The purpose of this study is to assess the safety, reactogenicity, and immunogenicity of 3 different doses of ExPEC10V and to select the optimal dose for further clinical development (Cohort 1). Cohort 2 is aimed to expand the dataset supporting the short- and long-term safety and immunogenicity of the optimal dose of ExPEC10V, selected from the primary analysis results of Cohort 1. Cohort 2 will include participants in stable health with a history of urinary tract infection (UTI) in the past 5 years and will be included in the study to support the plan for late stage development of ExPEC vaccine.
