Abstract
Invasive meningococcal disease incidence in England declined from 1.93/100,000 persons (1,016 cases) in 2010–11 to 0.95/100,000 (530 cases) in 2018–19 and 0.74/100,000 in 2019–20 (419 cases).

Highlights
Neisseria meningitidis is a major global cause of bacterial meningitis and septicemia (1)
We report invasive meningococcal disease (IMD) incidence in England during 2011–2020, including the impact of a national lockdown to control the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
Adolescent MenACWY and infant 4CMenB immunization programs in 2015 led to additional annual declines in IMD incidence, to 0.95 cases /100,000 population (530 cases) in 2018–19
Summary
Neisseria meningitidis is a major global cause of bacterial meningitis and septicemia (1). We report IMD incidence in England during 2011–2020, including the impact of a national lockdown to control the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). IMD incidence was highest, 1.93 cases/100,000 population (1,016 total cases), during the 2010–11 academic year (September–August) and declined to 1.15 cases /100,000 population for 2013–14 (617 cases) before increasing to 1.51 cases /100,000 population (825 cases) in 2015–16 (Figure).
