OBJECTIVE To analyze the epidemiological characteristics of adverse events following immunization(AEFI) in Binhai New Area,Tianjin,2019.METHODS For descriptive epidemiological analyses,it collected AEFI case data through the National Immunization Program Information Management System,and vaccine doses-administered data from Tianjin Immunization Program Information System.RESULTS 447 AEFI cases were reported.The reported AEFI incidence was 81.43 per 100 000 doses,79.42% were common vaccine reactions(355 cases),18.75% were rare vaccine reactions(84 cases).The reported AEFI incidence were 64.67 per 100 000 doses and 15.30 per 100000 doses respectively,the male to female ratio was 1.32:1,73.15% were among children less than 1 years old.The top 3 districts are Hangzhoudao Street,Dagu Street and TangGu Street.Most cases occurred in the third and fourth quarter.The top 5 AEFI incidence were Human Papillomavirus 9-valent,Recombinant vaccine(769.23 per 100 000 doses),Measles and rubella combined attenuated live vaccine(316.74 per 100 000 doses),Human Papillomavirus 4-valent,Recombinant vaccine(302.11 per100 000 doses),Diphtheria,tetanus and acellular pertussis,inactivated poliovirus and Haemophilusinfluenzae type b conjugate combined vaccine(271.66 per 100 000 doses) Diphtheria,tetanus and acellular pertussis and Hhaemophilus influenza type b conjugate combined vaccine(225.62 per 100 000 doses).By comparison,there were statistical differences in the incidence rates of 3 DTaP-containing vaccines(χ^2=27.463,P<0.001) CONCLUSIONS Most AEFIs were common vaccine reactions in Tianjin Binhai New Area in 2019,which showed the vaccine was safe.
