ABSTRACT:
The invention features methods and compositions for inducing protective and/or therapeutic immune responses to an antigen in a mammal. In these methods, an antigen is administered to the mammal with a toxin of a Clostridium (e.g., C. difficile), or a fragment or derivative thereof having adjuvant activity.
