  Purpose

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.

Official Title: 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

Primary Outcome Measures:
  • Cell mediated immune (CMI) responses as determined by the quality and quantity of the antigen-specific T- cells responses after in-vitro restimulation of peripheral blood mononuclear cells at day 0 and day 50 following vaccination.Safety and tolerability [ Time Frame: 50 Days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Seroprotection, GMRs and seroconversion rate at day 0 and day 50 after vaccination [ Time Frame: 50 days ] [ Designated as safety issue: No ]
