Association between health care workers' knowledge of influenza vaccine and vaccine uptake.

Immunization is the most effective measure available to prevent influenza and its complications, and health care workers (HCWs) play a pivotal role. We conducted a cross-sectional survey study to determine HCWs knowledge and opinions regarding influenza vaccine and its acceptance at our institution. The most important reason for vaccine uptake was because it required formal declination (33%); physicians were more likely to be vaccinated because of patient care, whereas nurses were more likely to be vaccinated because it required formal declination.
