The first experimental Covid-19 vaccine has produced antibodies
China has tested Covid-19 antigens on mice, and the mice have responded well to the immune system, producing antibodies, promising initial success in creating a Covid-19 vaccine.

On the afternoon of February 22, the Department of Science and Technology of Zhejiang Province held a press conference to announce the situation of controlling the Wuhan pneumonia epidemic. A representative of the research team said that the first group of vaccines in Zhejiang Province had produced antibodies. Researchers have screened Covid-19 through 4 generations. The vaccine was recombinant on a conductor, starting from virus culture, and is currently being tested on animals.
According to experts, vaccines usually contain a certain amount of pathogenic antigens. When injected into animals, if the immune response is good, antibodies will be produced against that antigen to protect the body. This result promises a good vaccine.
Currently, the research team is collaborating with the Provincial Center for Disease Control and Prevention and Zhejiang University Hospital to develop vaccines to treat Covid-19 such as inactivated virus vaccines, recombinant protein vaccines, recombinant adenovirus vaccines, and mRNA vaccines.
For recombinant protein vaccines, the antigens are produced by the first pre-trial group. The research and development of mRNA vaccines has entered the animal testing stage, and the recombinant adenovirus vaccine has begun to expand the recombinant virus culture and animal experiments.
Mr. Song Zhiheng - Deputy Director of the Department of Science and Technology of Zhejiang Province said that since the outbreak, researchers have continuously studied and traced the origin of the new strain of Corona virus, perfected treatment regimens, developed preventive vaccines, conducted 6 Covid-19 research projects and 3 scientific funds to support research.
Previously, on February 19, a research team from West Lake University, Zhejiang Province, announced the successful analysis of the 3D structure of the ACE2 cell receptor in Covid-19, which plays an important role in detecting and optimizing inhibitors to prevent the penetration of Covid-19.
Positive results from the first group of vaccines have increased confidence in the ability to defeat the epidemic. Covid-19 has appeared in 30 countries and territories around the world, infecting more than 77,600 people and killing 2,360.
