Has meningococcal serogroup A disease been eradicated?

Abstract

Perennial outbreaks of meningococcal disease in the meningitis belt of Africa have been the norm for several decades. These outbreaks are largely unpredictable in size, location, and causative strain, but are caused predominantly by serogroup A.1 In 2010, a serogroup A meningococcal conjugate vaccine (MenAfriVac) was deployed across the region in a mass vaccination campaign with a plan for phased introduction of MenAfriVac into national routine immunisation programmes across the region.2
