Abstract

Background: Vaccine hesitancy is increasing. We assessed attitudes toward influenza and COVID-19 vaccines and the relation between hesitancy to influenza vaccine and hesitancy towards COVID-19 vaccines.

Methods: A structured questionnaire administered during September 2020 to a representative sample of the Jewish Israeli population assessed attitudes and acceptance of influenza and COVID-19 vaccines. Factors for vaccine hesitancy were determined using logistic regression. Questionnaires were administered prior to the release of clinical data regarding efficacy and safety of COVID-19 vaccines and prior to vaccine rollout.

Results: We approached 10,625 people, of these 2,080 responded (19%), and 2,024 completed the questionnaire (97.3%), 64.9% aged 15-64 years and 35.1% aged ≥65 years. 37% had co-morbidities. 43.5% experienced financial deterioration due to the pandemic. 65.9% received influenza vaccine ≥1 time in the past. Influenza vaccination rates were higher in the elderly (81.8%). Reasons for influenza vaccine hesitancy were opinions that the vaccine is ineffective (27.1%), and fear of side effects (29.3%). 8.2% of people aged 16-64 and 13.8% of people aged≥65 refused to be vaccinated at least once over the course of one's lifetime. Percent of responders willing to receive a COVID-19 vaccine were higher than percent of responders willing to receive the influenza vaccine both in people aged 16-64 years (942 (72.3%) vs. 38.4%, respectively) and in people 65 years and older (84.0% vs. 76.8%, respectively). Hesitancy towards COVID-19 vaccine was associated with hesitancy towards other vaccines. Only 26.8% would participate in a COVID-19 vaccine trial.

Conclusions: Willingness to receive COVID-19 vaccine was higher than willingness to receive influenza vaccine. The results point to areas of fear from influenza vaccines side effects and lack of knowledge regarding influenza vaccines effectiveness that can be addressed to increase acceptance. Hesitancy towards other vaccines was associated with hesitancy towards COVID-19 vaccination.
