Clinical Trial Summary

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.

Description:

Participants will receive a single dose of their assigned vaccine during Visit 1. For those requiring two doses of influenza vaccine, as per Advisory Committee on Immunization Practices (ACIP) guidance, a second dose of the assigned vaccine will be administered at Visit 2. All participants will be followed up for safety (up to 6 months post final vaccination) and for immunogenicity up to Day 28 post-vaccination (Visit 2 or Visit 3, as appropriate).

• Any chronic illness that, in the opinion of the Investigator, is not well controlled and may interfere with trial conduct or completion, or with assessment of adverse events.

• Known seropositivity for human immunodeficiency virus, hepatitis B, or hepatitis C.

• Receipt of blood or blood-derived products (including immunoglobulin therapy) in the past 3 months, which might interfere with assessment of the immune response.

• Employees of the Investigator or study center, with direct involvement in the proposed study or other studies under the direction of that Investigator or study center, as well as family members of the employees or the Investigator.
