Trial overview
Official title: Immunogenicity & safety study of GSK Biologicals’ meningococcal vaccine GSK134612 administered in healthy subjects either previously primed with Mencevax™ ACWY or naïve to meningococcal vaccination.
Trial description: In this study, subjects who were vaccinated with a meningococcal polysaccharide vaccine in a previous study (whose objectives & outcome measures are presented in a separate protocol posting with NCT number = 00227422) will be vaccinated with a new vaccine using conjugation technology.These subjects will be compared to subjects vaccinated with the new vaccine, but who were not previously vaccinated with a meningococcal polysaccharide vaccine.
