Active clinical trials for "Influenza, Human"

Influenza (the flu) is a leading cause of respiratory (breathing) illness that leads to sickness and death during the winter months. A better understanding of why certain people get the flu or get sicker with the flu than other people is important for developing improved vaccines and treatments. This study will look at the genetic makeup (determines each person's specific characteristics and traits) of 50 patients, older than 50, who were hospitalized with flu at Vanderbilt University during the 2006-2007 flu season. Their genetic makeup will be compared with the genetic makeup of 50 people who are not related but were in close daily contact with the flu patient and were not infected with flu virus. The study staff will collect a blood sample (contains genetic material) from each participant (flu patients and their contacts) for comparison. Flu patients will have completed a health survey as part of the previous study, and their contacts will complete a shorter version of this survey.

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™.

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 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

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.

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.

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.
