Objective: Protecting health care units from influenza epidemics has a double purpose: to decrease the mortality rate of patients at risk and to reduce work-leave in medical staff. An annual vaccination appears to be the most effective prevention against influenza. In France however the vaccinal coverage of health workers does not exceed 15%.
Method: In the 2003-2004 winter, the department of occupational health and the nosocomial disease committee of the Clermont-Ferrand Teaching Hospital initiated an active vaccination campaign. Three joint actions were carried out: date and place of vaccination sessions were individually addressed to every healthcare worker, meetings on prevention of influenza were held, as well as vaccination sessions on the work place in exposed units.
Results: Significant results were noted: vaccination rate increased 2.6 fold compared to the previous year (4.8 to 12.6%) and a vaccinal coverage rate of 29% in the exposed units.
Comments: The results even if far from national objectives encourage the pursuit of the campaigns promoting information and vaccination on the work place. The high frequency of reported postinjection adverse effects (1 out of 3) should be taken into account in future information campaign.
