Model 1, Crude model.

Model 2, Adjusted for sociodemographic variables (sex, age, residence, education, work, parenthood, live with parents).

Model 3, Adjusted for sociodemographic variables and medical condition (chronic disease, allergy history, frequency of colds).

Model 4, Adjusted for sociodemographic variables, medical condition, knowledge about Vaccination and infected with COVID-19.

Model 5, Adjusted for sociodemographic variables, medical condition, knowledge about Vaccination, infected with COVID-19 and friends infected with COVID-19.
