An Evaluation Of Three Dose Levels Of 3-Antigen Staphylococcus Aureus Vaccine (SA3Ag) In Healthy Adults

"In stage 1, each subject will receive 1 injection (0.5 mL) of one of the following doses:~Low dose level 10 μg of CP5 and CP8 and 20 μg of rClfAm Mid-dose level 30 μg of CP5 and CP8 and 60 μg of rClfAm High dose level 100 μg of CP5 and CP8 and 200 μg of rClfAm~In stage 2 the subject will receive 0.5 mL IM of the same dose level he/she received in stage 1."

Blood for immunogenicity will be taken at timepoints throughout stage 1 and stage 2. Blood for hematology will be done in a select subset of subjects in stage 1.

Colonization swabs will be taken at timepoints throughout stage 1 and stage 2.

"In stage 1, each subject will receive 1 injection (0.5 mL) of one of the following doses:~Low dose level 10 μg of CP5 and CP8 and 20 μg of rClfAm Mid-dose level 30 μg of CP5 and CP8 and 60 μg of rClfAm High dose level 100 μg of CP5 and CP8 and 200 μg of rClfAm~In stage 2 the subject will receive one injection of 0.5 mL IM of the placebo."

Blood for immunogenicity will be taken at timepoints throughout stage 1 and stage 2. Blood for hematology will be done in a select subset of subjects in stage 1.

Colonization swabs will be taken at timepoints throughout stage 1 and stage 2.

In both stage 1 and stage 2, recipients will receive one injection (0.5 mL) IM of 150 mM (isotonic) NaCl for a total of 2 injections throughout the study.
