Humoral and Cell Mediated Immunity and Safety of MF59C.1-adjuvanted Subunit Influenza Vaccine or a Conventional Subunit Influenza Vaccine in Previously Unvaccinated Healthy Subjects
A Phase II, Randomized, Controlled, Observer-Blind, Clinical Study to Evaluate the Humoral and Cell Mediated Immunity and Safety of Two Intramuscular Doses of MF59C.1-adjuvanted Subunit Influenza Vaccine or Conventional Subunit Influenza Vaccine in Previously Unvaccinated Healthy Subjects Aged 6 to <36 Months

Brief Summary
This study aims to evaluate the immunogenicity, by means of cell mediated immunity (CMI) and hemagglutination inhibition (HI) assay, and also the safety of a MF59C.1-adjuvanted subunit influenza vaccine compared with a conventional subunit vaccine in previously unvaccinated children aged 6 to \<36 months.

Outcome Measures
Primary Outcomes (2)
Cell Mediated Immune (CMI) Responses After In-vitro Restimulation Of Peripheral Blood Mononuclear Cells (PBMC) Following Vaccination.
The CMI responses were determined by intracellular staining/Fluorescence-Activated Cell Sorting(ICS/FACS) after in-vitro restimulation of PBMC with vaccine antigens on day 0 and day 50.
Day 1, Day 50
Number of Subjects Reporting Unsolicited Adverse Events After Receiving Two Doses of aTIV and TIV
The number of subjects reporting unsolicited AEs between Day 1 and the study termination i.e., Day 50, after receiving two doses of aTIV and TIV. Data are reported based on the Safety Set.
Day 1 to Day 50 post vaccination
Secondary Outcomes (3)
Percentage of Subjects Achieving Seroconversion or Significant Increase in HI Titer
