Event Rate Per 100 Participant-years for Hospitalized VCD Cases Due to Any and Each Serotype and Meeting World Health Organization (WHO) 1997 Criteria Collected Following Either CYD Dengue Vaccine or Placebo in a Previous Study (CYD23) |
Event rate per 100 participant-years for hospitalized VCD cases, due to any and each serotype (1, 2, 3 and 4) following vaccination with either CYD Dengue vaccine or Placebo in the previous study (CYD23) were reported. Endpoint values <0.1 were rounded to 0.1. The WHO criteria were fever, any haemorrhagic manifestations, thrombocytopenia, plasma leakage or pleural effusion and/or ascites and/or hypoalbuminemia. Dengue haemorrhagic fever was graded as 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 hemorrhages. Grade III: Circulatory failure manifested by rapid and weak pulse, narrowing of pulse pressure (20 mmHg or less) or hypotension, with the presence of cold clammy skin and restlessness. Grade IV: Profound shock with undetectable blood pressure and pulse. |
