OBJECTIVE To understand the neutralized antibody level of the poliomyelitis among healthy in Jiangsu Province, and provide scientific evidence for ＇the immunization strategy. METHODS The healthy people were randomly enrolled from Lianyungang and Yangzhou City. The poliomyelitis antibody level were detected by cells neutralization test. SPSS 18.0 software was used for statistical analysis. RESULTS The neutralizing antibody positive rates for polio Ⅰ , Ⅱ and Ⅲ were 98.51%, 98.37%, 94.97%, the geometric mean antibody titers（GMT） were 1：186.21,1：125.89, 1：47.86 respectively in 736 serum specimens.There were no significant differences in antibody levels between different regions. But the GMT were significantly associated with age, which was decreased with the age increasing. CONCLUSION The poliomyelitis antibody positive rates and GMT are still maintaining a high-level in Jiangsu. The firm immune protective barrier had been built against poliomyelitis among healthy people.
