[The supplementary effect of consulting vaccination in expanded program on immunization (EPI)]

This study was carried out in 420 of children aged 12-24 months in two counties of Gansu Province, China. The result showed that general consulting rate was 30.24% in county or township hospital. The average consulting time was 2.14. A formula was designed K = R x C (1-V) for detecting the effect of consulting vaccination in EPI. The maximum supplementary coefficients of initial immunization of outpatient children for the vaccines were as follows: BCG 0.3024, TOPV-3 0.0953, DPT-3 0.0929, MV 0.0643. And once immunization were BCG 0.3024, TOPV 0.2643, DPT 0.2381, MV 0.0643. The study also explores the supplementary effect of consulting vaccination in different vaccination times and immunization coverages.
