Filter by:In the absence of a vaccine, the spread of SARS-CoV-2 can only be mitigated via non-pharmaceutical interventions that reduce the risks of forward transmission. Currently, European policymakers are implementing combinations of fierce pandemic control measures. However, there is substantial uncertainty on the transmission dynamics of SARS-CoV-2 and, consequently, the effect of each specific mitigation intervention as well as their joint impact on the pandemic evolution. Moreover, it is uncertain how and when the Public Health response should be modified once the pandemic starts to slow. There is an urgent need for data that can help to further unravel the key transmission characteristics of SARS-CoV-2 in the population. Household studies are, therefore, a useful approach to obtain insight into the main determinants of transmission and to derive estimates of transmission parameters. By fully characterizing the critical process of SARS-CoV-2 household transmission and how they vary by patient and household characteristics, infection dynamics in the population can be further elucidated. Responding to SARS-CoV-2 effectively from a community care perspective will also require understanding the perceptions, beliefs, and actions taken by patients and the public. A 'bottom-up' understating of such issues is critical to understand how best to design effective community strategies. Rapid European COVID-19 Emergency Research response (RECOVER) is a project involving ten international partners that have been selected for funding by the European Union under the Horizon 2020 research framework. RECOVER responds to call topic SC1-PHE-CORONAVIRUS-2020: Advancing knowledge for the clinical and public health response to the SARS-CoV-2 epidemic and builds on many years of investment by the European Commission in clinical research preparedness for epidemic response. RECOVER will therefore provide a range of data and analytical results to guide the Public Health response, including the here described household transmission study. Objective: Estimate key transmission parameters of SARS-CoV-2 in Europe from observing within household virus spread and seroconversion of household members and characterize the views and experiences of households regarding perceptions, practices regarding infection control, and impacts of imposed isolation measures.
The primary goal of this study is to evaluate the safety, reactogenicity, and immunogenicity of mRNA-1073 compared to co-administered mRNA-1010 and mRNA-1273 vaccines and to the individual vaccines alone in healthy participants.
This study will investigate antibody levels with respect to time since receiving a COVID-19 booster shot. The study will be decentralized, where participants can complete all study tasks at home. Self-reported participant information will be collected via surveys conducted at intake and monthly throughout the study. Participants will also perform monthly at-home capillary blood draws via YourBio devices that will be mailed to the designated laboratory for sample processing and antibody testing.
The goal of this study is to compare real-world effectiveness of the mRNA-1273 vaccine versus the BNT162b2 vaccine on medically attended COVID-19 and COVID-19 hospitalizations among fully vaccinated immunocompromise participants.
Phase Ⅱ Clinical Trial to Evaluate the Safety and Immunogenicity of the New Coronavirus mRNA Vaccine (LVRNA009) in Chinese People Aged 18~59 Years
This is a research study to evaluate the clinical utility of the Enhanced Preservation Media with Integrated Extraction (EPM-IX)
Lung transplant recipients have poor outcomes after COVID-19 infection with mortality. Due to the immunosuppression, they have had poor responses to SARS-CoV-2 vaccine and remain at high risk of poor outcomes. This is a Phase I/II clinical trial to evaluate the safety and immune response from a higher dose mRNA-1273 vaccine among lung transplant recipients who have already received three or four doses of the COVID-19 vaccine.
This is a study of two experimental SARS-CoV-2 vaccines against the virus called SARS-CoV-2 virus. The first of the experimental vaccines is called DoCo-Pro-RBD-1 + M59® and contains a laboratory made protein which looks the same as a protein in the SARS-CoV-2 virus. As this protein is so similar to a protein in the SARS-CoV-2 virus, it allows the immune system to develop immunity against the real virus by producing specific antibodies against this protein. Antibodies are substances in the blood which could help protect against future infection. The second of the experimental vaccines that will be tested is called MIPSCo-mRNA-RBD-1. This type of vaccine uses messenger ribonucleic acid (mRNA) which is a set of instructions for a cell to make a viral protein called an antigen. Antigens are substances that can trigger the body's defences to produce antibodies that fight against the disease. This study will test these two experimental COVID-19 vaccines in people who have previously received two doses of ComirnatyTM (Pfizer Australia Pty Ltd) or VaxzevriaTM (AstraZeneca Pty Ltd) and a third booster vaccination with either ComirnatyTM or SpikevaxTM (Moderna). This study is the first time this recombinant protein vaccine and this mRNA vaccine will be given to humans. The purpose of this study is to determine what amount, or dose, of the experimental vaccines is safe and produces the desired immune response and antibody level for future investigations. It will do this by testing 3 different dose levels for each of the two vaccines. Each participant will receive a single vaccine at one of the three dose levels, or a placebo injection. This study is the first time this recombinant protein vaccine and this mRNA vaccine will be given to humans.
Prevention of COVID-19 caused by SARS-CoV-2.
This is a 2-part study to evaluate the immunogenicity, safety, and reactogenicity of mRNA-1273.529 and mRNA-1273.214 administered as a booster dose.
