Active clinical trials for "Influenza, Human"

A Phase 3, double-blind, randomized, placebo-controlled trial of a seasonal, trivalent, split, inactivated influenza vaccine produced by InstituteTorlak.

The aim of the study was to describe the safety and immunogenicity of a 0.5-mL dose (15 μg hemagglutinin [HA] per strain) of Fluzone Quadrivalent vaccine in children 6 to <36 months of age. Primary objective: To compare the rate of any fever (temperature ≥100.4 degrees Fahrenheit [38.0 degrees Celsius) following a 0.5-mL dose of Fluzone Quadrivalent vaccine to that following a 0.25-mL dose of Fluzone Quadrivalent vaccine during the 7 days after either vaccination (Dose 1 and Dose 2 combined) in participants 6 to < 36 months of age. Secondary objective: To compare antibody responses induced by a 0.5-mL dose of Fluzone Quadrivalent vaccine to those induced by a 0.25-mL dose of Fluzone Quadrivalent vaccine as assessed by geometric mean titer (GMT) ratios and seroconversion rate differences after the final vaccination in participants 6 to < 36 months of age. Other objectives: To describe the safety of 2 different dose levels of the 2016-2017 formulation of Fluzone Quadrivalent vaccine in participants 6 to < 36 months of age. To describe the immunogenicity of 2 different dose levels of the 2016-2017 formulation of Fluzone Quadrivalent vaccine in participants 6 months to < 36 months of age. To submit available sera from approximately 30 participants to the Center for Biologics Evaluation and Research for further analysis by the World Health Organization, the Centers for Disease Control and Prevention, and the FDA to support formulation recommendations for subsequent influenza vaccines.

The study is aim to evaluate the safety and immunogenicity of one dose (15 μg HA per strain per dose) of the GPO seasonal trivalent inactivated split virion influenza vaccine (Tri Fluvac) in healthy adults aged 18 to 49 years over 90 days post-injection.

This study is a randomized, double-blind phase Ⅳ clinical trial of quadrivalent influenza vaccine (Split Virion), inactivated manufactured by Sinovac Biotech Co., Ltd.The purpose of this study is to evaluate the lot-to-lot consistency, immunogenicity and safety of quadrivalent influenza vaccine (Split Virion), inactivated in health subjects aged 9-59 years old.

This Phase 2, randomized, observer-blind, dose-confirmation Clinical study is evaluating different formulations of MF59-Adjuvanted Quadrivalent Subunit Inactivated Influenza Vaccine. Approximately 1000 subjects are to be randomized into 1 of 4 possible treatment groups with 250 participants per group. Every participant will receive an influenza vaccine injection on Day 1 and will be followed up for approximately 6 months following injection. The primary immunogenicity analysis is based on Day 29 serology data.

Comparative study of tolerability, reactogenicity, safety and immunogenicity Flu-M [Inactivated Split Influenza Vaccine] vs. the Ultrix® vaccine for the prevention of influenza in pregnant women in the 2nd-3rd trimesters of pregnancy

This study aims to evaluate the safety and reactogenicity profile of CVSQIV at different dose levels.

Popular topic：Clinical study of recombinant Novel Coronavirus vaccine (CHO cell) combined with influenza vaccine. Research purpose:Main purpose:To evaluate the immunogenicity of recombinant Novel Coronavirus vaccine (CHO cells) combined with influenza vaccine in people aged 18 years and over. Secondary purpose:To evaluate the safety of recombinant Novel Coronavirus vaccine (CHO cells) combined with influenza vaccine in people aged 18 years and over. Overall design:An open experimental design was adopted in this study, and 300 subjects were planned to be enrolled. To evaluate the immunogenicity and safety of recombinant Novel Coronavirus vaccine (CHO cells) in combination with influenza vaccine. Study population:The study involved people 18 years of age and older. Test groups:A total of 300 cases were enrolled. 240 patients in 18-59 years old group, 60 patients in ≥60 years old group. There were 150 cases in group A, 120 cases in 18-59 years old group, and 30 cases in ≥60 years old group. There were 150 cases in group B, 120 cases in 18-59 years old group and 30 cases in ≥60 years old group.

A study to compare multiple dosage regimes of a protesomal intranasal vaccine.

This is a phase I, double-blind, randomized, placebo-controlled trial with two groups of participants to receive seasonal trivalent split, inactivated influenza vaccine (A/H1N1; A/H3N2 and B) or placebo (phosphate buffered saline). A total of 60 healthy male and female adults 18 through 45 years of age will be randomized to receive vaccine (30) or placebo (30).
