This study aims to measure the private demand for oral cholera vaccines in Hue, Vietnam, an area of relatively low endemicity of cholera, using the contingent valuation method.
Interviews were conducted with either the head of household or spouse in 800 randomly selected households with children less than 18 years old. Respondents were asked whether they would purchase an oral cholera vaccine with different levels of effectiveness and durations of effectiveness (both for themselves and for other household members) at a specified price.
The median respondent willingness to pay for 50% effective/3-year vaccine was estimated to be approximately $5, although 17% of the study sample would not pay for a cholera vaccine. The median economic benefit to a household of vaccinating all household members against cholera, as measured by its stated willingness to pay, was estimated to be $40 for a vaccine with these attributes.
The perceived private economic benefits of a cholera vaccine were high, but not evenly distributed across the population. A minority of the people in Hue place no value on receiving a cholera vaccine.
本研究旨在运用条件价值评估法，测算越南顺化地区霍乱疫苗的个人需求，该地区霍乱流行程度相对较低。
对800户随机选取的有18岁以下儿童的家庭进行访谈，访谈对象为户主或其配偶。询问受访者是否愿意以指定价格购买不同效力水平和有效期（针对自身及其他家庭成员）的口服霍乱疫苗。
估计受访者为效力50%/有效期3年的疫苗支付意愿中位数约为5美元，尽管17%的研究样本不愿为霍乱疫苗付费。按受访者表明的支付意愿测算，为所有家庭成员接种霍乱疫苗给家庭带来的经济收益中位数，对于具有上述属性的疫苗估计为40美元。
霍乱疫苗的个人经济收益可观，但在人群中的分布并不均匀。顺化地区少数人认为接种霍乱疫苗毫无价值。
