在这项研究中，我们表明，激励措施（狗项圈和主人腕带）是有效的，在大规模的狗狂犬病疫苗接种诊所，增加业主的参与，我们得出的结论是，家庭问卷调查和标记重新视线（横断面调查）的方法，估计接种后的覆盖率是准确的，当所有的狗，包括小狗，包括在内。在坦桑尼亚北方的中心点狂犬病疫苗接种诊所分发奖励措施，以量化其对业主参与的影响。在发放奖励的村庄，参与率有所提高，平均多34只狗接种疫苗。通过规模经济，这意味着每只狗的费用减少了0.47美元。这是一个价格阈值，在这个阈值之下，所使用的奖励措施的成本必须下降，才具有经济可行性。此外，还通过黄金标准的全村人口普查技术以及两种更便宜、更快的方法（随机家庭问卷和横断面调查）确定了十个村庄的疫苗接种覆盖率水平。还收集了成本数据。两个非金标准的方法被认为是准确的小狗时，包括在计算中，虽然样带调查和家庭问卷调查高估和低估的覆盖率。由于住户问卷调查可以收集更多的人口数据，而且其覆盖范围的估计较为保守，因此我们建议采用这种方法。尽管使用了激励措施，但平均疫苗接种覆盖率低于消除狂犬病的70%阈值。我们讨论了原因并提出了提高覆盖率的解决方案。鉴于最近的国际目标，以消除狂犬病，这项研究提供了宝贵的和及时的数据，以帮助改善大规模犬疫苗接种计划在非洲和其他地方。
In this study we show that incentives (dog collars and owner wristbands) are effective at increasing owner participation in mass dog rabies vaccination clinics and we conclude that household questionnaire surveys and the mark-re-sight (transect survey) method for estimating post-vaccination coverage are accurate when all dogs, including puppies, are included. Incentives were distributed during central-point rabies vaccination clinics in northern Tanzania to quantify their effect on owner participation. In villages where incentives were handed out participation increased, with an average of 34 more dogs being vaccinated. Through economies of scale, this represents a reduction in the cost-per-dog of $ 0.47. This represents the price-threshold under which the cost of the incentive used must fall to be economically viable. Additionally, vaccination coverage levels were determined in ten villages through the gold-standard village-wide census technique, as well as through two cheaper and quicker methods (randomized household questionnaire and the transect survey). Cost data were also collected. Both non-gold standard methods were found to be accurate when puppies were included in the calculations, although the transect survey and the household questionnaire survey over-and under-estimated the coverage respectively. Given that additional demographic data can be collected through the household questionnaire survey, and that its estimate of coverage is more conservative, we recommend this method. Despite the use of incentives the average vaccination coverage was below the 70% threshold for eliminating rabies. We discuss the reasons and suggest solutions to improve coverage. Given recent international targets to eliminate rabies, this study provides valuable and timely data to help improve mass dog vaccination programs in Africa and elsewhere.
