Immunogenicity Study of Antibody Persistence and Booster Effect of DTaP-HB PRP~T Combined Vaccine in Filipino Infants
Immunogenicity Study of the Antibody Persistence and Booster Effect of DTaP-Hep B-PRP-T Combined Vaccine at 12 to 18 Months of Age Following a Primary Series at 6, 10 and 14 Weeks of Age in Healthy Filipino Infants Having Received Hepatitis B Vaccine at Birth
DTaP-HB-PRP~T combined vaccine is being developed in order to comply with expanding programs for immunization in infancy, while offering the benefit of a reduced number of injections, and potentially of an increased acceptance.
Primary Objectives:
- To describe the antibody persistence at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP~T or Tritanrix-Hep B/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hepatitis B (Hep B) vaccine given at birth.
- To describe the effect of a booster dose of DTaP-HB-PRP~T on immunogenicity at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP~T or Tritanrix HepB/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hep B vaccine given at birth.
Secondary Objective:
- To describe the safety profile of the booster dose of the DTaP-HB-PRP~T vaccine when administered concomitantly with Oral Polio Vaccine (OPV).

Number of Participants With Antibody Persistence and Immunogenicity Booster Response to Vaccination With DTaP-Hep B-PRP~T Concomitantly With Oral Polio Vaccine (OPV)
Tidsramme: Day 0 (pre-vaccination) and Day 28 post-booster vaccination
|
Immunogenicity 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. Booster responses 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; Pertussis Toxoid and Filamentous Hemagglutinin (FHA) 4-fold increase and booster response. |
