Efectividad de la vacuna VA-MENGOC-BC® contra cepas heterólogas de meningococo B / Effectiveness of VA-MENGOC-BC® vaccine against heterologous strains of meningococcus B

RESUMEN

La efectividad de las vacunas de vesículas de membrana externa de Neisseria meningitidis serogrupo B ha sido cuestionada por algunos investigadores, limitándola a la cepa vacunal. VA-MENGOC-BC® es una vacuna antimeningocócica basada en dicha tecnología. Presentamos un metaanálisis de estudios realizados en diferentes contextos epidemiológicos, evaluando su efectividad contra cepas heterólogas de meningococo B en varios grupos de edades. Se demuestra que la vacuna es efectiva contra cepas homólogas, heterólogas y de diferentes complejos clonales(AU)

ABSTRACT

Vaccines based on outer membrane vesicles of Neisseria meningitidis serogroup B strains have been questioned by some researchers, who limit its effectiveness to the vaccine strain. VA-MENGOC-BC® is a meningococcal vaccine based on this technology. A meta-analysis of independent studies in different epidemiological contexts is used to assess the clinical effectiveness of the vaccine against heterologous serogroup B strains in several age groups. In this paper we provide evidence supporting its effectiveness against homologous and heterologous strains from different clonal complexe(AU)
