[Influenza vaccination in health care workers of a university hospital in Milan].

The study analyses the percentage of influenza vaccination in health care workers of a big university hospital in Milan during the season 2006/2007. The percentage of vaccinated subjects was 19.8%. The frequency of vaccination has also been assessed according to sex, age, job and school title. Observed data indicates that the number of vaccinated sanitary workers is far below the levels reached in other European countries and in the USA. Thus, in order to reach a higher adhesion to vaccination programs, sensitisation campaigns are necessary.
