A Study to Evaluate the Safety, Tolerability, and Immunogenicity of V114 Followed by PNEUMOVAX™23 in Healthy Adults 50 Years of Age or Older (V114-016/PNEU-PATH)
Purpose
This study is designed 1) to evaluate the safety, tolerability, and immunogenicity of V114 and Prevnar 13™, 2) to describe the safety of sequential administration of V114 or Prevnar 13™ followed by PNEUMOVAX™23, and 3) to evaluate the immune responses to the 15 serotypes contained in V114 when PNEUMOVAX™23 is given approximately 12 months after receipt of either V114 or Prevnar 13™ in healthy adults 50 years of age or older. There was no formal hypothesis testing.
