In this Phase III study, the investigators will build off of the Phase II embedded study with some adjustments to the design to address new research priorities that examine an intervention that is network informed and delivered through community health worker interactions plus digitally-delivered intervention content with the goal of increasing COVID-19 testing and vaccination. This model, if proven effective, can be scaled up to address COVID-19 and other future pandemics. The investigators will utilize the sample of intervention priority census block groups (PBGs) used in Phase II and will recruit and enroll participants not previously enrolled in either phase I or II from these PBGs using convenience sampling methods. The investigators will use a historical control group consisting of participants from our control arm in Phase II who completed both their baseline and follow-up surveys embedded in the study.

The evidence-based Concordant Care approach involves engaging in processes that: 1) validate the patient's experience, 2) develop a shared understanding of the condition, and 3) create a patient-centered, whole health-oriented action plan to manage the condition. This is consistent with published expert opinion that Concordant Care underlies patients' (and clinicians') positive experiences of care for poorly understood conditions. Despite strong evidence supporting this care approach, there are no interventions to train clinicians on practices to provide Concordant Care for Veterans with poorly understood conditions such as Long-COVID. Part 1 of the study will optimize and test if a Concordant Care training improves VA clinicians' engagement in recommended practices to provide Concordant Care (i.e., validate, shared understanding, action plan) for Veterans with Long-COVID. This study will adapt and refine Concordant Care training for Long-COVID. Part 2 of this study will determine if Concordant Care training increases clinicians' engagement in recommended practices to provide Concordant Care and will explore the effectiveness of Concordant Care on care outcomes including satisfaction, adherence to care, & disability for Veterans with Long-COVID. Veterans treated by clinicians receiving Concordant Care training will report their clinician more frequently engaged in recommended conversations (i.e., ask about Long-COVID, validate experience with Long-COVID, create a shared understanding and action plan), and Veterans will perceive greater shared understanding of Long-COVID with their clinicians than Veterans treated by clinicians in the control arm.

Plasma from patients who have recovered from coronavirus disease 2019 (COVID-19) is referred to as COVID-19 convalescent plasma (CCP), and may contain antibodies against SARS-CoV-2, the virus responsible for COVID-19. CCP infusion is being evaluated as a therapeutic or prophylactic approach in COVID-19 patients. The goal of this study is to help develop a bank of convalescent plasma in California, especially in medically underserved communities particularly affected by the disease. In parallel, CCP administered to COVID-19 patients will be collected and analyzed to determine whether the antibody profile correlates with clinical outcome. The purpose of this non-therapeutic study is to learn more about the CCP antibody profile and the effect it may have in treating COVID-19 infection. Type: Observational Start Date: Jul 2020 |

Dime La VerDAD is an innovative social media capacity-building program that empowers promotores de salud to debunk vaccine misinformation through the use of personal narratives on social media. The core of the implementation strategy consists of augmenting training and self-efficacy for natural community champions, "promotores de salud" from the Hispanic community as trusted messengers to debunk vaccination misinformation. The study will leverage existing community relationships in Chicago and a first of its kind misinformation curriculum to debunk misinformation in communities served by participating promotores de salud. Dime La VerDAD (Verify, Debunk, and Disseminate) is an innovative social media capacity-building program based on theoretical frameworks related to health communication that empowers promotores de salud to debunk vaccine misinformation through the use of personal narratives on social media. This mixed methods study will use a rigorous stepped wedge design to 1) deliver a scalable program of science communicators using an adapted curriculum grounded in infodemiology, 2) evaluate how debunking misinformation is perceived on social media, and 3) discern how use of personal narratives to enhance science communication can lead to changes in opinions and behavior (vaccination rates) about COVID and influenza vaccines among Chicago's predominantly Hispanic communities.

The purpose of this study is to understand the safety and effects of a combined influenza and COVID-19 vaccine. This combined vaccine is compared to separate vaccines for the protection against influenza and SARS-CoV-2. Influenza and COVID-19 are diseases that can spread easily from one person to another and cause body aches, fever, cough, and other symptoms. Giving both influenza and COVID-19 vaccines together against influenza and SARS-CoV-2 could provide great benefits to both patients and caregivers in terms of simple and easy care. Around 8550 participants will be assigned into 1 of 8 vaccination groups (Group A, B, C, D, E, F, G or H) by chance. Cohort 1: Approximately 450 participants will be assigned by chance to one of the following: - Group A:Influenza and COVID-19 combination A vaccine, given at the same time in one arm and placebo (an injection consisting of just salt water and no medicines in it) in the opposite arm. - Group B: COVID-19 vaccine, given at the same time to one arm and licensed influenza vaccine in the opposite arm. Cohort 2: Approximately 4500 participants will be assigned by chance to one of the following: - Group C: Influenza and COVID-19 combination B vaccine, given at the same time in one arm and placebo in the opposite arm. - Group D: COVID-19 vaccine, given at the same time in one arm and licenced influenza vaccine in the opposite arm. Cohort 3: Approximately 3600 participants will be assigned by chance to one of the following: - Group E: Influenza and COVID-19 combination B vaccine. - Group F: COVID-19 vaccine. - Group G: Licenced influenza vaccine. - Group H: Investigational influenza vaccine. All participants in cohort 1 and cohort 2 will receive 2 injections and participants in cohort 3 will receive 1 injection as per their assigned study group at Visit 1. The participants will be followed for about 6 months. During this time, researchers will assess safety and the body's reaction to the vaccination over approximately 6 months.

Background: Vaccines against SARS-CoV-2, the virus that causes COVID-19, have been highly effective against preventing severe disease. But the protective effects of these vaccines appear to wane over time. Researchers want to learn why. Objective: To learn more about how the immune system responds to vaccines against infections like SARS-CoV-2. Eligibility: Healthy adults ages 18 or older who are scheduled to receive either a new vaccine or a booster shot against SARS-COV-2 or another emerging infection. Design: Participants will be screened with a medical history and blood and urine tests. Participants will have up to 8 study visits in 1 year. Each visit should last less than 2 hours. At each visit, participants will give blood samples. Some blood samples will be used for genetic testing. They will also give updates on their health. After the first study visit, participants will receive either a first vaccination or a booster shot. They must get the vaccine in their community or workplace. They will not get the vaccine at NIH. This study currently focuses on SARS-CoV-2, but it will expand to other infectious diseases as they emerge and become the target of new vaccines. ... Type: Observational Start Date: Oct 2021 |
