Active clinical trials for "COVID-19"

Background: Influenza (flu) vaccinations are required for all NIH staff members who have direct contact with patients. COVID-19 vaccines are recommended for persons 6 months of age and older. Researchers want to learn about immunity in NIH staff members who get a flu and/or COVID-19 vaccine. Objective: To understand what happens to the body s immune system throughout the year after getting the flu and/or COVID-19 vaccine. Eligibility: Adults ages 18 and older who work at NIH and plan to get the current season s flu vaccine and/or COVID-19 vaccine. Design: Participants will not get any vaccines as part of this study. Participants will be screened with a medical history and medicine review. They will get a survey via email. It will ask about their flu and SARS-CoV-2 history and vaccinations. Participants will have 12 monthly visits at NIH. If during that year they get both flu and SARS-COV-2 vaccines, their participation will be extended. Once a month, participants will be contacted. They will discuss any new medicines, recent vaccinations, or changes in medical history. Once a month, participants will have blood drawn. Once a month, participants will have nasal sampling. A small, flat absorptive strip will be placed in the nostril to soak up mucus. Participants will press against the outside of their nostril with their finger for 1 minute. Participants may be able to collect samples at home and mail them to NIH if they are not able to visit in person. Participation will last for about 12 13 months.

This is an observer-blind, randomized study which aims to assess the immune response and the safety of two different approved vaccines for first and second dose in healthy adults.

This is a randomized, multi-site, adaptive, open-label clinical trial comparing the immune response to different additional doses of COVID-19 vaccine in participants with autoimmune disease requiring IS medications. All study participants will have negative serologic or suboptimal responses (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result ≤200 U/mL) or a low immune response (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result >200 U/ml and ≤2500 U/mL) to their previous doses of COVID-19 vaccine. The study will focus on 5 autoimmune diseases in adults: Systemic Lupus Erythematosus (SLE) Rheumatoid Arthritis (RA) Multiple Sclerosis (MS) Systemic Sclerosis (SSc), and Pemphigus. This study will focus on 4 autoimmune diseases in pediatric participants: Systemic Lupus Erythematosus (SLE) Juvenile Idiopathic Arthritis (JIA) Pediatric-Onset Multiple Sclerosis (POMS) Juvenile Dermatomyositis (JDM)

The purpose of this double-blind, randomized, controlled study is to assess immunogenicity and safety of 202-CoV at multiple dose levels, administered as 2 injections (i.m) at 28 days apart in adult subjects 18 years of age and above.

Novel coronavirus pneumonia (NCP) and acute respiratory distress syndrome (ARDS) are both associated with the prevailing upper respiratory tract infections caused by the RNA-containing SARS-CoV2 virus of the genius Betacoronavirus of the Coronaviridae family. As both the viral infiltration and infection progress, the host immune system response can be one of a rapidly developing fatal cytokine storm. In the ARDS or NCP ensuing progression, the patient often succumbs to the effects of the hyper pro-inflammatory response, hence contributing to the associated increased mortality as a result of the cytokine storm and associated pathogenesis.

Infectious diseases pose a threat to the life of individuals worldwide. The pandemic has highlighted the need to develop an innovative and cost- effective large population-based screening methodology. The investigators propose a two-fold improvement barcode-labeled testing strategy specifically for pooled samples. This platform combines isothermal amplification and real-time electrochemical detection; electroactive modified loop probes will be used in the amplification step for barcode readout. This method enables four samples pooled detection at the same time. This platform will be integrated into a disposable microfluidic chip that allows minimal human intervention during the process to realize a massively parallel screening platform for infectious disease pathogens. Objectives To develop a sensing method for concurrent electrochemical-tag coded isothermal amplification and real-time electrochemical detection; To design a molecular strategy to barcode four individual samples so that they can be pooled together and to simultaneously amplify and identify a positive individual, if any, from the pooled sample. To fabricate a microfluidic device integrating the sample processor and barcoding module with the nucleic acid amplification and detection step for large-scale population screening of up to 100 individuals. To validate the performance of the prototype using clinical specimens and benchmark it against the detection data from commercially available testing equipment.

The study is designed as an open, non-randomized, phase IV cohort study in which the mRNA vaccine Comirnaty will be given in two doses. Analyses will be performed on blood and saliva, investigating humoral and cellular vaccine responses. Occurence of local or systemic reactogenicity will be evaluated, as well as adverse events. The study will include persons with primary or secondary immunosuppressive disorders, as well as immunocompetent persons, with the aim of investigating if the immune responses after given Comirnaty mRNA vaccine against COVID-19.

The purpose of this study is to evaluate the safety, reactogenicity, and immune response of the SpFN COVID-19 vaccine with Army Liposomal Formulation QS21 (ALFQ) adjuvant in healthy adults ages 18-55.

The purpose of this study is to describe post-intensive care syndrome (PICS) of patients surviving to coronavirus disease 2019 (COVID19) and their rehabilitation and recovery process from hospital to home return

Background: People who get COVID-19 have a wide range of symptoms. They also recover from COVID-19 in different ways. In this study, researchers will use survey data to describe the different ways people experience and recover from COVID-19. They will also use the data to help create future studies to understand why some people do not fully recover. Objective: To learn more about the range and timing of symptoms that people have before, during, and after COVID-19 infection. Eligibility: People ages 18 and older who can give documentation of a positive COVID-19 or antibody test. Design: Participants will be screened with a telephone interview. It will take 15 minutes. They will provide their COVID-19 test results and medical records. Participants will complete a second telephone interview. It will take 30 60 minutes. They will also take online surveys every 3 months for 3 years. The interview and surveys will ask participants about their health before they got COVID-19, what happened while they had COVID-19, and what their recovery has been like. Participants will get log-in data to take the online surveys. Completing all of the surveys the first time may take up to 3 hours. Follow-up surveys will take up to 30 minutes. Participants do not have to complete the surveys in one sitting. They will be able to save their progress and finish the surveys later. Participants may be contacted to take part in other research studies.
