With the availability of authorized COVID-19 vaccines in early 2021, vaccination became an effective tool to reduce COVID-19-associated morbidity and mortality. Initially, the World Health Organization (WHO) set an ambitious target to vaccinate 70% of the global population by mid-2022. However, in July 2022, WHO recommended that all countries, including those in the African Region, prioritize COVID-19 vaccination of high-risk groups, including older adults and health care workers, to have the greatest impact on morbidity and mortality. As of December 31, 2023, approximately 860 million doses of COVID-19 vaccine had been delivered to countries in the African Region, and 646 million doses had been administered. Cumulatively, 38% of the African Region's population had received ≥1 dose, 32% had completed a primary series, and 21% had received ≥1 booster dose. Cumulative total population coverage with ≥1 dose ranged by country from 0.3% to 89%. Coverage with the primary series among older age groups was 52% (range among countries = 15%-96%); primary series coverage among health care workers was 48% (range = 13%-99%). Although the COVID-19 public health emergency of international concern was declared over in May 2023, current WHO recommendations reinforce the need to vaccinate priority populations at highest risk for severe COVID-19 disease and death and build more sustainable programs by integrating COVID-19 vaccination into primary health care, strengthening immunization across the life course, and improving pandemic preparedness.
随着 2021 年初获得授权的 COVID-19 疫苗,接种疫苗成为减少 COVID-19 相关发病率和死亡率的有效工具。最初,世界卫生组织(WHO)设定了一个雄心勃勃的目标,即在 2022 年年中为全球 70%的人口接种疫苗。然而,在 2022 年 7 月,世卫组织建议所有国家,包括非洲区域的国家,优先为高风险人群(包括老年人和卫生保健工作者)接种 COVID-19 疫苗,以对发病率和死亡率产生最大影响。截至 2023 年 12 月 31 日,非洲区域各国已收到约 8.60 亿剂 COVID-19 疫苗,其中 6.46 亿剂已接种。累计有 38%的非洲区域人口已接种 ≥1 剂,32%已完成初级系列接种,21%已接种 ≥1 剂加强针。各国 ≥1 剂疫苗累计总人口覆盖率为 0.3%至 89%不等。老年人群组的初级系列接种覆盖率为 52%(各国范围为 15%-96%);卫生保健工作者的初级系列接种覆盖率为 48%(范围为 13%-99%)。尽管 2023 年 5 月宣布 COVID-19 国际关注的突发公共卫生事件结束,但世卫组织目前的建议强调需要为罹患 COVID-19 重症和死亡风险最高的优先人群接种疫苗,并通过将 COVID-19 疫苗接种纳入初级卫生保健、加强全生命周期免疫接种以及改善大流行防范,建立更可持续的计划。
