Introduction Elderly use to develop more complications after influenza and the 90% of deaths for influenza regards them. Indeed, they are among the major target of vaccination campaigns. The use of deprivation indices can help to identify subgroups with lower vaccine uptake. This work was aimed to analyze vaccination coverage of elderly living in Genoa using a local Index of Socio-Economic and Health Deprivation (SEHDI) in order to identify subgroups of population needing specific actions to improve vaccination coverage. Methods The target population was the population aged ≥65 years living in Genoa in the 2009-2013 period. Information about vaccination coverage derived from general practitioners. A combination of linear regression, factor analysis and cluster analysis was used to build the SEHDI at Census Tract (CT) level, deriving data from the 2011 Italian census. Results In Genoa, in 2011, people aged ≥65 years represented the 27.7% of the population. The majority of elderly belonged to medium (45.3%) and medium-high (32%) deprivation groups, while the percentages in the extreme tails were low (3.6% high deprived; 1.3% low deprived).
