Evaluation of a Single Vaccination With One of Three Ascending Dose Levels of a 4-Antigen Staphylococcus Aureus Vaccine (SA4Ag) in Healthy Adults Aged 18 to <65 Years

Summary

This is a first-in-human (Phase 1) and Phase 2 study of a single vaccination with one of three dose levels of an investigational vaccine against Staphylococcus aureus (SA4Ag). The main goal of the study is to determine how safe and well tolerated the vaccine is as well as to describe the immune response elicited by the vaccine in healthy adults aged 18 to \<65 years. In addition, the study aims to assess the effect of the SA4Ag vaccine on the presence of the Staphylococcus aureus on the skin and within the nose, throat and perineum of healthy adults aged 18 to \<65 years.
