Currently, 1300-1500 cases of meningococcal infections are reported each year in England and Wales, although the true burden of disease may be 30%-40% higher due to undemotification [1]. Serogroup C disease accounts for about one-third of these infections, with children 2 p,g/mL 6/54 (II) 52/52 (100) 56/56 (100) 56/56 (100) 25/48 (52)
