Descriptive Information
Brief Title  ICMJE A Trial To Evaluate A Multivalent Pneumococcal Conjugate Vaccine In Healthy Adults 50-85 Years Of Age
Official Title  ICMJE A PHASE 1/2, RANDOMIZED, OBSERVER-BLINDED TRIAL TO EVALUATE THE SAFETY, TOLERABILITY, AND IMMUNOGENICITY OF A MULTIVALENT PNEUMOCOCCAL CONJUGATE VACCINE IN HEALTHY ADULTS 50 THROUGH 85 YEARS OF AGE
Brief Summary

This is a 2-stage, phase 1/2, randomized, active-controlled, observer-blinded study with a 2-arm parallel design in each stage.

In Stage 1 healthy adults 50 to 64 years of age with no history of pneumococcal vaccination will be randomized equally to receive either a single intramuscular dose of multivalent pneumococcal conjugate vaccine or a licensed tetanus, diphtheria, acellular pertussis combination vaccine (Tdap) (control group).

In Stage 2 healthy adults 65 to 85 years of age previously vaccinated with Prevnar 13 >=2 months prior to investigational product administration will be randomized equally to receive either a single intramuscular dose of multivalent pneumococcal conjugate vaccine or the licensed 23-valent pneumococcal polysaccharide vaccine (control group).
