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.

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.
