Abstract: Objective To analyze the characteristics of adverse events following immunization(AEFI) in Huangshan City from 2015 to 2020. Methods The case data of AEFI in Huangshan City from 2015 to 2020 were collected through the China AEFI monitoring information system,and the descriptive epidemiological methods was used for analysis. Results A total of 727 cases of AEFI were reported in Huangshan City from 2015 to 2020,with a reported incidence of 34.44/100 000,including 7 cases of severe AEFI,with a reported incidence of 0.33/100 000.The general reactions and abnormal reactions accounted for 89.00% and 10.45% respectively,and the reported incidence rates were 30.65/100 000 and 3.60/100 000,respectively.The general reactions were mainly fever,swelling and induration,while the abnormal reactions were mainly allergic rash and urticaria.The reported incidence in counties(38.45/100 000) was higher than that in urban areas(28.93/100 000),and the difference was statistically significant(χ2=13.534,P<0.01). Conclusions The incidence of AEFI in Huangshan City from 2015 to 2020 is within the expected range,mainly general reactions,and rare serious reactions.We should focus on strengthening the monitoring of AEFI in urban areas.
