OBJECTIVE
To examine parents' preferences and willingness-to-pay (WTP) for HPV vaccines.
METHODS
A discrete choice experiment (DCE) was used. Parents with at least one daughter aged 9-13 years residing in Songkhla province were asked to choose one alternative from each DCE choice set describing HPV vaccines by four attributes, including cervical cancer risk reduction, genital warts risk reduction, common side effects, and cost. Multinomial logit model was used for data analyses.
RESULTS
Parents preferred higher risk reductions for cervical cancer and genital warts, and lower common side effects. They valued the quadrivalent and bivalent HPV vaccines at 21,189.9 and 10,479.9 Baht, respectively. Results also showed that mothers valued both vaccines more than fathers did.
CONCLUSIONS
Parents valued net benefits for both quadrivalent and bivalent HPV vaccines, but they were willing to pay for the quadrivalent vaccine more than for the bivalent vaccine.
目的
研究父母对人乳头瘤病毒（HPV）疫苗的偏好及支付意愿（WTP）。
方法
采用离散选择实验（DCE）。居住在宋卡府、家中至少有一名9至13岁女儿的父母被要求从每个DCE选择集中选择一个选项，这些选择集通过四个属性描述HPV疫苗，包括降低宫颈癌风险、降低尖锐湿疣风险、常见副作用和成本。采用多项logit模型进行数据分析。
结果
父母更倾向于更大程度地降低宫颈癌和尖锐湿疣风险，以及更低的常见副作用。他们对四价和二价HPV疫苗的估值分别为21,189.9泰铢和10,479.9泰铢。结果还表明，母亲对两种疫苗的估值均高于父亲。
结论
父母重视四价和二价HPV疫苗的净效益，但他们对四价疫苗的支付意愿高于二价疫苗。
