Primary Endpoints
Percentage of Participants Vaccinated With PR5I With Acceptable Antibody (Ab) Response to Haemophilus Influenzae Type b, Diphtheria, Tetanus, and Poliovirus Types 1, 2 & 3, at 5 Months
One month after post-dose 3 of PRI5 (5 months old)

Antibody titres in the PR5I group were measured by Radioimmunoassay (RIA) for Haemophilus influenzae type b (PRP), Micrometabolic inhibition test (MIT) for diphtheria \& poliovirus, and Enzyme-Linked Immunosorbent Assay (ELISA) for tetanus. Percentage of participants with an Ab titre ≥0.15 μg/mL for Haemophilus influenzae type b (Hib) (polyribosylribitol phosphate, PRP); ≥0.01 IU/mL; for diphtheria \& tetanus; ≥8 (1/dil) for inactivated poliovirus types 1, 2 \& 3 (IPV1, 2 \& 3) are reported. 95% confidence interval (CI) were calculated based on the exact binomial method by Clopper and Pearson. The immune response to PR5I vaccine was considered as acceptable if the lower bounds of the 2-sided 95% CI for the response rates were greater than the predetermined lower CI limits for PRP, diphtheria (80%), tetanus (90%), and IPV1, 2 \& 3 (90%).
