We report 11 cases of SARS-CoV-2 infection in healthcare workers (HCW) for COVID-19 and seropositive after the second dose of the BNT162b2 mRNA vaccine. Based on voluntary-based surveillance, they tested positive for different strains of SARS-CoV-2, as Spike gene sequencing showed. Five of them reported mild symptoms. Given the risk for SARS-CoV-2 introduction from asymptomatic vaccinees, this case series suggests the need to continue nasopharyngeal screening programmes.
我们报告了 11 例 COVID-19 期间 SARS-CoV-2 感染的医护人员（HCW），他们在接种第二剂 BNT162b2 mRNA 疫苗后血清呈阳性。基于自愿监测，根据 Spike 基因测序显示，他们感染了不同的 SARS-CoV-2 毒株。其中 5 人报告有轻微症状。鉴于无症状疫苗接种者引入 SARS-CoV-2 的风险，本病例系列表明需要继续进行鼻咽筛查计划。
