Filter by:The aim of the study is to demonstrate safety and immunogenicity of the quadrivalent influenza intradermal (QIV-ID) vaccine compared to the trivalent influenza vaccine (TIV) containing the B strain from the primary (Yamagata) lineage (TIV-ID1) and the trivalent influenza vaccine containing B strain from the alternate (Victoria) lineage (TIV-ID2) vaccines in producing protection against four strains of influenza virus. Primary Objective: - To demonstrate that QIV-ID induces an immune response (as assessed by hemagglutination inhibition (HAI) geometric mean titers (GMTs) and seroconversion rates) that is non-inferior to responses induced by TIV-ID1 and TIV-ID2 for the 4 virus strains at 28 days post-vaccination. Secondary Objectives: - To demonstrate that each B strain in QIV-ID induces an immune response (as assessed by HAI GMTs and seroconversion rates) that is superior to the response induced by the TIV-ID that does not contain the corresponding B strain. - To describe the rate of post-vaccination seroprotection induced by QIV-ID and TIV-ID. - To describe post-vaccination immunogenicity stratified by age (18-49 years and 50-64 years), race, ethnicity, gender, previous vaccination status, and baseline seropositivity status. - To describe the safety profile for subjects who receive QIV-ID and TIV-ID. Observational Objectives: - To demonstrate non-inferiority of QIV-ID compared to TIV-ID in terms of all Grade 2 or Grade 3 solicited systemic reactions combined - To demonstrate non-inferiority of QIV-ID compared to TIV-ID in terms of all Grade 3 solicited injection site reactions combined.
The purpose of this study is to investigate the immunogenicity, reactogenicity and safety of the new influenza vaccine GSK2282512A (FLU-Q-QIV) and compare its activity to the marketed vaccine Fluarix® (TIV) in young children 6 to 35 months of age.
The project aims to evaluate the impact of skin routes of immunization (transcutaneous and intradermal vs intramuscular) on cellular and humoral responses to seasonal influenza vaccination in adults (18-45 years old).
The purpose of this study is to assess the safety and immunogenicity of GSK Biologicals' investigational vaccine GSK2321138A in children who previously participated in study 115345 (FLU D-QIV-004 PRI) (NCT01439360).
Seasonal influenza (flu) is a significant and sometimes serious health issue in the U.S. The Centers for Disease Control (CDC) estimates that over 200,000 people are hospitalized in the U.S each year related to the flu. Public health campaigns advocate widespread vaccination for the flu, and especially for high risk people. People with cancer are high risk, with an increased risk of developing complications from the flu, such as pneumonia, bronchitis, or worsening of other medical conditions. As part of their vaccination campaign, the CDC strongly encourages inpatients to be vaccinated prior to hospital discharge. Accordingly, Stony Brook Hospital has enacted a policy that mandates screening all hospital inpatients for vaccination prior to discharge. While physicians or patients can opt not to vaccinate, the default is to proceed. Surgical oncologists have several concerns about vaccinating their patients after major surgical procedures. Patients with cancer have impaired immunity, and the ability of our patients to mount an effective immune response to the vaccine is unclear. Conversely, due to their immunocompromised state, our patients may be more susceptible to complications from the vaccine, such as influenza-like-illness (ILI), or have higher rates of postoperative complications due to the additional immune challenge of the vaccine. Previous studies have evaluated the flu vaccine in patients receiving chemotherapy, or after organ transplantation, but the combination of cancer and major surgery remains unstudied. This is a collaborative study with Infectious Diseases and Microbiology to evaluate the response to the flu vaccine in patients with pancreatic or gastric cancer, soft tissue sarcoma or peritoneal surface disease (i.e. carcinomatosis from appendiceal or colon cancers). Patients will be randomly selected to receive the vaccine either 2 weeks preoperatively or postoperatively at the time of discharge. Serum antibody response, rates of ILI and post-op complications will be analyzed. The long term goal of this study is two-fold: to determine the optimal time to vaccinate this group of patients in relation to their surgery, and to improve compliance with vaccination.
