Meningococcal disease is caused by the bacteria Neisseria meningitidis. There are 13 known sub-types (A, B, C, W and Y). In 2016, the main serotypes causing disease in Australia are B and W with variations noted by state. Importantly, they are both potentially vaccine preventable.
We have recently added a resource page for Meningococcal disease and vaccines to provide further information.
