Meningococcal vaccines for Australians: Information for providers, NCIRS factsheet
Meningococcal disease is a rare but serious infection caused by the bacterium Neisseria meningitidis. There are 13 serogroups; those that most commonly cause disease are A, B, C, W and Y.
The incidence of invasive meningococcal disease (IMD) fluctuates naturally over time. The national notification rate declined from 2002 to 2013, but has increased since 2014. Serogroup B disease has been dominant until recently, but has been naturally declining even in the absence of widespread vaccination against this serogroup. There has been a recent increase in serogroup W disease since 2013; this is now the main serogroup causing meningococcal disease (44.5% of cases with identified serogroup) in Australia in 2016.
