中国科学院院士、中国科学院微生物研究所研究员、会议执行主席高福表示，呼吸道病毒疫苗保护 率普遍不高成为疾病防控的"痼疾"，由于黏膜位于抗呼吸道病毒感染的前线，因此对黏膜区域免疫应答 反应的研究将对呼吸道疾病防控起到至关重要的作用。 "接种乙肝疫苗的人群，极少会被乙肝病毒感染；但接种了呼吸道病毒疫苗的人，却仍有不少会被 呼吸道病毒感染。"4月8日至9日，第778次香山科学会议召开"肺脏与呼吸道黏膜区域免疫：挑战与机 遇"主题学术讨论会，中国科学院院士、中国人民解放军总医院第五医学中心教授王福生解释了呼吸道 病毒疫苗保护率普遍不高的原因：在人体内，乙肝病毒需长途跋涉才能到达肝脏细胞，这一过程中它会 被疫苗激发的保护性抗体和免疫细胞消灭；而呼吸道病毒攻击开放系统，在人"一呼一吸"间感染细胞， 此时肌肉注射疫苗产生的抗体还在血液里，远离防守"最前线"。 筑牢头道屏障 "呼吸道黏膜是抵御包括细菌、病毒和真菌等病原体的第一道天然屏障，通过物理屏障和免疫功能 保护机体。"广州医科大学基础医学院教授赵金存解释，黏膜免疫能通过调动免疫应答、启动免疫协作 等手段"制伏"病原体。 中国科学院微生物研究所研究员王硕补充道，研究还发现 ...
