Oct. 23, 2007 -- The FDA has expanded the age range for Menactra, a
bacterial meningitis vaccine, to include children aged 2-10.
Meningitis is a serious inflammation of the lining that surrounds the spinal
cord and brain. It can result in death or permanent injury to the brain and
Each year in the U.S, about 2,600 people become ill from bacterial
meningitis. About 10% die from the infection and about 15% suffer brain damage
or limb amputation, according to the FDA.
The FDA first approved Menactra in January 2005 for people aged 11-55.
Previously, Menomune was the only meningococcal vaccine available in the U.S.
for use in children age 2 and older.
Both products are made by Sanofi Pasteur Inc. Both vaccines offer protection
against four groups of Neisseria meningitidis, a bacterium that can
Both vaccines work well and protect about 90% of those who get it, but
Menactra is expected to give better, longer-lasting protection, according to
background information on the CDC's web site.
"Approving Menactra for younger children offers another option for
health care providers and parents. Now there are two vaccines available for
children between 2 and 10 years of age who may be at increased risk of
meningitis," says Jesse Goodman, MD, MPH, in an FDA news release.
Goodman directs the FDA's Center for Biologics Evaluation and Research.
The CDC recommends meningococcal vaccination for children aged 2-10 who are
at increased risk of developing meningococcal disease, such as:
- Children who have had their spleen removed or whose spleen isn't
- Children with a medical condition called terminal complement component
deficiency, which makes it difficult to fight infection.
- Children who expect to travel to areas outside of the U.S. where
meningococcal disease is common.
Vaccination is also used to control outbreaks of bacterial meningitis.
Menactra’s effectiveness was measured in clinical trials that included
people aged 2-55. The vaccine was shown to produce an immune response one month
Menactra's safety was evaluated in eight clinical studies that included some
10,000 patients who received Menactra and more than 5,200 others who received
Menomune. The most common adverse events reported in the studies were pain at
the injection site and irritability. Diarrhea, drowsiness, and lack of appetite
also were common, according to the FDA.
While not observed in these clinical trials, Guillain-Barré syndrome (GBS),
a neurological disorder that causes muscle weakness, was noted as a possible
but unproven risk in some adolescents following immunization with Menactra.
Those cases occur in an estimated one in a million vaccine recipients,
states the FDA. As a precaution, people who have previously been diagnosed with
GBS should not receive Menactra.
The FDA and CDC will continue to monitor Menactra's safety through their
jointly administered Vaccine Adverse Event Reporting System.
