Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations

The study was conducted at 5 international sites – Ghana, Kenya, Mali, Bangladesh, and Vietnam from 29 March 2007 (first patient in) to 13 October 2008 (last dose given).

Last subject completed follow-up: 31 March 2009

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Excluded from the trial before assignment to groups were subjects: with history of active gastrointestinal illness (vomiting, diarrhea, elevated temperature); who were participating in (or expected to participate in) other investigational-product studies; who could not be followed adequately for safety.
