Filter by:The study is a multicenter, randomized, double-blind, placebo-controlled efficacy, safety Phase III clinical trial designed to evaluate the efficacy and safety of WPV01 in patients with mild/moderate COVID-19.
It is a retrospective cohort study aiming to describe the characteristics, management and prognosis of vaccinated patients hospitalized in the intensive care unit (ICU), in comparison with non-vaccinated patients.
The goal of this clinical trial is to compare different Coronavirus Disease 2019 (COVID-19) vaccination schedules in healthy adults that have not yet been exposed to SARS-CoV-2, the virus causing COVID-19. The main questions it aims to answer are: 1. Is it possible to adapt COVID-19 vaccination schedules while maintaining an adequate humoral immune response? 2. Is it possible to adapt COVID-19 vaccination schedules while maintaining an acceptable safety profile? Participants will be vaccinated twice with a COVID-19 vaccine (on day 0, and on day 28 or 84). After each vaccination, they will collect information about adverse events in a diary for 14 days. Information about the occurrence of events such as hospitalizations and infections with SARS-CoV-2 will be collected by the investigator for up to 364 days after the first vaccination. Blood samples will be taken on different timepoints and used to assess immunity against SARS-CoV-2. Researchers will compare 8 vaccination schedules to see if the immune response and safety profile is similar. Each participant will receive 1 of the following 8 vaccine schedules: - BNT162b2 (30µg) on day 0, followed by BNT162b2 (30µg) on day 28 - BNT162b2 (20µg) on day 0, followed by BNT162b2 (20µg) on day 28 - BNT162b2 (30µg) on day 0, followed by BNT162b2 (30µg) on day 84 - BNT162b2 (30µg) on day 0, followed by mRNA-1273 (100µg) on day 28 - BNT162b2 (30µg) on day 0, followed by ChAdOx1-S [recombinant] on day 28 - BNT162b2 (6µg, intradermal administration) on day 0, followed by BNT162b2 (6µg, intradermal administration) on day 28 - mRNA-1273 (100µg) on day 0, followed by mRNA-1273 (100µg) on day 28 - mRNA-1273 (50µg) on day 0, followed by mRNA-1273 (50µg) on day 28
This study aimed to examine whether wearing masks by healthy individuals during the Covid-19 pandemic created an environment for Demodex mites, by comparing it with the control group. In order to detect the presence of Demodex mites, standard superficial skin biopsy (SSSB) was applied to the face
The aim of this observational study was to develop, with the intended users, an epidemic surveillance and response system that will be effective, sensitive, coordinated and appropriate. The STREESCO project aims to - Implement active epidemiological surveillance of suspected cases in Benin at strategic sites in accordance with the World Health Organization (WHO) protocol, in support of the national strategy for responding to the CoVID-19 virus. - To strengthen this national strategy by developing a clinico-epidemiological surveillance system in remote areas of Benin (health centre approach) and Burkina Faso (population survey approach). - To gain a better understanding of the dynamics of the epidemic and its parameters in Africa thanks to a modern biostatistical and geo-epidemiological analysis of the data collected as part of this project.
The coronavirus disease 2019 (COVID-19) pandemic was caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus. In this study, we aim to evaluate how strong and how long are individuals in Austria after vaccination and/or infection with SARS-CoV-2 protected against COVID-19 disease. In this project, we will analyze national health data from all inhabitants of Austria (about 9 million persons) during the COVID-19 pandemic. The population of Austria will be stratified into different groups according to previous vaccinations against SARS-CoV-2 and previous SARS-CoV-2 infections. We primarily evaluate how strong and how long after vaccination against SARS-CoV-2 and/or infection with SARS-CoV-2, the risk for COVID-19 deaths is reduced or altered as compared to less vaccinated and/or infected persons. As secondary study aims, we perform such analyses also for SARS-CoV-2 infections, hospitalizations and intensive care unit (ICU) stays, with or due to SARS-CoV-2. These analyses will be performed during different time periods of the COVID-19 pandemic, and we will also perform various subgroup analyses as for example according to age and gender. Given that antibodies against SARS-CoV-2 are usually detected after vaccination and/or infection, we will use such antibody data from blood donors in Tyrol, to elucidate how well the national health data on SARS-CoV-2 infections and vaccinations match with the respective antibody data, and how well these antibody data indicate risk of COVID-19 deaths and infections. We will calculate the probability of dying due to a SARS-CoV-2 infection (case/infection fatality rate) for different times of the COVID-19 pandemic, in order to document the health threat due to SARS-CoV-2. Based on all these data, we will calculate how many persons have to be vaccinated against SARS-CoV-2 to prevent one COVID-19 death at different times during this COVID-19 pandemic. We will consider the respective COVID-19 policies such as mask mandates, lock-downs, SARS-CoV-2 test mandates in our analyses and will evaluate the impact of these policies on COVID-19 deaths and diseases. In addition, we will evaluate data on total mortality according to the number of SARS-CoV-2 vaccinations and/or infections, and we will aim to collaborate with other research groups in order to extend our analyses. In conclusion, the results of this study should provide an overview on the COVID-19 pandemic with respect to protection conferred by vaccinations and previous SARS-CoV-2 infections, as well as the health threat of SARS-CoV-2, in order to provide knowledge for future COVID-19 policy and future pandemics.

This is an observational, cohort study that will use secondary data to describe the baseline demographics and clinical characteristics in patients who received EVUSHELD as PrEP against SARS-CoV-2 infection/COVID-19 in Japan. All patients who have a record of administration of EVUSHELD in the database will be included in the study. The index date will be defined as the date of first EVUSHELD administration in the database (Day 0) and the patients will be followed up to 6 months after the index date (Day 1 to 180). The look back period is defined as the 12-month period prior to index date (Day -360 to -1). The exposure of interest will be defined as the administration of EVUSHELD for use as PrEP against COVID-19. As the result of feasibility assessment, sample size of the study expected to be approximately 280.
The purpose of this study is to assess the extent to which LDL report increased adherence with COVID 19 mitigation practices 1 month post intervention.
P. aeruginosa is an opportunistic bacterium known to be responsible for numerous healthcare-associated infections, particularly in intensive care units (ICU). The frequency of these infections seems to have increased during the first waves of the COVID-19 pandemic. Identifying cases of co-infection and secondary infections with P. aeruginosa in patients with COVID-19 would provide a better understanding of the epidemiological evolution and characteristics of infected patients. Treatment of P. aeruginosa infections requires the use of antibiotics. Antibiotic resistance is a growing problem, with an increase in resistance among P. aeruginosa strains. The misuse of antibiotics to treat patients can accentuate the phenomenon of antibiotic resistance, and failure to take account of resistance revealed by antibiograms can compromise patient recovery. Analysis of bacteriological results and patient medical records would enable a posteriori evaluation of the proper use of antibiotics (choice and adaptation of molecules, doses and duration of prescriptions), and identify any areas for improvement. The main objective is to describe the evolution of P. aeruginosa infections in ICU patients with COVID-19 during the first 3 waves of COVID-19 (01/03/2020 to 31/05/2021). Secondary objectives are to describe the typology of P. aeruginosa strains identified among included patients (sampling sites and resistance profiles), to assess antibiotic prescriptions for these patients and to describe the relapse rate of included patients with a first P. aeruginosa infection.
