(CNN) - The FDA has given special approval for students at the University of California Santa Barbara to get an unlicensed meningitis vaccine after an outbreak of the disease on campus.
Four students were confirmed sick with meningococcal disease. That can cause meningitis or blood infections.
A case on the California campus was so severe that doctors had to remove a student's lower legs.
Swiss drug maker Novartis has approval for the vaccine in Europe, Canada, and Australia, but not the U.S.
The FDA granted approval for the drug's use in the states last December to fight an unrelated outbreak on Princeton's campus.
