Brief 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. The study will assess the safety and tolerability of the vaccine, and also look at the subjects' immune response to the vaccine.

Interventions

0.5 mL intramuscular injection on day 1, day 8, and day 30.

BIOLOGICALPlacebo

Placebo (0.9 percent saline) given as a 0.5 mL intramuscular injection on day 1, day 8, and day 30.
