To trial the reactogenicity, safety and immunogenicity of the Flu-M inactivated split influenza vaccine in volunteers aged 18-60 years
Viral respiratory tract infections (VRTI) are among the most common human illnesses, impacting billions globally. There is an unmet need to identify novel ways to detect, treat and prevent their spread. New wearable devices could address this need, using special biosensors worn by patients. This is a single centre, controlled, before and after, longitudinal, clinical trial. Participants will receive FluMist, a live attenuated influenza vaccine, which will act as a proxy to a viral respiratory tract infection and create a very minor response to the immune system. Vital signs and activity levels will be monitored continuously using wearable biosensors for 7 days prior to and 7 days following, along with symptom tracking and blood tests to measure immune responses. Artificial intelligence (AI) and machine learning (ML) algorithms will be used to analyse the data. AI and ML will identify subtle changes in vital signs and activity levels from the immune response to respiratory viruses. These data will help develop future methods to address important public health questions related to respiratory virus detection, containment and management. The purpose of this study is to explore whether wearable sensors can detect, track the progress and recovery from viral respiratory tract infection.
The present study will evaluate the concomitant administration of a Quadrivalent Inactivated Influenza Vaccine with the highest dose level of OVX836 (480µg) tested in the clinic to date, for which the likelihood for interference with Quadrivalent Inactivated Influenza Vaccine is considered the highest.
This study aims to evaluate the safety and reactogenicity profile of CVSQIV at different dose levels.
In this single-center, randomized, blinded, positive-controlled design, the investigators will assess the safety and immunogenicity of 2 doses of an inactivated quadrivalent influenza vaccine in children aged 6 to 35 months. About 120 healthy participants are planned to be enrolled, of who 60 participants were enrolled in the low-dose group and 60 participants were enrolled in the high-dose group. In the low-dose group, participants were randomly (2:1:1) assigned to receive a quadrivalent inactivated influenza vaccine (IIV4) at 0.25 mL including A/H1N1, A/H3N2, B/Victoria, and B/Yamagata, and a trivalent inactivated influenza vaccine (IIV3) at 0.25 mL including A/H1N1, A/H3N2 and B/Victoria, and IIV3 at 0.25 mL including A/H1N1, A/H3N2, and B/Yamagata. In the high-dose group, participants were randomly (2:1:1) assigned to receive IIV4 at 0.5 mL, and IIV3 at 0.25 mL including A/H1N1, A/H3N2, and B/Victoria, and IV3 at 0.25 mL including A/H1N1, A/H3N2, and B/Yamagata. Subjects receive 2 doses of influenza vaccine 4 weeks apart. The occurrence of adverse reactions within 30 minutes, the occurrence of adverse reactions within 28 days, and serious adverse events within 6 months after vaccination will be observed in all participants. For participants aged 24-35 months in each dose group, laboratory safety tests were measured before enrollment and on day 4 post each dose to assess any toxic effects. In addition, all subjects will be required to collect blood for HI antibody testing before the first dose of vaccination and 30 days after the second dose of vaccination.
This Prospective epidemiological cohort study is being conducted in order to generate epidemiological data in support of Osivax's clinical development of a broad spectrum influenza vaccine based upon the internal influenza nucleoprotein (NP) as a target for immune response.
The study the safety, reactogenicity and obtain preliminary data on the immunogenicity of Flu-M Quadro, 4-valent inactivated split influenza vaccine, in healthy volunteers
Study of the Reactogenicity, Safety and Immunogenicity of Flu-M Inactivated Split Influenza Vaccine in Volunteers Aged 18-60 Years
Assessment of the effect reached with the different doses of AV5080 on the duration and severity of influenza symptoms based on the incidence of their resolution within 96 hours from study treatment initiation compared to Placebo. The absence of influenza symptoms or their reduction to mild severity for at least 24 hours indicates the resolution of influenza.
