Abstract:
Objective :To evaluate the coverage and spatial clustering of 13-valent pneumococcal conjugate vaccine(PCV13) among the 2017—2023 birth cohorts in Anhui Province.
Methods :Obtained vaccination data of PCV13 for children born in 2017—2023 from the Anhui Immunization Information Management System.We estimated coverage levels and described characteristics of coverage.The spatial autocorrelation analysis of coverage was conducted.
Results :Cumulative coverage,cumulative primary immunization coverage and cumulative full-series coverage of PCV13 were 17.19%,12.12% and 9.09% among the 2017—2023 birth cohort in Anhui Province.The coverage of PCV13 increased from 1.14% in the 2017 birth cohort to 41.59% in the 2022 birth cohort.The first dose of PCV13 at ages under 3,3—6,7—11,12—23 and not less than 24 months were 45.35%,29.84%,5.52%,10.75% and 8.53%,respectively.There were significant differences in the ages of the first dose between children of different years of born and kinds of PCV13(P<0.001).Significant differences were also observed in the cumulative coverage,cumulative primary immunization coverage,cumulative full-series coverage of PCV13 and ages of the first dose among children from various residence regions(P<0.001).From 2018 to 2023 birth cohort,the coverage of PCV13 in Anhui Province showed obvious positive spatial autocorrelation.Local spatial autocorrelation analysis showed that the "high-high" agglomeration areas were concentrated in the central area of Anhui.
Conclusion:The coverage of PCV13 was low in Anhui Province with significant regional differences.
