全球消灭脊髓灰质炎 (脊灰 )活动取得了巨大进展 ,世界卫生组织 6个区中有两个区已宣布为无脊灰区。但在实现无脊灰目标后 ,将面临许多问题 :脊灰野病毒的输入 ,疫苗衍生脊灰病毒 (Vaccine derivedpoliovirus,VDPV)的流行 ,疫苗相关麻痹型脊灰病例的发生 ,以及免疫、监测、实验室脊灰野病毒封存与销毁等问题。针对这些问题应采取的措施主要是 :保持高水平的免疫接种率和高质量的急性弛缓性麻痹病例监测工作 ,开展VDPV的监测 ,做好实验室脊灰野病毒封存与销毁工作 ,可根据国家的财力调整更改疫苗品种的免疫策略。
Great strides have been made in the global eradication of poliomyelitis (polio), with two of WHO’s six districts declared as polio free. However, many problems will be faced after achieving the goal of polio-free status: the input of poliovirus, the epidemic of Vaccine derived poliovirus (VDPV), the incidence of vaccine-associated paralytic poliovirus cases, and immune, surveillance, and experimental Room gray wild virus storage and destruction and other issues. The main measures to be taken on these issues are to maintain a high level of immunization coverage and high-quality monitoring of cases of acute flaccid paralysis, to monitor VDPV, and to carry out the storage and destruction of laboratory poliovirus. According to the national Financial Adjustment Changes Vaccine Variety Immunization Strategy.
