This study may provide safety information on a flu vaccine given to children and may provide immunogenicity information to add to what was collected in a previous flu vaccine study. Participants will include 55 healthy children, ages 2-10, who participated in 04-077 and received a placebo injection instead of the flu vaccine or were incompletely immunized. The study has 2 purposes: to make sure there are no serious side effects in children and to see how the immune systems react to the vaccine. Study procedures include up to 4 study visits, up to 9 follow-up phone calls, 2 blood samples to be collected during visits 1 and 3, and up to 3 vaccine injections in the arm or thigh muscle. Parents will be given a memory aid card to record side effects, temperatures, and medications. Parents will have the option for the child to receive a 3rd dose of vaccine if offered, at month 6. This booster shot will require a 6-month visit and participation for an additional 6 months.
The purpose of this trial is to assess the knowledge and attitudes of post-partum women regarding influenza and the use of the influenza vaccine in pregnancy.
The present study is designed to evaluate the immunogenicity and safety of a single or double dose of the pandemic influenza candidate vaccine (GSK1562902A), administered following a two-administration schedule (21 days apart) in adults over 60 years of age. The persistence of influenza antibodies will also be evaluated 24 months after vaccination.
The purpose of this study were to obtain additional evidence in support of the safety and immunogenicity of a recombinant hemagglutinin (rHA) vaccine in an elderly population, and to establish non-inferiority of the immunogenicity of the rHA vaccine when compared with a licensed trivalent influenza vaccine (TIV). Another purpose was to provide a preliminary estimate of the relative efficacy of the two vaccines against culture-positive influenza-like illness during the subsequent epidemic.
The purpose of this study is to learn how to treat influenza in children less than 2 years of age. Tamiflu®, the drug being studied, is approved for treatment of children 1 year of age and older with influenza. Researchers want to learn more about the activity of Tamiflu® in the body to determine a dose of that is safe, well-tolerated, and effective in young children with influenza. Children less than 24 months of age with confirmed influenza will receive Tamiflu® 2 times a day for 5 days. Older participants will be enrolled first and younger children will be enrolled after the safety data is reviewed for older participants. Study procedures include blood samples, swabs from inside the nose, and body and nervous system evaluations. Participants may be involved in study related procedures for up to 37 days.
Primary Objective: To evaluate for each influenza strain the non-inferiority of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years. Secondary Objectives: - To describe the immunogenicity of of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years. - To describe the safety of of Investigational Fluzone vaccine to the standard Fluzone® vaccine in healthy subjects aged 6 to 35 months or 3 to 8 years.
Compared to young adults, the elderly mount a lower antibody response to vaccination. Thus, improvement of the immune response to influenza vaccination in this age group, which is at higher risk for influenza-related morbidity and mortality, represents an important unmet need. Primary Objectives: Immunogenicity: - To demonstrate lot consistency of the Fluzone High Dose (Fluzone HD) manufacturing process through evaluation of the immune responses elicited by three different lots. - To demonstrate the superiority of Fluzone HD vaccine compared to standard-dose Fluzone® vaccine. Secondary Objectives: Immunogenicity: - To describe the seroprotection of Fluzone HD compared to that of standard dose Fluzone® vaccine. Safety: - To describe the safety profile of Fluzone HD, in terms of solicited -, unsolicited adverse and serious adverse events post-vaccination. - To describe clinical information on some additional defined criteria during the six months following vaccination.
To compare the groups with respect to influenza immune responses following Dose 1 of Fluzone vaccine (2006-2007 formulation).
To provide Centers for Biologics Evaluation and Research (CBER) with sera collected from healthy children receiving the 2006-2007 formulation of the inactivated, split-virion influenza vaccine Fluzone® for further study by the Food and Drug Administration (FDA), Center for Disease Control and Prevention (CDC) and World Health Organization (WHO).
