Chinese authorities have approved the clinical trials on the efficacy and safety of domestic mRNA booster for inactivated vaccines, according to media reports on Wednesday.
 

The project has been approved by the disease control and prevention center of South China's Guangxi Zhuang Autonomous Region. It will focus on people aged 18 and above who have been inoculated with two inactivated vaccine shots, according to the announcement on the website of the Ministry of Science and Technology.
 

The mRNA candidate shot to be used in the trials is called ARCoVax, which was jointly developed by the Academy of Military Medical Sciences, Suzhou Abogen and Yunnan Walvax Biotechnology Co, media confirmed on Wednesday.
 

Zhang Li, spokesperson from Walvax, said that the project is part of the Phase III clinical trials of ARCoVax, which is being conducted both in Guangxi and abroad, including Mexico and Indonesia.
 

On Saturday, Walvax's partner Suzhou Abogen already informed that their mRNA vaccine production line located in an industry park in Suzhou had obtained official authorization. The facility is able to produce 40 million shots per year.
 

The storage costs of this vaccine are lower than imported shots as it comes in a single injection in one package and can be stored at room temperature for a week or at 4 C for an extended time making it easier to use.
 

国产mRNA疫苗被批准用于加强针试验

在新冠疫苗的五大技术路线中,mRNA疫苗属于最新一代的技术,国外的两款mRNA疫苗保护率在95%左右,国产的mRNA疫苗号称效果不输国外产品,不过国内的进度比国外略慢一些,最新的研究是作为加强针使用。
 

据报道,根据科技部政府服务平台信息显示,“评价新型冠状病毒mRNA疫苗在18~59岁和60岁及以上已接种新型冠状病毒灭活疫苗人群中加强接种的免疫原性和安全性的IIIb期临床试验”获批准。
 

申请单位为广西壮族自治区疾病预防控制中心,批准时间为2021年11月。目前国内的mRNA疫苗厂商主要涉及艾博生物、沃森生物、斯微生物等
