Knowledge, Preference, and Willingness to Pay for Hepatitis B Vaccination Services among Woman of Reproductive Age in Vietnam

Abstract

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.

Using Contingent Valuation Method to Estimate Adults’ Willingness to Pay for a Future Coronavirus 2019 Vaccination

“…Meanwhile, only one-tenth of the study population has sought information relating to the vaccine from community health workers or healthcare staff at hospitals. Our results were consistent with the earlier studies in Vietnam regarding the vaccination of dengue fever, 27 , 28 hepatitis B, 29 and human papillomavirus. 30 These research explored that different types of mass media consisting of social media, the internet, and television were main methods to provide information about Covid-19 vaccine to the Vietnamese general population.…”

Income Inequalities in Hepatitis B Vaccination and Willingness to Pay Among Women of Reproductive Age in Hanoi, Vietnam

“…Among those willing to pay, the mean maximum was US$10.30, over twice the amount found by a similar study in 2016 (108,600 VND, US$4.73). 13 When participants were asked how much they were willing to pay, differences between income levels emerged for maximum prices greater than US$4.50. We found that 50% of women from Q4 and Q5 were willing to pay a maximum price between US$9–US$18, whereas 50% of women from Q1 were willing to pay less than US$9.…”

“…A promising strategy that has been proposed to decrease rates of HBV infection transmission and improve disease control is vaccination of women of reproductive age (WRA). 13 During pregnancy, women are vaccinated to confer immunity to neonates, 14 given the risk of horizontal transmission in adulthood. However, there is a lack of randomized controlled trials on the efficacy of HBV vaccination for WRA to prevent maternal infection and consequently neonatal infection.…”

The impact of exposure to HPV related information and injunctive norms on young women's intentions to receive the HPV vaccine in China: A structural equation model based on KAP theory

“…Secondly, we also speculated that this result might be explained by the perceived cost to the individual, with studies demonstrating that the high price of vaccines was a major cause of vaccine hesitancy, and that even if people were better informed about vaccines, the perceived high cost in terms of time, price, and availability would deter their vaccination ( 73 ). However, at this stage, there are still few pilot cities in China where girls of appropriate age can receive the domestic bivalent HPV vaccine for free, and the age is basically limited to women under 18 years old, so most women still need to pay for the HPV vaccine themselves.…”
