Filter by:The investigators performed in April 2020, a screening campaign of asymptomatic staff working in elderly nursing homes in Paris France (EHPAD), where the virus had been circulating actively in March and April 2020. Among 241 employees tested in four nursing homes, 32 (13.2%) were asymptomatic carriers of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-Cov-2). Few data are available concerning the humoral immune response of asymptomatic carriers, the elicitation and duration of neutralizing antibodies and the duration of protection. The purpose of the study is to determine whether these asymptomatic persons develop a humoral immune response, whether this immune response is durable and whether it is protective against the risk of reinfection
Popular topic：Clinical study on the immune program of recombinant Novel Coronavirus (COVID-19) vaccine (CHO cell). Research purpose:Main purpose: To evaluate the immunogenicity of recombinant novel coronavirus vaccine (CHO cells) inoculated at 0,1,6 months or 0,1,4 months in persons aged 18 years and over. Secondary purpose: To evaluate the safety of the investigational vaccine in people aged 18 and above. Overall design: In this study, recombinant novel coronavirus vaccine (CHO cells) is inoculated at 0,1,6 months or 0,1,4 months in persons aged 18 years and older to evaluate the immunogenicity and safety. Study population:The study involved people 18 years of age and older. Test groups：A total of 300 subjects were enrolled, including 221 in the 18-59 age group and 79 in the ≥60 age group. Three doses of experimental vaccine were administered according to the 0,1,6 month immunization schedule (Study No. 001-150) or 0,1,4 months immunization schedule (Study No. 151-300).
The Coronavirus Pediatric Serological Study's aim is to provide a better insight of children's immune response after SARS-CoV-2 infection. Serological tests were conducted on blood samples taken 3 to 5 months after the children's viral infection. The study was performed in collaboration with the Institute of Medical Immunology, were antibody levels were measured and immunoglobulin subclasses profiles were studied.
With lockdown, Emergency Departments (ED) visits decrease, principally for visits unrelated with Covid-19. In this study, the investigators aimed to find a correlation between ED visits and incidence rate of Covid-19 in a French metropolis.
The purpose of this study is to investigate the efficacy of proxalutamide or hospitalized moderate-to-severe COVID-19 patients.
Background and objective Vitamin D is important as the interaction between vitamin D and its receptors at the immune cells stimulates innate and adaptive immunity. Deficiency in vitamin D is associated with increased susceptibility to infection and it is commonly found in Indonesia. Several studies indicate the potential of vitamin D supplementation against Coronavirus Disease 2019 (COVID-19), particularly in combating the proinflammatory situation as well as coagulopathy. This study aims to evaluate the supplementation of vitamin D in COVID 19 patients, particularly the changes in hematology parameters and other clinical parameters. Method A double-blind randomized clinical trial is conducted among moderate COVID 19 patients. High-dose of vitamin D is given orally in the intervention group, compared with a low dose of vitamin D. Hematology parameters, D Dimer, conversion time on Polymerase Chain Reaction (PCR) test, and clinical symptoms are assessed Hypothesis High Dose vitamin D shows a better hematology parameter, short PCR conversion time, and faster clinical recovery
The study aims to characterize the distributive pattern of viruses in upper airway and its relationship with influenza seasons, symptomatology and exposure setting. A total of 500 adults residing in Hong Kong would be recruited, who would complete a questionnaire and return self-collected nasal and throat swabs for metagenomic analyses.
This study will evaluate the efficacy, safety, antiviral activity, and pharmacokinetics of study drug RO7496998 (AT-527) compared to placebo in non-hospitalized adult and adolescent participants with mild to moderate coronavirus disease 2019 (COVID-19) in the outpatient setting.
This study will enroll up to 80 subjects with Chronic Post COVID-19 Syndrome. Subjects will receive four intravenous injections of either allogeneic HB-adMSC's or a placebo over 10 weeks with two follow-up visits and an end of study visit at week 26.
To fast respond the coronavirus disease of 2019 (COVID-19) pandemic, the Indonesian government has launched "Vaksinasi Gotong Royong" (a mutual cooperation vaccination program) in which any company/legal entity/business entity may purchase vaccines to be given free of charge to their employees and families of employees (The Indonesian Ministry of Health, 2021). Vaccines provided for this program include the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inactivated vaccines produced by Sinopharm. The Indonesian National Agency of Drug and Food Control (NADFC) has issued an Emergency Use Authorization (EUA) for several COVID-19 vaccines, including the SARS-CoV-2 vaccine (Vero cell) inactivated produced by Sinopharm (NADFC, 2021). Following EUA, Kimia Farma Indonesia as the holder of EUA has the obligation to monitor the safety and effectiveness in Indonesian population.
