Individuals' willingness to pay for HIV vaccines in Iran: Contingent valuation method.

BACKGROUND AND AIMS: This study aims to assess individuals' willingness to pay (WTP) for a human immunodeficiency virus (HIV) vaccine in Iran, focusing on key determinants influencing vaccine acceptance. Utilizing the contingent valuation method (CVM), we aim to provide insights into the economic and socio-cultural factors shaping WTP in Iran. METHODS: We conducted face-to-face surveys with 468 participants in Tehran province using purposive sampling. We analyzed demographic characteristics, perspectives on HIV/AIDS, and financial considerations alongside participants' WTP. Statistical analyses, including maximum likelihood estimation, identified factors influencing WTP. Mean WTP values were calculated to quantify the economic valuation of an HIV vaccine. RESULTS: Higher education and monthly income significantly correlated with increased WTP, while gender, age, marital status, and health insurance showed no substantial impact. The mean WTP was 12,590.83 to 12,599.63 thousand Rials in different models, both showing statistically significant WTP values. CONCLUSION: Higher education and income levels are key determinants of WTP for an HIV vaccine in Iran. These findings provide valuable insights for policymakers to enhance vaccine accessibility and acceptance in Iran.
