Healthcare Workers' Willingness to Receive Influenza Vaccination in the Context of the COVID-19 Pandemic: A Survey in Southern Italy.

This cross-sectional survey was designed to evaluate hospital healthcare workers' (HCWs) willingness to receive the influenza vaccination during the COVID-19 pandemic and to identify the related determinants, since it is plausible that the two epidemics will coexist in future winters. Overall, 68% out of 490 participants expressed their willingness to receive influenza vaccination in the 2020/21 season, with 95% of those ever and 45.8% of those never vaccinated in the previous six influenza seasons. Belief that influenza vaccine is useful in distinguishing influenza symptoms from those of COVID-19 and that the influenza vaccine is useful to prevent influenza in hospital settings, willingness to receive COVID-19 vaccination, having no concern about influenza vaccine side effects, concern about the possibility to transmit influenza to hospitalized patients, and influenza vaccination in previous years were all predictors of willingness to receive influenza vaccination. In the context of the COVID-19 pandemic, a relevant increase in the willingness to undergo influenza vaccination was reported. Therefore, interventions focused primarily on enabling factors are needed to promote the adherence to influenza vaccination in future seasons among HCWs.
