Study design:

Single arm 

研究目的:

主要目的:探究血清与鼻黏膜中抗体关联关系,阐明系统和黏膜在免疫应答中的独立性与关联性,探索其免疫学替代终点; 次要目的:评价血清和鼻黏膜中细胞因子和先天与适应性免疫模块的关联关系以及鼻喷流感疫苗在黏膜和系统层面诱导的细胞因子、抗体及关键免疫细胞亚群的时序变化,识别免疫应答中早期激活与记忆形成相关的关键细胞亚群与信号通路。  

Objectives of Study:

Primary objective: To explore the correlative relationships of antibodies in serum and nasal mucosa, clarify the independence and correlation of systemic and mucosal immune responses, and investigate their immunological surrogate endpoints. Secondary objectives: To evaluate the correlative relationships of cytokines and innate and adaptive immune modules in serum and nasal mucosa, as well as the temporal changes of cytokines, antibodies, and key immune cell subsets induced by the nasal spray influenza vaccine at both mucosal and systemic levels, and to identify the key cell subsets and signaling pathways related to early activation and memory formation in immune responses.

Sample size:

干预措施:

按标示量加入疫苗稀释剂,待疫苗溶解并摇匀后使用。用注射器抽取至少 0.2 ml 复溶后疫苗,取下针头,安装鼻喷装置。受种者采取头部向后仰的坐姿,将鼻喷装置放置受种者鼻内约 0.5 cm 处喷雾接种,每侧鼻孔内喷 0.1 ml。接种后,受种者应头部向后仰坐姿至少 1 分钟。

干预措施代码:

Intervention:

Add the vaccine diluent as indicated on the label. After the vaccine is dissolved and shaken well, it is ready for use. Draw at least 0.2 ml of the reconstituted vaccine with a syringe, remove the needle, and attach the nasal spray device. The recipient should sit with their head tilted back. Place the nasal spray device approximately 0.5 cm inside the recipient's nostril and administer the spray, with 0.1 ml sprayed into each nostril. After vaccination, the recipient should maintain the sitting position with their head tilted back for at least 1 minute.
