The first aim of this study is to determine the feasibility of delivering CO-OP remotely to individuals experiencing cognitive impairments that limit everyday activities in post-COVID-19 syndrome (PCS). The second aim of this study is to assess the effect of CO-OP on activity performance, subjective and objective cognition, and quality of life in a sample of individuals with PCS. The research team hypothesizes that effect size estimations will indicate that CO-OP will have a greater positive effect, compared to an inactive control group, on activity performance, subjective and objective cognition, and quality of life in a sample of individuals who self-report PCS and cognitive impairment.

The purpose of the study is three-fold. The primary aim is to identify the proportion of Long-Haul COVID (LHC) and non-LHC volunteers with relevant symptoms actually have postural orthostatic tachycardia syndrome (POTS). The second is to determine benefit of ivabradine treatment. Ivabradine is a drug approved to treat tachycardia in persons with heart failure. The third is to characterize risk factors and outcomes among volunteers with and without LHC. This will include comparison with COVID-19-positive individuals who did not develop long-COVID symptoms. The study will improve basic and applied knowledge of LHC and its associated cardiovascular and autonomic consequences. Cellular and molecular characterization of LHC and non-LHC participants will be performed with a nested clinical trial for Ivabradine responsiveness on reduction of tachycardia. It is hoped that a greater understanding of LHC, and related autonomic dysfunction in particular will help to identify treatment paradigms and therapeutic targets for improving recovery and enhancing health for those affected.

COVID-19 testing is essential to controlling the COVID-19 pandemic to break transmission chains and reduce community transmission. However, Black and Latino/Hispanic populations in lower status frontline essential occupations such as food preparation, retail, building maintenance, personal services, and in-home health care have serious barriers to COVID-19 testing and, therefore, insufficient testing rates. The proposed study will use the multiphase optimization strategy framework to address the problem of low COVID-19 testing rates for this population: We will test the effects of four distinct candidate intervention components and then create an efficient multicomponent made up of the most effective combination of the components that can be rapidly scaled up in community settings to boost COVID-19 testing rates.

This is a multicenter, US-only, phase 1, open-label, dose escalation, non-randomized study of the safety, tolerability, and immunogenicity of investigational ChAd and SAM SARS-CoV-2 vaccines in healthy adult subjects. Homologous and heterologous prime-boost vaccination schedules (Stage 1), as well as boost(s) after receipt of COVID-19 EUA/licensed vaccines (Stage 2) will be examined. Subjects' willingness to receive ChAd vaccines will be assessed and documented at the time of informed consent and considered to determine group assignments. This phase 1 study will enroll 17 Stage 1 and up to 118 Stage 2 subjects. Eligible subjects will be enrolled in different groups based on their age (18-60 years old and >60 years old) and their EUA/licensed COVID-19 vaccination status. A sentinel approach with 72-hour (Stage 1, and Stage 2, Groups 5, 6, 8-10, 12, 13-15) or 7-day observation times (Groups 7 and 11) will be used, before recruiting the remainder of each dose escalation group. Decisions about dose escalation will be determined by the SSC with consultation with the DSMB as needed after all subjects in each group have been observed through Day 8 post first study vaccination. All subjects will be followed through 12 months after their last study vaccination. Vaccinated subjects will be carefully monitored for exposure and infection to SARS-CoV-2 throughout the study. Escalation to the highest dose (10 µg) of SAM-S-TCE in younger subjects will proceed only following safety assessments of the 10 µg dose in older subjects for a period of 28 days post-vaccination. In addition, the dosage of SAM-S-TCE given as a double boost to subjects previously vaccinated with the Johnson & Johnson/Janssen Ad26 COVID-19 EUA/licensed vaccine in Groups 8A, 8B, and 12A, 12B will be determined based on the dose escalation reactogenicity and immunogenicity results in Groups 5-7 and 9-11, respectively. After protocol version 9.0 was implemented, it was decided not to enroll subjects into Groups 7 and 8 because of competing priorities and predicted difficulties enrolling into these two groups. The primary objectives of this study are 1) To assess the safety and tolerability of different doses of ChAd-S or ChAd-S-TCE, and SAM-S or SAM-S-TCE when administered as prime-boost in healthy naïve adult subjects, 2) To assess the safety and tolerability of different doses of ChAd-S or ChAd-S-TCE, and SAM-S or SAM-S-TCE when administered as first or second boost in healthy adult subjects previously vaccinated with an mRNA or adenoviral-vectored COVID-19 EUA/licensed vaccine.

Background: Middle East Respiratory Syndrome (MERS) is a newly discovered contagious and sometimes fatal respiratory virus. People often get MERS through close contact with an infected person. Scientists are worried that MERS may spread and cause more infections. There are no vaccines or treatments for MERS right now. Researchers think a new therapy called SAB-301 may be able to help. Antibodies are proteins the body makes to attack viruses. SAB-301 is made of antibodies made in cows to fight MERS. The antibodies are collected from plasma, the liquid part of cow blood. Objective: To evaluate the safety and tolerability of SAB-301 in healthy adults. Eligibility: Healthy people ages 18 60 who: Do not have chronic medical problems Do not take any medications (exceptions are acetaminophen, ibuprofen, vitamins, seasonal allergy meds and oral contraception) Do not have allergies to beef products Agree to use two forms of contraception while on study (both men and women) Design: Participants will be screened with: Medical history Physical examination Blood and urine tests Participants will have a return visit. They will have a physical exam and blood tests. They will be randomly assigned to receive either SAB-301 or a placebo which is given by infusion through an arm vein over 1 3 hours. They will be monitored at the clinic for 6 hours after the infusion. They will have additional blood draws. Participants will have 2-hour visits 1, 3, 7, 21, 42, and 90 days after the infusion. At each visit they will be evaluated and have blood and urine tests.

Background: COVID-19 is a disease caused by the SARS-CoV-2 virus. It infects the respiratory tract. Some people who get COVID-19 have only mild symptoms. But for others, infection leads to pneumonia, respiratory failure, and, in some cases, death. Researchers want to learn more about any effects that may persist after people recover from COVID-19. Objective: To learn about any long-term medical problems that people who have recovered from COVID-19 might have, and whether they develop an immune response to SARS-CoV-2 that provides protection against reinfection. Eligibility: People age 18 and older who have recovered from documented COVID-19 or were in close contact with someone who had COVID-19 but did not get the infection Design: Participants will be screened over 2 visits. During visit 1, they will answer questions about any symptoms they are having and will be tested for SARS-CoV-2 infection which will involve a nasal swab sample or other FDA approved test. If the test is negative, they will proceed to the second visit, which will include: Physical examination Medical history Mental health interview (which may be recorded if the participant agrees) Chest x-ray (for recovered COVID-19 participants only) Blood and urine tests Pregnancy test (if needed) Lung function test (for recovered COVID-19 participants only) 6-minute walk test (for recovered COVID-19 participants only) Questionnaires about their general and mental health Leukapheresis to collect white blood cells (optional). Participants will be put into 1 of 2 groups: the COVID-19 group or the close contact group. Participants will have study visits every 6 months for 3 years. They will repeat some of the screening tests. Participants in the COVID-19 group may have visits more often if they develop symptoms that suggest re-infection with SARS-CoV-2.
