Analysis of influenza vaccination rate and safety of children aged 6 months to 5 years in Shijingshan District of Beijing from 2019 to 2023
Objective To analyze the situation of influenza vaccination and adverse event following immunization(AEFI)in children aged 6 months to 5 years old in Shijingshan District of Beijing from 2019 to 2023,in order to provide better reference for the prevention and control of influenza epidemics in children and the vaccination of influenza vaccines.Methods The influenza vaccination data of children aged 6 months to 5 years in Shijingshan District of Beijing from September 2019 to March 2023 were collected and analyzed through Beijing Immunization Planning Information Management System and the China Disease Prevention and Control Information System.Results From 2019 to 2023,a total of 7 566 children aged 6 months to 5 years old in Shijingshan District of Beijing were vaccinated with influenza vaccine,with 10 347 doses administered.The average annual vaccination rate was 7.06％,and the vaccination rate ranged from 2.00％to 9.90％in each year over the four-year period.The difference in vaccination rate between different years was statistically significant(P＜0.05),and the vaccination rate showed a trend of increasing year by year(x2trend=1 472.596,P＜0.05).The vaccination ratio of male to female students was 1.06∶1,and there was a statistically significant difference in the vaccination rate between males and females(P＜0.05).The vaccination rates of different age groups showed an increasing trend year by year(x2trend=3 336.878,P＜0.05),and there were statistically significant differences in vaccination rates among different age groups in different years(P＜0.05).The vaccination rates for children aged 6 months to 5 years in the eastern,central,and western regions were 8.97％,8.06％,and 3.22％,respectively.There was a statistically significant difference in vaccination rates among the three regions(P＜0.05),and the vaccination rates showed a gradually increasing trend from west to east(x2trend=664.323,P＜0.05).There were statistically significant differences in vaccination rates among different regions in different years(all P＜0.05).Five cases(2.87％)of influenza vaccine AEFI were reported in children aged 6 months to 5 years,with a reported incidence rate of 48.32/100 000 doses.Conclusion The vaccination rate of influenza vaccine in 6 month to 5 year old children group in Shijingshan District of Beijing from 2019 to 2023 is relatively low,and AEFI reporting rate is significantly higher than other populations.It is necessary to further strengthen publicity and education to help children and their parents form a correct understanding,so as to increase the influenza vaccination rate,and also to improve the professional quality of staff to reduce the occurrence of AEFI.
