Filter by:Subjects will be recruited and divided into 3 groups: 1. Experimental Group (378 subjects): combined immunization of EV71 vaccine and influenza vaccine; 2. Control Group A (378 subjects): EV71 vaccine only; 3. Control Group B (378 subjects): influenza vaccine only; All blood samples will be collected before and one month after vaccinatioin. The immunogenicity and safety of both experimental and control groups will be compared and the data be analyzed.
The occurence of influenza can be a factor of imbalance of asthma. Asthma patients are recommended for annual influenza vaccination . However there is insufficient vaccination coverage of asthmatic patients despite this recommendation. The aim of this study is to evaluate the rate of influenza vaccination coverage of children with asthma aged from 6 month to 17 years of age followed in pediatric pneumology consultation at the university hospital of Nancy.
As yet the investigators do not understand if there are biomarkers of immune protection after the Flumist or Live Attenuated Flu Vaccine (LAIV). Here the investigators test the hypothesis that the T-bet expressing fraction of flu-specific B cells after live attenuated influenza vaccination also serves as an early biomarker of long-lived antibody responses after vaccination. In this study the investigators will be providing the LAIV to up to 10 healthy subjects and assaying their immune response and then providing the intramuscular influenza vaccination and testing to see if the immune protection after the LAIV also protects after the intramuscular influenza vaccination. Update: We have amended this protocol to study the antigen-specific B cell populations that circulate after LAIV or IIV prime and LAIV or IIV boost.
Invasive tracheobronchial aspergillosis (ITBA) is an uncommon, but severe clinical form of Invasive Pulmonary Aspergillosis (IPA) in which the fungal infection is entirely or predominantly confined to the tracheobronchial tree. In view of the limited data concerning critically ill patients admitted to the intensive care unit (ICU) with severe influenza associated with ITBA, the investigators decided to evaluate the differences between the clinical presentations of two invasive infections: ITBA and IPA without tracheobronchial involvement (No ITBA).
This phase 3 clinical study is a randomized, observer-blind, comparator-controlled, multicenter study of QIVc versus a US-licensed comparator QIV in children 6 months through 47 months of age. The purpose of this study is to demonstrate that vaccination with QIVc elicits an immune response that is noninferior to that of a US-licensed comparator QIV containing the same virus strains, in children 6 months through 47 months of age.
The purpose of the study is to evaluate immunogenicity and safety of three different doses of candidate hexvalent vaccine in comparison to co-administration of EupentaTM Inj. and Imovax® Polio in separate injections at four weeks after completion of three-dose primary series at 6-10-14 weeks of age when administered to healthy infants and thereby to select the optimal dose of candidate vaccine
A prospective, open-label, interventional phase IV study to assess the safety of EupentaTM Inj.{fully liquid pentavalent vaccine, Adsorbed Diphtheria-Tetanus-whole-cell Pertussis-Hepatitis B (rDNA [recombinant-deoxyribonucleic acid])-Haemophilus influenzae type b conjugate vaccine}
The purpose of the study is to compare Emergency Department patients who undergo influenza and RSV PCR testing using an FDA-approved point-of-care device (Cepheid Xpert® Xpress Flu/RSV) located in the ED, to patients who undergo influenza and RSV PCR testing at the core laboratory. The principal purpose is to determine if the time spent in the ED is different in the group undergoing POC influenza testing compared to those undergoing laboratory-based influenza testing.
This is a study of a reverse-engineered, Good Manufacturing Practice (GMP) grade, antiviral-sensitive, influenza A/Bethesda/MM2/H1N1 virus (A/California/04/2009/H1N1-like) infection to assess the effect of pre-existing immunity on clinical and immunological responses. Up to 80 healthy adult subjects will undergo intranasal inoculation with A/Bethesda/MM2/H1N1 virus, and their clinical manifestations, viral shedding and immunological responses will be characterized. The Primary Objective for this study is to evaluate the association of symptomatic Reverse Transcription-Polymerase Chain Reaction (RT-PCR)-positive influenza virus infection post-challenge and pre-existing Hemagglutinin Inhibition Test (HAI) antibody titers.
This is a Phase 2b, multi-center, double-blind, randomized, placebo-controlled, parallel-group study of NKT versus placebo in otherwise healthy adults presenting with acute uncomplicated ILI due to influenza or other respiratory viruses in a community setting.
