•Insufficient vaccinal uptake in HCWs may impact influenza outbreaks in health care settings in France.•Vaccination coverage in HCWs is dependent on HCWs’ status, age, and practice.•Acceptance of mandatory influenza vaccination for HCWs is related to status, age and having received seasonal vaccination. Influenza is recognized as a public health threat. However, vaccine hesitancy and poor vaccine uptake have been seen in French healthcare workers (HCWs). As a result, authorities have considered implementing mandatory influenza vaccination for HCWs. This study aimed to describe factors associated with influenza vaccine adherence or non-adherence in French HCWs and to collect their perception about mandatory influenza vaccination. In February 2017, during the influenza season, a standardized questionnaire was sent electronically to the professional email addresses of French HCWs. Analyses were performed having collected 3000 responses. Between February 1 and 16, 2017, a 14-question survey was sent to HCWs professional email addresses. After a two week period had elaspsed, 3000 answers were collected for analysis. Overall, 45.7% of responders reported they had received influenza vaccination in 2016–2017, with statistical differences relating to professional status, age and practice. In addition, 92.2% reported caring for at-risk patients and 62.9% had a community-based practice. Finally, accepting mandatory influenza vaccination was statistically associated with higher age, a higher socio-professional category, and seasonal influenza vaccine uptake, but not with management of at-risk patients. Electronically submitted questionnaires are a rapid and easy tool that can be used to describe factors associated with influenza vaccine uptake in HCWs. In our study, differences in receiving influenza vaccination related to age, practice and professional categories, and provided an insight into potential adherence to mandatory influenza vaccination in HCWs. If repeated, these surveys may also monitor the evolution of vaccine uptake by professional categories.
