从重要意义上来看，VDPV带来的微小风险与口服脊髓灰质炎疫苗产生的巨大公共卫生相关益处相比黯然失色。

Increasing the rate of OPV immunization is an effective measure to protect children from wild poliomyelitis virus and vaccine variants.

提高OPV接种率是保护儿童免受脊灰野病毒、疫苗变异株病毒侵袭的有效措施。

The range of estimated fortified rate of OPV was from 66.90% to 90.25% between 1993 and 2003. The average incidence rate of measles was 24.01/ lakh, children aged under 3 years accounted for 30.13%, 61.12% measles cases without history of vaccination.

1993～2003年OPV强化免疫估算接种率为66.90%～90.25%；1995～2003年麻疹年平均发病率为24.01/10万，3岁发病占30.13%，61.12%的麻疹病例无免疫史。
