Introduction:
The Ministry of Health Circular “Prevention and control of influenza: recommendations for the 2022-2023 season” identifies diabetics as being at higher risk of contracting invasive infectious diseases and developing serious complications.

Materials and Methods:
During the 2020-2021 flu season, influenza vaccination was actively offered to diabetic individuals aged 18-64 years. GPs and pediatricians were invited to actively call their diabetic patients. In the 2021-2022 flu vaccination campaign, mass mailing of letters via postal service was carried out to the 17,121 diabetic patients identified by the Lazio Region to promote their immunization. Finally, a comparison was made with what was done in the three metropolitan Local Health Authorities (ASL Roma 1, 2 and 3. The 2022-2023 immunization campaign is still ongoing and the results will be presented at the conference

Results:
During the 2020-2021 influenza season, 3,624 subjects were vaccinated by GPs and vaccination centers. In the 2021-2022 CVA, despite the general decline in adherence in all target categories, there was an increase in the absolute number of vaccinated diabetics with 4,437 subjects. This figure corresponds to 15.18% of what was achieved in the Lazio Region, but when compared with what was achieved in the Roman ASLs (1, 2, and 3), the figure recorded in Asl Roma 1 corresponds to 34.44%, in line with the residence data.

Conclusions:
In the light of the results achieved, we can affirm that the strategy of active calling of the target population, based on a principle of proximity, has proved successful and makes the need to create synergies with the territory to reach capillarly the immunizable subjects more and more evident.
