Brief Summary

The main purpose of this trial is to describe the product profile in terms of immunogenicity and safety following administration of trivalent influenza vaccine (split-virion, inactivated) produced at Shenzhen (SP Shz TIV).

Primary objective:

• To describe in each group the immune response induced by a single dose (subjects aged ≥ 3 years) or by two doses (subjects aged 6 to 35 months) of SP Shz-TIV.

Secondary objective:

• To describe in each group the safety profile of the vaccine after a single dose (subjects aged ≥ 3 years) or after each and any dose administered (subjects aged 6-35 months).

Detailed Description

Healthy subjects will be included to receive one or two doses of SP Shz TIV The study will assess the immunogenicity and safety of a single dose (in subjects from 3 years) or two doses of SP Shz TIV vaccine given 28 days apart (pediatric population from 6 to 35 months).

• For subjects aged 6-35 months only: Previous vaccination against influenza (i.e. 2 consecutive doses of influenza vaccine [same seasonal strain composition]) any time prior to study enrollment or history of prior exposure to influenza virus through natural infection
• Vaccination against influenza given in the past 6 months with any influenza vaccine or planned receipt of influenza vaccination during the present study
• Receipt of immune globulins, blood or blood-derived products in the past 3 months, which might interfere with assessment of the immune response
