What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentages of Subjects With RVNA Titer >= 0.5 and Vaccine Group Differences ("4-sites, 1-week" to That of "2-sites, TRC" ID PEP Regimen of the PCEC Rabies Vaccine With or Without HRIG Administration)
Time Frame: Study day 50 (D50)
|
Vaccine group differences are calculated assuming a binomial distribution and the associated confidence interval for the differences in percentage was based on M-N method. Non-inferiority of the immune response of the new "4-sites, 1-week" ID PEP regimen of the PCEC vaccine, with or without HRIG administration, to that of the currently recommended "2-sites, TRC" ID PEP regimen of the PCEC rabies vaccine with or without HRIG administration, as measured by the percentage of subjects with RVNA titer ≥ 0.5 IU/ml at day 50 in the whole study population. |
