Study of ChimeriVax™ Tetravalent Dengue Vaccine in Healthy Subjects
March 15, 2022 updated by: Sanofi Pasteur, a Sanofi Company
Immunogenicity and Safety of ChimeriVax™ Tetravalent Dengue Vaccine in Healthy Subjects Aged 2 to 45 Years in Viet Nam
This trial evaluated the use of a tetravalent vaccine against dengue.
Primary objectives:
- To describe the humoral immune response to dengue before and after each vaccination with tetravalent dengue vaccine in adults, adolescents, and children.
- To evaluate the safety of each vaccination with tetravalent dengue vaccine in the 4 age cohorts.
- To evaluate the persistence of antibodies against dengue during 5 years after the first vaccination with tetravalent dengue vaccine in the 4 age cohorts.
