Summary
The purpose of this study is to determine whether giving the Human Rotavirus Vaccine on alternate dosing schedules will enhance the immune response to the vaccine in a low-resource, high-burden country in Africa. Alternate dosing schedules studied include giving the 2-dose vaccine schedule at a slightly older age and giving an additional dose of the vaccine.
