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.

This Phase 1 clinical trial will evaluate the safety, reactogenicity, and immunogenicity of PepGNP-COVID19, a synthetic nanoparticle-based, T cell-priming peptide vaccine against SARS-CoV-2, when administered as a booster dose in healthy adults. PepGNP-COVID19 is designed to induce broad and durable T cell-mediated immune responses by delivering conserved SARS-CoV-2 peptides covalently bound to carbohydrate-coated gold nanoparticles, with the goal of enhancing tissue-resident cytotoxic T lymphocytes in the respiratory tract and reducing the need for frequent antigen updates. This randomized, participant-blinded, dose-ranging, multi-site trial will enroll 60 healthy adults aged 18-64 years, with a target of 8 of 20 participants in each cohort being > / = 50 years of age. Participants will receive a single intradermal injection of PepGNP-COVID19 at one of three dosage levels (0.83 nmol, 2.5 nmol, or 7.5 nmol in a volume of 0.05 mL). The primary objective is to evaluate the safety, reactogenicity, and tolerability of a single intradermal dose of PepGNP-COVID19 at three dosage levels in previously vaccinated healthy adults.

Vaccinations are among the most successful and critical public health interventions. Despite the enormous protection that vaccines provide to public health, both delays and refusals of vaccines (vaccine hesitancy) are on the rise. Given that low vaccination rates present both an individual and community risk, it is critical that measures are taken to increase vaccination uptake in both rural and urban counties in New York. Wastewater surveillance of SARS-CoV-2 has been shown to be a leading indicator of pending surges. This study will examine whether a communications campaign based upon SARS-CoV-2 wastewater surveillance data can increase COVID-19 vaccine uptake. Forty counties have been selected for the communication campaign (20 in the treatment group and 20 in the control group). A difference-in-differences method will be applied to assess the impact of the communications campaign on vaccine uptake, which observes the outcomes between a control and treatment group over pre- and post-intervention time periods. The communications campaign will be evaluated using the change in vaccination status of residents of the treatment and control counties. Outcomes will also be compared between demographic groups including race and ethnicity because of differences in vaccination rates that have been already observed. We hypothesize that information regarding COVID-19 provided by wastewater surveillance that is geographically based and more local to communities will increase COVID-19 vaccine uptake. This theory of local information having an impact on health behavior is a novel application of the health belief model to increase vaccine uptake.

An increased risk of both venous and arterial thromboembolism was noted in reports from SARS-CoV-2-infected patients in China and has been confirmed in autopsy findings from patients who experienced sudden death. Myeloproliferative Neoplasms (MPNs), which encompass polycythemia vera, essential thrombocythemia and primary myelofibrosis, are thrombophilic disorders with a natural propensity to thrombosis that is fuelled by the intrinsic activation of inflammatory cytokines. It therefore follows that an underlying diagnosis of MPN may increase the risk of worse clinical outcomes and death during periods of active Covid-19 disease. This ambispective, observational study aims to elucidate the key factors which affect the clinical course of patients with MPN who develop Covid-19 disease.

Background: The COVID-19 pandemic has challenged the health systems worldwide. Many tools have been developed in response to the pandemic, but there is no current way to quickly screen multiple people for the disease. Research has shown that people with COVID-19 have higher levels of some proteins involved in the immune response and inflammation. These proteins can be detected in sweat using a special camera. Researchers want to see if analysis of sweat from fingerprints could be used to detect COVID-19 infection in people. Objective: To test a new technology to detect COVID-19 infection based on an analysis of sweat from fingerprints. Eligibility: Adults ages 18 and older who tested positive or negative for COVID-19 within the last 7 days. Design: Participants will visit the NIH Clinical Center for one day within 7 days from COVID-19 testing. The visit will last for 3 to 4 hours. Participants who show symptoms for COVID-19 with a positive test will give blood samples to correlate with the sweat markers. About 1/2 tablespoon of blood will be drawn. For sweat markers, 10 fingers will be imaged by a camera using a touchless system. This will be repeated 3 times. It will take about 15 minutes. Participants will use the device. They will get instructions and watch a short video on how to use the device.
