When and if the world has a COVID-19 vaccine, who should get it first? That question came into sharp relief last week as the World Health Organization and U.S. Centers for Disease Control and Prevention began to publicly discuss priority groups such as the elderly and health care workers. New data suggested how fraught any prioritization is likely to be: Pregnant women—normally the last to receive a new vaccine, given the possibility of harm to a fetus—may have an increased risk of severe illness from COVID-19, suggesting they should be high on the list.

何时以及如果世界上有 COVID-19 疫苗，谁应该先接种？上周，随着世界卫生组织和美国疾病控制与预防中心开始公开讨论老年人和医护人员等优先群体，这个问题得到了极大的缓解。新数据表明，任何优先事项可能有多么令人担忧：孕妇——鉴于可能对胎儿造成伤害，通常是最后一个接种新疫苗的人——可能会增加因 COVID-19 而患上严重疾病的风险，这表明她们应该名列前茅。
