Abstract

Objective: To understand the coverage and information consistency rate of National Immunization Program (NIP) vaccines among children born during 2020-2021 in Zhejiang Province, Chongqing City, and Shanxi Province (3 provinces) of China. Methods: A simple random sampling method was used to randomly select 3 counties (districts) from each of the 3 provinces, 5 townships from each county (district), and 5 villages from each township. Vaccination information for seven NIP vaccines was collected for children born between 2020 and 2021 in each village. The vaccination coverage, timely coverage, and consistency rates between the survey data and the Immunization Planning Information System data were analyzed. Results: A total of 1 117 children were investigated. The vaccination coverage for each dose of NIP vaccine ranged from 99.10% to 100.00%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 99.19% to 100.00%, 98.92% to 100.00%, and 99.20% to 100.00%, respectively. The timely coverage of each dose of NIP vaccine ranged from 89.79% to 99.82%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 94.09% to 99.73%, 89.52% to 99.73%, and 78.55% to 100.00%, respectively. The consistency rate of information on each dose of NIP vaccine ranged from 94.36% to 99.91%, with those in Zhejiang Province, Chongqing City, and Shanxi Province ranging from 97.85% to 99.73%, 98.92% to 100.00%, and 86.06% to 100.00%, respectively. Conclusions: Coverage of NIP vaccines was generally high among children born during 2020-2021 in the 3 provinces of China, but there were regional differences in the timely coverage of some vaccine doses and the vaccination information consistency rate. It is necessary to strengthen the timely vaccination of children's vaccine booster doses and optimize the management of vaccination services.

[中国3省2020-2021年出生儿童国家免疫规划疫苗覆盖率及疫苗接种信息符合率]。

目的：了解浙江省、重庆市和山西省（3省）2020-2021年出生儿童国家免疫规划（NIP）疫苗接种率和信息一致性。方法：采用简单随机抽样的方法，在3个省中每个省随机抽取3个县（区），每个县（区）随机抽取5个乡，每个乡随机抽取5个村。为每个村庄在2020年至2021年期间出生的儿童收集了7种NIP疫苗的接种信息。分析疫苗接种覆盖率、及时覆盖率以及调查数据与免疫规划信息系统数据的一致性。结果：共调查1 117例儿童。NIP疫苗每剂接种率为99.10% ~ 100.00%，其中浙江省、重庆市和山西省接种率分别为99.19% ~ 100.00%、98.92% ~ 100.00%和99.20% ~ 100.00%。NIP疫苗每剂接种率为89.79% ~ 99.82%，其中浙江省、重庆市和山西省接种率分别为94.09% ~ 99.73%、89.52% ~ 99.73%和78.55% ~ 100.00%。每剂疫苗信息的符合率为94.36% ~ 99.91%，其中浙江省为97.85% ~ 99.73%，重庆市为98.92% ~ 100.00%，山西省为86.06% ~ 100.00%。结论：中国3省2020-2021年出生儿童NIP疫苗接种率普遍较高，但部分疫苗剂量的及时接种率和接种信息一致性存在地区差异。要加强儿童疫苗加强剂的及时接种，优化接种服务管理。
