The first group of human test subjects for a new COVID-19 vaccine developed by the Chinese military have returned home following the completion of 14-day quarantine period.
On 31 March a total of four vaccine testing volunteers completed the observation period for a novel coronavirus vaccine and returned home from a military medical testing centre in Wuhan, according to a report from The.Paper.cn.
All four of the volunteers were subject to a 14-day quarantine and observation period after receiving the vaccine on 16 March, and provided blood samples on the 7th and final day of their confinement.
According to a report from Science and Technology Daily a total of 108 volunteers are participating in stage 1 testing of the trial novel coronavirus vaccine, all of whom are permanent residents of the Wuhan area.
The Academy of Military Medical Sciences and Hong Kong-listed CanSino Bio-B are responsible for holding the trials, according to information from the Chinese Clinical Trial Registry.
The stage 1 test participants are divided into three groups – a low dose group, a medium dose group and a high dose group. Each group is comprised of 36 volunteers.
According to Science and Technology Daily the vaccine was developed via genetic engineering, using replication-defective human type 5 adenovirus as a vector and expressing the new coronavirus S antigen.
