THE FLU AND THE FLU VACCINE
What is the flu? Influenza is a respiratory infection that
produces fever, chills, sore throat, muscle aches, and cough that
lasts a week or more. The flu can be deadly for the elderly and
those with compromised immune systems or who are suffering from
diabetes, kidney dysfunction and heart disease. Each year about
20,000 Americans, mostly in these high risk groups, reportedly
die from flu complications such as pneumonia.
What is the flu vaccine? The flu vaccine is prepared from the
fluids of chick embryos inoculated with a specific type(s) of
influenza virus. The strains of flu virus in the vaccine are inactivated
with formaldehyde and preserved with thimerosal, which is a mercury
derivative.
Every year, federal health agency officials try to guess which
three flu strains are most likely to be prevalent in the U.S.
the following year to determine which strains will be included
in next year's flu vaccine. If they guess right, the vaccine is
thought to be 70 to 80 percent effective in temporarily preventing
the flu of the season in healthy persons less than 65 years old
(the efficacy rate drops to 30 to 40% in those over 65 years old
but the vaccine is thought to be 50 to 60% effective in preventing
hospitalization and pneumonia and 80% effective in preventing
death from the flu in the over 65 age group). However, sometimes
health officials do not correctly predict which flu strains will
be most prevalent and the vaccine's effectiveness is much lower
for that year.
Does the flu vaccine protect against all throat, respiratory,
gastrointestinal and ear infections? The flu vaccine only protects
against the three specific viral strains which are included in
any given year's flu vaccine. Throat, respiratory, gastrointestinal
and ear infections caused by bacteria or other kinds of viruses
are not prevented by getting an annual flu shot.
Why do doctors say I have to get a flu vaccine every year?
Like all vaccines, the flu vaccine only gives a temporary immunity
to the virus strains or closely related virus strains contained
in the vaccine. The only way to get natural and permanent immunity
to a strain of flu is to recover naturally from the flu. Natural
immunity to a particular strain of flu can be protective if that
strain or closely related strains come around again in the future.
However, because the vaccine only provides a 70 to 80 percent
chance of temporary immunity to selected strains and those strains
may or may not be prevalent each year, doctors say you have to
get a flu shot every year.
Are there reactions to the flu vaccine? The most common reactions,
which begin with 12 hours of vaccination and can last several
days are: fever, fatigue, painful joints and headache. The most
serious reaction that has been associated with flu vaccine is
Guillain-Barre Syndrome (GBS) which occurs most often within two
to four weeks of vaccination. GBS is an immune mediated nerve
disorder characterized by muscle weakness, unsteady gait, numbness,
tingling, pain and sometimes paralysis of one or more limbs or
the face. Recovery lasts several months and can include residual
disability. Less than 5 percent of GBS cases end in death.
What are contraindications to the flu vaccine? Among high risk
factors listed by the CDC and the vaccine manufacturers are anyone
who: (1) is sick with a fever; (2) has an impaired immune system;
(2) has an egg allergy; (3) has a mercury allergy; (4) has a history
of Guillain-Barre syndrome. In years past, pregnancy was also
a contraindication to flu vaccine but, today, the Advisory Committee
on Immunization Practices (ACIP) of the Centers for Disease Control
(CDC) recommends flu vaccine for women more than 14 weeks pregnant.
The package inserts published by the flu vaccine manufacturers
state that "Animal reproduction studies have not been conducted
with influenza virus vaccine. It is also not known whether influenza
virus vaccine can cause fetal harm when administered to a pregnant
woman.Although animal reproductive studies have not been conducted,
the prescribing health care provider should be aware of the recommendations
of the Advisory Committee on Immunization Practices The ACIP states
that if used during pregnancy, administration of influenza virus
vaccine after 14 weeks of gestation may be preferable to avoid
coincidental association of the vaccine with early pregnancy loss."
Is Flu Vaccine Recommended for Children? The flu vaccine has
never been recommended for healthy children. However, in the past
few years there have been indications that health officials are
soon going to recommend flu vaccine for all children. A nasal
flu vaccine is scheduled to be on the market in late 2000 and
publicity promoting this vaccine has centered on its potential
use in children.
The current injectable flu vaccine contains mercury as a preservative.
In the summer of 1999, the FDA, CDC and EPA directed the vaccine
manufacturers to remove mercury as a preservative in childhood
vaccines. Mercury is a known neuro-toxin and American babies under
six months of age are currently exposed to mercury in childhood
vaccines that exceed EPA safety standards.
One consideration with the mass use of flu vaccine in healthy
children is the removal of natural antibodies to flu which are
obtained from natural infection. The question of whether it is
better for healthy children, who rarely suffer complications from
flu, to get the flu and develop permanent immunity to that flu
strain or it is better for children to get vaccinated every year
to try to suppress all flu infection in early childhood is a question
that has yet to be adequately answered by medical science.
What should I do? Become educated about the flu and its
benefits and risks and the vaccine and its benefits and risks
and make an informed decision after consulting multiple sources
of information and discussing your questions with one or more
health professionals.
