Nurses' vaccination against pandemic H1N1 influenza and their knowledge and other factors

► We surveyed 522 nurses of whom 33% had been vaccinated against H1N1. ► Vaccination was significantly higher among male (56.7%) compared to female (32.1%) nurses. ► There were significantly different vaccination rates among nurses working in different clinical specialties. ► Vaccinated nurses were significantly more likely to report recommending H1NI vaccination to patients. ► Lack of knowledge and risk perception predicted the nurses' vaccination behaviours.
