Genomic surveillance and meningococcal group B vaccine coverage estimates after introduction of the vaccine into the national immunisation programme in the UK

In September, 2015, the meningococcal group B vaccine (Bexsero, GlaxoSmithKline) was introduced into the UK childhood immunisation schedule. Prelicensure coverage estimates used Meningococcal Antigen Typing System (MATS) to determine phenotype and function of circulating meningococci. Using whole-genome sequencing, we aimed to perform rapid, scalable, high-resolution
