A new meningococcal B vaccine for adolescents and adults: characteristics and methods of use

The invasive disease from Neisseria meningitidis is one of the leading causes of death for meningitis and sepsis at all ages. The highest incidence of cases occurs at paediatric and adolescent age, but no age of life is considered protected from this infection and disease. Prevention against the five main serogroups is possible using the combined conjugated polysaccharide vaccine against the ACWY (anti-MenACWY) serogroups and the meningococcal B (anti-MenB) protein vaccines. Trumenba® vaccine, approved by the EMA (European Medicine Agency) for use in individuals aged ≥ 10 years, protects against serogroup B invasive disease. This bivalent, recombinant vaccine is able, when given with a 0-6 month schedule, to induce a protective response in adolescents and young adults, comparable with a 3-doses schedule. For this reason, the Trumenba® vaccine should be used routinely with the 2-dose schedule (0-6 months). The 3-doses use could be considered in particular situations, like an occurring epidemic or particular individual risk factors such as asplenia or complement deficit, but is not needed for underlying conditions like diabetes or heart diseases.
