新型冠状病毒灭活疫苗接种后的针后贴和受种者手部标本核酸检测情况的研究

Research study on nucleic acid testing of hemostatic stickers used and the surface of the recipients′hands after the inoculation of inactivated SARS-CoV-2 vaccine

从2021年1月30日接种新型冠状病毒灭活疫苗的首都医科大学附属北京朝阳医院工作人员中选择28位受试者作为研究对象进行研究,在疫苗接种前后分别对受种者的双手进行采样核酸检测的同时,对接种疫苗后粘贴在接种部位的针后贴进行核酸检测。接种疫苗前,受种者双手表面采集的标本核酸检测结果均为阴性。接种疫苗后,受种者双手表面采集的标本核酸检测结果阳性共3例,核酸检测结果可疑共8例,阳性率占10.7%;共收集25例使用过的针后贴标本,核酸检测结果阳性24例,核酸检测结果可疑1例,阳性率占96%。新型冠状病毒灭活疫苗接种的针后贴存在核酸污染的风险。

Among the staff of Beijing Chao-Yang Hospital,Capital Medical University,who received the inactivated SARS-CoV-2 vaccine on January 30 in 2021,28 recipients were selected for this research.Samples for nucleic acid tests were collected from the surface of the recipients′both hands before and after vaccination.The hemostatic stickers used after the inoculation were also collected for nucleic acid tests.The nucleic acid tests of the samples collected from the surface of both hands of the 28 recipients before vaccination were all negative.After vaccination,the nucleic acid tests of the samples collected from the surface of both hands of recipients were positive in 3 cases,and suspicious in 8 cases,with a positive rate of 10.7%.A total of 25 hemostatic stickers used were collected,24 of them had positive nucleic acid tests,and the rest one had suspicious nucleic acid test result,with a positive rate of 96%.The hemostatic stickers used after the inoculation have the risk of nucleic acid contamination.
