概括
在青少年中,较高的COVID-19疫苗剂量与SARS-CoV-2抗体标位的增加有关. 过敏性疾病在这个接种疫苗的青少年群体中没有显著影响抗体的产生.
科学领域:
- 免疫学 免疫学 免疫学
- 疫苗学 疫苗学 疫苗学
- 儿科健康 儿科健康
背景情况:
- 优化COVID-19疫苗接种策略需要了解影响青少年疫苗诱导免疫力的因素.
- 过敏疾病对青少年SARS-CoV-2mRNA疫苗抗体产生的影响尚未得到充分证实.
- 以Th2主导炎症为特征的过敏性疾病可能会改变免疫反应.
研究的目的:
- 在16至17岁的儿童接种mRNA疫苗后,确定影响SARS-CoV-2抗体标位的因素.
- 调查过敏疾病与对SARS-CoV-2mRNA疫苗的抗体反应之间的关联.
- 评估疫苗接种史对青少年抗体水平的影响.
主要方法:
- 分析了日本T-CHILD研究队列中的233名参与者的数据.
- 排除之前患有COVID-19感染 (血清学或历史) 的参与者.
- 检查SARS-CoV-2 S-抗体标位与疫苗接种细节,过敏状况和血清IgE水平之间的关联.
主要成果:
- 较多的疫苗剂量是增加SARS-CoV-2抗体标位的唯一独立预测因子.
- 没有观察到抗体标位与疫苗类型或自上次接种疫苗以来的时间之间有显著的关联.
- 过敏性疾病,包括喘,性皮肤炎和食物过敏,并没有显著影响抗体标位,也没有影响总血清IgE水平.
结论:
- 患有轻度过敏疾病的青少年对SARS-CoV-2mRNA疫苗表现出足够的免疫反应.
- 这些发现支持mRNACOVID-19疫苗接种在青少年中的安全性和有效性,无论常见的过敏状况如何.
- 疫苗接种策略可以自信地应用于患有过敏疾病的青少年群体.

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
