About this trial
This is an interventional prevention trial for Staphylococcus Aureus
Eligibility Criteria
Inclusion Criteria:
- Participant is scheduled to undergo cardiothoracic surgery involving a full median sternotomy (not including cardiac transplantation surgery) within 14 to 60 days after vaccination.
- Female participants of reproductive potential are required to have a negative urine or serum pregnancy test immediately prior to study vaccination and must use an acceptable form of birth control.
Exclusion Criteria:
- Participants had an invasive Staphylococcus aureus infection within the past 3 months prior to study entry.
- A realistic (>50%) possibility that cardiothoracic surgery will be necessary sooner than 10 days after vaccination.
- Participant is planning to undergo cardiac transplantation surgery or sternal debridement to remedy an infection resulting from a prior cardiothoracic surgery.
- Participant has any type of ventricular-assist device in place at the time of study entry.
- Participant has a history of anaphylaxis to any of the vaccine components.
- Participant received V710 vaccine, any other investigational Staphylococcus aureus vaccine, or investigational Staphylococcus aureus antibodies.
- Participant has a temperature of ≥100.4ºF (≥38.0ºC), oral equivalent, within 48 hours prior to study vaccination.
- Participant has impairment of the immune system.
- Participant has a medical condition in which the expected survival is less than 90 days.

Outcomes
Primary Outcome Measures
Number of Participants With Staphylococcus Aureus Bacteremia and/or Deep Sternal Wound Infection
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
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
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
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.
