Filter by: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.
Elderly healthy subjects will be once administered GC3114A(High-dose Quadrivalent influenza vaccine) or GCFLU Quadrivalent Pre-filled syringe inj..
Seasonal influenza vaccination was used to assess whether induction of immunity as well as the rate of side effects is influenced by the timing of the last training session before vaccination. Healthy athletes were vaccinated with the tetravalent influenza vaccine and blood samples were collected before, 1, 2 and 26 weeks after vaccination. The athletes were randomly assigned to vaccination within 2 hours after the last training session ("2h") vs. vaccination after a resting period of at least 26 hours ("26h"). All participants documented side effects and training restrictions. Influenza-specific T-cells were quantified after stimulation with the vaccine based on intracellular cytokine staining. Antibodies were quantified by ELISA and neutralisation assay.
This study will evaluate the safety, pharmacokinetics and efficacy of baloxavir marboxil in healthy pediatric participants from birth to <1 year with influenza like symptoms
The present clinical phase I study designed to examine the safety, reactogenicity and immunogenicity of the medicinal product - Vaccine vector against influenza A - in healthy volunteers after a single dose in the three groups with dose escalation.
To reach seasonal vaccination against influenza targets, University Hospitals Birmingham (UHB) already invites staff to take up the vaccination, and every November reminds staff that have not yet vaccinated to do so. The current protocol describes a randomized controlled trial (RCT) in which staff will be sent different reminders, and the investigators will compare the proportion of staff that go on to vaccinate after receiving each reminder.
This study will evaluate the safety, pharmacokinetics, and efficacy of baloxavir marboxil compared with oseltamivir in a single influenza episode in otherwise healthy pediatric participants (i.e., 1 to <12 years of age) with influenza-like symptoms.
The primary objectives of this study were: - To describe the immunogenicity of the 2018-2019 formulation of Fluzone® Quadrivalent vaccine in children 6 to less than (<) 36 months of age and 3 to <9 years of age, and in adults 18 to <65 years of age; the immunogenicity of the 2018-2019 formulation of Flublok® Quadrivalent vaccine in adults 18 to <65 years of age; and the immunogenicity of the 2018-2019 formulation of Fluzone High-Dose vaccine in adults greater than or equal to (>=) 65 years of age. - To describe the safety of the 2018-2019 formulation of Fluzone Quadrivalent vaccine in children 6 to <36 months of age and 3 to <9 years of age, and in adults 18 to <65 years of age; the safety of the 2018-2019 formulation of Flublok Quadrivalent vaccine in adults 18 to <65 years of age; and the safety of the 2018-2019 formulation of Fluzone High-Dose vaccine in adults >=65 years of age.
The purpose of this study is to evaluate immunologic response to different types of influenza vaccine among children/adolescents/young adults 4-20 years of age. This is a randomized controlled trial (RCT), that will assess immune response in 120 participants (60 per vaccine arm) pre- and post-vaccination to Flucelvax (egg-free inactivated flu shot) and Fluzone (egg-based inactivated flu shot).
The purpose of this research study is to better understand the immune response to the Adjuvanted Subunit flu vaccine (MF59) and the High Dose flu vaccine (HDFlu) in people 65 years of age and older. The research team will be studying why immune response diminishes as people get older in both men and women. The ultimate goal is to understand how flu immunity develops after vaccination. This information may lead to the development of more effective flu vaccines in the future.
