There were 290 cases of invasive meningococcal disease (IMD) recorded in England in the first six months of this year, according to figures from the national Public Health England (PHE) Meningococcal Reference Unit. The figure is a significant reduction on the 462 cases that were recorded in the same period last year. This relatively low number of confirmed cases in 2019 was observed across all capsular groups.

Capsular group B (MenB) accounting for 55 per cent of all cases between April and June 2019, followed by MenW (27%), MenY (10%) and MenC (8%). There were 66 MenB cases confirmed in the six-month period, 34 per cent lower than the equivalent period in 2018 (100 cases) and similarly MenW cases were 30 per cent lower (32 cases). In quarter 2, the number of confirmed MenC cases was 40 per cent lower in 2019 than in the equivalent period in 2018, while the number of MenY cases was similar in Q2 of 2019 and 2018.

MenB was responsible for the majority of IMD cases in children aged less than five years of age (69%), followed by MenW (19%). MenB accounted for more than half of cases in individuals aged between five and 64 years (60%) and 34 per cent of cases in adults aged 65 years or more.

Estimated vaccine coverage for infant MenB immunisation across England was 92.2 per cent for two doses at 12 months of age and 88.8 per cent by 24 months of age.
