Title: Reactogenicity & Immunogenicity Study of Two Doses of GSK Biologicals' Oral Live Attenuated HRV Vaccine Co-administered With Either OPV or IPV in Healthy Infants (Approximately 5-10 Weeks Old) in South Africa
Brief Summary: "The primary objective of this study was to demonstrate that co-administering HRV vaccine with OPV does not induce a significant decrease in poliovirus immune response one month after the third dose of combined vaccines.

The primary objective was reached if one month after the third dose of polio vaccine, upper limit of the 95% CI for the difference in Seroprotection rate between the group B and C pooled and (minus) the group A was below 10% for each polio serotype."
