The respiratory tract harbours microorganisms of the normal host microbiota which are also capable of causing invasive disease. Among these, Neisseria meningitidis a commensal bacterium of the oropharynx can cause meningitis, a disease with epidemic potential. The oral microbiome plays a crucial role in maintaining respiratory health.

Invasive meningococcal diseases (IMD) caused by Neisseria meningitidis are generally rare. They affect mostly selected age categories and risk groups of patients (in terms of age, comorbidities, or applied therapy), and the immune system and its defects may play an important modifying role. Meningococcal infections could be the first and only clinical sign of unrecognised immunodeficiency.

Methods: In this phase 3 study (NCT04707391), healthy participants aged 15-25 years, who had received MenACWY vaccination ≥4 years previously, were randomized (1:1) to receive two MenABCWY doses six months apart or one MenACWY-CRM dose. Primary objectives were to demonstrate the non-inferiority of MenABCWY 1 month post-vaccination versus MenACWY-CRM, with a lower limit of 2-sided 95% confidence interval above -10% for group differences in 4-fold rise in human serum bactericidal antibody (hSBA) titers against serogroups ACWY, and to evaluate reactogenicity and safety.

Background: Invasive meningococcal disease (IMD) is a life-threatening disease, primarily affecting infants and children. Argentina introduced routine meningococcal vaccination in infants and adolescents in 2017, with MenACWY vaccination targeting serogroups A, C, W, and Y (current National Immunization Program [cNIP]). Serogroup B, more prevalent since 2015, became predominant in children.
