After a massive epidemic of Bluetongue virus serotype 8 (BTV-8) among ruminants in 2006-2007 in the European Union (EU), the Netherlands started a voluntary emergency vaccination campaign in May 2008, subsidized by the EU. At the start of a new campaign in 2009, without subsidized vaccination, we investigated by mail survey the motives of farmers and hobby holders to vaccinate against BTV-8 in 2008 and 2009. Mean vaccine uptake in 2008 was: 73% in sheep, 71% in cattle, 43% in goat farms and 67% in hobby holdings. Top-5 motives pro-vaccination were: prevention of production loss; subsidized vaccination; recommendation by practitioner; welfare reasons; contribution to the eradication campaign. Top-5 motives against vaccination were: vaccination costs; absence of clinical BT-problems; presumed low infection risk; balance between vaccination costs and loss without vaccination; bad experience with earlier vaccination campaigns. Willingness to vaccinate was significantly lower in 2009: 42% in sheep, 58% in cattle, 19% in goat farms and 49% in hobby holdings. Measures to stimulate vaccination among those that did not want to vaccinate in 2009 were: subsidized vaccination; possibility to vaccinate their own animals; more information on efficacy/safety of vaccine and why animals had to be vaccinated again; availability of a BT vaccine combined with vaccine(s) against other diseases.
2006-2007 年，欧盟（EU）反刍动物中爆发了大规模的 8 型蓝舌病毒（BTV-8）疫情，随后荷兰于 2008 年 5 月启动了一项自愿的紧急疫苗接种运动，该运动由欧盟资助。在 2009 年新运动开始时，由于没有补贴接种，我们通过邮件调查研究了农民和业余爱好者在 2008 年和 2009 年接种 BTV-8 的动机。2008 年的平均疫苗接种率为：绵羊 73%、牛 71%、山羊场 43%和业余养殖场 67%。支持接种的前 5 个原因是：预防生产损失；补贴接种；从业者推荐；福利原因；为根除运动做出贡献。反对接种的前 5 个原因是：接种成本；无临床 BT 问题；假定感染风险低；接种成本与不接种的损失之间的平衡；对早期接种运动的不良经验。2009 年的接种意愿明显下降：绵羊 42%、牛 58%、山羊场 19%和业余养殖场 49%。对于那些在 2009 年不想接种疫苗的人，刺激接种的措施是：补贴接种；可以为自己的动物接种；提供更多关于疫苗效力/安全性以及为什么必须再次为动物接种的信息；提供一种与其他疾病疫苗结合使用的 BT 疫苗。
