Filter by:The purpose of this study is to test whether messages that make it easy to schedule a flu shot appointment will increase flu shot rates in patients without an upcoming appointment. The study will also test which message versions and message timing are most effective for increasing flu vaccination.
The purpose of this study is to assess, prospectively, the effect on flu vaccination rates of salient alerts in the electronic health record that indicate a patient's high risk for flu and its complications. The investigators hypothesize that the salient alerts will lead to increased flu vaccination compared with a standard flu alert.
This study will evaluate the efficacy, safety, and population pharmacokinetics of a single, oral dose of GP681 compared with placebo in patients aged 12 to 65 years with acute uncomplicated influenza virus infection
The primary aim is to define the immune responses to the infant's initial influenza exposure (vaccine or infection) and how that affects the immune response to subsequent influenza exposures
The objective is to describe the safety profile after 1 dose of VaxigripTetra inj. administered in subjects aged 3 years old and above under routine clinical practice. The planned duration of each subject's participation in the study will be 21 to 28 days.
To explore the immunogenicity and safety of quadrivalent split influenza virus vaccine in children aged 3-8 years with two doses and one dose. This clinical trial was designed as a self-controlled trial to observe the immunogenicity and safety. This study was an exploratory study. Sample size and test grouping: In this study, a total of 360 subjects were enrolled in a self-controlled trial design. In this study, 360 subjects aged 3 to 8 years old were enrolled. According to their previous influenza vaccine vaccination status, they were assigned to experimental group 1 (no previous influenza vaccine), experimental group 2 (one dose of influenza vaccine previously) and experimental group 3 (two or more doses of influenza vaccine previously), with 120 cases in each experimental group. All subjects received one dose of tetravalent influenza virus lysis vaccine on day 0,28 for immunogenicity and safety observation.
The primary goal of this study is to evaluate the safety, reactogenicity, and immunogenicity of mRNA-1073 compared to co-administered mRNA-1010 and mRNA-1273 vaccines and to the individual vaccines alone in healthy participants.
A comparison of clinical characteristics and outcomes of patients on extracorporeal membrane oxygenation (ECMO) in COVID-19, influenza and ARDS of other ethiologies
This study examines how the immune system responds to the flu virus (H3N2) during and after infection and how the flu virus is transmitted in the environment. The study will used a flu virus called the H3N2 influenza challenge virus which was produced specifically for use in clinical research in controlled conditions. The study will also assess the safety of the H3N2 influenza challenge in healthy subjects. Mild to moderate symptoms are expected based on previous studies with this strain of influenza.
Comparative assessment of the tolerability, safety and immunogenicity of the Flu-M vaccine vs. the Ultrix® vaccine by single vaccination of children aged 6 to 17 years.
