INTRODUCTION: As the protection from the COVID-19 vaccines diminishes over time, health authorities are currently considering how to maintain immunity by means of vaccine booster doses. In a recent survey, we investigated COVID-19 booster vaccine willingness among Danes, a population with a high acceptance of the initial round of COVID-19 vaccination.

METHODS: The data were derived from the sixth wave of the longitudinal COVID-19 Consequences Denmark Panel Survey 2020, which included questions on booster vaccine willingness. The data from the respondents were primarily analysed using descriptive statistics. The association between age, gender, level of education, region, type of received vaccine and booster vaccine willingness was analysed using multivariate logistic regression.

RESULTS: Among those reporting to be vaccinated against COVID-19 or that their vaccination was scheduled, a weighted total of 90% indicated that they were willing to receive the booster vaccine, if/once offered. The only characteristic associated with booster vaccine willingness at the set level of statistical significance (0.05) was age (increased willingness with age; adjusted odds ratio per year: 1.04, 95% confidence interval: 1.02-1.06).

CONCLUSIONS: The willingness to receive a booster dose of a COVID-19 vaccine is high among Danes. If health authorities decide to offer COVID-19 booster vaccines to the young, they may consider providing specific information targeted at this population to increase uptake.
