Estimating the effectiveness of seasonal vaccines against influenza related hospitalisation is important to guide these strategies. The main objective is to measure the population effectiveness of influenza vaccine in patients hospitalized with virologically confirmed influenza laboratory result during all influenza seasons from 2013/2014 to 2021/2022 in a French hospital network. An interim analysis is provided for each influenza season and a global analysis of all seasons.\n\nEach year, we also collect data from other respiratory viruses such as respiratory syncytial virus (RSV) on the hospitalized population. The data for three years confirm that, although RSV is less common than influenza in patients with flu-like symptom (4% of 1452 patients), it is responsible for serious complications at a higher frequency than influenza, especially in the elderly and immunosuppressed patients. To better understand the burden of disease of RSV infection in hospitalized adults, we need to start patients recruitment sooner at the start of the VRS epidemic.\n\nWith the recent emergence of the COVID-19 pandemic and our participation in European projects within the framework of COVID-19 surveillance, the FLUVAC study is an opportunity to collect additional data in patients hospitalized with a severe acute respiratory illness (SARI) which may be due to respiratory infection with an influenza virus or other respiratory viruses including SARS-CoV-2. We therefore propose to collect clinical (chronic diseases, comorbidities, intensive care), epidemiological and virological data throughout the year in adult patients hospitalized for suspected CO-VID-19.\n\nThis is a study "case-control" involving a nasopharyngeal sample for all hospitalised patients presenting a SARI within seven days. Cases will be patients RT-PCR positive for influenza. Controls will be patients negative for any influenza virus.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age ≥ 18 year\n* Affiliated with social security health insurance\n* Written informed consent\n* Patients hospitalized for at least 24 hours for one of the reasons indicated in Table 1 of protocol\n* Presence of Influenza-like syndrome before the hospitalization (even if symptoms are not present at the time of inclusion), or less than 48 hours after the hospitalization\n* Rapid completion of nasopharyngeal sample after hospitalization without exceeding 7 days after the onset of Influenza-like syndrome\n\nExclusion Criteria:\n\n* Realization of nasopharyngeal sampling more than 7 days after the onset of symptoms\n* Contraindication for influenza vaccine (Hypersensitivity to the active substances, to any of the excipients and to trace eg eggs, including ovalbumin, chicken protein)\n* Patients institutionalized without regular community interaction\n* Previously tested positive for any influenza virus in the current season (RT-PCR, multiplex RT-PCR)\n* Patient under curatorship or under guardianship whose sample was obtained as part of their medical care but not complying with the conditions of Article L1121-8 of the Code de la Santé Publique.\n* Patient under curatorship or under guardianship whose sample was not obtained as part of their medical care.'}, 'identificationModule': {'nctId': 'NCT02027233', 'acronym': 'FLUVAC EV-03', 'briefTitle': 'Clinical Trial to Assess the Influenza Vaccination of the Hospitalized Adults', 'organization': {'class': 'OTHER_GOV', 'fullName': 'Institut National de la Santé Et de la Recherche Médicale, France'}, 'officialTitle': 'Efficiency in Population of Influenza Vaccination for Flu Prevention of the Hospitalized Adults', 'orgStudyIdInfo': {'id': 'C13-47'}, 'secondaryIdInfos': [{'id': '2013-A01204-41', 'type': 'REGISTRY', 'domain': 'IDRCB'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Nasopharyngeal sample', 'description': 'Rapid completion of nasopharyngeal within 24 hours after hospitalization without exceeding 7 days after the onset', 'interventionNames': ['Other: nasopharyngeal sample']}], 'interventions': [{'name': 'nasopharyngeal sample', 'type': 'OTHER', 'description': 'The nasopharyngeal sample will be used to find the types and subtypes of influenza virus and other respiratory viruses (VRS, SARS-CoV-2 and others).', 'armGroupLabels': ['Nasopharyngeal sample']}]}, 'contactsLocationsModule': {'locations': [{'zip': '75654', 'city': 'Paris', 'country': 'France', 'facility': 'Institut National de la Santé Et de la Recherche Médicale', 'geoPoint': {'lat': 48.85341, 'lon': 2.3488}}], 'overallOfficials': [{'name': 'Odile Launay, PU-PH', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Assistance Publique - Hôpitaux de Paris'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Institut National de la Santé Et de la Recherche Médicale, France', 'class': 'OTHER_GOV'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
