In response to virus mutation, inactivated vaccines have better broad-spectrum

According to reports, in the process of accelerating the vaccination work, the National Health Commission attaches great importance to completing the entire immunization process in accordance with the requirements of vaccination technical specifications.

Inactivated vaccines are used more in my country

Does the current new crown vaccine have any effect on virus mutation?

Zhang Yuntao, vice president of Sinopharm Group China Biology, introduced at the press conference that virus mutation is an issue that has received high attention during the development and use of vaccines.

In view of the characteristics of inactivated vaccines, Zhang Yuntao believes that inactivated vaccines contain more antigenic components of the virus, relatively speaking, have better broad-spectrum protection and better tolerance to mutations.

According to reports, in my country, the new crown vaccine with two technical routes of inactivation and viral vector has been approved for conditional marketing.

"Chinese companies are ready to develop new vaccines in response to sudden major mutations.

In addition, vaccine research and development is still in the process of intense and orderly development.
