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.
Interventions
2 x 0.25 ml doses administered intramuscularly in the deltoid muscle of (preferably) the non dominant arm
