Serum bactericidal activity against circulating and reference strains of meningococcal serogroup B in the United States: A review of the strain coverage of meningococcal serogroup B (MenB) vaccines in adolescents and young adults

Résumé fourni par la source

Invasive meningococcal disease (IMD) is rare but associated with high morbidity and mortality. In the United States, the most vulnerable age groups are infants and adolescents/young adults, and the most common type of IMD is caused by serogroup B (MenB). MenB is preventable among adolescents and young adults with the use of two licensed vaccines, MenB-FHbp (Trumenba®, bivalent rLP2086; Pfizer Inc, Collegeville, PA) and MenB-4C (Bexsero®; GSK Vaccines, Srl, Italy). Because the effectiveness of MenB vaccination is dependent on broad vaccine coverage across circulating disease-causing strains, we reviewed the available clinical and real-world evidence regarding breadth of coverage of the two licensed vaccines in adolescents and young adults in the United States. Both vaccines protect against various MenB strains. More controlled data regarding breadth of coverage across MenB strains are available for MenB-FHbp compared with MenB-4C, whereas more observational data regarding US outbreak strain susceptibility are available for MenB-4C.
