突破病例
breakthrough infections

中国疾控中心研究员、科研攻关组疫苗研发专班专家组成员邵一鸣表示，

It is not surprising to see breakthrough infections－people who contract the virus at least 14 days after being fully vaccinated－because no vaccine is capable of totally preventing people from catching the virus.
完成疫苗接种至少14天后又被感染的病例被称为“突破病例”，这并不是例外，因为没有疫苗能够百分之百防止人们感染病毒。
