Background: Early evidence in the COVID-19 pandemic suggests that smokers are at a higher risk of having severe effects or dying from the disease. Smoking causes changes in immune cells. Researchers think this may be the reason why smokers are more likely to have severe effects from COVID-19. Researchers want to better understand the interaction between smoking history, the immune system, and COVID-19. Objective: To better understand how COVID-19 affects smokers and non-smokers immune systems before and after being infected with the virus. Eligibility: Healthy people ages 30-55 who are a smokers or non-smokers who may potentially contract COVID-19 Design: Participants will be screened over the phone. They will answer questions about their demographics, medical history, medications, and smoking status. Participants will have up to 6 monthly visits. At the first visit, participants will have blood tests. Blood will be drawn through a needle in an arm vein. They will provide a saliva sample in a container and have a cheek swab. The participant will also have a nasal swab to see if they currently have COVID-19. Their height and weight will be taken. They will complete questionnaires about their medical history and smoking status. Participants will then have monthly visits. They will have blood draws to test for COVID-19 antibodies. They will provide a saliva sample in a container and have a cheek swab. The participant will also have a nasal swab to see if they currently have COVID-19. These visits will occur 4 times or until they have a positive antibody result. Participants will have a final visit. They will have blood tests. They will provide a saliva sample in a container and have a cheek swab. The participant will also have a nasal swab to see if they currently have COVID-19. If at any time participants test positive for a COVID-19, they will be rescheduled 14 days or more after they no longer have symptoms....

Background: COVID-19 can cause problems in different parts of the body. For most people, it causes fevers or trouble breathing. Some people might not recover all the way. Researchers want to see if a treatment can help with people who have recovered from COVID-19 but still have symptoms ("Long COVID"). Objective: To learn if human immunoglobulin (IVIG) will help with neurological symptoms of Long COVID. Eligibility: Adults ages 18 and older who had COVID-19 at least 12 weeks ago and have ongoing neurologic symptoms, such as dizziness, trouble walking, or problems with strength. Design: Participants will be screened with a medical record review. Participants will have a medical history and a physical exam and complete questionnaires about their health and quality of life. They will have a spinal tap. They will give blood samples. They will discuss their symptoms with a neurologist and have a neurological exam. Participants will take memory and thinking tests using a tablet. The tests will take 1 hour to complete. They will also take a smell and taste test. It will take approximately 30 minutes to complete. Participants will lie on a table that tilts for up to 40 minutes. Their blood pressure and heart rate will be monitored. Blood will be taken through an intravenous (IV) catheter. Participants will receive either IVIG, or saline by IV for 5 days. Then the participants will receive IVIG if they first received saline or saline if they first received IVIG by IV for another 5 days. They will not know what they receive. Participants will have an MRI of the brain if they have not had one recently. They will receive a contrast agent by IV as part of the MRI scan. Participants will be on the study for up to 4 months. They will have follow-up visits at the clinical center as well as fill out questionnaires at home. They may be asked to continue follow-up....

Researchers are looking for other ways to prevent severe illness from COVID-19. COVID-19 is a virus that most often causes mild flu or cold-like symptoms. However, people with certain health conditions or other factors have a high risk (chance) of getting severely ill from COVID-19, which can require a hospital stay or lead to death. Some people who are high risk for severe illness may be unable to take certain treatments for COVID-19 because they are not available to them, or they take other medicines that may react with a treatment and cause an unwanted effect. Molnupiravir (MK-4482) is a study medicine designed to stop the COVID-19 virus from copying itself in the body (multiplying). The goal of this study is to learn if molnupiravir prevents severe illness from COVID-19 more than placebo in people who are high risk.

This phase II trial compares the effect of the GEO-CM04S1 vaccine with the current standard of care vaccine in preventing COVID-19 infections in patients with chronic lymphocytic leukemia (CLL). The GEO-CM04S1 vaccine uses a modified vaccinia virus (MVA) backbone that may be more effective at boosting COVID-19 immunity in patients with poor immune responses. MVA strongly induces T cell expansion (infection fighting blood cells) even in the background of a suppressed immune system, which is the case in the targeted CLL patient population. Using the GEO-CM04S1 vaccine may be more effective at preventing COVID-19 infection in patients diagnosed with CLL.

This is a phase I trial followed by a phase II randomized trial. The purpose of phase I study is the feasibility of treating patients with acute respiratory distress syndrome (ARDS) related to COVID-19 infection (COVID-19) with cord blood-derived mesenchymal stem cells (MSC). The purpose of the phase II trial is to compare the effect of MSC with standard of care in these patients. MSCs are a type of stem cells that can be taken from umbilical cord blood and grown into many different cell types that can be used to treat cancer and other diseases. The MSCs being used for infusion in this trial are collected from healthy, unrelated donors and are stored and grown in a laboratory. Giving MSC infusions may help control the symptoms of COVID-19 related ARDS.

