Oct. 4, 2005 -- The FDA, CDC, and vaccine company Sanofi Pasteur are
alerting doctors and patients about a possible side effect of Menactra, a new
Five American teens reportedly developed a serious neurological condition
called Guillain-Barré syndrome after being vaccinated with Menactra, which is
made by Sanofi Pasteur.
Guillain-Barré syndrome often strikes healthy people, either spontaneously
or after certain infections. It typically causes increasing weakness in the
legs and arms that can be severe and require hospitalization.
However, the FDA isn't changing its vaccine recommendations, since it's not
yet known if Menactra caused the reported Guillain-Barré syndrome cases.
"Individuals should continue to follow their doctors'
recommendations," states an FDA news release.
All Patients Recovered or Recovering
All five reported cases occurred in 17- or 18-year-olds living in four
states: New York, Ohio, Pennsylvania, and New Jersey.
The five teens have all reportedly recovered or are recovering. They had
developed weakness or abnormal sensations in their arms or legs between two and
four weeks after getting the Menactra vaccine, says the FDA.
About Menactra & Meningitis
Menactra protects against bacterial meningitis, which strikes about one in
100,000 people per year. Teens and young adults account for almost a third of
bacterial meningitis cases.
The infection can spread among people living in close quarters, such as
college dorms. Kissing an infected person or sharing food can also spread the
Most people recover from bacterial meningitis, but the disease can be
disabling or fatal. Bacterial meningitis kills 10% to 14% of patients and
permanently disables 11% to 19% of survivors, according the FDA.
No Guillain-Barré syndrome cases were seen in prelicensure studies of more
than 7,000 people who had taken Menactra, says the FDA. The CDC also did a
quick check of available health care organization databases and found no
reported cases among 110,000 Menactra recipients.
Vaccination is the most effective way to reduce the risk of death and
permanent disability caused by bacterial meningitis.
In a news release, Sanofi Pasteur pledges to keep working with the FDA and
CDC to thoroughly investigate the reported cases of Guillain-Barré syndrome
