Filter by:To estimate the incidence of H1N1v influenza-like illness and to study the risk factors for serious influenza forms during pandemic period in French HIV infected patients. - Definitions: - Influenza like illness is defined as fever> 37°8C and cough or pharyngalgia. (Centers for Disease Control definition). - Serious forms of influenza-like illness is defined by hospitalization within 14 days onset of symptoms or death attributed to influenza like illness. - Design: - Survey sampling for estimating H1N1v influenza-like illness incidence. - Out of approximately 50 000 patients under follow-up in one of the 40 ANRS centres, a sub-group will be selected by random sampling. Sampling will be stratified by centre and sampling fraction per site will vary in order to select 60 to 80 patients for this study per site. A total of 2500 to 3000 patients will be selected to allow for estimating the incidence of H1N1v influenza-like illness with an adequate precision. Selected patients will be asked to contact the clinical staff on site as soon as any influenza like symptoms appear. In the case of influenza like illness patients are requested to attend to the clinic within 24 hours for physical examination and naso-pharyngeal swab for diagnosis of A(H1N1)v infection. Nested case-control study for the determination of risk factors for serious forms: - Cases: Serious forms (see definition above) identified by any clinical site or hospitalisation unit. - Controls: Patients of the randomly selected sample (see survey sampling above), presenting with influenza-like illness without any criterion for severity. Exhaustivity check: The exhaustivity of symptomatic forms will be assessed a posteriori by merging information from all available data sources.
This is an observational study of safety and occurrence of influenza-like illness following administration of flu cell culture derived adjuvanted swine origin A (H1N1) pandemic subunit vaccine in subjects 6 months of age and older.
The primary objective of this observational, comparative safety study is to evaluate the safety of the Novartis Pandemic Influenza A (H1N1) vaccine in pregnant women and their off spring, followed for up to 3 months of age as compared to pregnant women who have not received the Novartis Pandemic Influenza A (H1N1) vaccine. This study will be conducted at investigative sites within the Netherlands, Italy, and Argentina.
The purpose of this study is to show that vaccination with a single dose of GSK Biologicals' pandemic H1N1 vaccine results in an immune response that meets or exceeds European Medicines Agency (EMEA) Committee for Medicinal Products for Human Use (CHMP) guidance criteria for a pandemic influenza vaccine.
This project is designed to assess the efficacy of immunizing women during pregnancy with influenza vaccine on the health of these women during their pregnancy and for 6 months post-partum as well as on the health of their newborn infants during the first 6 months of life. It will be conducted in Sarlahi District in southern Nepal, a rural area where a number of large scale randomized trials have been conducted over the past 20 years.
This open-label study will assess the pharmacokinetics/pharmacodynamics and safety of intravenous (iv) Tamiflu (oseltamivir) in 3 cohorts of children, aged 6-12, 3-5 and 1-2 years, with influenza infection. Patients will receive iv Tamiflu therapy for 5 days (10 doses). For patients whose conditions no longer merit continued iv dosing, therapy may be switched to oral Tamiflu to complete their prescribed course of treatment. If medically necessary, iv or oral therapy with Tamiflu may be continued for up to 5 additional days. Anticipated time on study treatment is 5 to 10 days.
This study is designed to assess the safety of the approved and licensed HUMENZA (adjuvanted A/H1N1 pandemic influenza vaccine) and PANENZA (non-adjuvanted A/H1N1 pandemic influenza vaccine) to meet regulatory requirements for post-marketing safety monitoring. Primary objective: To describe the incidence of serious adverse events and adverse events of special interest (AESIs) after HUMENZA or PANENZA administration throughout the study in different age groups. Secondary objective: To describe the incidence of non-serious cutaneous allergic reactions after HUMENZA or PANENZA administration in different age groups up to 21 days after the last vaccination.This study is designed to assess the safety of the approved and licensed HUMENZA (adjuvanted A/H1N1 pandemic influenza vaccine) and PANENZA (non-adjuvanted A/H1N1 pandemic influenza vaccine) to meet regulatory requirements for post-marketing safety monitoring.
This is a phase III, randomized, controlled, open label study with two vaccine regimens. The study will assess the relative safety and immunogenicity of vaccine regimens comparing adjuvanted versus non-adjuvanted formulations of A(H1N1) inactivated influenza virus vaccine in subjects with Human Immunodeficiency Virus Type 1 (HIV-1) Infection and to compare safety and immunogenicity data with a contemporaneously enrolled control group of age-comparable, healthy subjects. Because certain individuals may be hypo-responsive to influenza vaccination, additional studies with high-risk groups are warranted in order to determine the optimal vaccine formulation and dosing schedule for prevention of novel H1N1 virus infection.
This is a phase III, randomized, controlled, open label study with two vaccine regimens. The study will assess the relative safety and immunogenicity of vaccine regimens comparing adjuvanted versus non-adjuvanted formulations of A(H1N1) inactivated influenza virus vaccine in subjects with Chronic Pulmonary Disease, Chronic Heart Disease, or Diabetes Mellitus, and to compare safety and immunogenicity data with a contemporaneously enrolled control group of age-comparable, healthy subjects. Because certain individuals may be hypo-responsive to influenza vaccination, additional studies with high-risk groups are warranted in order to determine the optimal vaccine formulation and dosing schedule for prevention of novel H1N1 virus infection.
This is a phase III, randomized, controlled, open label study with two vaccine regimens. The study will assess the relative safety and immunogenicity of vaccine regimens comparing adjuvanted versus non-adjuvanted formulations of A(H1N1) inactivated influenza virus vaccine in subjects with Solid Invasive Tumors and to compare safety and immunogenicity data with a contemporaneously enrolled control group of age-comparable, healthy subjects. Because certain individuals may be hypo-responsive to influenza vaccination, additional studies with high-risk groups are warranted in order to determine the optimal vaccine formulation and dosing schedule for prevention of novel H1N1 virus infection.
