Introduction:
The Ministry of Health Circular “Prevention and Control of Influenza: Recommendations for the 2021-2022 Season” recommends influenza vaccination coverage for Health Care Workers of at least 75’, so as to ensure reduction of individual risk of illness, risk of transmission to individuals at high risk of complications/hospitalization, reduction of social costs related to morbidity and mortality and related absenteeism.

Materials and Methods:
Informative/training meetings were held at all the corporate Presidia of Asl Roma1 to raise awareness of influenza vaccination among health care workers, and vaccination was actively offered and on site.

Results:
During the 2020-2021 flu season, 18,753 health care workers were vaccinated in our Company out of a total of 50,798 vaccinated in the Lazio region, or 36.9’. Achieved coverage data were compared with those of the three ASLs in the urban area of metropolitan Rome, in which 34,996 workers were vaccinated. In the 2021-2022 flu season, there was a decline in the adherence of all target groups, including health workers: 10,586 vaccinated in our company out of 30,635 workers vaccinated in the region, or 34.56 percent. Following the same comparison with the three metropolitan Rome ASLs, the ratio was 53.3 percent.The 2022-2023 campaign is ongoing and the results will be presented at the conference

Conclusions:
It is widely documented that health worker vaccination has multiple values: it reduces the infectious risk of workers, protects patients from infection in care settings, and protects the operation of care services. Therefore, it is a priority to encourage the co-administration of influenza and anti-SARS-CoV-2 vaccination, to encourage vaccination promotion policies aimed at increasing awareness of the risks associated with the disease, and to promote on-site vaccination, training and information events of health care workers by validating the 5 C model (Confidence, Constraints, Complacency, Calculation and Collective responsibility).