Background: The COVID-19 pandemic has challenged the health systems worldwide. Many tools have been developed in response to the pandemic, but there is no current way to quickly screen multiple people for the disease. Research has shown that people with COVID-19 have higher levels of some proteins involved in the immune response and inflammation. These proteins can be detected in sweat using a special camera. Researchers want to see if analysis of sweat from fingerprints could be used to detect COVID-19 infection in people. Objective: To test a new technology to detect COVID-19 infection based on an analysis of sweat from fingerprints. Eligibility: Adults ages 18 and older who tested positive or negative for COVID-19 within the last 7 days. Design: Participants will visit the NIH Clinical Center for one day within 7 days from COVID-19 testing. The visit will last for 3 to 4 hours. Participants who show symptoms for COVID-19 with a positive test will give blood samples to correlate with the sweat markers. About 1/2 tablespoon of blood will be drawn. For sweat markers, 10 fingers will be imaged by a camera using a touchless system. This will be repeated 3 times. It will take about 15 minutes. Participants will use the device. They will get instructions and watch a short video on how to use the device.

This Phase 1 clinical trial will evaluate the safety, reactogenicity, and immunogenicity of PepGNP-COVID19, a synthetic nanoparticle-based, T cell-priming peptide vaccine against SARS-CoV-2, when administered as a booster dose in healthy adults. PepGNP-COVID19 is designed to induce broad and durable T cell-mediated immune responses by delivering conserved SARS-CoV-2 peptides covalently bound to carbohydrate-coated gold nanoparticles, with the goal of enhancing tissue-resident cytotoxic T lymphocytes in the respiratory tract and reducing the need for frequent antigen updates. This randomized, participant-blinded, dose-ranging, multi-site trial will enroll 60 healthy adults aged 18-64 years, with a target of 8 of 20 participants in each cohort being > / = 50 years of age. Participants will receive a single intradermal injection of PepGNP-COVID19 at one of three dosage levels (0.83 nmol, 2.5 nmol, or 7.5 nmol in a volume of 0.05 mL). The primary objective is to evaluate the safety, reactogenicity, and tolerability of a single intradermal dose of PepGNP-COVID19 at three dosage levels in previously vaccinated healthy adults.

Growing evidence indicates that many people who have chronic post-acute sequelae of SARS-CoV-2 infection (PASC) will experience ongoing neurological and musculoskeletal impairment that can affect gait and balance. Identifying the factors contributing to these impairments and how they influence functional mobility is the first step towards creating effective evaluation and treatment protocols. In this study the investigators will examine cognition, vision, proprioception, muscle strength, gait and balance in persons with and without PASC to understand how PASC may impact functional mobility through a cognitive-sensorimotor lens. Gait and balance will be studied in environments that stress cognitive and sensory abilities. Study outcomes will be critical for the development of evidence-based Veteran Health Administration diagnostic and standard-of-care protocols to address gait and balance dysfunction in Veterans with PASC for restoring their functional mobility and independence.

Mental health vulnerability due to stress is increased America due to disproportionate effects of social factors such as racism, poverty, education, and criminal justice sentencing. Various meditation and mindfulness approaches have provided evidence of measured reductions in multiple negative dimensions of stress. However, the majority of these studies do not have an adequate representation of Persons of African Descent(PAD) or other marginalized groups and are not designed to be culturally relevant or community based. Music has been shown to alleviate multiple symptoms of stress and has been shown to be a preferred and effective support for meditation and mindfulness. However, its role in stress management in PADs engaged in meditation or mindfulness is seldom studied. This study aims to evaluate the effects of a community-based music mindfulness program on stress management in PAD community members with anxiety and depression during COVID19. Component 2c.

The platform protocol is designed to be flexible so that it is suitable for a range of study settings and intervention types. Therefore, the platform protocol provides a general protocol structure that can be shared by multiple interventions and allows comparative analysis across the interventions. For example, objectives, measures, and endpoints are generalized in the platform protocol, but intervention-specific features are detailed in separate appendices. This platform protocol is a prospective, multi-center, multi-arm, randomized controlled platform trial evaluating potential interventions for PASC-mediated sleep disturbances. The hypothesis is that symptoms of sleep and circadian disorders that emerge in patients with PASC can be improved by phenotype-targeted interventions. Specific sleep and circadian disorders addressed in this protocol include sleep-related daytime impairment (referred to as hypersomnia) and complex PASC-related sleep disturbance (reflecting symptoms of insomnia and sleep-wake rhythm disturbance).
