The emergence of Covid-19 has affected all aspects of human life across the globe. Lockdowns everywhere are having dramatic social and economic consequences. No therapy has yet been approved, and vaccines are a priority potential tool to control the pandemic and its impacts. Multiple vaccines are in the last stage of the development process, but part of the population is not willing to get vaccinated for Covid-19. Several studies have examined the percentage of the population willing to get vaccinated, but few have analyzed the reasons for their decision. In this context, researching the factors influencing individuals’ intention to use a potential Covid-19 vaccine will be important to public health strategies. This paper analyzes these factors with an adapted Cognitive-Affective-Normative (CAN) model. Perceived vaccine efficacy is used as a cognitive variable, fear of the vaccine and fear of Covid-19 are used as affective variables, and social influence is used as the normative variable. The proposed model strongly explains the intention to use the Covid-19 vaccine (R2 = 0.81). The results show that vaccine efficacy will be the most important determinant of Covid-19 vaccine acceptance, followed by social influence. The findings can be very helpful for public health policies aimed at achieving widespread vaccination, a must for vaccine success.
