ackground: The success of policies to eradicate COVID-19 depends on the acceptance of vaccines among the population. This paper measures the influence on the intention to get vaccinated of three usual variables in studies on consumer behavior: the perception of the efficiency and risk of the vaccine and the social influence.
Methods: It was used a survey of 600 residents in Spain that was answered during September 2020 has been used. That survey was conveniently stratified by age and monthly income. The impact of the explanatory variables on the intention to use the vaccine was measured with generalized linear models: logistic regression and truncated negative binomial regression. Contro variables were gender, age and monthly income.
Results: We have observed a positive (negative) influence of the variables efficacy perception and social influence (perception of risk), i.e. a ratio of rate use above (below) 1 that is statistically significant (p<0.01 in the case of the first two variables and p<0.05 in the third). Their importance follows the order described above. Neither gender nor age were significant in the intention to get vaccinated, but the income level was. We identified that at the highest income levels there was a greater propensity to reject the vaccine (p<0.1).
Conclusions: The results may be useful to guide the information policy that health authorities should carry out in order to induce the population to use the SARS-CoV-2 vaccine.
