Filter by:Dengue viruses infect millions of people throughout the tropics and subtropics each year. The development of a dengue vaccine is an important health priority. This study will evaluate the immunologic and clinical response to two dengue vaccines, given 9 months apart, in healthy adults with no history of previous flavivirus infection.
To evaluate the effectiveness of candidate dengue vaccine formulations, it is prudent to develop an appropriate challenge model. To this end, this first-in-human study will examine the safety and effectiveness of the Dengue 1 Live Virus Human Challenge (DENV-1-LVHC) product and assess the ability of this virus strain to elicit an uncomplicated dengue-like illness.
The purpose of this study is to evaluate the safety of and immune response to two doses of a dengue vaccine (TV003) given 6 months apart to healthy adults, adolescents, and children in Thailand.
Dengue viruses are widespread in most tropical and subtropical regions of the world. This study will evaluate the safety and protective efficacy of a dengue vaccine (called TV005) against viremia and rash induced by a DENV-2 vaccine virus (called rDEN2∆30-7169) in healthy adults.
The rationale for a Treatment Use Investigational Device Exemption (IDE) of INTERCEPT PCs is to address current gaps in platelet transfusion safety in selected geographic regions. The objective is to provide access to INTERCEPT PCs for patients who might be at risk of transfusion-transmitted infection (TTI) due to Chikungunya virus (CHIKV) and Dengue virus (DENV) in regions in which a substantial proportion of the population has been infected or is at risk of infection by these pathogens (Petersen 2014); and the risk of asymptomatic infection among qualified blood donors is recognized (Stramer 2012, Adda 2014). The study is designed as a prospective, open label, multi-center, observational study to evaluate the safety and efficacy of INTERCEPT platelet components.
The purpose of this study is to assess the humoral immune responses to three different dose schedules of Takeda's Tetravalent Dengue Vaccine Candidate (TDV) administered subcutaneously in healthy participants between 2 and <18 years of age living in dengue endemic countries.
The potential synergistic effect of administering 2 dengue vaccine candidates that were previously shown to be safe and immunogenic in humans will be evaluated in this study. A prime-boost study of tetravalent dengue virus purified inactivated vaccine (TDENV-PIV) with alum and tetravalent dengue live attenuated virus (TDENV-LAV) vaccine Formulation 17 (F17) will gather data to help better understand the human immune response to dengue vaccination and infection.
The purpose of this study is to evaluate the equivalence of the lyophilized formulation of Takeda's Tetravalent Dengue Vaccine Candidate (TDV) compared with the liquid formulation of TDV.
Dengue viruses can cause dengue illness ranging from a mild illness to life-threatening disease. The purpose of this study is to evaluate the protective effectiveness of a dengue virus vaccine in healthy adults.
The purpose of this study was to conduct a passive surveillance of hospitalized dengue cases in participants who participated in study CYD23 (NCT00842530). The Objectives: - To describe the incidence of virologically-confirmed hospitalized dengue cases. - To characterize hospitalized dengue cases. - To evaluate the occurrence of related and fatal serious adverse events (SAEs).
