结局指标
主要结局
Number of Participants With Seroprotection for Anti-Hep Bs, Anti-PRP, Anti-Tetanus, and Anti-Diphtheria Antibodies After Vaccination With Either DTaP-Hep B-PRP~T Concomitantly With OPV or Tritanrix-Hep B/Hib™ Concomitantly With OPV
时间窗: 1 month post third vaccination
Seroprotection was assessed by means of radioimmunoassay (RIA) for anti-Hepatitis B (Hep Bs) and anti-PRP antibodies, enzyme immunoassay (EIA) for anti-Tetanus, and serum neutralization (SN) for anti-Diphtheria. Seroprotection was defined as titers ≥ 10 mIU/mL for anti-Hep Bs; ≥ 0.15 μg/mL for anti-PRP; ≥ 0.01 IU/mL for anti-Tetanus and anti-Diphtheria at 30 days after the third vaccination.
Number of Participants With Observed High Fever During the 7-Day After Vaccination With DTaP-Hep B-PRP~T Concomitantly With OPV or Tritanrix-Hep B/ Hib™ Concomitantly With OPV.
时间窗: Day 0 to Day 7 post-vaccination
Occurence of at least one high fever episode (≥ 39.6ºC rectal temperature equivalent) observed within 7 days after any of the three injections.
次要结局
- Number of Participants Reporting At Least One Solicited Injection Site Reaction or Systemic Reactions Following Each Vaccination With Either DTaP-Hep B-PRP-T Concomitantly With OPV or Tritanrix-Hep B/Hib™ Concomitantly With OPV(Day 0 to Day 7 after vaccination)
- Geometric Mean Titers (GMTs) of Vaccine Antibodies After Vaccination With Either DTaP-Hep B-PRP-T Concomitantly With OPV or Tritanrix-Hep B/Hib™ Concomitantly With OPV(1 month post third vaccination)
