INFORMED CONSENT ADVOCATE SAYS GOVERNMENT AND
INDUSTRY SHOULD RELEASE FLU VACCINE EFFECTIVENESS DATA
Washington, D.C. - A leading vaccine safety and informed consent advocate is
calling on federal health officials and flu vaccine makers to be honest with
the American people about the effectiveness of this year's flu vaccine.
"Public health officials knew last spring that it was highly likely that the
A/Panama strain in the current vaccine was not going to protect against the
mutated, more dangerous A/Fujian strain of flu. If there is solid new
evidence that the vaccine is protective against Fujian, then it should be
released. If there is no such evidence, then it is not right to lead people
to believe that if they get vaccinated now, they will be protected against
it," said Barbara Loe Fisher, president, National Vaccine Information Center
(NVIC).
Federal officials were prevented from replacing the A/Panama strain with the
Fujian strain emerging out of Asia and being detected in Europe and the U.S.
last spring because scientists in labs around the world were unable to
isolate and grow the virus in a way that would allow vaccine production.
Transcripts from the February 20 and March 18, 2003 meetings of the FDA
Vaccines and Related Biological Products Advisory Committee (VRBPAC) reveal
that health officials around the world knew the genetically mutated Fujian
strain was associated with significant morbidity and mortality and that last
year's vaccine showed little protection against it.
Fisher, who was the consumer voting member of the FDA Advisory Committee,
abstained from the strain selection vote on March 18, saying "I feel
uncomfortable voting for inclusion of an A/Panama-like virus, when what may
really be needed is an A/Fujian-like virus. So I am going to abstain and
urge that the public be informed that next year's flu vaccine may not be
protective against an emerging strain."
The National Vaccine Information Center is a non-profit, educational
organization founded in 1982 by parents whose children were injured or died
from reactions to the DPT vaccine. Dedicated to preventing vaccine injuries
and deaths through public education, NVIC also advocates for the inclusion
of informed consent protections in national vaccine policies and laws. "This
is a matter of the public's right to have full and truthful information
about the benefits and risks of a particular vaccine in order for us to make
an informed choice. Although there were technological limitations with
making the switch this year to the new emerging strain, it does not serve
either public health officials, industry or the public to not be honest
about what the current vaccine can and can't do. At the end of the day, it
is a matter of respecting the public trust," she said.
Every year, health officials at the World Health Organization (WHO) and the
U.S. Department of Health and Human Services (DHHS) gather information about
influenza activity around the world in order to try to make an educated
guess about which three flu strains to include in the current year's flu
vaccine. This year, in addition to the inactivated (killed) flu vaccine
which is injected, a new live virus nasal flu vaccine is available in the
U.S. Both the inactivated and live virus vaccines contain the same three flu
strains. Neither flu vaccine this year contains the mutated Fujian strain
that is causing the most severe flu in the U.S. this season.
The new live virus vaccine (FLUMIST), which is squirted up the nose, was
licensed by the FDA in June 2003 for use in healthy individuals between the
ages of five and 50. It is not recommended for pregnant women or those with
asthma, chronic lung or heart disease; chronic underlying medical conditions
such as diabetes or kidney disorders; immune suppression or immune system
problems; children or adolescents receiving aspirin therapy, anyone allergic
to eggs; or those with a history of Guillain Barre syndrome. It should not
be given simultaneously with other vaccines.
FLUMIST's vaccine live virus is shed after vaccination so the vaccinated are
advised to avoid close contact with immune compromised individuals for at
least 21 days. Some hospital personnel are asking those recently vaccinated
with FLUMIST to avoid visiting patients in hospitals to prevent the risk of
transmitting the vaccine strain virus to sick patients. The most common
reactions to the live flu vaccine are similar to the flu: runny nose, nasal
congestion, cough, sore throat, headache, muscle aches, fever, chills, and
weakness.
The killed flu vaccine, which is injected, has historically been used in
individuals over 60 years old who are at high risk for dying or becoming
seriously ill during a bout with the flu. However, in recent years, the CDC
has been asking all age groups to get an annual flu shot and now recommends
that all healthy children older than 6 months of age get an annual flu shot.
Contraindications for the killed flu vaccine are: fever, an impaired immune
system, egg allergy, mercury allergy or a history of Guillain Barre
syndrome. In the past, pregnancy was a contraindication but now the CDC
recommends flu vaccine for women more than 14 weeks pregnant. However this
recommendation is controversial since most flu vaccines still contain the
mercury preservative, Thimerosal, and mercury has been associated with brain
damage and developmental delays in fetuses whose mothers were exposed to
high levels of mercury during pregnancy.
The most common reactions to killed flu vaccine are fever, fatigue, painful
joints and headache. The most serious reported reaction, which usually
occurs within two weeks of vaccination, is Guillain Barre syndrome, an
immune mediated nerve disorder characterized by muscle weakness, numbness,
pain and paralysis.
Flu vaccine only protects against the three specific viruses which are
included in any given year's flu vaccine formulation and does not protect
against throat, respiratory, gastrointestinal and ear infections caused by
bacteria and other kinds of viruses. When the match between the vaccine and
circulating viruses is close, the flu vaccine is thought to provide a 70 to
90 percent chance of temporary immunity to selected strains in healthy
persons less than 65 years old. For those over 65 years old, the efficacy
rate drops to 30 to 40 percent, although it is considered to be 50 to 60
percent effective in preventing hospitalization or pneumonia and 80 percent
effective in preventing death from flu caused by the covered strains.

strains, go to NVIC's website at www.NVIC.org/Diseases/Influenza.htm.
