摘要

2024 年 6 月底,欧洲药品管理局(EMA)建议批准基于 JN.1 穗状病毒的单价 COVID-19 mRNA 疫苗上市。我们评估了 n=42 名医护人员(中位年龄 47 岁,四分位数间距 19-5 岁,48% 为男性)的免疫反应,他们于 2024 年 8 月接种了 30 μg 更新的 mRNA omicron JN.1 疫苗(bretovameran,BioNTech/辉瑞,德国美因茨)。接种前和接种后 13 天直接分析体液免疫反应。

Humoral Immunity after mRNA Omicron JN.1 Vaccination
In late June 2024, the European Medicines Agency (EMA) recommended market authorization for a monovalent COVID-19 mRNA-vaccine based on JN.1 spike. We assessed immune responses in n=42 health-care workers (median age 47 years, interquartile range, IQR 19·5 years, 48% male), who in August 2024 were vaccinated with 30 μg of the updated mRNA omicron JN.1 vaccine (bretovameran, BioNTech/Pfizer, Mainz, Germany). Humoral immune responses were analyzed directly prior to and 13 days after vaccination.
