Trial overview
Official title: Evaluation of GSK Biologicals’ dTpa booster vaccine in adults, given 10 years after previous dTpa boosting.
Trial description: The purpose of this study is to assess the efficacy and safety of repeating dTpa booster in adults 10 years after previous booster vaccination with dTpa in a previous clinical study (NCT01267058). Only subjects who received the booster vaccination in a previous clinical study are eligible for participation in this study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.No new recruitment will be performed in this booster phase (see inclusion criteria).
