Study description

The main aim of this study is to collect more information on the effectiveness of TDV when used in a pilot public vaccination program for children and adolescents participating in a community-based cohort in Southeast Asian countries where TDV is already approved for use.

The study will include cohort participants (individual follow-up of 3 years) who may or may not later be vaccinated with TDV as part of a pilot public vaccination program in the study countries.
The study will investigate if cohort participants who were vaccinated with TDV have less hospital stays due to dengue than cohort participants who were not vaccinated with TDV. The study will also provide further information on the effectiveness of TDV against the least common dengue virus serotypes (DENV-3 and DENV-4).
