Active clinical trials for "Influenza, Human"

The present study will evaluate the concomitant administration of a Quadrivalent Inactivated Influenza Vaccine with the highest dose level of OVX836 (480µg) tested in the clinic to date, for which the likelihood for interference with Quadrivalent Inactivated Influenza Vaccine is considered the highest.

The primary objective of this study is to evaluate the safety, reactogenicity, and humoral immunogenicity of mRNA-1020, mRNA-1030, and mRNA-1010 vaccines against vaccine-matched influenza A and B strains.

The aim of the study was to assess the immunogenicity and safety of Fluzone Quadrivalent influenza vaccine Southern Hemisphere (SH) 2015 formulation in participants aged 18 to 60 years as well as in participants 61 years or older. The objectives were: To evaluate the compliance, in terms of immunogenicity, of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation with the requirements of the European Medicines Agency (EMA) Note for guidance (NfG) CPMP/BWP/214/96 To describe the immunogenicity of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation To describe the safety of the Fluzone Quadrivalent influenza vaccine SH 2015 formulation

The objective of the present study is to evaluate the capability of the probiotic strain Lactobacillus coryniformis K8 CECT5711 (Lc K8) to enhance the immune response to influenza vaccine in elderly and the effect on respiratory symptoms related to respiratory infections. A randomized, double-blind, placebo-controlled trial was conducted between November of 2015 and April of 2016. A total of 98 residents of nursing homes aged more than 65 years were randomly assigned to receive Lc K8 or placebo for two weeks previous to influenza vaccination. Primary outcome was the percentage of seroconversion. Secondary outcome were the incidence of influenza-like illness and respiratory symptoms associated to respiratory infections during the follow-up period of 5 months. Serum cytokines and immunoglobulins levels were also evaluated.

The purpose of this study is to evaluate the safety and immunogenicity of a sublingual administration of NSV0001 in healthy male volunteers.

FLU-v is a vaccine that aims to protect against a wide range of flu viruses. The purpose of this study is to measure the immune responses induced by FLU-v vaccine. This study will look at how safe FLU-v is when administered and how successful it is in preventing flu or reducing the severity of the flu symptoms. The study requires 222 healthy volunteers 18-60 years old. Participation in the study will take a maximum of 7 months and consists of 5 visits. During visit 1, subjects will be examined by a doctor to make sure they are eligible to enter the study. A 15ml blood sample (a tablespoon) will be taken to check general health followed by a general physical exam. Medical history and some personal information will be collected. Subjects that have received the traditional flu vaccine in the past 6 months, and those females who are pregnant or breastfeeding will not be allowed in the study. Subjects of childbearing age must agree to use effective contraceptive methods. At visit 2, subjects will be randomly allocated to one of the four treatment groups summarised below: Treatment 1: FLU-v (test vaccine) at the start of the study (Day 0) and then again 21 days later Treatment 2: FLU-v (test vaccine) with an additional substance added [known as Montanide ISA 51] which improves the effect of the test vaccine. Injection will be given on Day 0 and then Placebo (no test vaccine) alone 21 days later Treatment 3: Placebo (no test vaccine) injection on Day 0 and then 21 days later Treatment 4: Placebo (no test vaccine) with an additional substance added [known as Montanide ISA 51] on Day 0 and then Placebo (no test vaccine) alone 21 days later Treatment will be injected under the skin in the upper arm on day 0 (visit 2) and 21 days later (visit 3). Blood samples will be taken before treatment (day 0), and on days 42 (visit 4) and 180 (visit 5) to the immune responses induced by the vaccine. Subjects will be asked to complete a diary card to write down any side effects that they may experience after vaccination. Subjects will also be asked to complete another diary card to document any flu-like symptoms experienced between December 2016 and March 2017, this time is officially considered as the flu season. During this period, if the subject experiences flu-like symptoms, a collection of a nose and tonsil swab will be arranged by the study site to confirm whether they have the flu or not.

It is the aim of the present study to compare the immunogenicity induced by a laser-assisted epidermally administered seasonal influenza vaccine to an intradermally administered seasonal influenza vaccine.

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 evaluate that the immunogenicity profile of the Quadrivalent VLP Vaccine meets the US Center for Biologics Evaluation and Research (CBER) licensure criteria and to evaluate if the immunogenicity and the safety profile of the Quadrivalent VLP Vaccine is acceptable and comparable to that of the FluLaval® Tetra and Fluzone® High-Dose (HD). The study will also help to define the optimal dose in this population, establish potential competitive advantages, and support the design of future studies.

An open label, non-comparative bridging study to evaluate the safety of GCFLU® (seasonal influenza vaccine) administered intramuscularly in healthy Vietnamese volunteer aged from 3 years old

Influenza virus is an important cause of morbidity in the transplant population and can lead to viral and bacterial pneumonia. Although the annual influenza vaccine is recommended for transplant patients, studies have shown that nonadjuvanted vaccine has poor immunogenicity. There are no studies that define the effect of adjuvanted vaccine in this population. The purpose of this study is to determine if a vaccination with FLUAD® results in improved immunogenicity as compared to standard vaccine in allo-HSCT recipients. Immunogenicity will be assessed by standard quantitative antibody titer assessments and using cell-mediated immunity measurements.
