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 breast milk antibodies, changes in gut microbiota, and genetic susceptibility.The primary Objective of this study is to determine whether decreased vaccine responsiveness to oral poliovirus or rotavirus vaccines is associated with the presence of tropical enteropathy.
Intervention of this study is to vaccinate oral poliovirus vaccine and oral rotavirus vaccine to the child with two group; with inactivated poliovirus vaccine and without inactivated poliovirus vaccine. Rotavirus vaccines give to the child at 10 weeks of age and 17 weeks of age.

Vaccine immunogenicity of oral vaccines (Oral Polio Vaccine and Rotavirus Vaccine) with the presence of tropical enteropathy using Lactose/Mannitol ratio in urine.
Responsiveness of oral vaccines compare with Tropical Enteropathy and without Tropical Enteropathy; using lactose/mannitol ratio.
Time frame: Birth to one year
Systemic immune responses (neutralizing antibodies) of impact of an inactivated polio vaccine (IPV) and polio vaccine boost following vaccination with oral polio vaccine (OPV).
Time frame: Birth to one year
Mucosal immune responses (shedding OPV vaccine virus) of impact of an inactivated polio vaccine (IPV) and polio vaccine boost following vaccination with oral polio vaccine (OPV).
Time frame: Birth to one year
