  • Administration of immunoglobulin and/or any blood products within the 3 months preceding vaccination, or planned administration during the study.

Arm Type

Experimental

Active Comparator

Arm Label

Seqirus Quadrivalent Inactivated Influenza Vaccine

Comparator Quadrivalent Influenza Vaccine

Arm Description

The Seqirus study vaccine is a sterile, thimerosal-free suspension containing 60 mcg total hemagglutinin antigen per 0.5 mL dose (15 mcg each of the four recommended influenza strains for the Northern Hemisphere 2015/2016 influenza season).

The comparator Quadrivalent Inactivated Influenza vaccine is a US-licensed product containing four recommended influenza strains for the Northern Hemisphere 2015/2016 influenza season.

Outcomes

Primary Outcome Measures

The Geometric Mean Titer (GMT) Ratio of Each Virus Strain.
Noninferiority of Seqirus QIV compared to comparator QIV was assessed by the eight co-primary endpoints of hemagglutination inhibition (HI) antibody geometric mean titer (GMT) and seroconversion rate (SCR) for each viral strain included in the vaccines. The GMT ratio is defined as the geometric mean of the postvaccination HI titer for the US-licensed comparator QIV over the geometric mean of the postvaccination HI titer for Seqirus QIV.
The Difference in Seroconversion Rate (SCR) for Each Virus Strain.
Noninferiority of Seqirus QIV compared to Comparator QIV was assessed by the eight co-primary endpoints of HI geometric mean titer (GMT) and seroconversion rate (SCR) for each viral strain. The rate of SCR is defined as the percentage of subjects with either a prevaccination HI titer < 1:10 and a postvaccination HI titer ≥ 1:40, or a prevaccination HI titer ≥ 1:10 and a ≥ 4-fold increase in postvaccination HI titer. For the SCR comparison, the difference between the SCR for each virus strain will be determined.

Secondary Outcome Measures

Safety Endpoint: The Frequency and Severity of Solicited Local Adverse Reactions.
Frequency and severity of solicited local adverse reactions (AEs) for 7 days (ie, day of vaccination and 6 subsequent days) after each vaccination dose
Safety Endpoint: The Frequency and Severity of Solicited Systemic Adverse Events (AEs).
Frequency and severity of solicited systemic adverse events (AEs) for 7 days (ie, day of vaccination and 6 subsequent days) after each vaccination dose
Safety Endpoint: The Frequency of Cellulitis-like Reaction.
Frequency of cellulitis-like reaction for at least 28 days after each vaccination dose
Safety Endpoint: The Frequency and Severity of Unsolicited Adverse Events (AEs).
Frequency and severity of unsolicited AEs for at least 28 days (ie, day of vaccination and 27 subsequent days) after each vaccination dose
Safety Endpoint: The Frequency of Serious Adverse Events (SAEs).
Frequency of serious adverse events (SAEs) for 180 days after the last vaccination dose.
Immunogenicity Endpoint: GMTs - Geometric Mean of HI Titers Prevaccination (Day 1) and Postvaccination (Study Exit Visit)
The humoral immune response was assessed for Seqirus QIV & comparator QIV. Serum HI titers against the 4 influenza vaccine strains was used to calculate: - Geometric mean of HI titers prevaccination & postvaccination
Immunogenicity Endpoint: Seroconversion Rate (SCR)
The humoral immune response was assessed for Seqirus QIV & comparator QIV. Serum HI titers against the 4 influenza vaccine strains was used to calculate: - SCRs: % of subjects with either a prevaccination HI titer < 1:10 and a postvaccination HI titer ≥ 1:40 or a prevaccination titer ≥ 1:10 and a ≥ 4-fold increase in postvaccination titer
Immunogenicity Endpoint: Seroprotection Rate
The humoral immune response was assessed for Seqirus QIV & comparator QIV. Serum HI titers against the 4 influenza vaccine strains was used to calculate: - The % of subjects with a titer ≥40 (seroprotection rates) at Day 1 and at Exit Visit
Immunogenicity Endpoint: Geometric Mean Fold Increase (GMFI)
The humoral immune response was assessed for Seqirus QIV & comparator QIV. Serum HI titers against the 4 influenza vaccine strains was used to calculate: - Geometric mean fold increase (GMFI): geometric mean fold titer rise from Day 1 to Exit Visit
