Filter by: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 purpose of the current study is to assess the effectiveness of protein-based COVID-19 or influenza vaccines when given individually or together via oral/ sublingual mucosal route instead of intramuscular delivery. The comparator will be a seasonal influenza vaccine which will also be administered with Advax-CpG adjuvant via the oral route. This study will use a cross-over design and everyone in the study will over a space of about 4 months receive both the COVID-19 and influenza vaccines.
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.
Flu vaccination, as well as being effective to prevent seasonal influenza, decreases staff illness and absenteeism and reduces costs resulting from loss of productivity. Despite the effectiveness of flu vaccination, the seasonal coverage among healthcare workers is usually low. The aim of this retrospective observational study is to analyze the vaccination coverage rate among all employees (healthcare workers and administrative staff) of a large teaching hospital in Rome during the 2017-2018 influenza season, to perform a cost-consequence analysis of influenza vaccination (by evaluating the absenteeism due to illness in the epidemic period), and to assess the impact of vaccination in terms of both costs and sick days.
In this work, we are assessing the impact of messaging with or without a $50 financial incentive on influenza vaccination rates in a county health system. Our main hypothesis is that a message with a $50 financial incentive will increase vaccination rates relative to a control/"treatment as usual" group. We further hypothesize that the financial incentive will increase vaccination rates relative to the message only arm.
The effect of LiteVax Adjuvant supplemented to licensed seasonal influenza vaccine on safety and immunogenicity will be investigated in both younger and older healthy participants. Local and systemic adverse events, and humoral and cellular immune responses will be determined at different time intervals after a single administration. Mode of action of LiteVax Adjuvant will examined by detailed genetic analysis and omics approaches such as transcriptomics, proteomics and metabolomics.
The goal of this Phase 3 study is to compare the effectiveness, safety, and side effects of the CIC vaccine with approved flu vaccines and the Novavax COVID-19 Vaccine with adjuvant.
