Purpose
Oral polio and rotavirus vaccines are significantly less effective in children living in the developing world. Tropical enteropathy, which is associated with intestinal inflammation, decreased absorption and increased permeability, may contribute substantially to oral vaccine failure in developing country settings. Other possible causes of oral vaccine underperformance include malnutrition, interference with maternal or breastmilk antibodies, changes in gut microbiota, and genetic susceptibility.
Primary Objective: to determine whether tropical enteropathy impairs the efficacy of oral polio and rotavirus vaccines in children in Bangladesh.
Secondary Objectives: 1) to determine the impact of an inactivated polio vaccine (IPV) boost on the efficacy of oral polio vaccine and 2) to determine the efficacy of oral rotavirus vaccine to prevent rotavirus diarrhea
