The analysis of the supervision for adverse event following immunization in Liwan district of Guangzhou in 2012

Objective To understand the supervising situation of AEFI in Liwan district of Guangzhou, analyze the potential reasons for AEFI, and provide evidence for enhancing the quality of vaccinum as well as improving the services of preventive inoculation. Methods Analyze AEFI cases within vaccination report in every clinic of Liwan district. Results The vacci- num which has been preventive inoculated includes 82 types, and 352 723 doses, among them 22 types are reported AEFI including 157 cases. The occurance of AEFI is 44.51/100 000, in which normal events occur 27.50/100 000 （61.78% ） , adverse events occur 15.88/100 000 （ 35.67% ） ,while adventitious events occur 11.34/100 000 （2.55% ）. Among 157 AEFI cases, children aged 0-1 year occupies 112 cases （ 71.34% ）, children aged 0-7 years occupies 156 cases （ 99.36% ）. Occurance rate of AEFI appears high in pneumococcal 7-valent conjugate vaccine, diphtheria pertussis tetanus vaccins and pneumococcal vaccine, polyvalent 23,being reporting that occurance for above types are 253.32/100 000,203.94/100 000 and 190.28/100 000 ,respectively. Conclusion It suggests that the spreadability and sensibility of the supervision for AEFI in our district is fairly good. Normal events occupied the most events in the situation of AEFI, while serious event has never occured. Nevertheless, more promotion, correct guidance are also needed. Additionally, more training and better management must be taken into agenda to enhance the sensibility of supervision and the quality of preventive inoculation.
