Filter by:Haemophilus influenzae serotype a (Hia) has emerged as a leading cause of serious illness in Indigenous children in Canada and Alaska in recent decades. In hospital-based surveillance studies, Hia was the most common cause of invasive disease, resulting in morbidity or mortality after Haemophilus influenzae serotype b (Hib). Given the success of the Hib vaccine program and the pathophysiologic similarities between Hib and Hia, immunization is the obvious way to protect Indigenous children living in small and scattered communities. The Public Health Agency of Canada has been working with the National Research Council and other members of the Consortium, including the Canadian Immunization Research Network, McGill Interdisciplinary Initiative in Infection and Immunity, GlycoNet, the Hewitt Foundation, and Inventprise/InventVacc, to develop a Hia vaccine for prevention of this deadly infection. The engagement process initiated by NRC with Consortium members and representatives from Indigenous groups, particularly, has led to the current project plan. In this first-in-human study, we propose investigating the safety and immunogenicity of a novel glycoconjugate candidate vaccine that uses protein carrier CRM197 in healthy adults in the general population. The study will be conducted at the McGill University Health Center Vaccine Study Centre in Montreal and the Canadian Center for Vaccinology in Halifax. The findings of this Phase I study will be necessary to effectively move this potential vaccine solution further along the development continuum.
This project uses questionnaires to statistically analyze whether influenza vaccination is protective for young children.
The purpose of this study is to learn if modified RNA (modRNA) vaccines for the prevention of influenza are: - safe; and - how these vaccines produce an immune response in generally healthy adults. Immune response is the way the body protects itself against things it sees as harmful or foreign. RNA (also called ribonucleic acid) is one of two types of nucleic acid made by cells. RNA contains information that has been copied from DNA (the other type of nucleic acid). Cells make several different forms of RNA, and each form has a specific job in the cell. Many forms of RNA have functions related to making proteins. RNA is also the genetic material of some viruses instead of DNA. RNA can be made in the laboratory and used in research studies. Also called ribonucleic acid. Influenza is term used for flu illness. It is an infection caused by a virus that affects your mouth, nose, and throat. The study is seeking for participants who: - are at least 18 years of age - have not received an influenza vaccine within the last 6 months - are generally healthy This study will be divided into three sub-studies: Substudy A (SSA), Substudy B (SSB), and Substudy C (SSC). All participants, regardless of sub-study, will receive 1 dose of either of the following vaccines as an injection into their arm: - 1 of the modRNA influenza vaccines that is being studied; or - an approved influenza vaccine approved for use in their respective age group. Participants will be involved in this study for about 6 months. During this time, participants will have at least 3 clinic visits.
The purpose of this study is to assess the safety and immune response of GlaxoSmithKlines (GSK) messenger RNA (mRNA)-based multivalent vaccine (GSK4382276A) candidate against influenza, administered in healthy younger adults (YA) and older adults (OA).
The aim of this study is to evaluate the safety, reactogenicity and immunogenicity of the Flu Pandemic messenger RNA (mRNA) vaccine (including dose-finding and dose-confirmation) administered healthy adults 18 to 85 years of age.
The purpose of this study is to evaluate the safety and immunogenicity of a single intramuscular (IM) injection of different formulations of Quadrivalent Influenza Vaccine (QIV) messenger ribonucleic acid (mRNA) (MRT5421, MRT5424, and MRT5429) compared to an active control (QIV- standard dose (SD), QIV- high dose (HD) [adults ≥ 65 years of age only], or quadrivalent recombinant influenza vaccine (RIV4)) in adults 18 years of age and older.
The goal of this Phase II/III study is to investigate the safty and efficacy of ADC189 tablets in adolescents and adults with influenza A virus infection/influenza B virus infection. The main aim to answer: - Phase II study is to evaluate the efficacy of ADC189 tablets in the treatment of adult influenza subjects and determine the optimal therapeutic dose by analyzing the time of virus titer turning to negative. All the results will be used to design the Phase III study. - Phase III study is to evaluate the efficacy of ADC189 tablets by analyzing the duration of remission of all influenza symptoms in adolescents and adults subjects with influenza. Participants will be taken ADC189 teblets/Placebo once, and be observed by 22 days. Phase II study has 3 groups: 15 mg ADC189; 45 mg ADC189; and Placebo; Phase III study has 2 groups: 45 mg ADC189; and Placebo.
To evaluate the safety of administering 1 or 2 doses of the quadrivalent influenza virus split vaccine (MDCK cells) (0.5ml/dose) in individuals aged 6 months and above.
The goal of this randomized, double-blind, placebo-controlled clinical trial is to investigate the immunological effects of influenza vaccination outside of the influenza season on arterial inflammation in patients with a recent acute myocardial infarction (AMI). The primary objective is to compare the effects of influenza vaccination to those of a placebo in reducing post-myocardial infarction coronary inflammation as measured by coronary computed tomography angiography (CCTA). The main questions it aims to answer are: Does influenza vaccination reduce arterial inflammation as measured by CCTA at week 8 after percutaneous coronary intervention (PCI) in comparison to baseline? Does influenza vaccination modulate systemic inflammation as measured by blood biomarkers and in-vitro challenge tests at week 8 after PCI in comparison to baseline? Researchers will compare the effects of influenza vaccination with those of a placebo.
The study is planned to evaluate the therapeutic efficacy and safety of Ingavirin®, capsules, 60 mg, in the treatment of influenza or other acute respiratory infections in children from 13 to 17 years compared with placebo.
