title: Meningococcal group B vaccine trial in Norway 1981--1982. Preliminary report of results available November 1982.
abstract: A combined serogroup B capsular polysaccharide and serotype 2a outer membrane complex meningococcal vaccine and a placebo preparation were tested double-blindly in 55 adult, male volunteers. The vaccine gave twofold increased binding antibodies, measured by ELISA, against non-capsular outer membrane antigen in 85 per cent of those vaccinated. Bactericidal antibodies towards a meningococcal serogroup C serotype 2a strain also increased fourfold or more among 85% vaccinated. New acquisition of meningococcal carriage was associated with antibody increase in one person from the placebo group.
