山羊痘疫苗免疫保护能力试验

Study on the efficacy of goat pox vaccine

为探索评价山羊痘的活疫苗对羊痘免疫保护效果,根据羊痘流行特点,对注射羊痘活疫苗30 d后的羊群（A组）和未进行免疫的健康羊群（B组）各随机抽选30只,与30只患有绵羊痘且具有典型症状的病羊混养,21 d后观察发病情况。结果显示,进行了疫苗免疫的实验组有28只羊未发病,有效保护率93.3%;未进行疫苗免疫的对照组只有13只羊未发病,有效保护率仅为43.3%。羊痘活疫苗免疫保护效果显著,通过疫苗免疫注射可起到有效保护作用。

This experiment was aimed to study the efficacy of goat pox vaccine. According to characteristics of goat pox pop,30 goats were randomly selected from goats inoculated with goat pox vaccine 30 days later（group A）,then mixed feeding with 30 health goats（group B） and 30 patients with goat pox. Typical symptoms of goat pox were observed after 21 days. The results showed that 28 goats in group A were unaffected by goat pox with an effective protection of 93.3%; while only 13 goats in group B were uninfected with an effective protection of 43.3%. Vaccine immunization can provide effective protection against goat pox infection.
