart attacks in recently immunized military personnel
and civilian health care workers. But William Winkenwerder
Jr., assistant secretary of defense for health affairs, said
the heart attack death of a 55-year-old National Guardsman was
more likely related to the man's high cholesterol and smoking
than the vaccination.
"That is very noteworthy in this case," Winkenwerder said
in an interview. The evidence at this point, "indicates
smallpox vaccination was not likely to be the cause of his
death." More than 350,000 Defense Department employees have
been inoculated since December.
Although historically the smallpox vaccine has not been
linked to heart attacks or angina, the recent cases have added
to widespread reluctance in the medical community to be
immunized against a disease that has not been seen in three
decades.
In the District, only three of the 11 health department
workers scheduled for inoculation yesterday showed up, said
Michael Richardson, the city's senior deputy director, medical
affairs.
Illinois and New York suspended immunizations entirely, as
did some individual hospitals such as Dartmouth Medical Center
in New Hampshire. Other states, such as Florida, postponed
inoculations until they could update volunteers on new safety
measures relating to heart risks.
At the CDC offices in Atlanta, staffers were fielding
nervous phone calls from people who had been vaccinated and
worried they may be at risk for heart failure, said Dixie
Snyder, associate director for science at CDC.
At the two-month mark, the Bush administration's effort to
immunize millions is stalled, hampered by fears of the vaccine
itself, doubts about the risk of a smallpox attack and the
lack of compensation for people who suffer complications from
the vaccine.
So far, 25,000 people have responded to President Bush's
call for medical personnel to be inoculated, a tiny fraction
of the 450,000 that state officials estimated they would need
to set up mass vaccination clinics in the event of a
bioterrorism attack. The House has rescheduled a vote on a
compensation proposal for Monday, although Democrats complain
the Republican bill falls far short.
"I think it's time to stop the program," said one early
skeptic, Richard Wenzel, chief of internal medicine at the
Virginia Commonwealth University Medical Center in Richmond.
"Now is the time to say let's err on the side of caution until
this is really sorted out."
A safety subcommittee of CDC's Advisory Committee on
Immunization Practices recommended screening out anyone over
age 50 and people under 50 with risk factors for heart
problems, said John Neff, cochair of the smallpox vaccination
safety working group and a physician at Children's Hospital in
Seattle.
"This would provide the maximum degree of safety for the
population," he said. "That is our major concern."
In an emergency two-hour meeting, however, the full
committee stopped short of that position yesterday, in part
because it fears the vaccination program would come to a
standstill.
Eliminating everyone over 50 would make it "infeasible to
develop the numbers we need for preparedness," said Guthrie
Birkhead, a committee member and director of the Center for
Community Health at the New York State Department of Health.
"We are taking extraordinary precautions because of a
theoretical concern."
A few committee members said they preferred to wait for
more data before proceeding with the program.
"You can make the case the risks of this vaccine may be
outweighing its benefits, and at least for the moment, we
should temporarily suspend this program," said Paul Offit,
chief of infectious diseases at Children's Hospital in
Philadelphia. But his proposal for a temporary halt to the
program was quickly dismissed.
CDC spokesmen said they did not know whether officials
would adopt the committee's recommendation or stick to its
decision this week to only weed out people with known heart
disease, such as a previous heart attack.
While experts study the recent cases in hospital workers,
growing evidence suggests that the 10 cases of heart
inflammation in healthy, young Defense Department employees
were related to the vaccinemilitary and CDC experts said. In
every case, the sharp heart pains subsided after patients
received painkillers, and physicians do not expect any
long-term damage.
That discovery raised another challenge for administration
officials trying to refine the civilian vaccination program.
Until now, states have targeted older volunteers because
research has shown the rate of serious reactions is much lower
in people who had been previously vaccinated. But if the
cardiac cases result in fewer older volunteers and more
younger, first-time vaccinees, it is likely the number of
heart inflammation cases is likely to rise, experts said.
Whatever the CDC decides, many physicians, hospitals and
health departments are charting their own course. David
Pearle, a cardiologist at Georgetown University Hospital, said
he would err on the side of caution.
"The worry would be not so much the 35-year-old who smokes,
but perhaps the 55-year-old who smokes and has a family
history," he said, describing the complex set of factors to
consider in deciding who could safely get the vaccine. "If
there is a strong constellation of symptoms, I certainly would
withhold vaccine until we know more."
