Background: The COVID-19 global pandemic killed more than 6 million people worldwide. Several vaccines have been developed against the virus that causes this disease. These vaccines are effective at preventing severe symptoms and death from COVID-19. Some people with chronic liver disease, especially those with an advanced condition called cirrhosis, do not respond to many vaccines as well as healthy people do. The goal of this natural history study is to find out how well people with chronic liver disease respond to the COVID-19 vaccines. Objective: To learn how chronic liver disease affects the body s immune response to vaccination against COVID-19. Eligibility: People aged 18 years or older with chronic liver disease. They must also be enrolled in protocol 91-DK-0214 or 18-DK-0091. Design: Participants will have 3 visits, each spaced 6 months apart. Each visit will last 2 hours. Participants will have their vital signs recorded. These include age, sex, race, height, and weight. They will give their medical history. At each visit, participants will have blood drawn through a needle inserted into a vein in the arm. The sample drawn at each visit will be from 1 to 8 tablespoons. At each visit, participants will fill out a questionnaire. They will answer questions about whether they have been vaccinated against COVID-19; whether they have had COVID-19; and whether they have been exposed to someone who had COVID-19. The questionnaire will take 10 to 15 minutes. Researchers will also look at results of past blood tests from other research studies.

This is an appendix of master protocol (NCT05595369) designed to be flexible so that it is suitable for a wide range of settings within health care systems and in community settings where it can be integrated into COVID-19 programs and subsequent treatment plans. This sub-study is a prospective, multi-center, double-blind, randomized, controlled trial evaluating nirmatrelvir/ritonavir (Paxlovid) in two dosing durations for the treatment of Post-Acute Sequelae of SARS-CoV-2 Infection (PASC). The study is evaluating potential mechanisms of action, efficacy, and safety of antivirals and other therapeutics in individuals with PASC, according to the platform protocol objectives. The hypothesis is that persistent viral infection and/or overactive/chronic immune response and inflammation are underlying contributors to PASC and that antiviral and other applicable therapies may result in viral clearance or decreased inflammation and improvement in PASC symptoms.

This study entitled Community-Centered Interventions for Improved Vaccine Uptake for COVID-19 (CIVIC): Getting to Yes, Michigan!, is designed to increase vaccine uptake among populations that experience COVID-19 related disparities. The investigators will focus on the four counties within Michigan where a disproportionate burden of COVID-19 is within African Americans and Latinx communities, i.e., Wayne, Genesee, Kent and Washtenaw Counties. Using a community-based participatory research (CBPR) approach, CIVIC will leverage: its long term relationships with the communities involved, an established CBPR Steering Committee developed and the knowledge gained as a Community Engagement Alliance (CEAL) grant recipient, the resources and networks of the University of Michigan CTSA (MICHR), and the expertise of our academic partners to identify and understand factors that contribute to COVID-19 vaccine hesitancy in African Americans and Latinx communities in Michigan. The investigators will develop and test interventions based on community-centered approaches to achieve a primary goal of increased vaccine uptake. The investigators will achieve this goal with the following aims: 1. Increase understanding of the barriers and drivers of vaccine uptake and hesitancy; 2. Increase vaccine uptake and decrease vaccine hesitancy through the implementation and evaluation of a multi-component intervention; and maintain, enhance, and evaluate the effectiveness of the CIVIC partnership to equitably engage all partners.

Background: Vaccines against SARS-CoV-2, the virus that causes COVID-19, have been highly effective against preventing severe disease. But the protective effects of these vaccines appear to wane over time. Researchers want to learn why. Objective: To learn more about how the immune system responds to vaccines against infections like SARS-CoV-2. Eligibility: Healthy adults ages 18 or older who are scheduled to receive either a new vaccine or a booster shot against SARS-COV-2 or another emerging infection. Design: Participants will be screened with a medical history and blood and urine tests. Participants will have up to 8 study visits in 1 year. Each visit should last less than 2 hours. At each visit, participants will give blood samples. Some blood samples will be used for genetic testing. They will also give updates on their health. After the first study visit, participants will receive either a first vaccination or a booster shot. They must get the vaccine in their community or workplace. They will not get the vaccine at NIH. This study currently focuses on SARS-CoV-2, but it will expand to other infectious diseases as they emerge and become the target of new vaccines. ...

Following the sudden and unexpected emergence of influenza A(H1N1)pdm09 (2009 H1N1) virus, this observational study was initiated to estimate rates of morbidity and mortality and to examine predictors of severity among participants with 2009 H1N1 infection. In 2011, as surveillance indicated that 2009 H1N1 virus was co-circulating with other seasonal influenza A and B viruses worldwide, the protocol was expanded to include other influenza A subtypes and influenza B viruses. The current version of the protocol (released in August 2013) further broadens the scope of this observational study. With the recognition that novel respiratory viruses other than novel influenza A viruses, e.g., Middle East Respiratory Syndrome Coronavirus (MERS-CoV), could become prevalent and of major public health importance, the objectives of this protocol have been expanded.

Mental health vulnerability due to stress is increased in People of African Descent (PADs) in America due to disproportionate effects of 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 PADs 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 virtual, community-based music mindfulness program on stress management in PAD community members with anxiety and depression during COVID19. 2b. Social Music Study: Investigators will assess the neural mechanisms of feelings of subjective connectedness during communal music listening and creating between dyads of subjects who are both familiar and unfamiliar with each other.

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).
