[Study on factors affecting vaccination effect of poliomyelitis vaccine].
We carried out this 1:2 matched case-control study in some counties and townships in Guangxi, Henan and Jiangsu provinces from June to October in 1992 to find the risk factors of poliomyelitis incidence among fully vaccinated children. Then we processed the collected data with individual and multiple condition logistic regression analysis and found the risk factors of poliomyelitis incidence among fully vaccinated children included two kinds, the community factors and the individual factors. The community factors which related to the cold chain and health services. They are the special risk factors for fully vaccinated children. The individual factors are the common risk factors for both fully vaccinated and unvaccinated children. In addition, children received five or more doses of TOPV was a favorable factor against poliomyelitis. It was showed that we must improve vaccination quality while rising TOPV coverage continually.
