Key Points

This study aims to explore public preferences and willingness to pay for COVID-19 vaccine boosters in Singapore, considering sociodemographic and health-risk factors.
Conducted a discrete choice experiment survey among the general population in Singapore, recruited from an online panel in June 2022.
Used a 2-stage discrete choice design to present hypothetical scenarios regarding booster characteristics and risks.
Applied a mixed logit model for analyses to estimate willingness to pay and assess associations with sociodemographic factors.
Respondents preferred boosters with longer protection duration, willing to pay S$1.43 for each percentage-point increase in effectiveness and S$4.95 per additional month of protection.
Younger adults, women, non-Chinese individuals, and those with higher socioeconomic status were more likely to accept boosters.
Conversely, older adults, individuals with lower socioeconomic status, and those with prior COVID-19 infection were less likely to accept booster vaccination.
