Evaluation of a Single Vaccination of One of Three Ascending Dose Levels of a 4-Antigen Staphylococcus Aureus Vaccine (SA4Ag) and a Single Dose Level of a 3-Antigen Staphylococcus Aureus Vaccine (SA3Ag) in Healthy Adults Aged 65 to <86 Years

Summary

This is a Phase 1 and Phase 2 study of a single vaccination with one of three dose levels of a 4-antigen investigational vaccine against Staphylococcus aureus (SA4Ag) and a single dose level of a 3-antigen Staphylococcus aureus vaccine (SA3Ag). 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 65 to \<86 years. In addition, the study aims to assess the effect of the Staphylococcus aureus vaccine on the presence of the Staphylococcus aureus within the nose, throat and perineal skin of healthy adults aged 65 to \<86 years.
