Immunisation against listeriosis in sheep using a live, attenuated vaccine was introduced in Norway in 1984. Since then 65,000 to 80,000 animals have been vaccinated annually. Information obtained by a questionnaire showed that the incidence of listeriosis decreased from approximately 4.0 per cent before the introduction of the vaccine to 1.5 per cent after vaccination started. The incidence of abortions was 0.7 per cent in vaccinated flocks compared to 1.1 per cent in unvaccinated flocks. There were a few adverse reactions in the vaccinated sheep.
1984年，挪威开始使用减毒活疫苗对绵羊进行李斯特菌病免疫接种。从那时起，每年有6.5万至8万只动物接种疫苗。通过问卷调查获得的信息显示，李斯特菌病的发病率从疫苗引入前的约4.0%降至疫苗接种开始后的1.5%。接种疫苗的羊群流产率为0.7%，未接种疫苗的羊群流产率为1.1%。接种疫苗的绵羊出现了一些不良反应。
