疫苗预防疾病的效果取决于疫苗本身的效价及其合理使用,以产生免疫应答。目前已有办法检测疫苗效价和宿主的应答情况。为保证疫苗的质量,对疫苗生产及其经冷链运转后进行效价测定是一种重要的监测手段,疫苗在运送到各地后,要从现场取回样品作检测,以保证疫苗效价没有损失。血清学研究可用于确定疫苗的免疫效果。血清阳转率可用于估量宿主免疫应答的产生, The effectiveness of a vaccine against disease depends on the potency of the vaccine itself and its reasonable use to produce an immune response. There are ways to test vaccine potency and host response. In order to ensure the quality of the vaccine, it is an important monitoring measure for the production of the vaccine and its potency determination after the cold-chain operation. After the vaccine is transported to other places, the samples should be retrieved from the field for testing to ensure that the vaccine potency is not loss. Serological studies can be used to determine the vaccine’s immune response. Seroconversion rates can be used to assess the production of a host immune response,
