Willingness to receive COVID-19 vaccine booster doses for adults and their children in Vietnam

ABSTRACT

This study describes the willingness of receiving the COVID-19 booster doses for adults and their children 12–17 years old, and its related factors in Vietnam. A cross-sectional study was conducted through a national online survey from November 17 to November 24, 2021 using Google Form. Study respondents were Vietnamese citizens who were ≥18 years old and currently living in Vietnam. A total of 900 complete responses were analyzed and of those 93.77% were willingness to receive the booster dose. Participants with a university degree or higher were 8.16 times higher in willingness than those with primary school (p = .017). Those who received the first or the second dose of the COVID-19 vaccine were 5.85 (p = .001) and 5.65 (p < 0.001) times higher in willingness to receive booster doses, respectively. About the willingness to receive the COVID-19 vaccine for children 12–17 years, 89.2% of the participants were willing to have their children get the vaccine. Participants who had the first or the second dose of the COVID-19 vaccine had a 4.15 (p = .001) and 3.91 (p < 0.001) times higher willingness, respectively. Thus, the rate of willingness to receive the booster doses and the COVID-19 vaccine to children were excellent in this study. Both the education level and COVID-19 vaccination history were two positively associated factors.
