Filter by:Primary Objective: To describe the immune response to a single administration of 2 formulations of the investigational cell-based influenza vaccines in healthy adult subjects. Secondary Objective: To describe the safety following a single administration of 2 formulations of the investigational cell-based influenza vaccines in healthy adult subjects.
Rates of confirmed influenza illness in vaccinated and non-vaccinated children will be compared between schools with and without vaccination programs. The investigators hypothesize that in addition to lowering rates of influenza in vaccinated children, raising vaccination rates by 30-40% through school-based vaccination programs will decrease incidence of influenza in non-vaccinated children attending those schools compared to non-vaccinated children in schools with low vaccination rates.
The present study, phase III, randomized, controlled, observer-blind, multicenter study, will evaluate safety, tolerability and immunogenicity of two doses of an adjuvanted monovalent influenza vaccine compared with an adjuvanted interpandemic trivalent influenza vaccine in a population of healthy adult and elderly subjects.
The present study will evaluate the immunogenicity, safety and tolerability of two doses of monovalent inactivated influenza vaccine that is adjuvanted with MF59C.1 (MF59) and uses a surface antigen from a potential pandemic virus strain candidate (H5N1) in Adult and Elderly Subjects.
To describe the safety findings from Days 0 to 44 following injection of the 2003-2004 pediatric formulation of the inactivated, split-virion influenza vaccine Fluzone®, given in the two-dose schedule in accordance with the Package Insert, in children aged ≥ 6 months to < 36 months. To describe the immunogenicity findings from Days 0 to 44 following injection of the 2003-2004 pediatric formulation of the inactivated, split-virion influenza vaccine Fluzone®, given in the two-dose schedule in accordance with the Package Insert, in children aged ≥ 6 months to < 36 months
To describe the safety during days 0 to 21 following injection of the 2003-2004 formulation of the inactivated, split-virion influenza vaccine Fluzone® in subjects aged 18-59 years and subjects aged ≥ 60 years. To describe the immune response at 21 days following injection of the 2003-2004 formulation of the inactivated, split-virion influenza vaccine Fluzone®, in subjects aged 18-59 years and subjects aged ≥ 60 years.
With this study the investigators will try to assess the tolerability and measurability of the efficacy of non pharmaceutical measures to prevent seasonal influenza in individual households. Households with an identified index case of influenza will be randomised into one of three intervention arms: 1. group, where the household will receive general information about transmission of influenza virus and means to prevent it (Controls); 2. group, which will receive surgical masks and be asked to wear them whenever they are in close contact with the index case or other persons of the household that became ill during the observation period; 3. group, which will be given and asked to wear surgical masks as well as to execute intensified hand hygiene. In addition to assessing the secondary attack rate as our primary outcome measure, the investigators will also try to evaluate compliance to those interventions by questionnaires.
To observe and to describe the safety during Days 0 to 21 following injection of the 2004-2005 formulation of the inactivated, split-virion influenza vaccine Fluzone® in subjects aged 18-59 years and subjects aged ≥ 60 years. To measure and to describe the immune response (antibodies to hemagglutinin) 21 days following injection of the 2004-2005 formulation of the inactivated, split-virion influenza vaccine Fluzone®, in subjects aged 18-59 years and subjects aged ≥ 60 years.
To describe the safety of the 2004-2005 pediatric formulation of the inactivated, split-virion influenza vaccine Fluzone®, given in the two-dose schedule in accordance with the Package Insert, in children aged ≥ 6 months to < 36 months. To describe the immunogenicity of the 2004-2005 inactivated, split-virion influenza vaccine Fluzone®, administered in a two-dose schedule in accordance with the Package Insert, in children aged ≥ 6 months to < 36 months
