The term post-acute COVID-19 syndrome or Long COVID is a disabling syndrome that persists beyond the 3-month convalescence period after COVID-19 infections. This syndrome affects mostly women (~80%), present with chronic tachycardia and Orthostatic intolerance symptoms without any identifiable cause. In addition, non-specific symptoms such as fatigue, headache, and "brain fog", commonly described in POTS patients are also present in this novel condition, recently named post-COVID-19 tachycardia syndrome, POTS variant. Reduced Vagal activity and unresolved inflammation is post-COVID-19 POTS is hypothesized as the cause of Long COVID

The primary objective of this study is to conduct a 16-week randomized controlled trial aimed at investigating the effectiveness of the Whole-Diet Approach when following a healthy US-style diet rich in anti-inflammatory properties. The study will focus on evaluating its impact on reducing symptoms related to Post-Acute Sequelae of SARS-CoV-2 Infection (PACS) in adults aged 50 years and older. The main research questions this study aims to answer are: 1. Does adhering to a healthy US-style diet, which is abundant in anti-inflammatory properties, effectively mitigate fatigue symptoms in adults with PACS? 2. Does adhering to a healthy US-style diet, which is abundant in anti-inflammatory properties, effectively mitigate declines in muscle function and physical performance in adults with PACS? At the beginning of the study, eligible participants will be randomly assigned to either the Dietary Intervention Group, where they will receive personalized dietary plans and weekly sessions, or the Attention Control Group, where they will attend general health sessions on a weekly basis as well. This research intends to shed light on the potential benefits of the Whole-Diet Approach and its role in ameliorating PACS-related symptoms among older adults. By comparing the outcomes of the two groups, we hope to gain valuable insights into the effectiveness of this dietary intervention in improving the quality of life for individuals dealing with PACS.

Background: Respiratory viruses circulate throughout the year and around the globe. Wearable and sensor devices, like smartwatches, may be able to help monitor infectious diseases. Researchers want to use them to learn how respiratory viruses affect people in different ways. Objective: To use digital devices to collect data from participants in challenge studies that could indicate subtle changes in health during an infection that might otherwise go unnoticed. Eligibility: Healthy adults who have enrolled, were recently enrolled, or are scheduled to enroll in a challenge study. Design: Participants will stay at NIH for the duration of the challenge study (at least 9 days) and then will have outpatient follow-up visits (2-4). While at NIH, participants will wear a smartwatch at all times. It will record data like temperature, heart rate, breathing rate, and movements. Participants will have a smartphone that records at all times to listen for coughing and changes in voice. Participants will perform tasks every 4 hours during the daytime. They will record themselves coughing, breathing in deeply, and reading aloud. They will take videos of their face. They will play a game to test their reflexes and focus. They will measure their head temperature with their smartwatch. For outpatient visits, participants will use one smartphone and the smartwatch to complete the above tasks. Participants will be sent a smartwatch to wear at home at night to collect additional healthy data. Participation will last the duration of each challenge study, and may range from 10 weeks to 2 years.

The goal of this clinical trial is to test two investigational COVID-19 booster vaccines, called CoTend-s3BXBB and CoTend-BXBB, in healthy volunteers ages 40-64. The CoTend-s3BXBB vaccine includes a component called "s3", which was designed to improve the body's response to the vaccine. CoTend-BXBB is the same vaccine without s3. The main questions the study aims to answer are: 1) Is the investigational vaccine safe? 2) Does "s3" lead to bigger, broader, and longer-lasting responses to the vaccine? 5 different doses of the vaccines will be studied. Participants will receive a single dose of either CoTend-s3BXBB, CoTend-BXBB, or placebo. Participants will be monitored for side effects. Saliva, nasal, and blood samples will be collected and immune responses to the vaccine will be measured.

The 2019-2020 COVID-19 pandemic is the largest outbreak in recent history. It is not known how long after someone gets sick with COVID-19 and recovers that they can still infect other people. It is also not known how quickly people make antibodies against the virus, which help clear infection from the body. The investigators will enroll 300 people who had COVID-19 based on lab testing or confirmed exposure to participate. An additional 25 participants who have never tested positive for COVID and have not had the vaccine will be enrolled as negative controls. Participants will complete a survey at enrollment. The investigators will also collect blood, nose swab, saliva, stool, semen, and breast milk to test for the virus. The investigators will ask participants to complete a survey and give specimens up to 12 times over 24 months. This information will be used to study how long the virus can live in different parts of the body, antibody development, and post-infectious complications. The investigators hope that this information will allow medical and public health providers to make recommendations to better care for patients in the convalescent phase of COVID-19 infection.

This phase 1 clinical trial will evaluate the safety, reactogenicity, and immunogenicity of Boost-2867, given intramuscular (IM) with or without adjuvant or intranasal (IN) without adjuvant, as a booster dose to previously vaccinated healthy adults. Each of the six study sites will be assigned to enroll either only participants who will receive IM administration (3 sites) or only participants who will receive IN administration (3 sites); no site will administer both IM and IN study product administrations. Within the IM and IN Arms the cohorts will be sequentially enrolled. The study is designed as a non-randomized, open-label, dose-escalation clinical trial evaluating one dose level of Boost-2867 without adjuvant administered IM, three dose levels of Boost-2867 with adjuvant administered IM, and three dose levels of Boost-2867 without adjuvant administered IN. A sample size of 140 participants (20 participants per dose cohort) is anticipated. To evaluate for early safety signals for this first-in-human trial, study product administration of participants enrolled for IM administration and those enrolled for IN administration will proceed in a staged fashion. For Cohorts 1 (IM administration without adjuvant) and 5 (IN administration), which may be enrolled and dosed concurrently, 3 sentinel participants under 50 years of age will be enrolled in each Cohort over at least 2 days. For each of those Cohorts independently, a safety review of halting rules and clinical safety data through at least Day 8 will be conducted by the Protocol Safety Review Team (PSRT) prior to enrollment of the remainder of the cohort. Enrollment, dosing, and safety oversight for IM Cohorts 2, 3, and 4 will proceed in the same fashion as Cohort 1, except that sentinel enrollment need not be spaced over at least 2 days. Similarly, for IN Cohorts 6 and 7, enrollment and safety oversight will proceed in the same fashion as Cohort 5, except that sentinel enrollment need not be spaced over at least 2 days. The primary objectives are: 1) To evaluate the safety and reactogenicity of a single IM injection of three different antigen dose levels (5, 15, and 50 microgram) of Boost-2867 with Alhydrogel (R) (alum) and CpG 7909 adjuvants, and a single injection of 50 microgram Boost-2867 without adjuvant, in previously vaccinated healthy adults. 2) To evaluate the safety and reactogenicity of a single IN administration of three different antigen dose levels (20, 50, and 125 microgram) of Boost-2867 without adjuvant in previously vaccinated healthy adults.
