Meningococcal disease is an uncommon but very serious infection that occurs when the meningococcal bacteria ‘invades’ the body from the throat or nose. It usually appears as meningitis or sepsis. You can find more information on Meningococcal disease, including what symptoms to look out for on the Immunise Australia website.
Outbreak in Central Australia
An outbreak of Meningococcal W (MenW) occurred in Central Australia from September to December 2017, which affected parts of the Northern Territory (NT), Queensland (QLD), South Australia (SA) and Western Australia (WA).
This outbreak mostly affected young Aboriginal and Torres Strait Islander people in remote Central Australian communities.
In response to this outbreak, four states and territories started meningococcal ACWY vaccination programs for individuals in affected communities. This vaccine protects against meningococcal types A, C, W and Y. These vaccination programs are being run by each state and territory, and are time limited.

Meningococcal disease in Australia
Overall, the national incidence of invasive meningococcal disease (IMD) in Australia is low. From 2003 to 2013, there was a decrease in the number of IMD notifications reported in Australia, following the introduction, in 2003, of the meningococcal C (MenC) vaccine onto the National Immunisation Program (NIP). However, since 2014 notifications of IMD have increased, with numbers during 2017 the highest since 2006. The four most common meningococcal types in Australia are B, C, W and Y. There are vaccines available to protect against these types in Australia.
In response to the rise in the number of MenW cases, six states have started time limited, state-based, meningococcal ACWY vaccination programs which commenced in 2017 for NSW, QLD, TAS, VIC and WA and in 2018 for the ACT. This vaccine will protect against meningococcal types A, C, W and Y. The programs target adolescents aged 15-19 years, with NSW targeting 17-18 year olds.
