Filter by:This is an observer-blinded, randomized, placebo-controlled, parallel group study to evaluate safety and immunogenicity of TAP-V001 quadrivalent influenza vaccine in healthy adult subjects.
This is a non-controlled, open-label, single-centre, dose-escalation study to determine the safety, infectivity and immunology of the potential novel influenza virus H3N2 challenge strain. The term 'challenge agent' used in this protocol refers to the Influenza virus H3N2 A/Belgium/4217/2015. The study utilises an adaptive study design and consists of 2 parts.
To evaluate the immunogenicity and safety of 2 doses of quadrivalent influenza virus split vaccine in healthy population aged 6-35 month., so as to provide a data support for phase III clinical trials.
Efficacy of clarithromycin-naproxen-oseltamivir combination therapy vs. oseltamivir alone for hospitalised paediatric influenza patients
Multicapillary Ion mobility spectrometry of nasal air aspirates shall be investigated as screening tool for the detection of Influenza and SARS-CoV-2- infection.
The main goal of this research study is to use data from activity trackers (such as Fitbits), lab tests, and surveys to see if activity, sleep, and heart rate data can tell the difference between when someone has a respiratory illness (e.g., flu) and when they are feeling healthy. The research will also study an investigational flu@home test and app. If successful, results from the study could be used in the future to better identify people with respiratory illness. In addition, this study will test the accuracy of an at-home flu test kit compared to laboratory test results.
Invasive pulmonary aspergillosis (IPA) has been reported in critically ill patients with influenza infection with a highly variable incidence between 1 to 21%. Studies investigating IPA in critically ill patients with influenza infection suffer limitations in their methods. It remains unknown whether patients with influenza are more at risk of IPA than other patients hospitalized in intensive care unit and whether patients with influenza who develop IPA have specific risk factors for this infection. Our study aims to determine the incidence of IPA in a large multicenter cohort and to identify risk factors for IPA in these patients.
Influenza vaccine uptake remains low worldwide, inflicting substantial costs to public health and health systems. Messages promoting social welfare have been shown to increase vaccination intentions, and it has been recommended that health professionals communicate the socially beneficial aspects of vaccination. This study aims to provide the first test whether this prosocial vaccination hypothesis applies to the actual vaccination behaviour of high-risk patients by comparing the effects of two motivational messages for promoting vaccination at a tertiary care public hospital in Istanbul, Turkey.
The primary objectives of the study were: - To demonstrate the non-inferiority of the immune response in terms of geometric mean titers (GMTs) and seroconversion rates of the SP Shz QIV compared with the SP Shz TIV containing the Victoria lineage strain (TIV1) and the SP Shz TIV containing the Yamagata lineage strain (TIV2) for each strain - To describe the safety profile of each dosage of SP Shz QIV, TIV1 or TIV2 The secondary objectives of the study were: - Group 1 (subjects 6-35 months): To demonstrate the superiority of the immune response of SP Shz QIV compared to TIV2 or TIV1 group after the last dose; demonstrate the superiority of the immune response of the 0.5 mL dose of SP Shz QIV compared to 0.25 mL dose of SP Shz QIV group after the last dose; describe the immune response after administration of the last dose of either SP Shz QIV or SP Shz TIV1 or SP Shz TIV2. - Groups 2 through 5 (subjects ≥ 3 years): To demonstrate the superiority of the immune response of SP Shz QIV compared to TIV2 or TIV1 group after a single dose; describe the immune response after each and every dose for all subjects ≥ 3 years of either SP Shz QIV or SP Shz TIV1 or SP Shz TIV2 - Group 2 (subjects 3 to 8 years), previously unvaccinated ,receiving SP Shz QIV: To describe the immune response after administration of each dose of SP Shz QIV, first dose and second dose of SP Shz QIV respectively - Group 5 (subjects ≥ 65 years only): To assess the compliance, in terms of immunogenicity, of SP Shz QIV with the requirements of the CHMP NfG CPMP/BWP/214/96 in subjects aged 65 years or older. - To describe the safety profile of SP Shz QIV 0.5 mL after each dose.
The aim of the study is to investigate disease in volunteers deliberately infected with influenza A(H3N2), including biological markers of inflammation and immune response, and changes in physiological parameters including heart rate, respiratory rate, physical activity, oxygen saturation and electrocardiographic data during the onset of influenza infection. Ultimately, this may lead to prediction of symptomatic disease at an earlier stage to allow more effective interventions. The experimental medicine study design will involve human influenza infection challenge, whereby volunteers will be inoculated with influenza virus and monitored in hospital for 10 days as they develop and get better from flu. Continuously-monitoring wearable physiological sensors will be given to the participants 7 days before this and worn continuously until the end of the flu infection.
