Meningococcal
Vaccines
What
you need to know:
1.
What is meningococcal disease?
Meningococcal
disease is a serious illness, caused by a Neisseria menigitidis.
Meningitis
is an infection of fluid surrounding the brain and the spinal cord.
Meningococcal disease also causes blood infections.
Complications
of meningitis are loss of hearing, problems with the nervous systems,
mental retardation, seizures or strokes.
Anyone
can get meningococcal disease. But it is most common in infants
less than one year of age and people with certain medical conditions,
such as lack of a spleen.
About
1 out of every ten people who get the disease dies from it, and
many others are affected for life. This is why preventing the disease
through use of meningococcal vaccine is important for people at
highest risk.
2.
Meningococcal vaccine
Meningococcal
Polysacharide Vaccine against serogroups A and C is available in
the Philippines.
Meningococcal
polysacchride vaccine against 4 types of meningococcal diseases
(seroroups A,C,Y,W-135) is available in the U.S.
3.
Who should get meningococcal vaccine and when?
Meningococcal
vaccine is not routinely recommended in the Philippines.
Meningococcal
vaccine is recommended for other people at increased risk for meningococcal
disease:
Microbiologists
who are routinely exposed to meningococcal bacteria.
Military recruits.
Anyone traveling
to, or living in, a part of the world where meningococcal disease
is common, such as parts of Africa.
Anyone who has
a damaged spleen, or whose spleen has been removed.
Anyone who has
terminal complement component deficiency (an immune system disorder).
People who might
have been exposed to meningitis during an outbreak.
How Many Doses?
Adults
at risk should get 1 dose. Sometimes an additional dose is recommended
for people who remain at high risk.
4.
Some people should not get meningococcal vaccine or should wait.
Anyone
who has ever had a severe (life-threatening) allergic reaction to
a previous dose of either meningococcal vaccine should not get another
dose.
Anyone who has a severe (life threatening) allergy
to any vaccine component should not get the vaccine. Tell your doctor
if you have any severe allergies.
Anyone who is moderately or severely ill at the
time the shot is scheduled should probably wait until they recover.
Safety
in pregnant women has not yet been established. It should be used
only if clearly needed.
5.
What are the risks from meningococcal vaccine?
The
risk of meningococcal vaccine causing serious harm, or death, is
extremely small.
Mild problems
Up to about
half of people who get meningococcal vaccines have mild side effects,
such as redness or pain where the shot was given.
A small percentage
of people who receive the vaccine develop a fever.
Severe problems
Serious
allergic reactions, within a few minutes to a few hours of the shot,
are very rare.
6.
What if there is a moderate or severe reaction?
What
should I look for?
Any unusual condition, such as a high fever or behavior
changes. Signs of a serious allergic reaction can include difficulty
breathing, hoarseness or wheezing, hives, paleness, weakness, a
fast heart beat or dizziness.
What
should I do?
Call a doctor, or get the person to a doctor right
away.
Tell
your doctor what happened, the date and time it happened, and when
the vaccination was given.
7.
How can I learn more?
Ask
your doctor or nurse. They can give you the vaccine package insert
or suggest other sources of information.
