The meningococcal vaccines protect against meningococcal disease, a serious infection
that can lead to bacterial meningitis
and other serious infections.
Two kinds of meningococcal (meh-nin-guh-KOK-uhl) vaccines are currently given to
kids in the United States:
The meningococcal conjugate vaccine protects against four types
of meningococcal bacteria (called types A, C, W, and Y). It is recommended for all
The meningococcal B vaccine (MenB) protects against a fifth type
of meningococcal bacterium (called type B). It is fairly new and not yet recommended
as a routine vaccination for healthy people, but might be given to some kids and teens
(ages 16 through 23) who are at increased risk for meningococcal disease.
When Are Meningococcal Vaccines Given?
Vaccination with meningococcal conjugate vaccine is recommended:
when kids are 11 or 12 years old, with a booster given at age 16
for teens 13–18 years old who haven't been previously vaccinated
Those who have their first dose between the ages of 13–15 should get a booster
dose between the ages of 16–18. Teens who get their first dose after age 16
(for example, previously unvaccinated college freshmen who will be living in dorms
or those entering the military) won't need a booster dose.
A full series of the meningococcal conjugate vaccines should be given to kids and
teens who are at higher risk for meningococcal disease (even if younger than 11 years
old), including those who:
live in or travel to countries where the disease is common
are present during an outbreak of the disease
have certain immune disorders. If the immune disorders are chronic, these kids
also need a booster dose a few years later, depending on the age at which the first
dose is given.
The sequence and dosage will depend on the child's age, medical condition, and
vaccine brand. Some types of meningococcal vaccines can be given as early as 8 weeks
Kids 10 years and older with these risk factors also should get a full series of
the MenB vaccine.
For those without risk factors, the decision to receive the MenB vaccine should
be made together by the teen, his or her parents, and the doctor. For these kids,
the preferred age range is 16–18 years. Two or three doses are needed depending
on the brand.
Why Are Meningococcal Vaccines Recommended?
Meningococcal disease is caused by a type of bacteria. It can lead to an infection
of the bloodstream or meningitis, or both, and can be life-threatening if not quickly
treated. The meningococcal conjugate vaccine is very effective at protecting against
four strains of the bacteria, while the MenB vaccine protects against a fifth strain.
What Are the Possible Side Effects of Meningococcal Vaccines?
Some of the most common side effects are swelling, redness, and pain at the site
of the injection, along with headache, fever, or tiredness. Severe problems, such
as allergic reactions, are rare.
When to Delay or Avoid Immunization
The vaccine is not recommended if:
your child is currently sick, although simple colds or other minor illnesses should
not prevent immunization
your child has had a severe allergic reaction to a previous dose of meningococcal
vaccine, to the DTaP vaccine,
or to latex
What Happens After the Immunization?
Your child might have a fever, soreness, and some swelling and redness in the area
where the shot was given. Check with your doctor to see if you can give either acetaminophen or ibuprofen
for pain or fever and to find out the appropriate dose.
A warm, damp cloth or a heating pad on the injection site may help reduce soreness,
as can moving or using the arm.
When Should I Call the Doctor?
Call if you aren't sure if the vaccine should be postponed or avoided.
Call if there are problems after the immunization.
