MATS, meningococcal antigen typing system; gMATS, genetic MATS; 4CMenB, 4-component meningococcal serogroup B vaccine; N, number of tested isolates; CI, coverage interval; LL, lower limit; UL, upper limit; ACT, Australian Capital Territory.
Notes: * Not calculated, due to the small number of strains isolated.
** The age of the patient from whom the sample was collected was only documented for 319 of the total 520 strains.
