Filter by:1. Deploy wearable COVID sensor to collect high resolution physiological data (temperature, cardiac, respiratory and physical activity) from COVID positive patients. 2. Use collected data to train algorithm for assessing the risk of individuals presenting with symptoms suggestive of COVID-19.
This is a single center, open-label, parallel controlled, and randomized Phase II clinical trial to evaluate the safety and immunogenicity of two types of Recombinant Novel Corona Virus Vaccine (Adenovirus type 5 vector) in population aged 6-17 years who have been previously immunized with 2 doses of inactivated COVID-19 vaccine. This is to evaluate the safety and immunogenicity of different heterologous prime-boost regimen in this population.
The aim of the study is estimating the predictive and preventative capability of thrombodynamics for severe pneumonia coagulopathy complications in patients with COVID-19 infection. Thrombodynamics test is a method for blood coagulation and anticoagulation monitoring. It could be a useful tool for predicting thrombohemorrhagic complications in patients with COVID-19 infection and developing a novel scheme of anticoagulant therapy. Inclusion criteria are the following: patient informed concern, confirmed COVID-19 diagnosis, state of modern or critical condition.
This is a phase Ⅳ follow-up clinical trial based on the previous Phase Ⅳ clinical trial of an inactivated COVID-19 vaccine (CoronaVac) manufactured by Sinovac Life Sciences Co., Ltd.The purpose of this study is to evaluate the immunogenicity,safety and cross-immune response of booster immunization using COVID-19 vaccine,to compare the similarities and differences of immune responses between primary immunization and booster immunization and to detect antibody against hepatitis A and evaluate the immune persistence of the one dose immunization schedule of hepatitis A vaccine in healthy population aged 18 years and older.
To understand the long-term epidemiology, develop effective risk-prediction and stratification tools, and understand the pathobiology of kidney disease in COVID-19 survivors.
Randomized-controlled trial comparing homologous (mRNA vaccine) vs. heterologous (vector vaccine) for third SARS-CoV-2 vaccine dose in kidney transplant recipients not responding to initial prime-boost vaccination with an mRNA vaccine.
The Australian government swift interventions and actions early to the COVID 19 epidemic included enforced quarantine, isolation, varying degrees of social and physical distancing measures, travel restrictions, community level testing and enhanced contact tracing models which effected the trajectory of the epidemic impact. While the search for effective therapeutics and vaccines continues, it is important to understand how to effectively implement and optimise the current public health interventions available; application of traditional contact tracing , contributions of new contact tracing mobile phone applications, community level testing and use of specific fit for purpose diagnostic tests; to screen, detect and provide evidence of infection clearance. While the suppression measures have been effective on disease transmission rates, it has had economic, social and non COVID-19 health costs impacts. As community restrictions change it will be important to monitor and evaluate the effectiveness of these key interventions. This is a longitudinal study that will follow the experience and behaviors of 2 key risk populations impacted by COVID-19 transmission containment measures.
The study is a randomized, double-blind, and positive-controlled Phase III booster study. It will evaluate the immunogenicity and safety of one dose of SCTV01C or SCTV01E as booster compared with either one dose of Sinopharm inactivated COVID-19 vaccine (Cohort 1) or one dose of Comirnaty (Cohort 2).
Study on Clinical Use of EVUSHELD (AZD7442) as Pre-exposure Prophylaxis in the Real-world Setting - A Multi-Centre Observational Prospective Study to Determine the Utilization and Clinical Outcomes of EVUSHELD in Gulf Cooperation Council Countries
The purpose of this double-blind, randomized, controlled study is to assess safety, reactogenicity, and immunogenicity of ZR-202-CoV, administered as 2 injections (i.m) at 28 days apart in adult subjects 60 years of age and above.
