Brief Summary:

The aim of this study was to evaluate the administration of CYD dengue vaccine serotypes (1, 2, 3 and 4) following a compressed schedule in 3 different populations.

Primary Objectives:

  • To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue vaccine Dose 3 in Group 1 (Month [M] 13) and Group 2 (M07), irrespective of whether or not Yellow Fever (YF) vaccine has been previously administered.
  • To describe the persistence of the humoral immune response to each of the 4 parental dengue virus serotypes 6 months after CYD dengue vaccine Dose 3 in Group 1 (M18) and Group 2 (M12), irrespective of whether or not YF vaccine has been previously administered.

Secondary Objective:

  • To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue vaccine Dose 1 and Dose 2 in Groups 1 and 2, irrespective of whether or not YF vaccine has been previously administered.
  • To describe the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after CYD dengue Dose 1 in the combined YF-participants in Group 1 (N=60) and Group 2 (N=60), and in Group 3 (N=120).
  • To describe by FV status at baseline the humoral immune response to each of the 4 parental dengue virus serotypes at baseline and 28 days after each injection of CYD dengue vaccine in Groups 1, 2, and 3.
  • To describe the safety profile after each injection of CYD dengue vaccine and/or YF vaccine.

Condition or disease Intervention/treatment Phase
Dengue Dengue Fever Dengue Hemorrhagic Fever Yellow Fever Biological: Live, attenuated, recombinant dengue serotypes 1, 2, 3, and 4 virus Biological: Yellow Fever Phase 2

Detailed Description:
Participants were randomized to 4 different groups to receive either CYD dengue vaccine and/or YF vaccine. Participants who already received YF vaccine prior to enrolment were randomized to one of the 2 groups receiving CYD dengue vaccine alone. Participants were evaluated for immunogenicity, antibody persistence, reactogenicity and safety.
