Active clinical trials for "Influenza, Human"

A multi-centre, randomized, placebo controlled, trial. Participants at high-risk for vascular events from the network of INTER- CHF will be randomized to inactivated influenza vaccine or placebo and followed prospectively over three influenza seasons. 5,000 participants will be enrolled prior to influenza season, randomized to either influenza vaccine or saline placebo, either of which they will receive annually for three years and then followed over each of the influenza seasons.

The primary purpose of this study is to validate the sensitivity and specificity of the Respirio Flu Test and the eLab Flu Test in detecting Influenza A as compared to the gold standard for detection, Reverse Transcriptase Polymerase Chain Reaction (RT-PCR). The secondary aims are to: Validate the sensitivity and specificity of the Respirio Flu Test and the eLab Flu Test in detecting Influenza B as compared to the gold standard for detection, Reverse Transcriptase Polymerase Chain Reaction (RT-PCR); Evaluate the correct interpretation of the Respirio Flu Test by subjects with influenza-like symptoms; Evaluate the subjects' satisfaction with the convenience, comfort and ease of use of the Respirio Flu Test.

The immunogenicity of simultaneous administration of quadrivalent influenza vaccine and pneumococcal vaccine was unknown. The purpose of present study is to compare the immunogenicity of simultaneous administration of influenza vaccine and pneumococcal vaccine with that of separate administration.

Although clinical presentation of influenza is often symptomatic, asymptomatic cases also occur. The knowledge of the incidence of asymptomatic influenza among healthcare workers is very important because of the risk of cross-transmission to hospitalized patients. The principal objective of the study is to estimate the incidence of symptomatic and asymptomatic influenza among healthcare workers in short-stay wards. The results of this study will lead to a better understanding of the burden of asymptomatic influenza among healthcare workers and might be used as an argument to increase influenza vaccine coverage among healthcare workers.

A Pilot Study utilizing high dose trivalent influenza vaccine dose in a booster dosing schedule for patients with monoclonal gammopathies stratified by disease status

The purpose of this study is to evaluate the antibody response to each of the three influenza vaccine strains included in the licensed seasonal flu vaccine, as measured by hemagglutination inhibition (HAI) at 21 days post immunization in non-elderly and elderly subjects in compliance with the requirements of the current European Union (EU) recommendations for the evaluation of the immunogenicity for a new formulation of a licensed flu vaccine (CPMP/BWP/214/96).

Influenza is a frequent cause of fever in returning travelers. Usually diagnosis rests on the clinical picture. Rapid flu tests are becoming increasingly popular, although their sensitivity and specificity are suboptimal. The objective of this study is to evaluate if rapid flu tests influence the medical management of returning travelers with fever, a population at intermediate risk for influenza infections.

The main objective of the study is to assess the immune response to a non-adjuvanted H5N1 influenza vaccine in an adult population when administered according to a single prime-boost schedule.

Trial for annual approval of interpandemic influenza vaccines

To assess whether CAIV-T was transmitted from vaccinated children to their unvaccinated contacts in a day care setting; and if so, to estimate the rate of transmission.
