Vaccination of cattle against viral respiratory pathogens to minimize losses associated with bovine respiratory disease (BRD) is a common practice among producers and veterinarians. Three different calf populations in which BRD is most prevalent (recently weaned beef calves, preweaning beef calves, and young dairy calves) are the principal focus of morbidity and mortality prevention through vaccination; however, the evidence of vaccination efficacy is inconsistent in the literature. This review addresses the evidence of efficacy of vaccination in the prevention or reduction of naturally occurring and experimentally induced BRD in each calf group.
给牛接种病毒呼吸道病原体疫苗以尽量减少与牛呼吸道疾病 (BRD) 相关的损失是生产者和兽医的常见做法。最近断奶的肉牛犊、未断奶的肉牛犊和年轻的奶牛犊这三个 BRD 最常见的小牛群体是通过疫苗接种预防发病率和死亡率的主要关注点；然而，文献中疫苗效力的证据并不一致。本综述讨论了疫苗在预防或减少每个小牛群体中自然发生和实验诱导的 BRD 的功效证据。
