title: Parents' preferences and willingness-to-pay for human papilloma virus vaccines in Thailand.
abstract: 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.
