SARS-CoV2 vaccination adverse events trend in Italy. A retrospective interpretation of the last year (december 2020-eptember 2021)

At the end of 2020, a vaccination campaign against COVID-19 was launched. In 2021, legal obligations for health workers, as well as specific regulations for all workers, were introduced. The global SARS-CoV-2 pandemic was followed by epochal changes in life, school, and work habits in Italy. Therefore, the pharmacovigilance work currently being conducted in Italy by the AIFA concerning the recording and analysing of adverse reactions related to the use of vaccines has proved to be very important. The latest report, including a period of 10 months from December 2020 to September 2021, has allowed us to combine the results received so far, and to compare the safety of all vaccines currently available in Italy. The results of this analysis are highly encouraging and reveal the statistical reliability of the safety of the COVID-19 vaccines currently used in Italy. The dissemination of these findings could increase the public’s awareness of vaccines and their ability to make free and informed choices concerning vaccination. The potential increase in the Italian population’s adherence to the vaccination campaign could ultimately be a decisive factor in achieving herd immunity and the final resolution of the pandemic.
