Abstract

In this research, due to the importance of the infectious disease of influenza, the willingness to pay for the use of the influenza vaccine and the factors affecting it were investigated. The method used to calculate the willingness to pay is the contingent valuation survey based on the use of the  One-One Half Bounded(OOHB) Dichotomous Choice method. In this method, first, by using a pre-test questionnaire, the bid amounts were estimated using Cooper's method (DWEABS). Through the Mitchell and Carson formula, the sample size of 357 people was determined for the whole country. In the following, based on the log-normal distribution and the maximum likelihood method (MLE), the median and mean willingness to pay for the use of influenza vaccine were estimated to be 10800000 and 12300000 IRR, respectively. The results of the research showed that getting the influenza vaccine before, the importance of health issues, income, education, and disease background are the influencing variables on willingness to pay for the influenza vaccine
