General information about the trial
|

Main objective of the trial |
Evaluation of the pertussis-specific humoral and cellular immunity after vaccination with REPEVAX® or COVAXiS® + IPV Merieux® among 3 groups:
Group A: Adolescents 10-14 years of age who had received five doses of acellular pertussis vaccine and who simultaneously participated in the TRI05 study in which they received either REPEVAX® or COVAXiS® + IPV Merieux® based on on their randomization group.
Group B: Adolescents 10-14 years of age who previously received four doses of acellular pertussis vaccine. Subjects of group B could not participate in the TRI05 study, and in this study received either REPEVAX® or COVAXiS® + IPV Merieux® as recommended by their physician.
Group C: Adolescents 10-14 years of age who previously received four doses of whole-cell pertussis vaccine and had not yet received acellular pertussis vaccine and who simultaneously participated in the TRI05 study in which they had received either REPEVAX® or COVAXiS® + IPV Merieux® based on their randomization group.
|
||
Protection of trial subjects |
Only subjects that met all the study inclusion and none of the exclusion criteria were randomized and vaccinated in the study. Vaccinations were performed by qualified and trained study personnel. Subjects with allergy to any of the vaccine components were not vaccinated. After vaccination, subjects were also kept under clinical observation for 30 minutes to ensure their safety. Appropriate medical equipment were also available on site in case of any immediate allergic reactions.
|
||
Background therapy |
Subjects may have received a 5th consecutive aP immunization at 4 - 6 years of age (which became part of the official German recommendations in March 2006) or have received only 4 consecutive aP or wP immunizations (last dose at 18-24 months). | ||
