Summary:

      The aim of the study was to assess the safety and immunogenicity of the CYD dengue vaccine
      and Gardasil (Human Papillomavirus Quadrivalent [Types 6, 11, 16, and 18] Vaccine,
      Recombinant) when administered concomitantly or sequentially.

      Primary objectives:

        -  To demonstrate that the humoral immune response (in terms of geometric mean titers
           [GMTs]) to Gardasil after concomitant administration was non-inferior to sequential
           administration with the CYD dengue vaccine measured 28 days after the last dose of
           Gardasil.

        -  To demonstrate that the humoral immune response to the CYD dengue vaccine after
           concomitant administration was non-inferior to sequential administration with Gardasil
           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 Gardasil
           vaccine after concomitant administration was non-inferior to sequential administration
           with the CYD dengue vaccine measured 28 days after the last dose of Gardasil.

        -  To describe the humoral immune response to Gardasil at baseline and after each dose of
           Gardasil 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 Gardasil and the CYD dengue vaccine after each and any dose in
           each group.
    

Eligibility criteria:

        Inclusion Criteria:

          -  Participants aged 9 to 13 years (i.e., from the day of the 9th birthday to the day

             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).

          -  Participant (or participant and parent[s] or another legally acceptable

             of non-childbearing potential, a female had to be pre-menarche, surgically sterile, or
             using an effective method of contraception or abstinence from at least 4 weeks prior
             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.

          -  Previous vaccination against human papillomavirus (HPV) disease with either the trial
             vaccine or another vaccine.

             immunodeficiency virus infection with impaired immune function); or receipt of
