Active clinical trials for "Influenza, Human"

Influenza is an important public health problem. Organ transplant patients are particularly susceptible to severe disease. Also, they shed higher quantities of virus for longer durations, leading to greater contagious potential, thereby potentially serving as nodes of spread in the community. Therefore, improved strategies to prevent influenza in this population is an important public health concern. Standard vaccination is poorly immunogenic post-transplant and new vaccine strategies are needed. Adjuvanted vaccines contain molecules that create a strong local inflammatory response and they attract immune cells to the site of injection, increasing the immunogenicity of the vaccine antigen. Recently seasonal influenza vaccines containing adjuvants have become available in Canada but have only limited information in transplant patients. This randomized trial is designed to assess the immunogenicity of an adjuvanted vaccination strategy compared to a standard vaccine for seasonal influenza in a cohort of adult organ transplant recipients.

This study will investigate the incidence of influenza, disease and various possible downstream complications and hospitalizations or emergency room visits after routine annual vaccination of the elderly population with Fluarix™.

The study is designed to evaluated if adjuvanted vaccine elicits higher T cell and B cell responses than non-adjuvanted standard dose influenza vaccine in nursing home residents.

This study aims to test the hypothesis that gene transcriptional changes occur within 24 hours of virus exposure in the blood and nasal mucosa, and to identify early biomarker signatures that are predictive of higher viral shedding at the peak of disease

This study is a randomized controlled trial (RCT) comparing adjuvanted influenza vaccine (AV) to unadjuvanted inactivated influenza vaccine (IIV). Children in Hutterite colonies in Alberta and Saskatchewan will receive AV or IIV. The goal of this study is to determine whether the AV vaccine, can provide increased community-wide protection.

The main aim of research is to determine of the prevalence of influenza virus and influenza vaccination coverage rate among hospital and GPs healthcare workers. Course of research: Participation in the study is voluntary and carried out after the consent of the examined person. The examination consists of: 1) completing the questionnaire and 2) taking the throat swab twice by the researcher. Two throat swab samples will be taken at the same time. Both samples will be used for virological examination to determine the presence of influenza virus material using non-invasive tests: one sample will be analyzed by a quick 'on-site' test - Flu SensDx kit, while the other sample will be transported to the laboratory, where the reverse transcriptase polymerase chain reaction (RT-PCR) - reference method - will be performed to confirm the presence of influenza genetic material. Swabs are planned to be collected during the 2019/2020 influenza epidemic season (January-March). In the last stage of the study, the results obtained from the survey questionnaire and the results of virological tests will be subject to statistical analysis and based on the data obtained, conclusions will be drawn from the study, indicating their practical application. The results obtained from this study will be used to develop a quality improvement program to control influenza virus infection, which will improve the safety of both patients and medical staff.

This study mainly focused on the effect of early antiviral treatment on the duration of cough in influenza patients.investigators conducted an early investigation of patients with positive influenza virus and asked whether patients used antiviral drugs in the early stages. According to the use of drugs, patients were divided into oral oseltamivir group, oral lotus phlegm group and other groups, and investigators will collected Inspection information and medication status,during the treatment period of patients.

The purpose of the study on the Prevention of Influenza and Other Wintertime Respiratory Viruses among Healthcare Professionals in Israel Effectiveness of Influenza Vaccine in Preventing Influenza Virus Infection, Missed Work, and Patient Exposure: A Prospective Cohort Study of Healthcare Personnel (to be called the Healthcare Personnel or HCP study throughout this Data Security Plan) is to investigate vaccine effectiveness and respiratory illness among healthcare personnel (HCP). This will help to better understand the factors that influence influenza vaccination choice, individual vaccine response, and whether or not the influenza vaccine helps to prevent influenza in HCP.

This project is to assess the immunogenicity, safety and overall survival impact of intramuscular injection of trivalent influenza vaccine in non-small cell lung cancer (NSCLC) patients with PD-1/PD-L1 inhibitor treatment.

Many people worldwide received the monovalent adjuvanted H1N1 vaccine. However, very little is known about the safety of the vaccine, particularly beyond the first few weeks after vaccination. This study will combine data from a well-established immunization registry in Manitoba with data from hospitalization and physician records, to examine the safety of the vaccine in the six month period post-vaccination. Studies on vaccine safety are important as the public's perception of the safety of a vaccine has a major role in its uptake.
