The aim of this study is to conduct a systematic review in order to estimate the pooled prevalence of influenza vaccinations among nurses and ancillary workers in Italy and analyze the enhancing and hindering factors. Results: The review was performed using 15 articles, 6 containing the prevalence of vaccination for nurses and ancillary workers, while the others qualitative analysis. In all the selected articles the score calculation has been performed by using a protocol for observational studies. The nurses and ancillary workers pooled proportion of influenza vaccination was respectively 13.47% (95% CI: 9.58-17.90%) and 12.52% (95% CI: 9.97-15.31%). Discussion: The Italian mean of influenza vaccination prevalence appear low if compared with other European countries, ranging from 15% to 29% in Countries such as UK, Germany, France. This situation of weakness should be seen as an opportunity to improve the vaccination rate for seasonal influenza significantly. This should be done by intervening on the category which affirms caring less. In fact, this category has a priority to receive vaccination, due to their numbers and closer contact to patients.
