研究目的:

本研究旨在从SARS-CoV-2抗体、细胞因子和不良反应等方面评估疫苗接种者血浆对临床用血患者免后30天的影响。根据研究结果综合评估血浆输注的最佳效价、探讨抗体的持久性和特殊人群免疫效果、掌握受体的免疫学和代谢状况、阐明输注异体抗体后机体的免疫机制并评判该方法的应用性和安全性。同时,通过卫生经济学评价探讨输注疫苗加强针接种者血浆相对于传统康复期患者血浆干预措施的优势及成本效果。  

Objectives of Study:

The aim of this study was to evaluate the effects of the plasma of vaccinated patients on 30 days after immunization in terms of SARS-CoV-2 antibodies, cytokines and adverse reactions. According to the results of the study, the optimal titer of plasma infusion was evaluated comprehensively, the persistence of the antibody and the immune effect of the special population were discussed, the immunological and metabolic status of the recipient was understood, the immune mechanism of the body after transfusion of allogeneic antibody was clarified, and the applicability and safety of the method was evaluated. At the same time, the advantages and cost-effectiveness of plasma intervention in patients with convalescent phase compared with plasma intervention in patients with vaccine-booster injection were discussed through health economics evaluation.

药物成份或治疗方案详述:

1.通过横断面调查,了解献血者献血意愿等影响因素,了解输血者用血意愿等影响因素。 2.通过RCT研究,向临床用血者输注疫苗接种者血浆进行干预,评估疫苗接种者血浆对临床用血患者免后30天的影响。 

Description for medicine or protocol of treatment in detail:

1. Through cross-sectional investigation, understand the influencing factors such as the willingness of blood donors to donate blood and the willingness of blood donors to use blood. 2. Through RCT study, the intervention was carried out by infusing the plasma of vaccinators into clinical blood users, and the influence of vaccinators' plasma on clinical blood patients 30 days after immunization was evaluated.

随机方法(请说明由何人用什么方法产生随机序列):

由科室独立统计师负责随机化(该统计师不参与项目其他工作) 采用PASS 11.0的随机分组模块系统抽样产生400个随机数字,对符合纳排标准的受试者通过随机数字分组,其中300名研究对象被随机分配到3个剂量组,另外100名研究对象被分配到阳性对照组。

Randomization Procedure (please state who generates the random number sequence and by what method):

Randomization by the department's independent statistician (who is not involved in other project work) The randomization module of PASS 11.0 was used to systematically sample 400 random numbers, and the subjects screened by the inclusion and exclusion criteria were grouped by random numbers, of which 300 subjects were randomly assigned to 3 dose groups, and the other 100 subjects were assigned to the positive control group.
