Healthcare professionals' beliefs regarding influenza vaccination: What has COVID-19 changed?

Influenza poses a potential public health threat among healthcare professionals since an infected healthcare professional can spread the virus to patients at higher risk as well as his/her own family members and colleagues. Annual influenza vaccination is the most effective way to protect HCPs.

This study was conducted to determine whether demand for and beliefs about influenza vaccination have changed among healthcare professionals in the COVID-19 era and the factors that might have influenced them in the early phase of the pandemic when COVID-19 vaccines were eagerly awaited.

This observational descriptive study was conducted between November 16, and December 15, 2020. A total of 317 healthcare professionals completed an online survey. Bivariate analysis and binary logistic regression analysis were performed.

Nineteen (6.0%) healthcare professionals were regularly vaccinated against influenza every year, and 199 (62.8%) had never been vaccinated. During the 2019-2020 season, 30 (9.5%) participants had been vaccinated and the proportion desiring to be vaccinated against influenza during the 2020-2021 season was 49.8% (n = 158). The results revealed that those with chronic diseases, those who believed they had adequate information about influenza vaccination and those who believed healthcare professionals should be vaccinated against influenza regularly every year, respectively, had 3.5 times, 4.7 times, and 11 times higher vaccination rates.

Although the proportion of healthcare professionals with the intention to be vaccinated for influenza increased with the COVID-19 pandemic, it is still not high enough. Influenza vaccination rates should be promoted by in-service training programs.
