title: The sustainability of influenza vaccination programs: considerations and perspectives from Italy.
abstract: Influenza constitutes an annually recurring threat to society, from both the clinical and economic points of view. The impact of influenza is often underestimated, especially among frail elderly people, who are at increased risk of serious complications, including hospitalization and death. In Italy, around 10 million individuals aged 65 years and older are at risk of contracting influenza, and it can be estimated that the lack of a vaccination strategy would lead to more than 2 million cases and about 30,000 deaths. However, adherence to routinely recommended adult immunizations remains suboptimal despite the availability of safe and effective vaccines. Indeed, a monitoring program from the National Institute of Health in Italy has shown that influenza vaccination coverage in the elderly dropped to 49% in the 2014-2015 season, which is far below the maximum values (68%) recorded in the 2005-2006 season. The current situation in Italy imposes a need for greater sustainability in order to face the challenges related to the changing epidemiological situation, demographic transition and social transformations. Our review sums up the key elements of influenza vaccine sustainability and makes suggestions for improving the organizational structure of the present initiatives.
