Safety and Immunogenicity Study of a Diphtheria, Tetanus, Acellular Pertussis and Poliomyelitis Vaccine (REPEVAX) Followed by 2 Doses of a Diphtheria, Tetanus and Poliomyelitis Vaccine (REVAXIS) in Subjects of 40 Years of Age or Older

Phase 3
Completed
Conditions
Diphtheria
Tetanus
Poliomyelitis
Pertussis
Interventions
Biological: Diphtheria, tetanus, polio and pertussis vaccination
Registration Number
NCT01287949
Lead Sponsor
Sanofi Pasteur, a Sanofi Company
Brief Summary

Primary objective:

* To demonstrate that 3 doses of a vaccine containing Td-IPV valences administered in a 0, 1 and 6-month schedule induce an acceptable immune response in terms of seroprotection rates (SPR) against diphtheria, tetanus and poliomyelitis 1, 2 and 3, in subjects of 40 years of age or older with no diphtheria- and tetanus-containing booster within the last 20 years

* To evaluate the percentage of subjects with antibody titre ≥5 EU/mL (ELISA) for each of the pertussis components (PT, FHA, PRN and FIM) after 1 dose of REPEVAX in these subjects

Secondary objectives:

* If the primary objective is achieved, to determine whether 1 or 2 doses of a vaccine containing Td-IPV valences induce an acceptable response in terms of seroprotection rates (SPR) against diphtheria, tetanus and poliomyelitis 1, 2 and 3, in subjects of 40 years of age or older with no diphtheria- and tetanus-containing booster within the last 20 years

* To describe the immune responses to REPEVAX in these subjects

* To describe the immune responses to REVAXIS administered 1 and 6 months after the administration of REPEVAX in these subjects
