Knowledge, acceptance and willingness to pay for Dengue vaccine in Yogyakarta and Jakarta

摘要

abstract_textpDespite the fact that Dengue Hemorrhagic Fever (DHF) is one of diseases with the highest incidence rate in Indonesia, its prevention strategies remain ineffective. One of the most cost-effective strategies to prevent DHF is through vaccination. This study aimed to investigate correlations between the knowledge of DHF, the behavior of DHF prevention and the knowledge of vaccine with the acceptance of dengue vaccine and willingness-to-pay (WTP) of dengue vaccine in Yogyakarta and Jakarta, Indonesia. A cross-sectional study was conducted by collecting data from people visiting primary healthcare centers (PHCs) through a valid and reliable questionnaire. A purposive sampling was applied, which resulted in 838 respondents among PHCs in Yogyakarta (two selected districts: Bantul and Kulon Progo) and Jakarta (two selected districts: West Jakarta and Central Jakarta). The result showed that the percentage of respondents who had good knowledge of vaccine was estimated to be 67-77 in all districts. The percentage of respondent who had good acceptance of vaccine was estimated to be 68-81. WTP of dengue vaccine among respondents was estimated to be IDR 10,000-50,000. The result showed that the knowledge of DHF was significantly correlated (p0.05) with the acceptance of dengue vaccine in districts of West Jakarta, Bantul and Kulon Progo. In particular, the behavior of DHF prevention and the knowledge of dengue vaccine were significantly correlated (p0.05) with the acceptance of dengue vaccine in all districts. Additionally, the knowledge and acceptance of vaccine were significantly correlated (p0.05) with WTP in West Jakarta only. It can be concluded that correlation among variables in all districts are not the same. Hence, specific approach is required to be applied in each district./p/abstract_text
