Study of Cord Blood Derived Mesenchymal Stem Cells for Treatment of Moderate, Severe or Critical Pneumonia
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.

A Vaccine Booster (GEO-CM04S1) for the Prevention of COVID-19 in Patients With Chronic Lymphocytic Leukemia
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.

SARS-CoV-2 Vaccine (GEO-CM04S1) Versus mRNA SARS-COV-2 Vaccine in Patients With Blood Cancer
This phase 2 trial studies the immune response to GEO-CM04S1 (previously designated as COH04S1) compared to standard of care (SOC) mRNA SARS-COV-2 vaccine in patients with blood cancer who have received stem cell transplant or cellular therapy. GEO-CM04S1 belongs to a category called modified vaccinia Ankara (MVA) vaccines, created from a new version of MVA, called synthetic MVA. GEO-CM04S1 works by inducing immunity (the ability to recognize and fight against an infection) to SARS-CoV-2. The immune system is stimulated to produce antibodies against SARS-CoV-2 that would block the virus from entering healthy cells. The immune system also grows new disease fighting T cells that can recognize and destroy infected cells. Giving GEO-CM04S1 after cellular therapy may work better in reducing the chances of contracting coronavirus disease 2019 (COVID-19) or developing a severe form of COVID-19 disease in patients with blood cancer compared to SOC mRNA SARS-CoV-2 vaccine.

A Trial of a Next Generation COVID-19 Vaccine Delivered by Inhaled Aerosol
The goal of this clinical trial is to study the safety of a new inhaled vaccine to prevent COVID infection and learn about the immune responses that are made in the lungs and the blood after vaccination. Participants will be randomized (like the toss of a coin) to receive the experimental vaccine or a placebo (a look-alike solution that contains no vaccine). To be in the study participants will have to have already had three doses of a messenger ribonucleic acid (mRNA) COVID vaccine and be generally healthy. Participants are given a single dose of the vaccine by breathing in a fine mist that goes directly into the lungs. During follow-up participants will: * visit the clinic for checkups and blood tests at 2, 4 and 8 weeks after vaccination * report their symptoms for 24 weeks after getting the vaccine. In some participants, the researchers will collect cells from the lung 4 weeks after vaccination (a test known as a bronchoscopy).

Send-In Sample Collection for Comprehensive Analyses of Innate and Adaptive Immune Responses During Acute COVID-19 and Convalescence
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes coronavirus disease 2019 (COVID-19). The global outbreak of COVID-19 is a major public health problem. COVID-19 causes a wide range of symptoms. These symptoms range from mild breathing problems to life-threatening problems or death. Some people have no symptoms. This study aims to learn how acute and late immune responses to COVID-19 lead to different outcomes. The immune system is the body s defense against germs, including viruses, that invade the body. Objective: To characterize the immune responses during and after SARS-CoV-2 infection and determine if there is any relationship to clinical course and outcome. Eligibility: People ages 0 99 who have confirmed or suspected SARS-CoV-2 infection, people who are not infected despite heavy exposure, and relatives of enrolled participants. Design: This is a sample collection protocol to receive send-in biological specimens for exploratory studies, including gene testing. Participants will not be seen at the NIH for study visits. Study staff will talk with participants health care providers to screen them for the study. Participants enrolled into the protocol will send samples and clinical information at least once and more often if the participant has COVID-19. All participants will provide blood samples and possibly stool. We may also ask for left over specimens from any medical procedures completed as part of medical care. The study staff will also request participants health care providers to complete a survey to collect demographic and medical data. Some of this information may need to be provided directly by the participant. Pregnant individuals are invited to participate and may be asked to give cord blood samples after delivery. Study findings that affect participants health may be shared with their health care provider. Depending on findings, participants may be contacted to take part in other NIH studies.

Evaluation of Immunologic Response Following COVID-19 Vaccination in Children, Adolescents, and Young Adults With Cancer
This study evaluates immunologic response following COVID-19 vaccination in children, adolescents, and young adults with cancer. Vaccines work by stimulating the body's immune cells to respond against a specific disease. The immune response produces protection from that disease. Effects from cancer and from treatments for cancer can reduce the body's natural disease fighting ability (called immunity). Factors such as vaccine type, timing of vaccine dosing related to treatment for cancer and number of vaccine doses or "boosts" (extra vaccine shots) may strengthen or diminish the body's protective immune response. This study may help researchers learn more about how the body's immune system responds to the COVID-19 vaccine when the vaccination is given during or after cancer treatment.

