About this study

The goal of this observational study is to learn about the immunity induced by the Qdenga® vaccine in vaccinees. Participants that will receive the Dengue vaccine as part of their routine before a travel will be asked to undergo a blood sample at the time of administration of the first dose (T0), 24-48 hours after the first dose (T1) of the vaccine, immediately before the second dose (T2 ) and one to two months after the second dose (T3). Possibly a further sample will be collected within 2 years.
