Official title
Safety and Immunogenicity Among Children Administered Quadrivalent Influenza Vaccine
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The aim of the study is to evaluate a prototype quadrivalent influenza vaccine (QIV), the licensed 2010-2011 trivalent influenza vaccine (TIV) containing the primary B strain (B1), and the investigational TIV containing the alternate B (B2) strain in children. Primary Objective: To demonstrate non-inferiority of antibody responses to QIV compared with licensed 2010-2011 TIV (containing the primary B strain) and investigational TIV (containing the alternate B strain) as assessed by geometric mean titer (GMT) ratios for each of the four virus strains separately among children aged 6 months to less than 9 years of age Secondary Objective: To demonstrate superiority of antibody responses to each B strain in QIV compared with antibody titers following vaccination with the TIV that does not contain the corresponding B strain, as assessed by GMT ratios and seroconversion rates. Observational Objective: To describe the safety profile of QIV among subjects 6 months to less than 9 years of age, as assessed by solicited injection site and systemic adverse events (AEs) collected for 7 days post-vaccination, unsolicited adverse events collected from 21 days post-vaccination, and adverse events of special interest and serious adverse events (SAEs) collected from Visit 1 to Visit 2.
