 Randomisation: Randomisation will be conducted at the individual level, stratified by geographic area and randomized in blocks of size four to insure equal numbers of babies in each treatment group. Each pregnant woman will be assigned a unique study number at the time of enrollment. Each set of capsules two 25,000 IU capsules for the newborn will be packaged separately and labelled with the womans name, address, and ID number to avoid mix-ups at the time of delivery. Treatment assignment codes will be kept in a locked filing cabinet in a sealed envelope at a location separate from the study headquarters.
