传染性牛胸膜肺炎（CBPP）在撒哈拉以南非洲大部分地区是一种经济上重要的疾病。使用联合分析和有序probit回归模型来衡量农民对CBPP疫苗和疫苗属性的偏好。这涉及疫苗是否纳入一项指标、疫苗安全性、疫苗稳定性以及疫苗接种的频率、疫苗管理和疫苗接种的性质。在2006年10月至12月期间，对肯尼亚纳罗克地区的190个家庭进行了分析，采用结构化问卷、16个属性概况和5分李克特量表。通过双向位置交互模型揭示了影响属性评价的因素。研究还证明了属性的相对重要性（RI）和属性层次的补偿值。属性系数估计显示，农民更喜欢有指标、100%安全且由政府管理的疫苗（p < 0.0001）。对疫苗属性的偏好与预期一致。农民对稳定性、疫苗接种频率和疫苗接种性质的偏好不同（p > 0.05）。在疫苗中纳入一项指标是最重要的属性（RI = 43.6%），而价格是最不重要的（RI = 0.5%）。在考虑的22个家庭因素中，有15个影响属性估值。从未纳入到纳入指标、95-100%的安全性、2小时到大于2小时的稳定性、从强制接种到选择性接种的补偿值为正，而从每年接种到两年接种、从政府接种到私人接种的补偿值为负。该研究得出结论，纳罗克地区的农民对特定疫苗和疫苗接种属性有偏好。这些偏好受到各种家庭特征和疾病风险因素的制约。平均而言，农民需要得到补偿或说服他们接受一年两次的私人疫苗接种。在疫苗配制过程中需要考虑农民对疫苗属性水平的偏好，在设计疫苗交付时需要考虑农民对疫苗属性水平的偏好。(C) 2013 Elsevier B.V.版权所有
Contagious bovine pleuropneumonia (CBPP) is an economically important disease in most of sub-Saharan Africa. A conjoint analysis and ordered probit regression models were used to measure the preferences of farmers for CBPP vaccine and vaccination attributes. This was with regard to inclusion or not of an indicator in the vaccine, vaccine safety, vaccine stability as well as frequency of vaccination, vaccine administration and the nature of vaccination. The analysis was carried out in 190 households in Narok District of Kenya between October and December 2006 using structured questionnaires, 16 attribute profiles and a five-point Likert scale. The factors affecting attribute valuation were shown through a two-way location interaction model. The study also demonstrated the relative importance (RI) of attributes and the compensation value of attribute levels. The attribute coefficient estimates showed that farmers prefer a vaccine that has an indicator, is 100% safe and is administered by the government (p < 0.0001). The preferences for the vaccine attributes were consistent with expectations. Preferences for stability, frequency of vaccination and nature of vaccination differed amongst farmers (p > 0.05). While inclusion of an indicator in the vaccine was the most important attribute (RI = 43.6%), price was the least important (RI = 0.5%). Of the 22 household factors considered, 15 affected attribute valuation. The compensation values for a change from non inclusion to inclusion of an indicator, 95-100% safety, 2 h to greater than 2 h stability and from compulsory to elective vaccination were positive while those for a change from annual to biannual vaccination and from government to private administration were negative. The study concluded that the farmers in Narok District had preferences for specific vaccine and vaccination attributes. These preferences were conditioned by various household characteristics and disease risk factors. On average the farmers would need to be compensated or persuaded to accept biannual and private vaccination against CBPP. There is need for consideration of farmer preferences for vaccine attribute levels during vaccine formulations and farmer preferences for vaccination attribute levels when designing delivery of vaccines.
