Data on influenza vaccination status among household contacts of asthmatic children are lacking. Our aim was to assess the influenza vaccination status of parents and caregivers of asthmatic children in the 2018-2019 season as well as to identify reasons for undervaccination. We performed a questionnaire-based survey in parents, caregivers and household contacts of 178 asthmatic children. Only the 50.6% of children were vaccinated, while in 79.8% of cases both parents were unvaccinated. More than 40% of them reported that they were unaware about the necessity of vaccination; approximately 30% stated that they were not properly advised, and the rest were concerned about influenza vaccine side effects and effectiveness. Factor analysis identified three groups: (a) influenza vaccine "believers" who were unaware that vaccination was necessary; (b) "deniers" who were less educated and with older children; (c) older and more educated vaccine "deniers". To improve influenza vaccine coverage among household contacts of asthmatic children, appropriate counseling and targeted interventions should be planned.
