[Training on vaccination for health care professionals].

Vaccinations in Italy show a downward trend since 2013 due to an evergrowing mistrust of the population with regard to vaccination that has resulted in lesser adherence to vaccination programs. The main cause of the reduction is due to a tendency observed in recent years, even at the international level, known as 'vaccine hesitancy'. A growing number of studies on vaccine hesitancy show that causes vary by country, population, vaccine, and context influences, but in all cases emerges the importance of health care professionals in patients decision about vaccine. The new Piano Nazionale della Prevenzione Vaccinale 2017-2019 (PNPV - Italian National Plan on Vaccine Prevention) underlines the need to invest for healthcare professionals in technical and scientific training not only about vaccination and vaccination strategies, but also on communication skills. Training interventions are also considered important for achieving another PNPV goal that is to "support, at all levels, the sense of responsibility of healthcare workers […..].". The training of health care staff is therefore recognized as a key aspect for the consolidation of national vaccination policies. It is intended to improve and standardize SSN's performance, skills and quality and to provide the essential tools to be able to respond adequately the growing demand for correct and exhaustive information from patients. Therefore, it is important to invest in strategies to improve technical, scientific and communication knowledges on vaccinations, adapting them to specific political, social and cultural contexts, in order to reinforce the sense of trust with citizens and to pursue the success of public health strategies to increase vaccine coverage.
