提出了许多问题,以及在(鼻内)牛呼吸道疾病复杂疫苗接种的新时代面临的挑战。预计疫苗接种率会提高,由于它对牛健康的积极影响,减少抗菌药物的使用和经济因素。然而,农民和兽医对疫苗接种的参与往往受到限制的影响,导致疫苗接种障碍的发展,但也有机会克服这些。该报告的目的是就BRDC疫苗接种的最佳做法提供切实可行的建议和共识,解决兽医和农民面临的障碍。该报告结合了证据审查和专家意见,并讨论了不同的疫苗接种方法,例如鼻内和全身方案。作为讨论的结果,确定了BRDC疫苗接种的几个障碍,包括缺乏对疾病影响的知识或可见性,对一揽子抗生素使用的偏好超过疫苗接种,抵抗变化,需要可见的成功,不确定接种疫苗的最佳时间,以及在母体抗体存在下的不良反应和疫苗功效的担忧。虽然这些障碍似乎很大,它们为兽医部门提供了机会。的确,鼓励兽医使用所提出的论证,以及当地的案例研究和诊断测试,以强调疾病的影响,在进行小腿健康审计时,确保期望得到管理,以取得明显的成功。总的来说,这份共识文件旨在为兽医和农民提供切实可行的建议和支持,以克服障碍,提高牛的BRDC疫苗接种率.
Many questions are raised, and challenges faced in the new era of (intranasal) bovine respiratory disease complex vaccination. An increase in vaccination rate is expected, due to its positive impact on cattle health, reduction of antimicrobial use and economic factors. However, engagement of farmers and veterinarians with regard to vaccination is often affected by limitations, resulting in the development of barriers to vaccination, but also opportunities to overcome these. The objective of the report is to provide practical recommendations and a
consensus on best practises for BRDC vaccination, addressing barriers faced by veterinarians and farmers. The report combines an evidence review with expert opinions and includes discussions on different vaccination approaches, such as intranasal and
systemic protocols. As result of the discussions, several barriers to BRDC vaccination were identified, including a lack of knowledge or visibility of the disease\'s impact, the preference for blanket antibiotic use over vaccination, resistance to change, the need for visible success, uncertainty about the best time to vaccinate, and concerns about adverse reactions and vaccine efficacy in the presence of maternal antibodies. While these barriers seem substantial, they provide opportunities for the veterinary sector. Indeed, veterinarians are encouraged to use the argumentation presented, along with local case studies and diagnostic testing to highlight the impact of disease, while conducting calf health audits, ensuring expectations are managed to achieve visible success. Overall, this
consensus paper aims to provide practical recommendations and support for veterinarians and farmers to overcome barriers and increase BRDC vaccination rates in cattle.
