Abstract

Control of the COVID-19 pandemic largely depends on the effectiveness of the vaccination process. An understanding of the factors that underlie the willingness to accept vaccination contributes pivotal information to controlling the pandemic. We analyzed the association between the willingness to accept the available COVID-19 vaccines and vaccine determinants amidst the Chilean vaccination process. Individual-level survey data was collected from 744 nationally representative respondents and multivariate regression models were used to estimate the association between outcome and explanatory variables. We found that trust in COVID-19 vaccines, scientists, and medical professionals significantly increased the willingness to: accept the vaccines and booster doses, as well as annual vaccinations and the vaccination of children. Our results are critical to understanding the acceptance of COVID-19 vaccines in the context of a country with one of the world’s highest vaccination rates. We provide useful information for decision-making and policy design, in addition to establishing guidelines regarding how to effectively explain vaccination programs to citizens.

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Our findings must be considered in light of some limitations, which we address here. First, we captured different degrees of confidence through an ordinal scale with 4 values, while the variability of confidence may be higher. Second, although we approached different sociodemographic characteristics, it is necessary to consider additional aspects such as cultural, ethnic, rurality and income, among others. Third, given the context of physical distance, the application of the online survey mostly reached those who have constant access to the internet and technological resources, thus excluding people with lower accessibility or knowledge about the internet and technology. Although in these limitations we highlight aspects that must be considered and remedied in future studies, it is necessary to clarify that the present study is consistent and clearly underlined the conditions that propitiate the willingness to accept an annual vaccination, booster doses and the vaccination of children. In conclusion, our study reports a high intention of the Chilean population to receive a booster dose of the COVID-19 vaccine, annual vaccination and vaccination in children under 16 years of age. Vaccine acceptance is associated with trust in scientists, medical teams and in different media such as television and radio. Perception of risk is a factor that determines in adults the acceptances of vaccination or children vaccination or booster doses. This study provides the foundations on aspects...
