A total of 1,761 healthy children will be randomized in a 2:1 ratio of LAIV to placebo.\n\nFor evaluation of efficacy, passive and active surveillance will be conducted weekly throughout the study to identify outcomes among vaccinated subjects. Children meeting the protocol-defined clinical case definition will have a nasal swab and throat swab specimen collected for testing by rRT-PCR for evidence of influenza virus infection.\n\n100 of the 1,761 participants were also included in a substudy designed to evaluate virologic evidence of LAIV replication. As such, nasal and throat swab specimens were collected on day 0 (prior to vaccination), as well as on post-vaccination days 2, and 4 from all subjects included in the substudy. These specimens will be tested for presence of wild-type and vaccine virus. Additionally, a more detailed assessment of vaccine reactogenicity will be made among these children by actively collecting solicited and unsolicited reactions at each study visit for the week post vaccination (days 2 and 4).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '71 Months', 'minimumAge': '24 Months', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Healthy male or female child at least 24 months of age and no older than 71 months of age at the time of study vaccination.\n* A child whose parent or guardian's primary residence, at the time of study vaccinations, is within the Niakhar DSS and who intends to be present in the area for the duration of the trial.\n* A child whose parent or legal guardian is willing to provide written informed consent prior to the participant's study vaccination\n\nExclusion Criteria:\n\n* Serious, active, medical condition, including: chronic disease of any body system,chronic infections such as tuberculosis, genetic disorders, such as Down's syndrome or other cytogenetic disorder, known or suspected disease of the immune system of any kind.\n* History of documented hypersensitivity to eggs or other components of the vaccine (including gelatin, sorbitol, lactalbumin and chicken protein), or with life-threatening reactions to previous influenza vaccinations.\n* History of Guillain-Barré syndrome.\n* Receipt of immunosuppressive agents, including systemic corticosteroids, during the month before planned study vaccination.\n* Receipt of aspirin therapy or aspirin-containing therapy within the two weeks before planned study vaccination.\n* History of any severe allergic reaction with generalized urticarial, angioedema, or anaphylaxis.\n* Receipt of an influenza vaccine within the past 12 months.\n* Has any condition determined by investigator as likely to interfere with evaluation of the vaccine or be a significant potential health risk to the child or make it unlikely that the child would complete the study.\n\nTemporary Contraindications:\n\n* Acute illness accompanied by a body temperature of 37.5°C or above (axillary measurement) within 14 days of enrollment visit.\n* Any acute respiratory infection within 14 days of enrollment visit.\n* Any illness accompanied by active wheezing within 14 days of enrollment visit."}, 'identificationModule': {'nctId': 'NCT01854632', 'briefTitle': 'Clinical Efficacy of Trivalent Live-Attenuated Influenza Vaccine (LAIV) Among Children in Senegal', 'organization': {'class': 'OTHER', 'fullName': 'PATH'}, 'officialTitle': 'A Randomized, Double-Blind, Placebo-Controlled Trial of the Clinical Efficacy of Trivalent Live-Attenuated Influenza Vaccine (LAIV) Among Children in Senegal', 'orgStudyIdInfo': {'id': 'LAIV-SEN-01'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'SIIL Live Attenuated Influenza Vaccine', 'description': 'Single 0.5 mL dose of trivalent live-attenuated influenza vaccine 2012/2013 Northern Hemisphere vaccine containing A/California/7/2009 (H1N1), A/Victoria/361/2011 (H3N2), B/Wisconsin/1/2010', 'interventionNames': ['Biological: SIIL Live Attenuated Influenza Vaccine']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Matched placebo', 'description': 'Single 0.5mL inactive placebo will be identical to reconstituted SIIL LAIV in ingredients and concentrations except A/California/7/2009 (H1N1), A/Victoria/361/2011 (H3N2), B/Wisconsin/1/2010 will be replaced with egg allantoic fluid.', 'interventionNames': ['Biological: Matched placebo']}], 'interventions': [{'name': 'SIIL Live Attenuated Influenza Vaccine', 'type': 'BIOLOGICAL', 'description': 'Trivalent live-attenuated influenza vaccine 2012/2013 Northern Hemisphere vaccine containing A/California/7/2009 (H1N1), A/Victoria/361/2011 (H3N2), B/Wisconsin/1/2010', 'armGroupLabels': ['SIIL Live Attenuated Influenza Vaccine']}, {'name': 'Matched placebo', 'type': 'BIOLOGICAL', 'description': 'Matched placebo will be identical to reconstituted SIIL LAIV in ingredients and concentrations except A/California/7/2009 (H1N1), A/Victoria/361/2011 (H3N2), B/Wisconsin/1/2010 will be replaced with egg allantoic fluid.', 'armGroupLabels': ['Matched placebo']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Niakhar', 'country': 'Senegal', 'facility': 'Institut de Recherche pour le Développement (IRD), Niakhar station', 'geoPoint': {'lat': 14.4817, 'lon': -16.39887}}], 'overallOfficials': [{'name': 'Aldiouma Diallo, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Institut de Recherche pour le Développement (IRD)'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'PATH', 'class': 'OTHER'}, 'collaborators': [{'name': 'Institut de Recherche pour le Developpement', 'class': 'OTHER_GOV'}, {'name': 'Institut Pasteur de Dakar', 'class': 'OTHER'}, {'name': 'Centers for Disease Control and Prevention', 'class': 'FED'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