Vaccinating schoolchildren against influenza would prevent the disease among non-vaccinated household members.
The aim of this study is to evaluate the safety and immunogenicity of Fluzone vaccine (18 years to <65 years of age and ≥ 65 years of age), Fluzone Intradermal vaccine (18 years to <65 years of age), and Fluzone High-Dose vaccine (≥ 65 years of age). Primary Objective: - To describe the safety of the 2012 - 2013 formulation of Fluzone and Fluzone Intradermal vaccines in adults 18 to < 65 years of age and the safety of the 2012 - 2013 formulation of Fluzone and Fluzone High-Dose vaccines in adults ≥ 65 years of age. Observational Objectives: - To describe the immunogenicity of the 2012 - 2013 formulation of Fluzone and Fluzone Intradermal vaccines in adults 18 to < 65 years of age and the immunogenicity of the 2012 - 2013 formulation of Fluzone and Fluzone High-Dose vaccines in adults ≥ 65 years of age. - To evaluate the compliance, in terms of immunogenicity, of each study vaccine (Fluzone, Fluzone Intradermal, and Fluzone High-Dose) in the applicable age group with the requirements of the Committee for Human Medicinal Products (CHMP) Note for Guidance (NfG) CPMP/BWP/214/96. - To submit remaining available sera from subjects given Fluzone vaccine to the Center for Biologics Evaluation and Research (CBER) for further analysis by the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA) to support selection and recommendation of strains for subsequent years' influenza vaccines.
The aim of this clinical study is to demonstrate safety and immunogenicity of Fluzone vaccine. Objective: - To describe the safety of the 2012-2013 formulation of Fluzone vaccine, administered in a 1- or 2-dose schedule, in accordance with Advisory Committee on Immunization Practices (ACIP) recommendations, in children 6 months to < 9 years of age. Observational Objectives: - To describe the immunogenicity of the 2012-2013 formulation of Fluzone vaccine, administered in a 1- or 2-dose schedule in accordance with ACIP recommendations, in children 6 months to < 9 years of age. - To submit remaining available sera from subjects to the Center for Biologics Evaluation and Research (CBER) for further analysis by the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA) to support selection and recommendation of strains for subsequent years' influenza vaccines.
This is a prospective, randomized, double-blind, placebo-controlled trial that will be conducted in tertiary care pediatric hospitals in El Salvador and Panama. The primary purpose of this study is to determine whether empiric oseltamivir phosphate treatment given at the time of hospital admission to children less than 10 years of age hospitalized with influenza can effectively reduce their illness severity. Additional objectives are to: 1) evaluate the tolerability of oseltamivir phosphate treatment, 2) evaluate the effect of oseltamivir treatment on viral clearance and development of oseltamivir-resistant influenza virus during and after treatment in children hospitalized with influenza, 3) estimate the direct and indirect costs of all-cause respiratory illness and influenza-associated respiratory illness requiring hospitalization, and 4) evaluate the effect of empiric oseltamivir treatment during the influenza season on these costs. The primary study hypothesis is that children with laboratory-confirmed influenza receiving empiric oseltamivir phosphate treatment initiated at the time of hospital admission will have a shorter duration of hospitalization and a shorter time to resolution of signs of severe respiratory illness compared to children receiving placebo. The secondary study hypotheses are that children with laboratory-confirmed influenza receiving oseltamivir phosphate treatment will have a reduction in the time to non-detectable influenza virus and influenza viral RNA and children with all-cause respiratory illness receiving oseltamivir phosphate will not be more likely to experience severe adverse events than children receiving placebo.
The purpose of this study was to demonstrate the safety and immunogenicity of an oral vaccine tablet to prevent seasonal influenza. The study was a placebo controlled, double blinded trial at a single site. The study was conducted under two separate protocols. Initially single administrations at two dose levels (low dose and mid dose) of the oral vaccine was tested in a placebo controlled study (37 subjects). And subsequently a single high dose of the oral vaccine was tested in a separate placebo-controlled study (24 subjects).
