Active surveillance for safety monitoring of seasonal influenza vaccines in Italy 2015/2016 season

摘要

BackgroundSurveillance for adverse events following immunization is an important component of any national immunization programme because it is critical to assessing the safety of vaccines and to detecting potentially rare and severe adverse events and responding in a timely manner. We conducted an enhanced active surveillance aimed at assessing the safety of flu vaccines in the 2015–2016 season in Italy. The study was targeted to the population groups for which the seasonal vaccine is recommended in Italy.
