Seasonal influenza is a major global health problem, responsible for thousands of deaths every year, including among children. As the global coronavirus 2019 (COVID-19) pandemic enters influenza epidemic season in the Northern hemisphere, vaccination against influenza is a public health goal.

We aimed to determine factors associated with parental willingness to vaccinate their children against influenza in 2021, especially those who did not vaccinate against influenza the prior year. We employed a global survey of caregivers accompanying their children 1-19 years old in 17 pediatric Emergency Departments (ED) in 6 countries between March 27 and June 30, 2020. The survey included demographic information, vaccination history and global attitudes to vaccination, as well as concern about COVID-19 illness of the child and caregiver during the ED visit.

Of 2422 surveys, 1314 (54.2%) caregivers stated they plan to vaccinate their child against influenza next year, an increase of 15.8% from the previous year. Of 1459 caregivers who did not vaccinate their children last year, 418 (28.6%) plan to do so next year. Factors predicting willingness to change attitude and vaccinate included child`s up-to-date vaccination status (aOR 2.03, 95% CI 1.29-3.32, P=.003); caregivers` influenza vaccine history (aOR 3.26, 95% CI 2.41-4.40, P< .010), and level of concern their child had COVID-19 (aOR 1.09, 95% CI 1.01-1.17, P=.022).

Changes in risk perception due to COVID-19 and previous vaccination may serve to influence decision-making among caregivers regarding influenza vaccination. To promote influenza vaccination among children, global public health programs can leverage this information.
