Active clinical trials for "Influenza, Human"

Vaccinating schoolchildren against influenza would prevent the disease among non-vaccinated household members.

Evaluate the safety and immunogenicity of three dosage levels of swine influenza vaccine in children ages 3 to <9 years, adolescents 9 to <18 years, adults 18 to <65 years and elderly 65 years and older.

The purpose of this study is to evaluate the safety and immunogenicity of different formulations of GSK Biologicals H7N1 influenza vaccine in subjects 21 to 64 years of age. The study will evaluate safety related events and antibody immune responses to different formulations of study vaccine and placebo.

Evaluate the safety and immunogenicity of four different doses of H7N9 vaccination in adults between the ages of 18 years and 65 years.

Since October 2009, H1N1 influenza vaccine has developed and approved of immunization in population in China. However, there was little epidemiological evidence of safety when vaccinated in healthy pregnant women. The main objective of this study is to assess the safety of split-virion inactivated H1N1 vaccine without adjuvant when administered in healthy pregnant women. It is a stratified and controlled clinical trial in healthy pregnant women. And participants were included up to 226 healthy pregnant women aged 18 -35 years old who have no history of novel influenza H1N1 infection or novel influenza H1N1 vaccination. The pregnancy week ranged from 5 weeks to 32 weeks. Subjects were divided into 2 groups: vaccinated group（122） and unvaccinated group（104）. Subjects in the vaccinated group were administered one dose of 15μg H1N1 vaccine. Subjects in the unvaccinated group received no vaccine as controls. Safety will be measured by assessment of pregnancy outcomes. And observation time for pregnancy outcomes was lasting for 28 days postpartum since vaccinated; and protective effect was observed for six months.

The hypothesis for this trial is that the incidence of a pre-defined composite of common systemic hypersensitivity adverse events for Flublok recipients is non-inferior to that reported for licensed IIV recipients. Another hypothesis is that the safety and reactogenicity of Flublok is clinically acceptable, i.e. consistent with the overall safety profiles previously observed with Flublok and with the licensed comparator.

The main purpose of this study is to assess the safety and ability of a Panblok H7 influenza vaccine adjuvanted with AS03 or MF59 to generate an immune response after 2 doses separated by 28 days. Three different antigen dose levels of Panblok H7 will be tested.

This Phase 3 study evaluates the safety, immunogenicity and lot-to lot consistency of 3 lots of aH5N1c vaccine for pandemic avian influenza, in approximately 2394 healthy adults ≥18 years of age receiving the vaccine and 797 healthy adults receiving placebo. Subjects were randomized in a 3:1 ratio to receive either aH5N1c vaccine or saline placebo. Enrollment was stratified by age: 18 to <65 years of age and ≥65 years of age, to allow adequate safety assessment of the entire age spectrum.

The administration of adjuvanted Trivalent Influenza Vaccine (aTIV) has come to result in a more immunogenic and effective response compared with conventional influenza vaccines in elderly and adults. The aim of this study is to evaluate safety and immunogenicity of Novartis aTIV in children 6 to <72 months of age, Mexican population, in comparison to Fluzone, a non-adjuvanted trivalent influenza vaccine (TIV).

A phase I prospective, randomized study in healthy adult subjects at a single center. Adult subjects age 18 to 47 years and meeting all enrollment criteria will choose to participate as subjects who receive inactivated vaccine followed by a live vaccine boost at 4 weeks (Group 1), 12 weeks (Group 2), or 24 weeks (Group 3), or to be in an observational group (Group 4) which will not be scheduled for a booster dose but may serve as a roll-over group for subjects who withdraw prior to the second vaccination but agree to remain in follow-up. A fifth group will receive two intramuscular doses of adjuvanted H7N9 pIIV separated by four weeks. The primary objectives of this study are to (1) assess the safety of H7N9 pLAIV administered to individuals who have previously received MF59-adjuvanted or unadjuvanted H7N9 pIIV, (2) evaluate the ability of a single dose of unadjuvanted H7N9 pIIV to prime for enhanced immunogenicity (booster response) to subsequent administration of antigenically-matched H7N9 pLAIV vaccine, and to (3) evaluate the ability of a single dose of MF59-adjuvanted H7N9 pIIV to prime for enhanced immunogenicity (booster response) to subsequent administration of antigenically-matched H7N9 pLAIV vaccine.
