Biological risk for healthcare workers: current Italian law and guidelines on vaccination strategies.

The assessment and management of biological risk has always been a primary goal toward which occupational medicine has focused its efforts, in particular in healthcare workplaces. Healthcare professionals represent a category of workers at high risk for infections, many of which are vaccine-preventable diseases. There are various reasons for vaccinating healthcare workers, including to prevent illness among them so as to reduce absenteeism, to ensure an effective health service to users and to reduce social costs. Recently, the issue of vaccinations has been the subject of many debates. Vaccination is not always appreciated by health operators, and the reasons for low vaccination coverage are several and heterogeneous. This paper focuses on current Italian law and vaccination policies, along with the international background, evaluating the effectiveness of current policies and the consequences on public health. Overall, preventing infectious diseases means reducing costs, cases and outbreaks, shows responsibility toward third parties, and improves general welfare.
