Approximately half of the UCSB student body opted to receive an unlicensed meningitis vaccine called Bexsero during a free two-week clinic that ended 3/7. More students are expected to receive the shot as several student groups made arrangements to receive the vaccine in the next few weeks, said UCSB spokesperson Andrea Estrada. No additional cases have been reported since four students were diagnosed with the bacterial infection in November. A second shot will be offered in late April.
