Phylogenetic analysis of drifted A (H3N2) viruses circulating in the 2011–2012 winter. The phylogenetic tree represents the analysis of the HA1 nucleotide sequences of the HA gene of different influenza A(H3N2) viruses isolated in Italy in the Winter season 2011–2012. The four epidemic drifted A(H3N2) viruses isolated in Umbria (A/Perugia/06/12; A/Perugia/20/12; A/Perugia/44/12; A/Perugia/50/12) were used as antigens for studying heterologous antibody responses induced by IM-MF59 and ID influenza vaccine.
