Efficacy, public health impact and optimal use of the Takeda dengue vaccine.

ABSTRACT: Dengue is the most common arboviral infection, causing substantial morbidity and mortality globally. The licensing of Qdenga, a second-generation vaccine developed by Takeda Pharmaceuticals, is therefore timely, but the potential public health impact of vaccination across transmission settings needs to be evaluated. To address this, we characterized Qdenga's efficacy profile using mathematical models calibrated to published clinical trial data and estimated the public health impact of routine vaccine use. We find that efficacy against both virologically confirmed dengue and hospitalization depends on the infecting serotype, serological status and age. We estimate that vaccination of children aged over 6 years in moderate-to-high dengue transmission settings (average seroprevalence in 9-yea
