A major Australian meningococcal B vaccine trial among teenagers has failed to show any discernable impact on throat carriage of Neisseria meningitidis or herd immunity.

Between 2017 and 2018, almost 35,000 SA high school students participated in the largest meningococcal B herd immunity study to date, supported by the vaccine manufacturer GlaxoSmithKline (GSK).
