Primary Outcome Measures:
  • Proportion of subjects with a positive response to tetanus toxoid adsorbed vaccine [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Proportion of subjects with a 2-fold increase in tetanus antibody titers, or with tetanus antibody titers ≥ 0.2 IU/mL [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
  • Proportion of subjects with positive responses against an individual anti pneumococcal antibody serotype [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
  • Proportion of subjects with positive responses against at least 50% of the serotypes (≥ 6/12) [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
  • Levels of anti-tetanus antibody in subjects measured immediately prior to and 4 weeks after a booster vaccine [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
  • Levels of anti pneumococcal antibody to 12 serotypes in subjects measured immediately prior to and 4 weeks after vaccination [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
  • Levels of anti-KLH antibody in subjects measured immediately prior to the first administration of KLH and 4 weeks after the first administration of KLH [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
  • Proportion of subjects who maintain a positive response to Candida albicans [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Proportion of subjects with an ACR 20/50/70 response [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Criteria

Inclusion Criteria:
