Background: The first dengue vaccine (DV) has been licensed in some countries, but an assessment of the public's acceptance of DV is widely lacking. This study aimed to explore and understand DV acceptance and its associated explanatory variables among healthy inhabitants of Aceh, Indonesia.

? 2019 Elsevier LtdTo help address the need for preventive measures against dengue fever, a leading cause of child mortality in the Philippines, vaccine trials are ongoing and a tetravalent vaccine (Dengvaxia?, Sanofi Pasteur) has been developed. It is hypothesized that while acceptability would be high among primary caregivers (i.e., parents/guardians), the willingness to have one's child immunized against dengue would be associated with socio-demographic variables, attitudes and knowledge regarding dengue and vaccination, and past experience with dengue. This study aimed to assess the aforementioned factors’ association with primary caregivers’ willingness to avail of a dengue vaccine for their 9 to 14-year-old children in an urban community in the Philippines. A cross-sectional study utilizing interviews was conducted to determine which factors were associated with willingness-to-avail assuming a free vaccine, and a case study utilizing a focus group discussion was employed to capture some underlying reasons for their willingness. Data were analyzed using multiple logistic regression and thematic analysis. Among the 202 study participants, 193 (95.54%) were willing to avail of the vaccine. There was a high probability of vaccine acceptance by primary caregivers (95.54%), with good attitude towards vaccination (≥12/15 points) [aOR 10.62, 90% CI (1.73–26.28)] and large household size (>5) [aOR 9.63, 90% CI (2.04–45.58)] being positively associated with willingness-to-avail, and good knowledge regarding dengue fever [aOR 0.10, 90% CI (0.03–0.74)] and older age (>44 years) [aOR 0.14, 90% CI (0.03–0.61)] being negatively associated. Crude analysis showed that household size, knowledge regarding dengue, and attitude towards vaccination were significantly associated with willingness. Multivariate analysis revealed that these factors and the primary caregiver's age were associated with willingness. Thematic analysis showed various perceptions regarding dengue and vaccination. Knowing these factors are associated with willingness-to-avail of the vaccine may help in understanding the audience of health promotion projects aimed at increasing immunization coverage.

The aim of this study was to study the relationships between economic status, knowledge, attitude and practice regarding dengue fever (DF), attitude towards vaccination against dengue virus infection, willingness to participate in a study on dengue, and acceptance of a dengue vaccine. Information on variables of interest was collected in questionnaire-assisted interviews during a community based cross-sectional survey conducted in Aceh, Indonesia. A proposed relationship model was tested using Confirmatory Factor Analysis (CFA), and an Exploratory Factor Analysis (EFA) was used to reconstruct an alternative relationship model among variables. Our proposed relationship model differed from the result of the EFA. The CFA indicated that knowledge and attitudes towards DF had the strongest relationship. We also found several direct relationships between sets of variables: a) economic status and knowledge on DF, b) economic status and practices regarding DF, c) knowledge and practices regarding DF, d) attitudes towards DF and dengue vaccine acceptance, as well as e) attitudes towards vaccination and dengue vaccine acceptance. There was no relationship between economic status and dengue vaccine acceptance. In conclusion, our model suggested that the most suitable factor to be targeted for improving dengue prevention was knowledge about DF. In addition, improving attitudes towards vaccination seemed to be the most appropriate effort to increase public acceptance of a dengue vaccine.

The introduction of new vaccines is accompanied by a variety of challenges. Among these, very important ones concern the questions whether the public is willing to accept and willing to purchase the vaccine. Here we discuss factors associated with these questions in the context of vaccines that are becoming available against dengue virus infection. We reviewed published studies available from PubMed and Embase, conducting a meta-analysis when possible and narrative review when the data did not qualify for meta-analysis. We found that attitude toward vaccination and socioeconomic level had significant associations with dengue vaccine acceptance. In addition, socioeconomic level, knowledge, attitude and practice regarding dengue fever, having personally experienced dengue fever and vaccine price were associated with willingness to pay for dengue vaccine. To improve acceptance and willingness to pay for dengue vaccine, well-designed introduction programs that address the associated factors in a context-specific manner are essential.
