Meningitis B outbreak confirmed at two US universities

  • November 25, 2013
Currently, there are two outbreaks of serogroup B meningitits in the United States; eight cases have been reported from Princeton University and three from the University of California, Santa Barbara, according to releases from each state’s public health department.
An eighth Princeton University student is hospitalized and receiving treatment after she was diagnosed with meningitis on Nov. 21, according to a statement from Princeton University.
Health officials are conducting tests to determine whether this latest case is related to the seven cases of Neisseria meningitidis serogroup B meningitis cases associated with the university since March.
As of Nov. 14, there have been seven cases of confirmed invasive meningococcal disease among six students and one visitor to the campus, according to a Princeton University press release.
Six patients have recovered, and the most recent patient remains hospitalized, according to a statement from the New Jersey Department of Health.
Two of the three cases at the University of California, Santa Barbara have been confirmed as N. meningitidis serogroup B meningitis, according to a press release. Laboratory testing is being performed on the third. The first two cases are recovering, and the third is currently receiving medical care.
In response to the meningococcal serogroup B outbreak that began at Princeton in March, university officials said they expect to make the first of a serogroup B meningococcal two-dose series vaccine (4CMenB; Bexsero, Novartis) currently approved for use outside the United States available in early December. The second dose should be available in February, according to the statement.
“The CDC and FDA have determined that the unique pattern of the disease in this Princeton outbreak — the high rate of cases that have occurred and over the long period of time they have occurred in — warrant expanding access to a group B vaccine for that high-risk population,” Amanda Cohn, MD, a medical officer with the CDC, said during a press briefing. “Each outbreak situation is unique and requires rigorous assessment before use of this vaccine can be considered. With that said, we’re open to recommending this vaccine during other outbreaks of serogroup B meningococcal disease, and we’ll follow each outbreak very closely and make decisions about requesting use of vaccines for additional outbreaks when needed.”
The university said it will cover the cost of the vaccine for all students who receive it. Students younger than 18 years will need a signed consent form from their parent or guardian before receiving the vaccine.
The CDC is expected to recommend that all Princeton University undergraduate students receive the vaccine. This includes students who live in dormitories and off campus, and graduate students who live in dormitories, as well as members of the university community who have functional and anatomic asplenia (including sickle cell disease) and late complement component deficiencies.
The vaccine would be made available only to these groups, and it would not be administered anywhere else.
Meningococcal vaccines licensed in the United States include four of the five most common serogroups: A, C, Y and W-135. However, there is currently no vaccine licensed in the United States that protects against serogroup B.
