Among 8,678 vaccinated healthcare personnel (HCP) with previous coronavirus disease 2019 (COVID-19), by August 28, 2023, 909 (10%) had an infection of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) omicron XBB variant. Reinfection risk was comparable irrespective of previous infection type except for the omicron BQ.1 variant. Bivalent vaccination had a protective effect. COVID-19 vaccines remain vital to protect HCP, including those with hybrid immunity.

具有严重急性呼吸道冠状病毒2(SARS-CoV-2)混合免疫的医护人员对XBB谱系再感染的易感性

截至 2023 年 8 月 28 日,在 8,678 名曾患有 2019 年冠状病毒病 (COVID-19) 且已接种疫苗的医护人员 (HCP) 中,有 909 名 (10%) 感染了严重急性呼吸道冠状病毒 2 (SARS-CoV-2) omicron XBB 变种。除 omicron BQ.1 变体外,无论先前的感染类型如何,再感染风险都相当。二价疫苗接种具有保护作用。COVID-19 疫苗对于保护 HCP(包括具有混合免疫能力的 HCP)仍然至关重要。
