Study Description

Brief Summary:

The aim of the study was to generate immunogenicity and safety data in the whole population to support registration of the Quadrivalent Influenza Vaccine (QIV) in India:

Primary objective:

• To describe in each age group the immune response induced by a single injection (participants aged >9 years) or 2 injections (participants aged 6 months to 8 years) of QIV.

Secondary objective:

• To describe in each age group the safety profile of QIV.

Condition or disease	Intervention/treatment	Phase
Influenza	Biological: Quadrivalent Inactivated Influenza Vaccine (2016-2017 NH formulation), No Preservative; Biological: Quadrivalent Inactivated Influenza Vaccine (2016 SH formulation), No Preservative; Biological: Quadrivalent Inactivated Influenza Vaccine (2015-2016 NH formulation), No Preservative; Biological: Quadrivalent Inactivated Influenza Vaccine (2015 SH formulation), No Preservative	Phase 3

Detailed Description:

All participants were vaccinated with the QIV (split-virion, inactivated) Northern Hemisphere (NH) or Southern Hemisphere (SH) formulations by the intramuscular (IM) route. Immunogenicity of the vaccine was assessed at baseline (Day 0) and 28 days after the last injection. Safety data were collected up to 28 days after each injection. Serious adverse events (SAEs) were collected throughout the trial.

Outcome Measures

Primary Outcome Measures :

1. Geometric Mean Titers (GMTs) of Influenza Vaccine Antibodies [ Time Frame: Day 0 (pre-vaccination) and 28 days post-final vaccination (post-vaccination) ]
   Anti-influenza antibodies were measured using hemagglutination inhibition (HAI) assay for 4 strains: H1N1, H3N2, B Victoria, B Yamagata.
2. Number of Participants With Seroprotection to Influenza Vaccine Antigens [ Time Frame: Day 0 (pre-vaccination) and 28 days post-final vaccination (post-vaccination) ]
   Anti-influenza antibodies were measured using HAI assay for 4 strains: H1N1, H3N2, B Victoria and B Yamagata. Seroprotection was defined as an antibody titer >=40 (1/dilution[dil]) at pre-vaccination and at post-final vaccination.
3. Number of Participants With Seroconversion or Significant Increase to Influenza Vaccine Antigens [ Time Frame: 28 days post-final vaccination (post-vaccination) ]
   Anti-influenza antibodies were measured using HAI assay for 4 strains: H1N1, H3N2, B Victoria and B Yamagata. Seroconversion was defined as pre-vaccination titer <10 (1/dil) and post-vaccination titer >=40 (1/dil), and Significant increase was defined as pre-vaccination titer >=10 (1/dil) and >= 4-fold increase of post-vaccination titer.

Secondary Outcome Measures :

   1. Solicited injection site reactions:

      • Age 6-23 months: Tenderness, Erythema and Swelling(Grade 3: Tenderness: cries when injected limb is moved; Erythema and Swelling:>=50 mm)
