Filter by:The purpose of this study is to evaluate the efficacy, safety, and tolerability of VIR-2482 compared to placebo in preventing influenza A illness in healthy adults 18 to <65 years of age without pre-existing risk factors for serious complications from influenza infection.
The purpose of this study is to demonstrate the non-inferior HAI immune response of quadrivalent recombinant influenza vaccine (RIV4) vs licensed Egg-Based Quadrivalent Influenza Vaccine (IIV4) for the 4 strains based on the egg-derived antigen in all participants aged 3 to 8 years and to describe the immunogenicity and safety profile of RIV4 compared to IIV4 in participants aged 3 to 8 years.
Molecular techniques for respiratory virus detection have already shown benefits in terms of sensitivity gained in comparison to conventional techniques. Recent progress has made it possible to shorten turnaround time (TAT) and to allow delivery of results in a timely manner, especially in comparison to cell culture and direct fluorescence assays (DFA). However, the cost of these molecular assays is usually not taken in charge by public health insurance system. This could be partly explained by the fact that molecular techniques have not clearly shown cost-effectiveness. Results of molecular tests for influenza viruses and RSV, if delivered rapidly, in the emergency room (ER), would most likely help avoid antibiotic use and ancillary test prescription, improve antiviral prescription and shorten length of stay in the ward by facilitating discharge or cohorting of hospitalized patients. The goal of this study is to assess the performances of Roche Cobas® Liat Influenza A/B & RSV assay, to appraise its clinical impact and to evaluate its cost effectiveness.
Scarce information exists in relation to the effect of supplementation of Vitamin D3 in SARS-COV-2 infection, H1N1, and A, B Influenza when 25-hydroxyvitamin levels are between 20-100ng/ml. This study will evaluate the effect of supplementation of vitamin D3 vs. dietary-hygiene measures in SARS-COV-2 , H1N1, A, B Influenza infection rate in patients with serum 25-hydroxyvitamin D3 levels >20ng/ml. A comparative randomized study that will evaluate the effect of a monthly supplementation with 52000 units of Vitamine D3 during three months vs hygienic-dietary measures in the development of respiratory infections such as COVID-19, H1N1, A, B Influenza during 6 months of follow-up in health workers from a hospital in Northern Mexico with serum vitamin D values +/- 20ng/ml. Also, patients that during screening have 25-hydroxyvitamin D3 levels <20 ng/ml will receive vitamin D supplementation according to primary care discretion for three months and will be followed for 6 months and infection rate will be analyzed and compared.
This study is a stepped-wedge cluster-randomized trial of on-site rapid testing and treatment for influenza in homeless shelters within the Seattle area to determine whether this strategy reduced the incidence of influenza in the shelter environment.
Primary Objective: To demonstrate the superior relative effectiveness of QIV-HD as compared to QIV-SD among persons 65 years of age and older for the prevention of cardiovascular and/or respiratory hospitalizations. Secondary Objective: - To assess the clinical relative effectiveness of QIV-HD as compared to QIV-SD in prevention of: - inpatient hospitalization for selected circulatory and respiratory causes - death, either all-cause or cardiovascular or respiratory causes - inpatient hospitalization (using primary and secondary discharge diagnoses) - inpatient hospitalization (using admission diagnoses) - hospital emergency room visits - primary care visits to physician or - major acute cardiovascular events (MACE) - To assess the characteristics of inpatient hospitalization or hospital emergency room visits or primary care visits to physician by QIV-HD and QIV-SD groups. - To describe the clinical relative effectiveness of QIV-HD as compared to QIV-SD: - by age group and by group with specific comorbidities - for different periods of observation - To describe all serious adverse events (SAEs) (including adverse event of special interest [AESIs]) for all subjects in both QIV-HD and QIV-SD groups.
A Phase 2b Study to Determine the Efficacy of Candidate Influenza Vaccine MVA-NP+M1 in Adults aged 18 years and over. To assess the effect of MVA-NP+M1 on the reduction of laboratory confirmed influenza when given as an adjunct to licensed quadrivalent influenza vaccine (QIV) in adults
The goal of this study is to understand the impact on the human immune system's response to the four strain flu vaccine in individuals who have "imprinted" on specific influenza strains. It will also consider the effects of repeated prior annual influenza vaccination on the immune system.
A Phase 2 trial to confirm the dose and formulation, demonstrate adjuvant effect, and evaluate the safety and tolerability of a single intramuscular injection of Quad-NIV with or without Matrix-M1 adjuvant in healthy adults ≥ 65 years of age. A total of approximately 1375 subjects were to be randomized to seven treatment groups to receive Quad-NIV or an active comparator.
This study is a Phase IIb, Randomized, Double-blind, Multicenter, Placebo-controlled study evaluating the efficacy and safety of CT-P27 in subjects with acute uncomplicated influenza A infection.
