Filter by:The objective of this study is to evaluate the safety of the vaccine and the immune response to the vaccine in healthy adult volunteers 65 years of age or older. Volunteers will be assigned by randomization to receive either the vaccine or an inactive substance (placebo) by injections in the arm on two occasions over one month. The study will last approximately 10 months and will have a total of 7 visits.
This study is designed to test the immunogenicity and reactogenicity of the Fluarix™/Influsplit SSW® influenza vaccine containing the influenza strains recommended for the 2008-2009 season.
This is a follow-up of a previous dose-ranging study aimed at investigating 2 doses of the trivalent inactivated split virion influenza vaccine when administered by intradermal route with that of the current pharmaceutical presentation administered by intramuscular route. Primary Objective: To assess the immunogenicity of two pharmaceutical presentations of the trivalent inactivated split virion influenza vaccine 21 days after a single injection in subjects aged 18 to 57 years. Secondary Objective: To evaluate the safety profile during the 21-day period following each vaccination in each study group
Severe disease in humans due to bird influenza viruses (H5N1) has led to concern that this virus may result in a widespread outbreak of bird flu. The purpose of this study is to evaluate the dose and dosing schedule for 2 different types of H5N1 vaccine. Participants will be randomly assigned to 1 of 9 possible vaccine groups. All participants will receive 2 doses of Clade 1, Clade 2, or combination Clade 1 and 2 on Day 0. All participants will receive a second dose of the same vaccine or a different vaccine type on study day 7, 14, 28 or 180. Study participants will include about 500 healthy adult subjects, ages 18-49 years old, who have no history of prior H5 flu exposure or vaccination. Study procedures may include medical history, physical exam, and blood sampling. Subject participation may last up to 372 days. Several DMID studies have recently evaluated H5N1 vaccines in healthy adults, 04-063, 05-0090, 05-0015, and 05-0043.
The purpose of this study is to determine the Safety, Tolerability & Immunogenicity of CSL Limited's Influenza Virus Vaccine in a two dose primary vaccination series, with a 12-month booster vaccination, in a paediatric population equal to or greater than 6 months to less than 9 years old.
The purpose of the study is to characterize the immunogenicity & safety of 2 doses of GSK's avian flu vaccine GSK 1557484A given according to different regimens to adults aged 18 to 64 years
The trial will enroll up to 47 subjects. Qualified normal healthy volunteers will be enrolled in the study to receive the vaccine or placebo vaccine. Subjects will receive 2 vaccinations with the Biojector® 2000, and will be followed for 6 months to evaluate the safety of and the immune system's response to the vaccine. The safety and immune system's response will be studied throughout the trial.
The purpose of the study is to compare the safety of & immune response to a single dose of GSK Biologicals' cell-culture based influenza vaccine 138842A with that of a US licensed, egg-based trivalent influenza vaccine [Fluarix] in healthy adults.
The purpose of this research study is to study the safety and effectiveness of vaccinating individuals who have previously received an avian influenza vaccine derived from one type of H5N1 virus with a vaccine derived from a different type of avian influenza virus. A second reason for this study is to compare responses in people who have received two different but similar types of H5N1 vaccine to the responses in subjects who receive 2 doses of only the H5N1 vaccine used in this study. The information obtained may provide important information into the usefulness of a pre-pandemic vaccination. Participants will include 600 healthy adult volunteers, ages 19 and older, in the United States. Study procedures include: physical exams, vaccination with either a low dose (15 micrograms) or high dose (90 micrograms) of vaccine, blood samples, and maintaining a memory aid to record oral temperatures and side effects. Study participation will be approximately 7 months.
This prospective annual release study was designed to assess the safety of a trivalent influenza virus vaccine using a new strain recommended for the 2008-2009 influenza season not previously contained in the trivalent intranasal FluMist vaccine. Three hundred healthy adults received a single dose of vaccine or placebo and were followed for 180 days.
