vApp

The virus type of VAPP was mainly type ⅲ, next the type ⅱ .

病毒型别主要为Ⅲ型，其次为Ⅱ型。

VAPP mostly occurred in children 1 year old after one dose of OPV vaccine .

主要发生在1岁儿童，且多为首次服苗后。

AFP surveillance and VAPP cases investigation should be strengthened to keep polio-free state in Fujian .

Objective To explore the situation of vaccine associated paralytic poliomyelitis ( VAPP ) in Shandong province .

目的了解山东省脊髓灰质炎（脊灰）疫苗相关病例（VAPP）的发病情况。

For realizing a polio-free country , VAPP is not to be neglected .

Methods Eighty one suspected VAPP cases reported by acute flaccid paralysis surveillance system were analyzed on the stage of polio-free from 1993 to 2000 in Shandong province .

方法对山东省1993～2000年期间通过急性弛缓性麻痹监测系统报告的81例疑似VAPP病例进行流行病学分析。

[ Objective ] To discuss the association of oral polio vaccine ( OPV ) and vaccine associated paralytic poliomyelitis ( VAPP ) .

[目的]为探讨口服脊髓灰质炎活疫苗（OPV）与脊髓灰质炎疫苗相关病例（VAPP）的关系。

During 1980 ~ 1998 , there were 9 cases of vaccine-associated paralytic poliomyelitis ( VAPP ) found in Shanghai .

上海市1980～1998年报告9例口服脊髓灰质炎疫苗相关病例（VAPP）。

The parallel algorithm is implemented on the Virtual Asynchronous Parallel Platform ( VAPP ) and the correctness is testified by the comparison of the simulation result of New England 10-generator 39-bus systems with a verified transient stability simulation program TSSP .

该算法在虚拟异步并行计算平台（VAPP）上得到了实现，并用新英格兰10机39节点系统算例和暂态稳定性仿真程序（TSSP）进行了验证。

In various regions of the world , VAPP incidence showed great difference . It was 1 / 2,500,000 ( number of vaccine handed out ) in America , 1 / 1,400,000 in England and 1.7 / 1,000,000,0.52 / 1,000,000 in Beijing and Shanghai of China respectively .

世界各地VAPP的发生率存在着明显的差异，美国1/250万（疫苗分发量），英国为1/140万，我国北京、上海市VAPP的发生率分别为17/100万和052/100万。

Methods We analyzed the epidemiological character of acute flaccid paralysis ( AFP ) cases with isolation of polio vaccine related virus strains and the occurrence of vaccine-associated paralytic poliomyelitis ( VAPP ) in the polio free phase in the past years .

方法分析无脊髓灰质炎阶段杭州市连续5年检出脊灰疫苗相关株病毒的急性弛缓性麻痹（AFP）病例的流行病学特征，以及疫苗相关麻痹型脊灰（VAPP）的发生情况。

After realizing the goal of polio-free , there shall be no circulation of indigenous wild poliovirus , but still requires a high coverage rate of oral polio vaccine ( OPV ), OPV may induce virus associated paralytic poliomyelitis ( VAPP ) in few vaccinees and their contacts .

实现无脊髓灰质炎（脊灰）目标后，已无本土脊灰野病毒的循环，但需维持口服脊灰疫苗（OPV）的高免疫覆盖率。
