To date, the available evidence about the safety and efficacy of the anthrax vaccine is resoundingly negative. Three US government anthrax vaccine initiatives represent a reckless deviation from the precautionary principle of medical ethics and fiscal responsibility.

Dear
Secretary Sibelius,
The
Alliance for Human Research Protection (AHRP) is contacting you today with
serious concerns about several issues related to anthrax vaccine:
a) DHHS has submitted a proposal
to conduct a trial to test the anthrax vaccine in children;
http://bioprepwatch.com/news/243663-expert-calls-for-research-into-safety-of-anthrax-vaccine-in-children
b) The FDA has given a fast-track designation
for a new anthrax vaccine that includes a novel adjuvant never before used
in a licensed vaccine the US or, as best we are aware, in any other licensed
vaccine in the world;
http://www.businesswire.com/news/home/20110609006611/en/Emergent-BioSolutions%E2%80%99-Investigational-Anthrax-Vaccine-NuThrax-Granted
c) DHHS has proposed to purchase 44.75 million
additional doses of anthrax vaccine for the National Strategic Stockpile.
http://bioprepwatch.com/news/248321-rep-mike-rogers-praises-biothrax-contract
The
AHRP believes that each of these three initiatives by your Department
constitutes a radical departure from responsible public health policy which
must be grounded in careful risk / benefit analysis, ensuring that the benefits
outweigh the risks for individual citizens as well as for the public. To date,
the available evidence about the safety and efficacy of the anthrax vaccine is
resoundingly negative. Thus, the DHHS anthrax vaccine initiatives represent a reckless
deviation from the precautionary principle of medical ethics and fiscal
responsibility.
We cite the following
reasons:
1. There is little or no threat
-
No evidence has been put forward to show that US citizens are at risk
of anthrax.
-
Anthrax has never been used on any battlefield in world history or in
any terrorist attack by foreigner.
-
The FBI closed the anthrax letters case--which was the only anthrax
attack on US citizens ever-- concluding that a sole US scientist in the
military sent anthrax by mail. So who is
the enemy that threatens us with anthrax?
2. Because
the threat of exposure to anthrax is insignificant, the vaccine is of little to
no value as protection against anthrax.
- The anticipated risks of exposure to the vaccine
for children--who are legally incapable of consenting to research
participation--are substantial, as indicated by points #3 to #9 that
follow.
- Accepted public health practice balances risks and benefits to ensure
that benefits outweigh the risks. In
this case, healthy children, who would derive no benefit from the trial, would
be exposed to a controversial vaccine whose anticipated risks of morbidity and
mortality are substantial. The proposed DHHS pediatric anthrax vaccine trial
would sacrifice children's welfare, much
as canaries sent into the coal mines were sacrificed.
3. There is no scientific evidence that
supports the use of the anthrax vaccine after an exposure.
- Od 30,000 people exposed to anthrax who were offered anthrax vaccine in addition to antibiotics, only 198 accepted. Both groups--those on antibiotics alone, and those on antibiotics and vaccinated--were completely protected from developing anthrax. The addition of the vaccine did not improve outcomes.
- The Anthrax vaccine takes at least 35 days and at least 2-3 doses to stimulate
antibody levels that might provide protection
- The only benefit of vaccinating is to shorten the 60 day duration of antibiotics use, while the risk is death from anthrax if the vaccine does not perform as well as antibiotics. Additionally, there is a risk of developing illnesses due to the anthrax vaccine.
- Even assuming (for argument's sake, but with no substantiating evidence) that the vaccine provides some protection, it will never be as much protection as antibiotics, because even the most effective vaccines are never 100% protective.
- Physicians could not, in good conscience, switch patients from a proven, 100%
effective therapy (antibiotics) to a less effective therapy (vaccine). Some patients switched to vaccine would almost certainly die as a result.
4. The vaccine is not safe.
- After the anthrax attacks, CNN reported that Bill Frist, M.D.,
bioterrorism expert and (then) Senate Majority Leader pointed out:
"The vaccine is a dated vaccine, it's
an old vaccine. There are very real and potentially serious side effects from
the vaccine and anyone who elects to receive the vaccine needs to be made aware
of that. I do not recommend widespread
inoculation for people with the vaccine in the Hart Building. There are too many side effects and if there
is limited chance of exposure the side effects would far outweigh any potential
advantage."
http://archives.cnn.com/2001/US/12/18/anthrax/index.html
- The GAO noted, in a 2007 report:
"Officials from the VHC
[DoD's Vaccine Healthcare Centers] Network and CDC estimate that between 1 and
2 percent of immunized individuals may experience severe adverse events, which
could result in disability or death."
http://www.gao.gov/new.items/d07787r.pdf
- The CDC conducted a Congressionally-mandated clinical trial of anthrax
vaccine in 1,564 US volunteer subjects between 2002 and 2007. This is the largest prospective, randomized,
controlled trial on anthrax vaccine to have ever been done. There were 229 reports of serious adverse
events in these subjects that were submitted to the Vaccine Adverse Event
Reporting System (VAERS) between 2002 and 2007. They were discussed in
conference presentations but no report of the completed trial has ever been published.
