概括
基细胞激活测试 (BAT) 不能预测对COVID-19 mRNA疫苗 (BNT162b2) 的过敏反应. 以前的疫苗接种史可能会混 BAT 结果,因此需要进一步研究以准确预测mRNA疫苗接种者的过敏情况.
科学领域:
- 免疫学 免疫学 免疫学
- 疫苗学 疫苗学 疫苗学
背景情况:
- 对mRNA COVID-19疫苗 (BNT162b2) 的过敏反应引起了人们对疫苗犹的担忧.
- 对mRNA疫苗过敏的准确预测测试对于患者护理和mRNA技术的进步至关重要.
研究的目的:
- 评估基细胞激活试验 (BATs) 在预测BNT162b2 COVID-19疫苗过敏反应方面的实用性.
主要方法:
- 从经历过敏反应的个人 (COVAAR试验) 和健康志愿者收集血液样本.
- 用BNT162b2疫苗或其组分,五克里斯托伊尔甘-聚乙烯甘2000的化后,通过流细胞计测量使用CD63表达来测量基因细胞激活.
- 组间对抗活性进行了比较,并与疫苗接种史和自最后一剂/感染以来的时间进行了分析.
主要成果:
- 与健康志愿者相比,患有过敏反应的参与者对疫苗或其组件的基因细胞反应并没有显著增加.
- 基细胞的反应性与上次疫苗注射或之前的COVID-19感染以来的时间无关.
- 在接受过两剂或更多剂量疫苗的个体中,无论过敏反应史有没有过敏反应,都观察到基细胞的活性增加.
结论:

The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
