Symptomatic VCD cases were defined as occurrence of acute febrile illness (temperature >=38°C on at least 2 consecutive days) and confirmation of dengue virus infection by dengue reverse transcriptase polymerase chain reaction and/or dengue NS protein 1 antigen enzyme-linked immunosorbent assay. 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 Vaccine Group.

Dengue hemorrhagic fever cases were defined as number of participants with at least one symptomatic VCD episode meeting the 1997 WHO criteria.
(a) Fever: acute onset, high (>= 38°C) and continuous, lasting 2 to 7 days and (b) any of the pre-listed hemorrhagic manifestations and laboratory findings of thrombocytopenia (platelet <=100 x 109/L) and plasma leakage as shown by hemoconcentation (hematocrit increased by 20% or more) or pleural effusion (seen on CXR) and/or ascites and/or hypoaluminemia. The first two clinical criteria plus thrombocytopenia and signs of plasma leakage are enough to establish a clinical diagnosis of DHF. Dengue hemorrhagic fever 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.
