Filter by:This is a single-blind, randomised controlled clinical trial to determine the reactogenicity and immunogenicity of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) vaccines (Pfizer-BioNTech or Moderna) as booster dose in adults, who have previously received either Pfizer-BioNTech or AstraZeneca as their primary doses. Both fractional and standard doses of Pfizer-BioNTech or Moderna will be tested. The trial intervention will be given in line with Australian Technical Advisory Group on Immunisation (ATAGI) recommendations for booster vaccine doses which allows booster doses from 5 months onwards . There will be a total of 8 groups, with 100 individuals of even spread of participants above and below 50 years in each group. The trial will be single site, based at Royal Children's Hospital, Melbourne, Australia
Extraordinary times require extraordinary measures. The current COVID-19 pandemic is the paradigmatic example of how infectious diseases may menace the world's health and economy, and particularly contribute to enhancing current inequities in health-related to wealth. The main goal of the proposed study is to understand the epidemiology and natural history of COVID-19 in a rural area in Southern Mozambique
The study is an observer-blind, randomized, controlled prospective intervention study of Phase I. The primary objective is to evaluate the safety and immunogenicity of the SARS-CoV-2 protein subunit recombinant vaccine adjuvanted with Alum+CpG1018
This is a phase 1 study to assess the safety and immunogenicity of different formulations of the investigational adjuvanted recombinant SARS-CoV-2 trimeric S-protein (from beta variant) subunit vaccine (SCB-2020S vaccine), when administered as 2 dose vaccination series 21 days apart to adults ≥18 to ≤75 years of age.
EPOC is designed to examine the feasibility of conducting two point-of-care (POC) tests the LumiraDx SARS-CoV-2 Antibody Test and the RightSign COVID-19 IgG/IgM Rapid Test for SARS-CoV-2 antibodies and compare the reproducibility of these tests to tests run at a central laboratory on specimens obtained from the same study participants at the same time.
This study is designed to evaluate the safety and efficacy of NLC-V in patients diagnosed with COVID-19.
VIDO has developed a vaccine called COVAC-2. The COVAC-2 study vaccine contains a portion of the SARS-CoV-2 spike protein, called S1. The spike protein is the part of the virus that is responsible for attaching to the surface of host cells. COVAC-2 contains a SWE adjuvant. An adjuvant is a compound that is added to a vaccine to help the vaccine produce a better immune response. The SWE adjuvant is similar to another adjuvant, MF59, that is found in influenza vaccines and MF59 containing vaccines have been given to millions of people around the world. The vaccine is expected to stimulate the body to make antibodies against the S1 protein. The antibodies will recognize the viral spike protein if the body is exposed to the virus and prevent severe COVID-19 illness. In animal studies, the immune response generated by the COVAC-2 vaccine was able to protect the vaccinated animals against a severe SARS-CoV-2 infection. This is a Phase 1/2, placebo-controlled, observer-blind, age-stratified randomized, multicenter study to access the safety and immunogenicity of two dosing levels (10 and 25 µg S1 protein tested in parallel) administered once in healthy adults ≥18 of age who have received 2 doses of an authorized COVID-19 vaccine at least 6 months earlier. The study will also include an open-label exploratory study arm to evaluate safety and immunogenicity of a single COVAC-2 dose in previously SARS-CoV-2-infected individuals (Phase 2 only).
Olfactory dysfunction (OD) is a well know symptom of coronavirus disease 2019 (COVID-19), accounting for 48 to 85% of patients. In 1 to 10% of cases, patients develop a chronic olfactory dysfunction (COD,) lasting more than 6 months. Recently, platelet-rich plasma (PRP) was used in patients with non-COVID-19 COD and authors reported encouraging results. In the present study, the investigators investigated the usefulness and safety of PRP injection in 56 patients with COVID-19 COD. Our results showed that PRP in the olfactory cleft can increase the olfactory threshold one month after the injection. Moreover, our results suggest that timing of treatment may be an important factor and that PRP is a safe treatment because no adverse effects were reported throughout the study
Depersonalized multi-centered registry initiated to analyze dynamics of non-infectious diseases after SARS-CoV-2 infection in population of Eurasian adult patients.
COVID-19 infection are characterized by fever and signs of acute respiratory infection. A worsening of respiratory symptoms that can lead to respiratory failure. The decompensation can then be brutal and require rapid recourse to respiratory assistance. The contribution of clinical examination (auscultation and monitoring of oxygen saturation in particular) remains unsatisfactory in predicting an unfavorable course. The interest of pulmonary ultrasound is known in the management of pulmonary infections. However, estimating the severity of lung damage at an early stage could be of great help in monitoring and caring for patients. Ultrasound could meet this need in general practice, the chest scanner is often unavailable in these situations. Ultrasound signs are associated with severe forms. The contribution of pulmonary ultrasound seems particularly interesting in the context of the reassessment of patients during the worsening phase of symptoms (D5-D10). Estimate the prevalence of ultrasound signs in patients with an acute respiratory infection suspected or confirmed to be COVID-19, at the time of the worsening phase (between D5 and D10 of the onset of symptoms). The prevalence of ultrasound lung lesions under COVID-19 may be essential to consider the development of the ultrasound tool in primary care. Indeed, if the contribution of ultrasound is now recognized in intensive care or emergency, its place in general medicine still raises questions.
