Abstract: (66 Views)
Introduction: Given the potential spread of infectious diseases, including monkeypox, conducting studies to ensure the effective implementation of prevention programs is crucial. In this context, understanding the public’s willingness to pay (WTP) for the monkeypox vaccine is a critical priority for public health management. This study estimated WTP for monkeypox vaccine in Iran.
Methods: WTP for the monkeypox vaccine was estimated using the one-and-one-half-bounded (OOHB) dichotomous choice contingent valuation method. The factors influencing willingness to pay were analyzed using an econometric model based on the maximum likelihood estimation method. Data were collected through an online questionnaire administered nationwide in Iran during the summer of 2023. The bid amounts were determined using the Cooper approach (DWEABS) , and the sample size was set at 356 individuals based on the Mitchell and Carson method. Data werer analzed using the R in RStudio software.
Results: The median and mean willingness to pay for the monkeypox vaccine were estimated at 91,000 and 136,000 Iranian Tomans, respectively. In addition, the results indicated that age, importance to health issues, income, education, and disease background significantly influenced the willingness to pay for the monkeypox vaccine.
Conclusion: The estimated willingness to pay for the monkeypox vaccine was 136,000 Tomans (approximately 2.5 USD). Offering subsidies, paticullary with consideration of income diaparities, can encourage a larger segment of the population to receive the monkeypox vaccine.
