Clostridium Difficile Clinical Trial

Official title:
A Phase 1, Placebo-controlled, Randomized, Observer-blinded Trial To Evaluate The Safety, Tolerability, And Immunogenicity Of An Adjuvanted Clostridium Difficile Vaccine Administered As A 3-dose Regimen In Healthy Adults Aged 50 To 85 Years

Clinical Trial Summary

This study will investigate a clostridium difficile vaccine in healthy adults aged 50 to 85 years, who will each receive 3 doses of vaccine. Subjects will receive their vaccine doses at either months 0, 1, and 3 or days 1, 8, and 30. Subjects will be divided into 2 age groups (50-64 and 65-85 years of age).