- CDC's failure to publish the completed trial data and analysis raises
serious concerns about the safety of the vaccine, and the credibility of CDC pronouncements. The public has virtually no verifiable information
about the nature of the adverse events in the CDC trial and how they may be
related to vaccination.
- It is important
to note that in 2002, the FDA required a revision of the AVA product label to
include approximately 40 serious adverse events. As the product label for AVA
now reads, "Approximately 6% of the reported events were listed as
serious. Serious adverse events include those that result in death,
hospitalization, permanent disability or are life-threatening."
Further,
the FDA raised the rate of systemic reactions by up to 175 times over what had
been listed on the previous 1999 product label, from 0.2% to 5-35%.
5. Under US law, clinical trials in children
must not entail more than minimal risk, if a child does not have a condition
that would benefit from the intervention being studied (45 CFR 46, subpart D).
- There is one rarely used exception (45 CFR 46.407) for "not
otherwise approvable" research in children, which requires that:
"the
research presents a reasonable opportunity to further the understanding, prevention,
or alleviation of a serious problem affecting the health or welfare of
children."
- Inasmuch as there is absolutely NO EVIDENCE to support a claim that
anthrax poses "a serious problem affecting the health or welfare of
children," and the anthrax vaccine provides no prospect of direct benefit
for children, what ethical principles can possibly justify exposing children--much like canaries in the
mines--to the serious risks involved in an anthrax vaccine trial?
- AHRP asserts that the proposed pediatric vaccine trial is unethical and
legally not approvable under the law.
6. The
previous DHHS Secretary invoked the PREP Act for anthrax vaccine.
- What efforts has DHHS made to determine which injuries are caused by
anthrax vaccine?
- How much money is designated for DHHS to compensate injured vaccine
recipients?
7. Purchase
of 44.75 million additional doses of anthrax vaccine for over $1,000,000,000 (billion)
is unnecessary, is a waste of taxpayer money, and is entirely unacceptable
given the state of the US economy.
- The
Center for American Progress issued a report in 2010 about anthrax vaccine
procurement by the federal government titled, “Getting Rich on Uncle
Sucker: Should the Federal Government Strengthen
Efforts to Fight Profiteering?” The
report concluded that the vaccine’s manufacturer made excessively high profits
(on the order of 300% or more) and that such profits had the corrosive effect
of “generating large political contributions and heavy duty lobbying.”
http://www.americanprogress.org/issues/2010/10/pdf/unclesucker.pdf
8. Since
there is no good reason to use anthrax vaccine in anyone, there is absolutely no
justification to test it in children, for whom no benefit is expected but who may
incur significant harm.
- The Institute of
Medicine's report "Ethical Conduct of Clinical Research Involving
Children" (2004), reaffirms the duty to protect children from risks
associated with experimental medical research, affirming federally mandated protection
for children: "Meeting the special
ethical and legal standards for protecting infants, children and adolescents
who participate in research demands additional resources and attention beyond
that required for protecting adults...In some cases, the special ethical and
regulatory protections for children may preclude potentially important clinical
studies that would be approved for adult participation."

9. In
order to improve on the current anthrax vaccine, a similar vaccine with an
added novel adjuvant, made by the same manufacturer, has been given fast-track
approval by the FDA.
- The new vaccine is therefore likely to be licensed in 6 months, with
only rudimentary data regarding safety and efficacy, given that only Phase 1b
trials have been conducted so far.
- Novel adjuvants are substances used to boost the strength of a vaccine.
- They are generally believed to induce more autoimmune adverse effects
than a vaccine without a novel adjuvant will do.
- Indeed, FDA’s director of the Office of Vaccines Research and Review,
Norman Baylor, pointed out in Science magazine that novel
adjuvants could increase the supply of vaccine by using less antigen, but may
be more dangerous for the individual.
“…Antigen-sparing strategies benefit populations, not individuals. ’You
have to think about those trade-offs,’" Baylor said.
http://www.sciencemag.org/cgi/content/short/324/5934/1496
- The adjuvant used in the new vaccine is an immunostimulatory
oligodeoxynucleotide compound, CPG 7909.
This is a piece of DNA, which might insert into one’s genes, with
unknown effects.
- This adjuvant has never been used in any licensed vaccines in the US,
and therefore fast-track status is inappropriate and dangerous, since it is an
entirely new class of drug additive, which has never been used outside small
clinical trials.
AHRP asks that you call an
immediate halt to the proposed pediatric anthrax vaccine trial--as it fails to
comply with ethical and legal standards.
We
further ask that you re-examine the justification for spending more than
$1,000,000,000 (billion) of scarce taxpayer funds--desperately needed for
medical treatment-- to purchase additional anthrax vaccine that will likely
never be needed.
We
further ask that FDA not minimize the approval process by fast-tracking a new
anthrax vaccine whose adjuvant components, the FDA acknowledges, "may be
more dangerous for individuals" than the antigen itself.
Finally,
it is imperative that data from the CDC clinical trial be made publicly
available, to facilitate independent review of anthrax vaccine safety and
efficacy data before any new purchase commitments are made.
Sincerely
yours,
Vera
Hassner Sharav, President and Meryl
Nass, MD
