Vaccine efficacy was defined as 1 minus the ratio of density incidence due to any serotype after at least 1 dose in the CYD Dengue Vaccine Group over the density incidence of the Placebo Group.

Number of Symptomatic VCD Cases Meeting World Health Organization (WHO) Criteria Throughout the Trial Due to Any Serotype Following Injection With Either CYD Dengue Vaccine or a Placebo

Dengue hemorrhagic fever (DHF) cases were defined as number of participants with at least one symptomatic VCD episode meeting the 1997 WHO criteria.

The first two clinical criteria plus thrombocytopenia and signs of plasma leakage are enough to establish a clinical diagnosis of DHF. DHF was graded as follows: Grade I: Fever accompanied by non-specific constitutional symptoms; the only hemorrhagic manifestation is a positive tourniquet test; Grade II: Spontaneous bleeding in addition to the manifestations of Grade I participants, usually in the form of skin and/or other hemorrhage.

5. Study Description

Brief Summary

The aim of the study was to assess the efficacy of Sanofi Pasteur's CYD dengue vaccine in preventing symptomatic virologically-confirmed dengue cases for dengue-endemic areas of Latin America. Primary Objective: To assess the efficacy of CYD dengue vaccine after 3 vaccinations at 0, 6, and 12 months in preventing symptomatic virologically-confirmed dengue (VCD) cases, regardless of the severity, due to any of the four serotypes in children and adolescents aged 9 to 16 years at the time of inclusion. Secondary Objectives: To describe the efficacy of CYD dengue vaccine in preventing symptomatic VCD cases after the third dose to the end of the Active Phase, after at least 1 dose, and after 2 doses. To describe the occurrence of hospitalized VCD cases and the occurrence of severe (clinically severe or as per World Health Organization (WHO) criteria) VCD cases, throughout the Surveillance Expansion Period (SEP) and throughout the trial (from Day 0 until the end of the study). To describe the antibody response to each dengue serotype after Dose 2, after Dose 3, and 1 and 5 years after Dose 3. To describe the occurrence of serious adverse events (SAEs), including SAEs of special interest in all participants throughout the trial period.

Detailed Description

Participants were randomized to either receive 3 injections of CYD dengue vaccine or a placebo at 0, 6, and 12 months. A subset of participants from each country (N=2000) was also evaluated for reactogenicity and immunogenicity. For each participant, the Active Phase of dengue case detection began after the first injection (Dose 1) and continued until 13 months after the third injection (Dose 3). It was assumed that 12 months of surveillance should result in the detection of a sufficient number of VCD cases to allow for an assessment of efficacy. The Hospital Phase began after the Active Phase. Participants with a febrile illness and requiring hospitalization were screened for dengue until the end of the study. Participants who consented to participate in the SEP were actively followed for dengue case detection (i.e. at least weekly contact and capturing any acute febrile illness, not just hospitalized febrile cases, as in the Active Phase). The SEP was designed to maximize the detection of symptomatic VCD (hospitalized or not) in order to describe CYD dengue vaccine efficacy and safety in preventing symptomatic dengue in the long-term. Participants who declined participating in the SEP continued surveillance as in the Hospital Phase until trial completion. Symptomatic VCD cases occurring more than (>) 28 days after dose 3 (during the Active Phase) are defined as: Acute febrile illness (i.e. temperature >=38 degree Celsius (°C) on at least 2 consecutive days) Virologically confirmed by dengue Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) and/or dengue non-structural (NS)1 enzyme-linked immunosorbent assay (ELISA) Ag test. Severity was assessed using a definition consistent with the 1997 WHO Classification Dengue Hemorrhagic Fever and by an independent Data Monitoring Committee (IDMC) severity criteria.
