Abstract:Objective To understand the differences in the surveillance data regarding adverse event following immunization (AEFI) between routine immunization and supplementary immunization activities of measles-containing vaccine (MCV) in Hebei Province during 2010-2018, and to provide a scientific basis for optimizing MCV supplementary immunization strategy. Methods We collected the data about AEFI cases, routine vaccination and supplementary immunization of MCV specially-reported by each city in Henan Province during 2010-2018 through the National Immunization Program Information Management System. Descriptive epidemiological method was used to statistically analyze the characteristics of AEFI surveillance after routine immunization and supplementary immunization of MCV. Results A total of 9,352 AEFI cases after routine immunization of MCV and 2,590 AEFI cases after supplementary immunization of MCV were reported in Hebei Province from 2010 to 2018. The reported incidence rates of total AEFI, common adverse reactions and rare adverse reactions after routine immunization were 47.81/100,000 doses, 45.31/100,000 doses and 2.32/100,000 doses, respectively, while the above-mentioned incidence rates after supplementary immunization were 64.40/100,000 doses, 54.03/100,000 doses and 9.08/100,000 doses, respectively. Among severe adverse reactions, the reported incidence rates of febrile convulsions, thrombocytopenia and acute severe anaphylaxis after routine immunization were 0.07/100,000 doses, 0.16/100,000 doses and 0.02/100,000 doses, respectively, whereas the above-mentioned incidence rates after supplementary immunization were 0.35/100,000 doses, 0.07/100,000 doses and 0.15/100,000 doses, respectively. Conclusion AEFI after routine immunization and supplementary immunization of MCV in Hebei Province during 2010-2018 was mainly common vaccine reactions, and severe reactions were extremely rare. MCV in Hebei Province is safe.
