The purpose of this study is to evaluate the antibody response, safety and reactogenicity of a third dose Covid-19 (recombinante) vaccine, 6 months after a two-dose vaccine schedule using the same vaccine in all doses.
The goal of this research is to increase COVID-19 vaccine acceptance and uptake in vulnerable populations whose primary (and often only) health care access occurs in emergency departments (ED Usual Source of Care Patients). Toward this goal, the investigators will conduct one on one interviews and focus groups with ED Usual Source of Care Patients and community partners and produce trusted messaging informational platforms (PROmotion of COvid-19 VA(X)ccination in the Emergency Department - PROCOVAXED) that will address barriers to COVID-19 vaccination, especially vaccine hesitancy. The investigators will then conduct a cluster-randomized, controlled trial of PROCOVAXED platforms in six EDs to determine whether their implementation is associated with greater COVID-19 vaccine acceptance and uptake in ED Usual Source of Care Patients.
This study will assess heterologous prime-boost-boost vaccine regimens in comparison with an homologous regimen in order to compare short and long-term immunogenicity of different COVID-19 vaccine combinations against the ancestral SARS-CoV-2 as well as different variants of concern (VOCs). Hypothesis: One or more heterologous prime-boost-boost COVID-19 vaccine combinations will produce humoral and cellular immunity that is non-inferior to an homologous prime-boost-boost vaccination against wildtype SARS-CoV-2 and/or 1≥ VOC.
The primary objectives of this open-label trial were to evaluate the safety and pharmacokinetics (PK) of Anti-SARS-CoV-2 Immunoglobulin (Human) Investigational Product (COVID-HIG) administered intramuscularly (IM), subcutaneously (SC), or intravenously (IV) as a single dose in healthy adults 18-59 years of age with body mass index ≤35 kg/m^2. Prior studies examined IV administration, and the secondary objective of the present study was to compare PK among the three administration routes. No placebo group was included in the phase 1 randomized design. The exploratory objective was to evaluate disease severity in participants that became positive for SARS-CoV-2.
This is an open label, phase I dose-escalation study to evaluate the safety of coronavirus-specific T cell (CST) therapy for prevention of SARS-CoV-2 infection in immunocompromised patients following hematopoietic stem cell transplantation (HSCT). Participants will receive donor-derived CSTs for prevention of SARS-CoV-2 infection after HSCT (≥28 days and <4 months after HSCT). In this dose escalation trial, three doses (1x107/m2, 2x107/m2, and 4x107/m2) will be tested for safety, with study arms for adult (≥18 years of age and <80 years) HSCT recipients (Arm A) and pediatric (≥12 years of age and <18 years) HSCT recipients (Arm B), and defined dose escalations in each study arm. The study agent will be assessed for safety (stopping rules defined) and antiviral activity.
The objective of the study is to determine the usability of the GlowTest COVID-19 Antigen Home Test in a simulated home use environment. This is an open label study to evaluate the usability of the GlowTest COVID-19 Antigen Home Test using information from the Quick Reference Instructions and website.
The purpose of this study is to assess the antibody response to COVID-19 vaccination in a cohort of patients with sickle cell disease (SCD) and to assess vaccine and SCD related complications around the time of vaccination.
This study aims to assess the impact of brief digitally delivered breathing practice and guided meditation on post-Covid physical and mental symptoms in Long Covid Patients.
To asses impact of the COVID-19 infection during Pregnancy on maternal and fetal outcome in relation to gestational age.
