PRIMARY outcome

Timeframe: Baseline and Day 14 postvaccination

Population: The per-protocol analysis excluded patients who had missing baseline and/or postvaccination (Day 14) serology data and patients who developed a S. aureus infection during the 14 days postvaccination.

Immunoglobulin G (IgG) antibodies were measured by a LUMINEX(TM) assay.

PRIMARY outcome

Timeframe: Baseline and Day 14 postvaccination

Population: The per-protocol analysis excluded patients who had missing baseline and/or postvaccination (Day 14) serology data and patients who developed a S. aureus infection during the 14 days postvaccination.

Immunoglobulin G (IgG) antibodies were measured by a LUMINEX(TM) assay. The GMFR is the ratio of the antibody concentration at Day 14 to the antibody concentration at baseline.

PRIMARY outcome

Timeframe: Up to Day 360 postvaccination

Population: Any subject who received clinical material and had at least 1 day of safety follow-up was included in the safety summary.

Investigators were instructed to determine the seriousness and causality (relatedness to test vaccine) of each AE based on criteria defined in the protocol: A serious adverse event (SAE) is any AE that: * results in death, * is life threatening, * results in a persistent or significant disability/incapacity, * results in or prolongs an existing inpatient hospitalization, * is a congenital anomaly/birth defect, * is a cancer, * is an overdose, * or is another important medical event that may require medical or surgical intervention to prevent one of the outcomes listed above.
