我省自1980年以来在重点地区进行流脑多糖体菌苗流行病学与血清流行病学效果观察。一次接种30μg 后保护效果可达4年之久,在预测的流行地区进行菌苗接种可降低发病率。1985年以来我省2800万儿童大面积现场观察流脑多糖体菌苗效果仍维持4年以上。验证了在菌群没有变迁的情况下,A 群流脑多糖体菌苗控制流脑是比较理想的,所制订的免疫方案是可行的。
Epidemiology and Seroepidemiology of Cerebrospinal Cerebrospinal Bacterial Vaccine in Our Province Since 1980 in Key Areas. After a single inoculation 30μg protective effect of up to 4 years, in the predicted areas of vaccination can reduce the incidence of vaccination. Since 1985, a large area of 28 million children in our province has observed the effect of the cerebrospiral polysaccharide vaccine for more than 4 years. The results showed that the control of meningococcal group A meningitidis was ideal when the bacterial population did not change, and the immunization protocol was feasible.
