August 5, 2013 -- Sanofi Pasteur, the vaccines division of Sanofi (EURONEXT: SAN and NYSE: SNY), announced today the initiation of its Phase III clinical program called Cdiffense to evaluate the safety, immunogenicity and efficacy of an investigational vaccine for the prevention of primary symptomatic Clostridium difficile infection (CDI).
