Tetanus vaccine coverage in Vietnam has been declining in recent years due to a rapid population growth rate, shrinking budget, and inefficient resource mobilization strategy. This study examined the uptake, demand, and willingness to pay (WTP) for tetanus vaccines in Vietnamese women of reproductive age as well as determined associated factors and assessed the feasibility of the long-term tetanus vaccine resource mobilization scheme.
Cross-sectional data were obtained on 807 women of childbearing age in Hanoi, Vietnam in 2016. Tetanus vaccine uptake, demand, and willingness to pay were collected by using a structured questionnaire. Multivariable logistic and interval regression models were used to examine associated factors with vaccine uptake, demand, and WTP.
Of 807 participants, 42.4 and 64.8% had sufficient tetanus vaccination (i.e., received at least three doses of vaccine) and were willing to pay for tetanus vaccination. The mean amount of WTP for one dose of tetanus was US$ 7.3 (95% CI = 6.7-7.9). Having children or being aware that the tetanus vaccine was free-of-charge were negatively associated with WTP for tetanus vaccine. Having a high school education, living in a rural area, and not being aware of vaccine prices or being aware that vaccines were provided freely reduced the amount of WTP. WTP increased among women receiving information from friends and relatives.
Despite of exemption from the tetanus vaccination programs, this study indicated a low tetanus vaccination coverage and a moderate degree of WTP for tetanus vaccine among Vietnamese women of childbearing age. Target-specific educational and financial support interventions, along with efforts to reduce vaccination costs are critical to improving the vaccine uptake, demand, and WTP for tetanus immunization among women.
近年来，由于人口增长率迅速、预算缩减以及资源动员策略效率低下，越南的破伤风疫苗接种覆盖率一直在下降。本研究调查了越南育龄妇女对破伤风疫苗的接种、需求和支付意愿（WTP），确定了相关因素，并评估了长期破伤风疫苗资源动员计划的可行性。
2016 年在越南河内对 807 名育龄妇女进行了横断面数据收集。通过结构化问卷收集破伤风疫苗接种、需求和 WTP。使用多变量逻辑和区间回归模型来研究与疫苗接种、需求和 WTP 相关的因素。
在 807 名参与者中，42.4%和 64.8%有足够的破伤风疫苗接种（即，接种了至少三剂疫苗），并愿意为破伤风疫苗接种付费。每剂破伤风疫苗的平均 WTP 为 7.3 美元（95%CI=6.7-7.9）。有孩子或知道破伤风疫苗是免费的与破伤风疫苗的 WTP 呈负相关。接受过高中教育、居住在农村地区、不知道疫苗价格或知道疫苗是免费提供的，会降低 WTP。从朋友和亲戚那里获得信息的女性的 WTP 会增加。
尽管破伤风疫苗接种计划豁免，但本研究表明，越南育龄妇女的破伤风疫苗接种覆盖率较低，对破伤风疫苗的 WTP 程度中等。针对特定人群的教育和财政支持干预措施，以及降低疫苗接种成本的努力，对于提高妇女对破伤风免疫的疫苗接种、需求和 WTP 至关重要。
