Active clinical trials for "Influenza, Human"

This Phase 2a clinical trial is designed to evaluate the immunogenicity and the safety of one administration of OVX836 influenza vaccine at different dose levels (180µg, 300μg and 480μg) in order to assess the dose response of the OVX836 influenza vaccine.

This trial by its design was a prospective, multicenter, double blind, randomized comparative clinical trial of the IIIb-IV phase which was carried out in parallel groups of volunteers over the age of 60

This Phase 2, randomized, observer-blind, active controlled clinical study is evaluating the safety and immunogenicity of the investigational MF59-Adjuvanted Quadrivalent Subunit Inactivated Influenza Vaccine. Approximately 480 subjects are to be randomized into 1 of 4 possible treatment groups (investigational Influenza Vaccine or licensed Quadrivalent Influenza Vaccine comparators) at 120 participants per group. Every participant will receive an influenza vaccine injection on Day 1 and will be followed up for approximately 6 months following injection. The primary immunogenicity analysis is based on Day 29 serum.

This is a Phase 2, randomized, double-blind, placebo-controlled study of INNA-051 in healthy adults, administered prior to administration of an influenza challenge virus. This study will evaluate 2 active dose levels of INNA-051 and placebo.

Biotherapies have significantly improved the prognosis of rheumatoid arthritis (RA), particularly anti-TNF. However, these molecules are associated with a well-demonstrated increase in infectious risk, including an over-risk of pneumococcal and influenza infection.. Therefore, when initiating anti-TNF treatments, it is recommended to update the vaccination schedule of these patients, to vaccinate them against pneumococcus and carry out an annual anti influenza vaccination.. However, vaccination coverage remains sub-optimal. The means to improve this vaccination coverage are multiple but often require human resources. Medical teams often lack time, nursing interventions are effective but again requires the availability of the health care team. The use of modern digital means (automatic reminders) is an attractive alternative to increase immunization coverage without the use of medical or paramedical time. The objective of the study is to evaluate the effectiveness, in terms of immunization coverage, of SMS and/or email reminders reminding the need to vaccinate against seasonal influenza compared to usual care, in patients with RA on biotherapies participating in the e-cohort of the French ART Registry (NCT03062865). This study will be based on the ART Registry e-cohort. This will be a randomized controlled trial in patients in the ART e-cohort. The patients will be allocated in one of the 2 arms : one arm receiving reminders by email and SMS of the influenza vaccination, the other arm with absence of reminders. This study will be conducted during the annual French National communication campaign to encourage influenza vaccination. The main evaluation criterion will be the influenza vaccination coverage rate at the end of the vaccination campaign. It will be compared between the two arms.

Study to assess the efficacy and safety of a multiple dose regimen and a single dose regimen of intranasal Neumifil, administered prior to challenge with Influenza virus in healthy adult participants

The purpose of this study is to assess, prospectively, the effect on flu vaccination rates of salient alerts in the electronic health record that indicate a patient's high risk for flu and its complications. The investigators hypothesize that the salient alerts will lead to increased flu vaccination compared with a standard flu alert.

Comparative trial of tolerability, reactogenicity, safety and immunogenicity of the Flu-M vaccine as compared to the Vaxigrip® vaccine in terms of prevention of influenza in children aged 6 months to 9 years (at the time of the first vaccination).

This study is an open-label,single center phase Ⅳ clinical trial of combined immunization with quadrivalent influenza vaccine and 23-valent pneumococcal polysaccharide vaccine.The purpose of this study is to evaluate the safety and immunogenicity of combined immunization with quadrivalent influenza vaccine and 23-valent pneumococcal polysaccharide vaccine in the elderly aged 60 years and above.

The primary objectives of this study are to evaluate the humoral immunogenicity of mRNA-1010 relative to that of an active comparator against vaccine-matched influenza A and B strains at Day 29, and to evaluate the safety and reactogenicity of mRNA-1010.
