Abstract

Objective: A decline in routine vaccination coverage in children has been observed after the onset of the COVID-19 pandemic, but it is unclear whether these declines were sustained over time. This analysis assessed changes in vaccination coverage at ages 2 and 7 years for routinely administered vaccinations before, during, and after the COVID-19 pandemic.

Methods: Vaccination coverage was measured using yearly data from the Standardized Reporting on Vaccination (STARVAX) surveillance system between December 31, 2019, and December 31, 2023. Four provinces (Alberta, Saskatchewan, Manitoba, and New Brunswick) and one territory (Yukon) produced reports from their immunization registries and provided the Public Health Agency of Canada with the numbers of vaccinated 2-year-old and 7-year-old children. Population estimates from Statistics Canada and the Yukon Bureau of Statistics were used as the denominators.

Results: There was a decline in vaccination coverage in 2023 compared to 2019. In 2-year-olds, coverage for one dose of the measles, mumps, and rubella (MMR) vaccine and four doses of the diphtheria, tetanus, and acellular pertussis (DTaP) vaccine decreased from 89.5% to 82.5% and from 79.9% to 72.1%, respectively. Among 7-year-olds, DTaP (up-to-date) and MMR (two doses) vaccination coverage decreased from 77.1% to 68.8% and 86.3% to 75.6%, respectively.

Conclusion: These declines are of concern and suggest that health care professionals should provide parents with accurate information regarding vaccines and encourage them to have their children vaccinated and keep vaccinations up to date.

在 COVID-19 大流行之前、期间和之后，2 岁和 7 岁儿童的常规疫苗接种覆盖率：STARVAX 监测系统的结果。

目的：COVID-19 大流行后，儿童常规疫苗接种覆盖率有所下降，但目前尚不清楚这种下降是否会随着时间的推移而持续。本分析评估了 COVID-19 大流行之前、期间和之后 2 岁和 7 岁常规接种疫苗覆盖率的变化：方法：使用疫苗接种标准化报告（STARVAX）监测系统提供的 2019 年 12 月 31 日至 2023 年 12 月 31 日期间的年度数据来衡量疫苗接种覆盖率。四个省份（艾伯塔省、萨斯喀彻温省、马尼托巴省和新不伦瑞克省）和一个地区（育空地区）从其免疫登记处提供了报告，并向加拿大公共卫生署提供了接种疫苗的 2 岁和 7 岁儿童人数。加拿大统计局和育空地区统计局的人口估计数被用作分母：与 2019 年相比，2023 年的疫苗接种覆盖率有所下降。在 2 岁儿童中，一剂麻疹、腮腺炎和风疹（MMR）疫苗以及四剂白喉、破伤风和无细胞百日咳（DTaP）疫苗的接种率分别从 89.5% 降至 82.5%，从 79.9% 降至 72.1%。在 7 岁儿童中，白破疫苗（最新）和麻腮风疫苗（两剂）的接种率分别从 77.1%降至 68.8%和从 86.3% 降至 75.6%：这些下降令人担忧，并表明医疗保健专业人员应向家长提供有关疫苗的准确信息，鼓励他们为孩子接种疫苗并保持疫苗接种的及时性。
