Abstract:
Objective To analyze the current status of influenza vaccination in Liaoning Province from 2014 to 2024, and provide a basis for formulating population influenza prevention and control strategies.Methods The information related to influenza vaccine was collected, and the influenza vaccination data in Liaoning Province were derived through “China Immunization Program Information Management System” and “Liaoning Province Immunization Program Comprehensive Information Platform-Vaccination Information System” to analyze the current situation and characteristics of influenza vaccination from 2014 to 2024.Results From 2014 to 2024, the number of per capita doses of influenza vaccine in Liaoning Province showed an upward trend, reaching 348. 96 doses per 10 000 people in 2023, with a month-on-month increase of119. 40%. The proportion of influenza vaccinations in non-immunization program vaccinations increased from 6. 91% in2018 to 32. 19% in 2023. Starting from 2019, influenza vaccines with different technical routes have been included in the reporting scope. The quadrivalent influenza split vaccine accounted for 67. 40% of the total influenza vaccination of all varieties, and the proportion of vaccination in 2024 was as high as 82. 83%. Regional distribution showed that the number of influenza vaccination doses was the highest in Dalian(1 679 818 doses), followed by Shenyang(1 284 318 doses). The vaccination rate was the highest in Dalian(2. 55%), followed by Benxi(2. 17%) and Shenyang(1. 56%). Influenza vaccination time was mainly concentrated from August to December, accounting for 96. 14% of the annual vaccination times.Conclusion The number of per capita vaccinations of influenza vaccine in Liaoning Province shows a rapid growth trend,which reflects the gradual improvement of public awareness of health and the positive effects of public health interventions.However, there are still low vaccination rates and regional differences. In addition to strengthening publicity and promotion,it is suggested to further improve the overall vaccination rate of influenza vaccine through policy guidance, prevent influenza more efficiently and reduce the burden of diseases.
