Influenza infection is related to significant morbidity and mortality in children. The trivalent inactive vaccine (TIV) has been documented to have poor immunogenicity in children and the live attenuated influenza vaccine (ATIV) although proven to have more efficacy is unable to be administered to children under 2 years old. The MF59 adjuvanted influenza vaccine as proven efficacy on reducing the rates of laboratory confirmed influenza, including in children. The study aims to assess early gene transcriptional responses to priming and boosting with MF59-ATIV in children aged 13-24 months and adults aged 18 - 65 years, and to establish correlations with haemagglutination inhibition (HAI) titers. It will be an open label study with 90 healthy children allocated to 3 groups (groups 1, 2 and 3) and 30 healthy adults allocated to group 4.
