The main purposes of this research study are to measure the safety (whether it causes any side effects), tolerability (if it does cause any side effects, how well your body is able to handle them), and reactions, both local at the injection site and systemic, that may occur in the body after receiving VYD2311, or a COVID-19 vaccine, or a combination of VYD2311 and a COVID-19 vaccine in healthy participants. This research study will measure the amount of serum virus neutralizing antibodies produced in the blood (antibodies that block a virus from infecting cells) and pharmacokinetics of VYD2311 compared to a COVID-19 vaccine, when each is administered alone or concurrently. Pharmacokinetics is the study of how a drug moves through the body, including how it is absorbed (taken into the body), distributed (spread throughout the body), metabolized (broken down in the body), and eliminated (removed from the body), and how the body affects the drug.

COVID-19 is a systemic inflammatory disease involving many organs including the lungs, vascular system liver and myocardium that lead to severe pathologies. Patients with severe cardiopulmonary symptoms usually require weeks to months to fully recover. Studies of clinical and subclinical impairments of COVID-19 patients are important for medical practice and public health as well as providing pathogenic insight to the viral infection and secondary immune response. Chronic damage of vital organs and systems, and the potential long-term effects is of serious concern. In this study the investigators plan to quantify and characterize chronic consequences of COVID-19 in individuals who receive similar medical care related to disease severity and duration in a single health care system. Using state-of-the-art Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) technology, we will study the pathology in major organ systems in comparison to matched controls. The results of this study may facilitate measures to prevent, detect, and manage complications from COVID-19 infections.

Background: SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from an acute COVID-19 infection may continue to have symptoms that persist for months or years. These can include neurological symptoms, such as headaches, loss of taste or smell, dizziness, or trouble walking. Pembrolizumab is a drug approved to treat certain cancers. Researchers think this drug might reduce long-term neurologic symptoms after a COVID-19 infection. Objective: To test pembrolizumab in people with ongoing neurologic symptoms of COVID-19. Eligibility: People aged 18 years or older who had COVID-19 at least 6 months ago and have ongoing neurologic symptoms. Design: Participants will have 7 clinic visits in 7 months. Participants will be screened. They will have a physical exam with blood tests. Swabs will be used to collect cells from inside the mouth and nose. They may opt to have an imaging scan. Participants will also have other tests before they are given the study drug. These include eye and skin exams; tests of their memory and thinking; and tests of involuntary body functions, such as heart rate, blood pressure, sweating, and digestion. Their grip strength and walking pace will be measured. They will wear a heart rate monitor for 24 hours. They will wear devices on a wrist and thigh to measure activity for 10 days. Participants will have a lumbar puncture (spinal tap): A thin needle will be inserted into their lower back to draw out a sample of the fluid around their spinal cord. Pembrolizumab is given through a needle inserted into a vein. Participants will receive 1 dose of the drug. Participants will have 4 follow-up visits over 6 months. Tests may be repeated during these visits.

This research is being done to collect preliminary data on the potential of computerized "brain-training" exercises for treating Long COVID symptoms in older adults. The investigators hypothesize that computerized brain-training will be an acceptable and feasible intervention for treating Long COVID symptoms in older adults. The investigators also expect to provide initial evidence that computerized brain-training has potential for improving thinking, mood, and other aspects of everyday functioning in older adults with Long COVID.

The overall goal of this project is to advance the understanding of underlying mechanisms impacting performance fatigability and perceived fatigability in Veterans with post-COVID-19 fatigue and explore the safety and feasibility of a home-based "minimal-dose" resistance exercise program in this population. The central hypothesis is that declines in force capacity, skeletal muscle oxygen extraction, and affective responses to physical activity offer potential mechanisms through which fatigability is increased in Veterans with post-COVID-19 fatigue. Moreover, home-based resistance exercise delivered remotely may provide a safe and feasibility treatment option for targeting neuromuscular and neurobehavioral factors influencing fatigability severity in this population.

This study is testing a new brief mindfulness practice for people suffering from long COVID-19 symptoms. People suffering from long COVID are particularly vulnerable to negative emotions, as they must also cope with the long-term uncertainty of physical and psychological stress beyond the acute infection. The goal of the study is to measure the ability of a brief mindfulness practice to promote a sense of well-being in people suffering from long COVID.

The study investigates how the COVID-19 pandemic has impacted the psychological, financial, physical, and social well-being of adolescent and young adult (AYA) cancer patients and survivors. AYA cancer survivors have inferior long-term survival compared to the general population, and the negative impact of the global COVID-19 pandemic may be even higher in this vulnerable group. The information gained from this study may provide an opportunity to determine the self-reported COVID-19 specific psychological distress in AYA cancer survivors, and may lead to the development of a targeted intervention to improve physical and psychosocial health for AYA cancer patients and survivors.
