Summary:

      The aim of this study was to investigate the immunogenicity and safety of CYD dengue vaccine
      and Cervarix when administered concomitantly or sequentially in healthy female participants
      aged 9-14 years of age.

      Primary objectives:

        -  To demonstrate that the humoral immune response (in terms of geometric mean titers
           [GMTs]) to Cervarix after concomitant administration with the CYD dengue vaccine is
           non-inferior to the humoral immune response (in terms of GMTs) after sequential
           administration with the CYD dengue vaccine measured 28 days after the last dose of
           Cervarix.

        -  To demonstrate that the humoral immune response (in terms of GMTs) to the CYD dengue
           vaccine after concomitant administration with Cervarix is non-inferior to the humoral
           immune response (in terms of GMTs) to the CYD dengue vaccine after sequential
           administration with Cervarix measured 28 days after the last dose of the CYD dengue
           vaccine.

      Secondary Objectives:

        -  To demonstrate that the humoral immune response (in terms of seroconversion) to Cervarix
           after concomitant administration with the CYD dengue vaccine is non-inferior to the
           humoral immune response (in terms of seroconversion) to Cervarix sequential
           administration with the CYD dengue vaccine measured 28 days after the last dose of
           Cervarix.

        -  To describe the humoral immune response to Cervarix at baseline and after each dose of
           Cervarix in each and any group.

        -  To describe the humoral immune response to the CYD dengue vaccine at baseline and after
           each dose of the CYD dengue vaccine, in each and any group.

        -  To describe the safety of Cervarix and CYD dengue vaccine after each and any dose in
           each group.
    

Eligibility criteria:

             participant (based on local regulations), and/or ICF had been signed and dated by the
             parent(s) or another legally acceptable representative (and by an independent witness
             if required by local regulations).

        Exclusion Criteria:

          -  Participant was pregnant, or lactating, or of childbearing potential (to be considered
             of non-childbearing potential, a female must be pre-menarche, surgically sterile, or

             to the first vaccination and until at least 4 weeks after the last vaccination).

          -  Participation at the time of study enrollment (or in the 4 weeks preceding the first
             trial vaccination) or planned participation during the present trial period in another
             clinical trial investigating a vaccine, drug, medical device, or medical procedure.

          -  Planned receipt of any vaccine in the 4 weeks following any trial vaccination.

          -  Previous vaccination against dengue disease with the trial vaccine.

          -  Known or suspected congenital or acquired immunodeficiency (including HIV infection
             with impaired immune function); or receipt of immunosuppressive therapy, such as

             long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2
             consecutive weeks within the past 3 months).

             microbiologically as reported by participant or parent(s) or another legally
             acceptable representative.

             life-threatening reaction to the vaccines used in the trial or to a vaccine containing
             any of the same substances.
