Purpose
This study will assess the efficacy of a single dose of V710 vaccine to prevent serious Staphylococcus aureus infections following elective cardiothoracic surgery. The study will also evaluate the immune response and general safety of the V710 vaccine.

Primary Outcome Measures:
- Number of Participants With Staphylococcus Aureus Bacteremia and/or Deep Sternal Wound Infection [ Time Frame: Up to 90 days after surgery ]Diagnosis of the Staphylococcus aureus infections employed standardized definitions adapted from the Centers for Disease Control (CDC) Guidelines for Nosocomial infections (Garner JS, Jarvis WS, Emori TG, et al. CDC definitions for nosocomial infections. APIC Infect Control App Epidemiol 1996;A1-20). Bacteremia was defined as ≥1 positive blood culture for S. aureus regardless of the presence of clinical symptoms. A Staphylococcus aureus deep sternal wound infection included mediastinitis or a deep incisional surgical-site infection involving the sternal wound.
- Incidence Rate of Vaccine-related Serious Adverse Experiences [ Time Frame: Up to 360 days after surgery ]Vaccine-related adverse experiences were those deemed by the investigator to be possibly, probably, or definitely vaccine related. A serious adverse experience was any adverse experience occurring at any dose that 1) resulted in death, 2) was life threatening, 3) resulted in a persistent or significant disability/incapacity, 4) resulted in or prolonged an existing inpatient hospitalization, 5) was a congenital anomaly/birth defect, 6) was a cancer, 7) was an overdose, or 8) jeopardized the participant and required medical or surgical intervention.
Secondary Outcome Measures:
- Number of Participants With Invasive Staphylococcus Aureus Infection [ Time Frame: Up to 90 days after surgery ]Diagnosis of the Staphylococcus aureus infections employed standardized definitions adapted from the CDC Guidelines for Nosocomial infections. An invasive Staphylococcus infection included bacteremia, deep sternal wound infection, deep-tissue organ/space infection at another surgical site, or any other deep-tissue infection.
- Number of Participants With Surgical-site Staphylococcus Aureus Infection [ Time Frame: Up to 90 days after surgery ]Diagnosis of the Staphylococcus aureus infections employed standardized definitions adapted from the CDC Guidelines for Nosocomial infections. A Staphylococcus infection surgical-site infection included any superficial incisional, deep incisional, or organ/space infection at the sternal site, the vascular harvest (donor) site, or any other site at which the surgery was performed.
