On May 7, according to media reports,The new research team from China published in science reveals the animal experimental results of the new coronavirus vaccine, which is also the first published animal experimental results。
The study, led by the team of Qin Chuan of the Chinese Academy of Medical Sciences and co-organized by Beijing Kexing Biological Products Co., Ltd. and the Institute of Medical Experimental Animals of the Chinese Academy of Medical Sciences, produced a candidate vaccine for purified and inactivated SARS-CoV-2 virus called PiCoVacc., the report said
PiCoVacc, researchers producing experimental scale for animal research bred them in 50 liters Vero cell culture and used them
They found that,Picovacc can induce effective humoral immune response in non-human primates and provide complete protection for the sars-cov-2 virus strain which is currently raging in the world. Based on the systematic analysis of the clinical signs, hematology and biochemical indexes of rhesus monkeys, the researchers believe that the vaccine is safe.
it is understood that a variety of SARS-CoV-2 vaccines are being developed, such as DNA、RNA vaccines, recombinant subunit vaccines containing viral epitopes, adenovirus vector vaccines, and purified inactivated virus vaccines. At present, three domestic vaccines have been approved into clinical trials, one of the adenovirus vector vaccine has entered the II phase of human clinical trials.
