Antibody Persistence in Healthy Children After Primary and Booster DTaP-IPV-Hep B-PRP-T Vaccine or Control Vaccine

December 12, 2011 updated by: Sanofi

Antibody Persistence in Healthy South African Children After Primary Series and Booster Vaccination With an Investigational (DTaP-IPV-Hep B-PRP-T) or Control Vaccines

The purpose of this study is to evaluate the long term immunogenicity produced in children by the investigational hexavalent vaccine (DTaP-IPV-Hep B-PRP-T) given in Study A3L15 (NCT 00362336).

Primary Objective: To describe the antibody long term persistence at 3.5 and 4.5 years of age following a 3 dose primary series vaccination of either DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + Oral poliovirus vaccine (OPV) + Engerix™ B vaccination at 6, 10 and 14 weeks of age and a booster vaccination of DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + OPV at 15-18 months

Study Population

Participants aged 3 years and a half on the day of inclusion and must have received the primary series of vaccinations and a booster vaccination in Study A3L15 (NCT 00362336). No vaccination will be provided or administered in this study.

Description

Inclusion Criteria :

  • Aged 3 years and a half on the day of inclusion (42 months ± 60 days)
  • Informed consent form signed by a parent or other legally acceptable representative and by an independent witness if the parent or other legal guardian is illiterate.
  • Subject and parent/ legally acceptable representative able to attend the scheduled visits and to comply with all trial procedures.
  • Receipt of primary vaccination with 3 doses of either DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + Oral poliovirus vaccine (OPV) + Engerix™ B and a booster dose of either DTaP-IPV-Hep B-PRP-T or CombAct-Hib™+ OPV.

Exclusion Criteria :

  • Participation in another clinical trial investigating a vaccine, drug, medical device, or a medical procedure in the 4 weeks preceding the inclusion in the trial.
  • Incomplete primary and booster immunization at trial A3L15.
  • Previous confirmed clinical, serological, or microbiological diagnosis of diphtheria, tetanus, whooping cough, poliomyelitis, Haemophilus influenza b or hepatitis B after completion of A3L15 Study.
  • Subjects known to have received diphtheria, tetanus, pertussis, Haemophilus influenza b and hepatitis B vaccination after completion of A3L15 Study.
  • Any vaccination within 30 days preceding inclusion, except for measles or poliovirus (monovalent) containing vaccines and pandemic influenza vaccines including pandemic H1N1-2009 strain, which may be received at least two weeks before the subject's blood sample collection
  • Blood or blood-derived products received at the latest 3 months before inclusion, receipts of immunosuppressant drugs within the previous 3 months.
  • Known or suspected congenital or acquired immunodeficiency since completion of A3L15 Study.
  • Serious chronic illness occurring after receipt of the primary and booster series (e.g. leukemia, lymphoma [Tor B cells], Crohn's disease).
  • Known or suspected subject seroconversion for human immunodeficiency virus (HIV) or hepatitis C seropositivity since completion of A3L15 Study.
  • Febrile (temperature ≥ 38.0°C) or acute, moderate or severe systemic illness on the day of inclusion.
