Brief Summary
This is a prospective randomized clinical trial that aims to evaluate the potential effects of the first dose of rotavirus vaccines on gastrointestinal motility and anatomy and blood and stool cytokine responses. It will also assess the association between these outcomes and the pattern of the shedding of vaccine strain rotavirus in the stool. Infants will be randomized to one of four arms: monovalent rotavirus vaccine (Rotarix®, RV1) alone, RV1 with other recommended vaccines, pentavalent rotavirus vaccine (RotaTeq®, RV5) alone, or RV5 with other recommended vaccines. Data derived from the pilot study will be used to assess the feasibility of conducting a larger scale study.

Outcome Measures
Primary Outcomes (3)
The Effects of RV1 and RV5 With or Without Other Routine Immunizations on Gastrointestinal Anatomy
Number of subjects with an increase in the number of abdominal lymph nodes, as measured by abdominal ultrasound, or an increase of 1 mm or more of terminal ileum wall thickness, as measured by abdominal MRI, from Day 0 (Visit 1) to Day 4-6 (Visit 2)
4- 6 days
The Feasibility of Conducting a Larger Scale Study as Determined by Study Recruitment Rates (Number of Participants Eligible/Participants Who Enrolled)
Study will be determined to be feasible on a larger scale if 10% or more of eligible subjects enroll in the study
15 months
The Feasibility of Conducting a Larger Scale Study as Determined by the Percentage of Participants Who Completed All Study Visits
Study will be determined to be feasible on a larger scale if 70% or more of randomized subjects complete all study visits and remain in the study until completion
15 months
