“…In this study, we found that women with lower levels of education had high rate of willingness to vaccinate, but this association was not statistically significant when being adjusted in regression model. Previous studies in China were in line with us when it was found that education was negatively correlated with the need of HBV vaccine and willingness to pay for it [16, 22]. The reason of this phenomenon is unclear.…”

Background. Hepatitis B virus (HBV) vaccine is a critical approach to prevent HBV transmission from mother to child. However, despite high HBV prevalence, evidence about the preference of women of productive age for HBV vaccine in Vietnam was constrained. This study aims to explore the preference and willingness to pay (WTP) for the HBV vaccine in Vietnamese women in productive age. Methods. A cross-sectional study was conducted in Hanoi in April 2016. A structured questionnaire was used to collect information about respondents’ socioeconomic status and knowledge about HBV vaccination. A contingent valuation approach was employed to measure the WTP for the HBV vaccine. Logistic and interval regressions were used to determine the associated factors. Results. Among 807 women, 80.8% were willing to have the vaccine injected which had the average price of 108,600 VND (95% CI, 97,580 VND–119,570 VND). Participants not suffering any diseases during pregnancy were more likely to be willing to pay for the HBV vaccine (OR = 3.41, 95% CI = 1.73–6.70). Not having the antenatal examination at central hospitals and working as farmers/workers were positively correlated with willingness to pay for this vaccine, while the number of children of respondents had a negative correlation with WTP. Conclusions. Our sampled women expressed a high willingness to pay for the vaccine. The price people were willing to pay for the vaccine, however, is equal to half of the actual price. These findings implied needs for better targeted public education interventions about HBV and the involvement of local medical staffs and the media in providing information. Efforts to reduce the price of the vaccine should also be warranted for scaling-up the coverage of this vaccine.

“…Logistic regression was used to assess the association between the outcome variable (vaccine uptake) and the independent variables (sociodemographics, knowledge, and risk perception regarding hepatitis B infection). First, all independent variables that had an association with the outcome variable based on previous studies [ 12 , 15 , 23 , 24 , 25 , 26 , 27 , 28 ] were included into a univariable logistic regression model, and crude odds ratios (COR) were obtained (model 1, Table 1 ). Subsequently, a multivariable logistic regression was applied to calculate mutually adjusted odds ratios (AOR) (model 2, Table 1 ).…”

To reach the goals of the Global Hepatitis Elimination 2030 program, Indonesia is now preparing a new regulation for hepatitis B vaccinations for adult population. This study aimed to determine the factors influencing vaccine uptake for hepatitis B in the adult population, and identify barriers to, and facilitators of, hepatitis B vaccination programmes. An explanatory sequential mixed methods design was implemented in this study. We conducted a survey involving 893 participants in the general population followed by 14 in-depth interviews with health providers. The survey found that only 15% (95% confidence interval 13–18%) of participants received at least one dose of the hepatitis B vaccine. Factors associated with vaccine uptake were, living in Yogyakarta compared to living in Aceh, having secondary and higher education compared to primary education, working as a health worker compared to working in other sectors, and having health insurance that covered hepatitis B vaccination compared to not having such health insurance. Our qualitative study also identified several barriers to the adult hepatitis B vaccination programme in Indonesia such as the high cost of vaccination, lack of vaccine availability in certain areas, limited human resources to implement the hepatitis B vaccination programme, and the ineffective dissemination of hepatitis B vaccination. This study highlights that accessibility and affordability of vaccinations are important determinants of vaccination uptake that should be taken into account when planning vaccination campaigns.

“…Previous studies have shown that the intention to receive the HBV vaccine is affected by individual's knowledge of HBV and the HB vaccine [11 12]. Research showed that migrant workers have poorer cognition of HBV and the HB vaccine, and a higher HBV prevalence rate, than permanent workers due to their poorer education and health awareness levels, living in groups and lower accessibility to health care [13][14][15][16]. Previous Chinese studies have also identified an individual's knowledge and cognition of HB and the HB vaccine as key factors explaining HB vaccination behavior, but these studies only employed partial measures of HBV cognition [17][18][19].…”

Background: Migrant workers are a susceptible population to the hepatitis B virus and a vulnerablespot in China’s immunization procedures. There is no free HB immunization program for migrant workers in China, so understanding migrant workers’ motivation to receive the hepatitis B vaccine is the first step in designing effect immunization policies.Method: A cross-sectional study was carried out in three migrant-dense industries in Tianjin, China. Our sample consisted of 406 migrant workers, 133 from the retail industry, 119 from the manufacturing industry, and 154 from the service industry. Protection motivation theory (PMT) factors were produced by principal component factor analysis. Socio-demographic variables, migration-industry variablesand PMT factors were estimated in a step-by-step binary logistic regression model to explore migrant workers intention to vaccinate.Results: The nested binary logistic regression model results suggested that the severity factor, self-efficacy factor and response cost factor from the PMT constructs were the three statistically significant factors (p<0.05) that affect the migrant workers vaccination intention. The severity factor and self-efficacy factor to HB vaccination were positively related to HB vaccination intention (OR=1.500, OR=1.631) while the response cost was negatively related to motivation to take HB vaccine (OR=0.626). The socio-demographic variables showed that younger, married and good self-rated health status participants were statistically associated with the intention of taking the HB vaccine. Sex, education level and income group were not significantly associated with vaccination intentions. The migration-industry variables show that migrant location had astrong effect on migrant workers’ vaccination intention.Conclusions: Applying integrated PMT constructs to the vaccination intention of Tianjin’s migrant population provide new insights into migrant workers’ intention to the HB vaccinate. Our findings suggest specific recommendations on health education and immunization management policies for migrant workers.
