伊什等人正确地提请人们注意世界各地在获得COVID-19疫苗接种方面的不平等。于2022年1月，低于10%生活于低收入国家的人士已接受至少一剂2019冠状病毒病（COVID-19）疫苗接种，而高收入及中上收入国家的比率则超过70%。1在低收入国家，将疫苗剂量导向初级课程计划，而在高收入国家，将疫苗剂量导向加强或延长初级课程计划，两者之间显然存在矛盾。世界卫生组织的立场是，在大流行的急性阶段，“疫苗接种计划的首要任务是降低死亡率和严重疾病，保护卫生系统”，其次是“预防轻微疾病和减少传播”。2虽然有针对性地使用加强剂或延长的初级疗程剂量满足了第一优先事项，但在低风险个体中全面使用这些剂量可能不会。正在进行的Omicron浪潮继续为疫苗接种策略提供信息，初步证据表明，在接种率高且既往暴露的人群中，疾病严重程度降低。
Ish et al. rightly draw attention to inequity in access to COVID-19 vaccinations around the world. In January 2022, less than 10% of people living in countries classified as low income have received at least one dose of coronavirus disease 2019 (COVID-19) vaccination compared to> 70% in high-and upper-middle-income countries. 1 There is clearly a tension between directing vaccine doses towards primary course programs in lower-income countries and booster or extended primary course programs in higher-income countries.The position of the World Health Organisation is that in the acute stage of the pandemic the ‘first priority of a vaccination program is to reduce mortality and severe disease and to protect health systems’, with ‘protection against mild disease and reduction of transmission’a secondary priority. 2 While the targeted use of booster or extended primary course doses fulfils the first priority, blanket use of these in low-risk individuals may not. The ongoing Omicron wave continues to inform vaccination strategy with preliminary evidence of reduced severity of illness in a population with high rates of vaccination and also prior exposure.