A Study on the Effects in Healthy People of a New Drug Called PDI204 for Treating COVID-19
The goal of this clinical trial is to learn if a new drug called PDI204, developed for treating or preventing COVID-19, is safe and well-tolerated in healthy volunteers. This is a first-in-human study. The main questions it aims to answer are: Is PDI204 safe and well-tolerated in healthy people? How long for and how does the body interact with PDI204? Researchers will compare side effects in people who receive PDI204 and in those who receive a placebo (a look-alike substance that contains no drug) to see if and how many side-effects there are with PDI204. Researchers will also measure how long PDI204 can be detected in the blood. Participants will be asked to receive a single dose of PDI204. Participants will have to stay in the clinical center for the day of receiving the dose of PDI204 and will be discharged the next day. Participants will then need to come back to the clinical center for study visits on days 3, 5, 7 (+/-1), 15 (+/-1), 30 (+/-3), 60 (+/-3) and 90 (+/-7).

A Study to Learn About How Well Yearly Updates to the COVID-19 Vaccine Work to Protect People From COVID-19 and How Much Money People Spend on Healthcare for COVID-19
The purpose of this study is to learn about how well the yearly updates to the COVID-19 vaccine work in adults (age 18 years and above) with a healthy immune system (the body's cells, tissues and organs that work together to protect your body) and in children (age 6 months to 17 years). This study will use a collection of insurance claims and state vaccine registry data called HealthVerity. All patient names and other identifying information is removed. This study will include children who: * Are 6 months of age to 17 years of age * Are enrolled for at least 6 months in a row in a health insurance plan that provides data to HealthVerity * Are enrolled for at least 6 months in a row in a prescription drug insurance plan that provides data to HealthVerity * Live in the same US state for 6 months in a row * Live in a US state that requires COVID-19 vaccine reporting and provides all vaccine history data to HealthVerity * Do not have mismatches in sex and/or year of birth between any of the available datasets * Do not have records of having had COVID-19 and/or any COVID-19 vaccine in the 90 days before the start of the study This study will include adults who: * Are 18 years of age and older * Are enrolled for at least 12 months in a row in a health insurance plan that provides data to HealthVerity * Are enrolled for at least 12 months in a row in a prescription drug insurance plan that provides data to HealthVerity * Have lived in the same US state for at least 12 months * Live in a US state that requires COVID-19 reporting and provides all vaccine history data to HealthVerity * Do not have mismatches in sex and/or year of birth between any of the available datasets * Do not have records of having had COVID-19 and/or any COVID-19 vaccine in the 90 days before the start of the study This study will use the data that has already been collected, and no treatment or vaccine will be given in the study. People who match the information above will be followed in the HealthVerity database for up to 6 months following the first day that a new COVID-19 vaccine is available. This information will be reviewed to see if any of the following happen: * they had a COVID-19 vaccine * they're diagnosed with COVID-19 in a doctor's office * they visit the emergency department for COVID-19 * they visit urgent care for COVID-19 * they are hospitalized for COVID-19 The experiences of people who received a COVID-19 vaccine will be compared to the experiences of people who did not receive the vaccine. This will help to understand how well the Pfizer-BioNTech COVID-19 vaccine works at stopping COVID-19.

Well-Being and Health-Related Quality of Life in Melanoma Patients During COVID-19 Pandemic
The primary purpose of this study is to gain an understanding of how experiences during the COVID-19 pandemic, regardless of COVID-19 status, may have impacted multiple domains of health-related quality of life and other areas such as COVID-19 specific psychological distress, and disruptions to health care, finances and social interactions. We will also evaluate the extent to which resiliency factors such as social support, perceived benefits under times of stress, and ability to manage stress may buffer associations between COVID-19 experiences and HRQoL. To meet these objectives, we have developed a 10-minute questionnaire that taps into these areas and is based on prior work addressing concerns of other pandemics or national crises. Participants will have previously consented to protocol PA15-0336 and have provided prior lifestyle data. This will allow us to connect the COVID-19 survey data with prior existing data.

Integrated Mindfulness-based Health Qigong Intervention for COVID-19 Survivors and Caregivers
COVID-19-related depression, anxiety, and stigma are expected to have short-term and long-term adverse impacts on mental health, help seeking and preventive behaviours in affected individuals, including care providers and the general population. Health qigong (HQ), a form of traditional Chinese martial arts with emphasis placed on the body movement and status of mind, has been demonstrated to enhance both physical and mental health. Mindfulness-based interventions (MBIs), another mind-body treatment, have become increasingly popular for treating a number of health problems. This study proposes an integrated intervention that combines the effects of HQ and MBIs (iMBHQ) to improve the mental wellbeing of COVID-19 survivors, caregivers including healthcare providers and family members as well as the general public in the community.
