On the 9th, the first batch of Coveif’s new coronavirus inactivated vaccine independently developed by the Institute of Medical Biology of the Chinese Academy of Medical Sciences (hereinafter referred to as the Institute of Biology of the Chinese Academy of Medical Sciences) was launched for domestic emergency use, adding another weapon to my country’s fight against the new crown epidemic. The new crown inactivated vaccine continues to expand its production capacity.

It is reported that since the outbreak of the new coronavirus pneumonia, under the overall deployment of the Party Central Committee and the State Council, the Institute of Biology of the Academy of Medical Sciences has actively undertaken scientific research tasks for epidemic prevention and control, and carried out research on emergency vaccine research and development, animal model establishment, virus traceability and transmission mechanism research. Scientific research. In terms of emergency vaccines, the focus is on promoting the research and development of inactivated vaccines for the new coronavirus. At present, the research on this vaccine has achieved initial results.
Phase I/II clinical results show that the vaccine has good safety and immunogenicity. It can quickly induce systemic immune response after vaccination. The positive conversion rate of neutralizing antibody and anti-S protein antibody reached 14 days after the full course of immunization. 96% and 99.33%, can effectively provide protection.
The cross-neutralization test research carried out shows that the antibodies induced by the vaccine-immunized body have the ability to cross-neutralize the new coronavirus epidemic strains from different sources.

At present, the industrialization of the vaccine is steadily advancing, and the newly-built new crown inactivated vaccine production workshop in the Majinpu Vaccine Industrial Base of the Institute of Biology of the Academy of Medical Sciences has been officially put into use. At the same time, the expansion project of the vaccine is also under construction. It is expected to be completed and put into production by the end of the year. By then, the annual output of the vaccine will increase to 500 to 1 billion doses, adding another fire to the global fight against the new crown epidemic.
The immunization procedure of the new crown inactivated vaccine developed by the Institute of Biology of the Medical Academy is the same as that of similar vaccines, with 2 doses in the whole course, with an interval of 2-4 weeks between each dose. The current vaccination age is 18 years old and above.
