Abstract
Highlight (Word Count: 49): We conducted contact-tracing investigation of multiple patients and healthcare workers exposed to a pre-symptomatic physician, triple-vaccinated with BNT162b2 COVID-19 vaccine, infected with SARS-CoV-2 B.1.1.529 (Omicron) Variant. Of 51 contacts, 45(88%) were triple-vaccinated (boosted) with BNT162b2 vaccine and 47(92%) contacts were masked. One (1/51, 2%) triple-vaccinated primary contact became infected.
摘要
突出显示（字数：49）：我们对多名接触过一位有症状前的医生的患者和医护人员进行了接触者追踪调查，该医生接种了三剂 BNT162b2 COVID-19 疫苗，感染了 SARS-CoV-2 B.1.1.529（奥密克戎）变体。在 51 名接触者中，45 名（88%）接种了三剂（加强剂）BNT162b2 疫苗，47 名（92%）接触者戴了口罩。一名（1/51，2%）接种了三剂的初级接触者感染。
