The overarching goal of this project is to confirm or refute the role of passive immunization as a safe and efficacious therapy in preventing the progression from mild to severe/critical COVID-19 illness and to understand the immunologic kinetics of anti-SARS-CoV-2 antibodies after passive immunization.The primary objective is to determine the efficacy and safety of a single dose of convalescent plasma (CP) for preventing the progression from mild to severe COVID-19 illness. The secondary objective is to characterize the immunologic response to CP administration. This study will enroll adults presenting to the emergency department (ED) with mild, symptomatic, laboratory-confirmed COVID-19 illness, who are at high risk for progression to severe/critical illness, but who are clinically stable for outpatient management at randomization.

Background: The indirect effects of the COVID-19 pandemic on mental health are of increasing concern. Perceived stress can lead to binge eating and weight gain. Researchers want to learn more about the relationship between eating behavior and the pandemic. Objective: To study how the stress of the COVID-19 pandemic is affecting eating behaviors and weight. Eligibility: English-speaking adults ages 18 and older who have access to a computer or smartphone connected to the internet. Design: This is an online study. Participants will answer surveys through the study website. Participants will complete a one-time survey. It will ask about their experiences throughout the COVID-19 pandemic, their socioeconomic standing, their mental and physical health, and their eating habits. They will have the option to repeat the survey once a month for the next 12 months. This will show changes in their thoughts and behaviors over time. They will provide their email address to get survey links. Participants will also have the option to complete a 2-minute survey on their smartphone. They will complete the survey daily for 7 days in a row. It will ask about their stress and eating behavior in real time, in their home environment. They will provide their phone number to get survey links via text message. If a participant has taken part in a previous NIH study on the Phoenix AZ campus, they will be asked to share their first and last name, date of birth, and email address. This information will be used to connect data from this study to their past data. Participation is typically 25 minutes but may last up to 1 year. ***To participate in this study go to the REDCap study link: https://redcap.link/nihcovidstudy.***...

Background: People who are recovering from COVID-19 may continue to have problems that affect their daily life. For instance, they might feel overly tired. Researchers want to learn if exercise can help people recover after COVID-19 infection. Objective: To study if participation in a rehabilitation exercise program can help people recovering from COVID-19. Eligibility: Adults ages 18-80 with a lab-confirmed SARS-CoV2 infection (the virus that causes COVID-19), and are still having some symptoms. Design: Participants will have a medical history and physical exam. They will give blood and urine samples. They will have tests to measure heart and lung function. Their blood vessels will be assessed. Participants will have a computed tomography scan of the body. They will have an ultrasound of the muscles in their arms, legs, and chest. Participants will take a 6-minute walk test. They will take other balance and movement tests. Participants will walk on a treadmill while hooked up to a monitor. Then they will be interviewed. It will be audio-recorded. Participants will complete surveys about their symptoms and daily activities. Participants will take a smell test. For this, they will identify different smells. They will also have memory, attention, and mental functioning tests. Participants will wear an activity monitor on their wrist 24 hours a day. They will exercise 3 times a week for 10 weeks by moving vigorously on a track or treadmill for 30 minutes. They will attend education classes once a week for 10 weeks. Participants will be contacted by phone or email every 3 months for 1 year after they complete the exercise part of the study. They will wear an activity monitor for up to 2 weeks.

The purpose of this clinical trial is to learn about the safety, extent of the side effects, and immune responses of the study vaccine (called variant-adapted BNT162b2 RNA-based vaccine) in healthy children. The trial is divided into 5 individual studies or substudies based on age group and prior history of COVID-19 vaccinations. All participants in each of the 5 sub-studies will receive study vaccine as a shot depending on what group they are in. - Substudy A design: Phase 1 includes participants 6 months through less than 4 years 3 months of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naïve) and will receive 3 doses of study vaccine as their initial series, followed by a fourth dose of study vaccine. Phase 2/3 includes participants 6 months through less than 5 years of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naive) and will receive 1, 2, or 3 doses of study vaccine, depending on what group they are in. - Substudy B design: includes participants 6 months through less than 5 years of age who have either received 2 or 3 prior doses of BNT162b2 and will receive study vaccine as their third or fourth dose. - Substudy C design: Phase 1 includes participants 6 months through less than 5 years of age who have received 3 prior doses of BNT162b2 and will receive study vaccine as their fourth dose. - Substudy D design: includes participants 5 through less than12 years of age who have received 2 or 3 prior doses of BNT162b2 and will receive study vaccine as their third or fourth dose. - Substudy E design: includes participants 2 through less than 12 years of age who have not received a previous coronavirus vaccination (COVID-19 vaccine naive) and will receive a single dose of study vaccine.

The purpose of this initial study is to evaluate a new form of cognitive rehabilitation therapy for improving your ability to think, particularly how rapidly you process information that you receive from your senses, e.g., sight, hearing, and smell. The study will also test how often and how well you carry out tasks that rely on thinking in your daily life. You will be randomly assigned to receive the new therapy soon or about three months later. In other words, your treatment schedule will be determined by chance. The new therapy involves intensive, repetitive cognitive exercises (up to 3.5hr/day for 10 consecutive weekdays) with rest periods interspersed as needed.

Background: Vaccines help prevent disease by causing the body to have an immune response. Many parts of this response happen in the blood. This response happens over days and weeks after getting the vaccine. Researchers want to how the blood changes over time in response to vaccines. They want to find out why vaccines work better for some people than for others. This could help make more effective vaccines. Objective: To learn about how the body responds to vaccines. Eligibility: Healthy people ages 18 and older Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. Participants will have 9 visits over 6 months. All visits will include blood tests and a physical exam. Participants will have the first visit 1 week before they get the vaccine. Participants will get the flu vaccine at the second visit. The vaccine will be injected into the muscle of the upper arm with a needle. They will be watched for side effects for 15 minutes. Participants will have the next 2 visits exactly 1 day and 1 week after they get the vaccine. They will have the other 5 visits about 14, 28, 70, and 100 days after they get the vaccine. Participants will take email questionnaires about whether they had any side effects. Participants may have optional extra study visits. These will be no more than once a month for up to 1 year after they get the vaccine. Optionally, they can also repeat the study each year through the 2023 - 2024 flu season

Olfactory dysfunction is a defining symptom of COVID-19 infection. As the number of total, confirmed COVID-19 cases approached 19 million in the United States, it is estimated that there will be 250,000 to 500,000 new cases of chronically diminished smell (hyposmia) and loss of smell (anosmia) this year. Olfactory dysfunction is proposed to worsen numerous common co-morbidities in patients and has been shown to lead to a decreased quality of life. There are very few effective treatments for hyposmia or anosmia, and there is no gold standard of treatment. One proposed treatment option is smell training, which has shown promising yet variable results in a multitude of studies. It garners its theoretical basis from the high degree of neuroplasticity within the olfactory system, both peripherally and centrally. However, due to a relative inadequacy of proper studies on olfactory training, it is unknown what the most efficacious method in which to undergo the training is. This study proposes two novel procedural modifications to smell training in an attempt to enhance its efficacy. The investigators propose using a bimodal visual-olfactory approach, rather than relying on olfaction alone, during smell training, as well as using patient-preferred scents in the training that are identified as important by the study participant, rather than pre-determined scents with inadequate scientific backing. The investigators hypothesize that by utilizing bimodal visual-olfactory training and patient-selected scents, the olfactory training will be more efficacious and more motivating for participants.
