Abstract
We report an outbreak of severe acute respiratory syndrome coronavirus 2 501Y.V2 in a nursing home. All nonvaccinated residents (5/5) versus half of those vaccinated with BNT162b2 (13/26) were infected. Two of 13 vaccinated versus 4 of 5 nonvaccinated residents presented severe disease. BNT162b2 did not prevent the outbreak, but reduced transmission and disease severity.
摘要
我们报告了一起严重急性呼吸综合征冠状病毒 2 501Y.V2 在一家养老院的爆发。所有未接种疫苗的居民（5/5）与接种 BNT162b2 的居民的一半（13/26）相比都被感染了。在接种疫苗的 13 人中，有 2 人出现严重疾病，而在未接种疫苗的 5 人中，有 4 人出现严重疾病。BNT162b2 并未阻止此次爆发，但降低了传播和疾病的严重程度。
