AbstractObjective: To determine the prevalence and factors associated with the intention to vaccinate against COVID-19 among older Brazilians. Methods: Cross sectional study based on telephone interviews among participants of the Brazilian Longitudinal Study of Aging (ELSI-Brazil) aged 60 years and over, conducted in 70 mucipalities on March, 2021. Results: Among the 4,364 participants (mean age=70.1 years), 91.8% had the intention to be vaccinated or had already been vaccinated, 2.5% did not have thisintention and 5.7% were undecided. Residents in the North and Southeast regions were more likely to be vaccinated, as were those with two or more chronic diseases. Those who learn about COVID-19 with friends/family/social media were more likely to be undecided about vaccination (odds ratio=3.15 – 95% confidence interval: 1.28;7.77). Conclusion: The results show one of the highest prevalence of intention to vaccinate against COVID-19 described in the literature to date.
