A Multicenter, Double-Blind Study of the Safety, Tolerability, and Immunogenicity of V114 Compared to Prevnar 13™ in Healthy Pneumococcal Vaccine-Naïve Adults 50 Years of Age or Older

The purpose of this study is to assess the safety, tolerability, and immunogenicity of a single dose of different formulations of V114 (V114-A and V114-B) and Prevnar 13® (pneumococcal 13-valent conjugate vaccine) in adult participants

≥50 years of age in good health.

• Good health; any underlying chronic illness must be documented to be in stable condition
• Highly unlikely to conceive through 6 weeks after administration of the study vaccine

Exclusion Criteria:

• Known or suspected impairment of immune function
• Received systemic corticosteroids for >=14 consecutive days and has not completed treatment <=30 days prior to study entry, or received systemic corticosteroids exceeding physiologic replacement doses within 14 days prior to study vaccination
• Coagulation disorder contraindicating intramuscular vaccination
• Receives immunosuppressive therapy, including chemotherapeutic agents used to treat cancer or other conditions, and treatments associated with organ or bone marrow transplantation, or autoimmune disease
• Received a blood transfusion or blood products, including immunoglobulins within the 6 months before receipt of study vaccine or is scheduled to receive a blood transfusion or blood product within 30 days of receipt of study vaccine. Autologous blood transfusions are not considered an exclusion criterion.
• Participated in another clinical study of an investigational product within 2 months before the beginning of or any time during the duration of the current clinical study
• Breast feeding
• User of recreational or illicit drugs or has had a recent history (within the last year) of drug or alcohol abuse or dependence
