Abstract:Objective To analyze the surveillance of adverse event following immunization (AEFI) among 8-month-old children in Jiaxing who received measles, mumps and rubella combined attenuated live vaccine (MMR) or measles and rubella combined attenuated live vaccine (MR) , so as to provide support for the adjustment of vaccine immunization strategy.Methods The AEFI information of MR (December 1, 2016 to April 30, 2018) and MMR (December 1, 2018 to April 30, 2020) was collected through National AEFI Monitoring Information Management System to compare the incidence, clinical features, occurred time of AEFI as well as combined vaccination.Results Totally 94 287 doses of MR and 79 994 doses of MMR were administered, 145 and 156 cases of AEFI were reported, and the incidence rate was 15.38/10 000 after MR vaccination, which was lower than 19.50/10 000 after MMR vaccination (P<0.05). Most reported AEFI were abnormal reactions, with 93 cases (11.63/10 000) after MR vaccination and 101 cases (10.71/10 000) after MMR vaccination, among which 72 cases (7.64/10 000) and 76 cases (9.50/10 000) respectively had allergic rash. The AEFI cases mainly occurred less than one day after vaccination, with 113 cases (77.93%) after MR vaccination and 125 cases (80.13%) after MMR vaccination. Most cases of AEFI were vaccinated with Japanese encephalitis attenuated live vaccine (JEV), with 103 cases (71.03%) after MR vaccination and 102 cases (65.38%) after MMR vaccination.Conclusions The MMR is safety for 8-month-old children in Jiaxing. Most AEFI cases had abnormal reactions, occur within one day after vaccination, and are vaccinated with JEV.
