- Abstract: Objective To analyze the varicella vaccination rate in the 2012-2023 birth cohort in Changsha. Methods The varicella vaccination information of all children born in Changsha from 2012 to 2023 was collected through the Hunan Provincial Immunization Planning Information System. The varicella epidemic information from 2012 to 2023 was collected through the China Information System for Disease Control and Prevention. The varicella vaccination rate and its characteristics of children in the birth cohort were descriptively analyzed. Results The first dose vaccination rate of varicella vaccine for children born from 2012 to 2023 was 64.82 %, and the full vaccination rate was 40.87 %. The full vaccination rate of the birth cohort in each year ranged from 18.11 % (2020 birth cohort) -73.07 % (2017 birth cohort), showing an overall increasing trend year by year. Conclusion The varicella vaccination rate has increased among children born between 2012 and 2023 in Changsha, but overall coverage is low. It is necessary to strengthen the publicity of varicella vaccine knowledge and promote timely vaccination of school-age children.
