Active clinical trials for "Influenza, Human"

This Phase 2 Quadrivalent VLP Vaccine study is intended to replicate and extend the immunogenicity and safety results obtained in earlier Phase 1-2 and Phase 2 studies. The study is being conducted to demonstrate that the immunogenicity profile of the Quadrivalent VLP Vaccine meets the US Center for Biologics Evaluation and Research (CBER) licensure criteria. The study will also help to define the optimal dose, establish potential competitive advantages, and support the design of future studies.

This prospective annual release study is designed to evaluate the safety of 1 new influenza virus vaccine strain to be included in FluMist Quadrivalent for the 2017-2018 influenza season.

The purpose of this study is to determine if the administration of flu vaccine using Needle-Free is equivalent to Needle and Syringe administration as measured by laboratory tests of immune response.

The purpose of this study is to describe the immunogenicity and safety of the cell culture-derived influenza vaccine compared with the egg-derived influenza vaccine among subjects. To describe the immunogenicity, antibody levels are evaluated by hemagglutination inhibition(HI) assay from sera obtained pre-vaccination and 21 days post-vaccination. To describe the safety, the time of onset and duration of local and systemic solicited adverse events are assessed and reported. Unsolicited adverse events and serious adverse events are collected and categorized throughout the study period.

Immunogenicity and Tolerability Study of Fluval AB Novo Suspension for Injection (trivalent, seasonal influenza vaccine, active ingredient content: 6 μg HA/strain/0.5 ml) for Children and Adolescents.

Background:<TAB> - Flu virus that causes disease in birds can sometimes spread to people. It can cause severe illness, even death. Vaccines are used to try to create resistance to such infections. Researchers want to test a new vaccination strategy, combining two different vaccine types, the H7 DNA Vaccine (DNA vaccine) and H7N9 Monovalent Inactivated Vaccine (MIV), to see if one of two combinations offer better protection against a certain type of bird flu in humans when compared to vaccination using two doses of MIV alone. Objectives: To see if 2 vaccines for bird flu, are safe and tolerable for humans. To study immune responses to these vaccines. Eligibility: - Healthy adults 18 60 years old. Design: Participants will be screened through a separate protocol. Participants will be randomly assigned to 1 of 3 groups. Each group will get a different combination of vaccines. Participants will have about 8 clinic visits. Each visit takes 2 4 hours. Blood will be drawn at some visits. Urine samples may be collected. Participants will receive vaccinations at 2 of the visits, 16 weeks apart. The H7N9 MIV will be injected in the upper arm using a needle and syringe. The DNA vaccine will be injected in the upper arm using a device that delivers the vaccine through the skin by pressure instead of a needle. Participants will be observed for at least 30 minutes after each vaccination. Soon after each vaccination, participants will get 1 2 phone calls, come to clinic for evaluation, and complete a diary at home for 1 week. They will record their temperature and symptoms and look at the injection site daily. Participants will have follow-up blood tests.

This is a study to assess the immune (antibody) response and safety of a bioCSL split virion, inactivated quadrivalent influenza vaccine, in comparison with a US licensed 2014/2015 trivalent influenza vaccine (bioCSL TIV-1), and a trivalent influenza vaccine containing the alternate B strain (bioCSL TIV-2), in healthy adult volunteers aged 18 years and above.

Similar to children, adults frequently visit outpatient clinics to get two or more kinds of vaccines at the same time: pneumococcal vaccine, influenza vaccine, Td (diphtheria and tetanus) vaccine, HPV (human papilloma virus) vaccine, meningococcal vaccine, zoster vaccine, etc. This study is intended to evaluate the immunogenicity and safety of concomitant administration of 23-valent pneumococcal polysaccharide vaccine (PPV23, Prodiax) and MF59 adjuvanted trivalent influenza vaccine in the elderly subjects aged ≥65 years.

The purpose of this study is to assess the immunogenicity and safety of GSK Biologicals' quadrivalent influenza vaccine (GSK2282512A) compared to Sanofi Pasteur's Fluzone® Quadrivalent in children 6 to 35 months of age.

The aim of this trial is to evaluate the safety and immunogenicity of the 2014-2015 formulations of Fluzone® Quadrivalent and Fluzone® Intradermal vaccines in adults 18 to < 65 years or age, and of the 2014-2015 formulations of Fluzone® Quadrivalent and Fluzone® High-Dose vaccines in adults ≥ 65 years of age. Objectives: To describe the safety of the 2014-2015 formulations of Fluzone Quadrivalent and Fluzone Intradermal vaccines in adults 18 to < 65 years of age and the safety of the 2014-2015 formulations of Fluzone® Quadrivalent and Fluzone® High-Dose vaccines in adults ≥ 65 years of age. Observational objectives: To describe the immunogenicity of the 2014-2015 formulations of Fluzone® Quadrivalent and Fluzone® Intradermal vaccines in adults 18 to < 65 years of age and the immunogenicity of the 2014-2015 formulations of Fluzone® Quadrivalent and Fluzone ®High-Dose vaccines in adults ≥ 65 years of age. To evaluate the compliance, in terms of immunogenicity, of each study vaccine (Fluzone® Quadrivalent, Fluzone® Intradermal, and Fluzone® High-Dose) in the applicable age group with the historical requirements of the Committee for Human Medicinal Products (CHMP) Note for Guidance (NfG) CPMP/BWP/214/96.
