Abstract
Willingness to pay (WTP) for rotavirus vaccine was estimated using the contingent valuation method (CVM) employing the guardians of preschoolers as subjects. A survey to investigate WTP for rotavirus vaccine was conducted by distributing 1,366 questionnaires to the guardians of preschoolers, and 960 valid responses (70.3%) were obtained. The estimated WTP was \4,181, and the estimated WTPs that would ensure vaccination rates of 70% and 90% were \2,073 and \678, respectively. The estimated WTP based on household income was higher in the higher income group than in the lower income group. Our results suggest that minimization of the vaccination fee as far as possible would lead to a higher vaccination rate. In addition, the WTP estimated on the basis of household income suggests that the fee should be determined on this basis.
