What is this trial about?
Dengue fever is caused by an infection with the dengue virus. Vaccination with Dengue
Tetravalent Vaccine (TDV) can help prevent dengue fever. The TDV in current formulation
has been approved by health authorities in many countries around the world. The main aim
of the study is to confirm that the TDV new formulation induces the similar immune
response as approved TDV.
Healthy adults who live in an area in which dengue fever does not occur will receive 2
TDV vaccinations 3-months apart with either the new or the current TDV. Blood samples
will be taken before and after the vaccinations. These are necessary to check how well
the vaccine works to activate the immune system. During the study, participants will
visit their study clinic 5 times.
