The first experimental Covid-19 vaccine produced antibodies

Injecting the nCoV antigen test, the mouse's body has a good immune response, producing antibodies, promising initial success in creating a vaccine against Covid-19.

In the afternoon of February 22, Zhejiang Department of Science and Technology held a press conference to announce the control of Wuhan pneumonia. Representatives of the research team said that the first vaccine group in Zhejiang province produced antibodies. The researchers screened nCoV over four generations. The recombinant vaccine on conductors, beginning with viral culture, is currently being tested on animals.

According to experts, usually in vaccines will contain a certain amount of pathogenic antigen, when injected into animals, if a good immune response will produce antibodies against that antigen to protect the body. This result promises a good vaccine.

Currently, the team is working with the Centers for Disease Control and Prevention, Zhejiang University Hospital to develop Covid-19 vaccines such as viral activity reduction vaccine, recombinant protein vaccine, vaccine Recombinant adenovirus, mRNA vaccine .

For recombinant protein vaccines, the antigens are produced by the first test group. Research and development of the mRNA vaccine has entered an experimental phase in animals, the recombinant adenovirus vaccine has begun to expand the culture of recombinant viruses and animal experiments.

Song Zhiheng, deputy director of Zhejiang Provincial Department of Science and Technology, said that since the outbreak, researchers have been constantly investigating and tracing the origin of new strain of corona virus, perfecting the treatment regimen. treating, developing preventive vaccines, conducting six nCoV research projects and three scientific funds to support research.

Earlier, on February 19, a team of researchers at West Lake University, Zhejiang Province published a successful analysis of the ACE2 cell receptor structure in nCoV, which plays an important role in the detection and optimization. chemical inhibitors prevent nCoV from entering.

Positive results from the first vaccine group increase confidence in the ability to win the disease. The Covid-19 epidemic has been reported in 30 countries and territories around the world, causing more than 77,600 people to be infected and 2,360 to die.
