The first experimental Covid-19 vaccine has produced antibodies

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. The representative of the research team said that the first group of vaccines in Zhejiang Province has produced antibodies. The researchers have screened Covid-19 through 4 generations. The vaccine is 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, antigens are produced by the first pre-test group. Research and development of mRNA vaccines has entered the animal testing stage, and recombinant adenovirus vaccines have begun to expand 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 been continuously researching and tracing the origin of the new strain of Corona virus, perfecting treatment regimens, developing preventive vaccines, conducting 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 the discovery and optimization of inhibitors to prevent the invasion of Covid-19.

Positive results from the first group of vaccines have increased confidence in the ability to defeat the epidemic. The Covid-19 epidemic has appeared in 30 countries and territories around the world, causing more than 77,600 infections and 2,360 deaths.
