Filter by:The primary objective of the study is to identify any suspected dengue case in subjects that received at least one dose of the CYD dengue vaccine who were classified as seronegative or undetermined at baseline (according to PRNT50 at baseline, or anti-non-structural protein 1 [NS1] test Post-dose 3) in the Colombian study sites of CYD15, CYD13, CYD29, CYD64, CYD65 trials in order to allow appropriate access to care until the completion of 10 years after the last CYD Dengue Vaccine received by each participant
The purpose of this study is to describe antibody persistence for each of the 4 dengue serotypes for up to 63 months after the first vaccination in the primary vaccination series for participants from parent trial DEN-315 (NCT03341637) (Mexico) and for up to 36 months after the first vaccination in the primary vaccination series for participants from parent trial DEN-304 (NCT03423173) (United States [US]) and to describe the impact of a tetravalent dengue vaccine (TDV) booster dose vs placebo on antibody response for each of the 4 dengue serotypes at 1 month and 6 months post administration of the TDV booster or placebo.
This is an observational study for 5 years, and aims to determine the risk of developing dengue among Philippine children who are eligible to receive the dengue vaccine during the DOH mass dengue vaccination, by dengue serostatus at baseline.
The aim of this study is to evaluate the safety profile of Dengvaxia® when used in the real-world immunization setting Primary Objective: - To measure the incidence of selected adverse events (AEs) and serious AEs (SAEs) occurring over a period of six (6) months after each Dengvaxia® dose administration; - To quantify the association between Dengvaxia® and each of the selected AEs and SAEs for which a risk window after vaccination can be defined, using estimates of relative risk - To monitor the occurrence and frequency of hospitalized dengue disease as well as any other SAEs leading to hospitalization or death, including new and previously unrecognized SAEs, following Dengvaxia® administration on a longer term (up to 5 years after the first Dengvaxia® dose administration. Secondary objectives: - To identify risk factors for hospitalized dengue disease (severe or not) among subjects vaccinated with Dengvaxia®; - To describe the frequency of hospitalized dengue disease and/or other SAEs or selected AEs according to the number of Dengvaxia® doses and/or interval between doses.
