    Abstract

    INTRODUCTION: Dengue virus (DENV) is a serious global health problem. CYD-TDC (Dengvaxia(®)) was the first vaccine to gain regulatory approval to try and address this problem.  AIM: Summarize all available evidence on the immunogenicity, efficacy and safety of the CYD-TDV dengue vaccine.  METHOD: Meta-analysis and systematic review.  RESULTS: The best and worst immunogenicity results were for DENV4 and DENV1, respectively. Vaccine efficacy of 60% was derived from studies with participants aged 2-16 years old, with DENV4 and DENV2 presenting the best and worst results, respectively. Erythema and swelling were more frequent with CYD-TDV. No differences were detected for systemic adverse events.  CONCLUSION: CYD-TDV showed moderate efficacy in children and adolescents. From the immunogenicity results in adults, we can expect satisfactory efficacy from vaccination in this population.
