Filter by:This project will build on an existing CDC funded cooperative agreement in the Dominican Republic with the Brigham and Women's Hospital (2018-2023) that includes (i) prospective COVID-19 and AFI surveillance at two health facilities and (ii) a nationally representative cross-sectional community-based serological survey of approximately 7,000 healthy adults and children targeting SARS-CoV-2 and other AFI pathogens to be conducted between April and June 2021. This linked study will establish a nested cohort of 2,000 participants enrolled in the national serological survey and prospectively monitor them for COVID-19 symptoms, conduct serial serological testing, implement molecular surveillance for SARS-CoV-2 and sequencing for variants of concern, implement and evaluate WASH mitigation measures, and monitor uptake and perceptions of COVID-19 vaccines.
This Phase 2 study design will confirm that the chosen formulation and dosing regimen of CoVLP has an acceptable immunogenicity and safety profile. Subjects will be followed for durability of the immune responses for a period of 12 months after the last vaccination.
Povidone iodine (PVP-I) is a well-known broad spectrum, resistance free antimicrobial agent that has a long history of safe and effective use. Halodine Nasal Antiseptic is formulated for topical application PVP-I to nasal passages, and has demonstrated effectiveness against SARS-COV-2 in vitro - 99.99% inactivation within 15 seconds. This study will evaluate the ability of Halodine Nasal Antiseptic to impact SARS-CoV-2 in vivo.
The current pandemic caused by the newly identified coronavirus responsible for COVID-19 is a major threat to our populations and societies. Hypothesis/Objective The acquisition of protective immunity at the level of the individual, either through vaccination or natural resolution of the infection, progressively leads at the level of the population to the reduction of the fraction of the population that can be productively infected and transmit the virus, hence, leading to the diminution of the rate of transmission, a phenomenon called herd immunity. Herd immunity was proposed as a strategy to control the infection. However, it remains difficult to model group immunity given the limited knowledge of the interaction between the host immune system with the virus, whose capacity to evolve in face of a neutralizing response is also not known. It is therefore important to acquire a better knowledge of the immunological memory that ensures the resolution of COVID-19 after SARS-CoV2 infection. Method To study single-cell B and T memory cells specific for the anti-SARS-CoV-2 response and characterize somatic mutations of immunoglobulin genes and TCR, in hospitalized and symptomatic patients and in patients cured of SARS-CoV-2.
Main goal: To generate information on the efficacy and safety of Dialyzable Leukocyte Extract (DLE) as an aid in the treatment of patients with acute respiratory infection (suspected or confirmed cases of COVID-19). Primary goal: To generate information on the efficacy of DLE as an aid in symptomatic treatment, by reducing the signs and symptoms of acute respiratory infection (suspected/confirmed cases of COVID-19). Secondary goals: 1. To evaluate clinical deterioration and respiratory alarm data. 2. To evaluate the duration of the clinical picture. 3. To explore cytokine changes associated with the therapeutic effect induced by DLE. 4. To obtain data on the safety of DLE as an aid in the symptomatic treatment of acute respiratory infection (suspected/confirmed cases of COVID-19). 5. To generate information to validate the contingency scale to assess the severity of acute respiratory disease (suspected/confirmed cases of COVID-19). Justification The systemic inflammatory response has been recognized as being responsible for COVID-19 complications. Immunomodulation strategies to control it are currently being considered, including the use of systemic steroids to down-regulate the systemic inflammatory response, the use of human immunoglobulin and even chloroquine given its anti-inflammatory and antiviral qualities; however, none of these treatments has been sufficiently studied or has shown any significant change in the clinical course of infected patients. Due to the importance of the COVID-19 pandemic and in the absence of specific treatment, it is important to implement new treatments that allow modulating the immune response, and one strategy may be the addition of DLE to symptomatic and supportive treatment. Hypotheses by goals. 1. The addition of DLE to the symptomatic treatment could decrease the severity of the clinical outcome (signs and symptoms) in individuals with an acute respiratory infection (cases suspected/confirmed by COVID-19). 2. The addition of DLE to the symptomatic treatment could decrease the clinical deterioration due to the acute respiratory infectious process (suspected/confirmed cases of COVID-19). 3. The addition of DLE to the symptomatic treatment could decrease the duration of the clinical outcome (suspected/confirmed cases of COVID-19).
