Although predictors influencing nurses' vaccination practices have been identified to some extent regarding knowledge and risk perception [16] [17] [18] [19] [23] [24] [25] [26] [27] , further studies are needed to explore the influences on nurses' attitudes and practices regarding influenza vaccination and to identify the major influencing factors for their vaccination behaviours. This study aimed to examine the relationship between knowledge, risk perceptions, health beliefs towards seasonal influenza and vaccination and the vaccination behaviours of nurses.
