The second -generation reorganized protein vaccine of the mutant new crown virus such as Omikon Rong was approved in Mexico to conduct phase I/II clinical trials

Cover reporter Zhou Jiayi

On July 20, the cover reporter learned from the Sichuan Provincial International Medical Exchange Promotion Association that recently, the Mexican pharmaceutical supervision department has issued a license to approve the reorganized mutant new coronary virus vaccine developed by Chengdu Wesk Biomedical Co., Ltd./Sichuan University Huaxi Hospital. (SF9 cell) Carry out phase I/II clinical research. This study is a random, blind, and controlled research. The purpose of this research is to evaluate the basic immunohistic population of this product to complete the new crown vaccine, or the MRNA vaccine, or adenovirus vaccine, and strengthen the safety and immunogenicity of vaccination. Studies will recruit people who have completed the above -mentioned technical routes of the new crown vaccine basic immunization. They will conduct sequential immune clinical studies and will be completed in the recent group.

When OMICRON (Omicron) mutated strains just appeared at the end of 2021, the company quickly acted and actively promoted the study of the strains, cell matrix and process quality of the new coronary virus vaccine (SF9 cells). The Asian unit vaccine antigen can be assembled as a stable protein particles. The large -scale production of vaccines adopts international advanced insect cell protein expression technology, and cooperates with WGA01 (MF59 sample agent) that can induce more immune response.

At present, the epidemic of new coronary pneumonia is still spreading globally, and Omitron mutant BA.4 and BA.5 have become the world's major popular strains. The vaccine for Omitron mutations BA.4, BA.5 and BA.2.12.1, as well as mutation strains such as Beta (Beta), Gamma (gamma), Delta (Delta) can induce high neutralization and neutralization. The antibody titular, suggesting that the vaccine is a general -purpose new crown vaccine for a variety of mutant strains.
