The Neocoronavirus Vero vaccine may be from Kexing or Beijing Biologicals, and both companies currently produce the Neocoronavirus Vero vaccine. The New Crown Vero vaccine usually refers to the New Crown Virus inactivated vaccine, which uses Vero cells as the substrate for the New Crown Virus to multiply, and then inactivates and purifies the virus after it has multiplied to make an inactivated New Crown vaccine. At present, both Kexing Zhongwei and Beijing Biotechnology produce inactivated neocoronavirus vaccines using Vero cells as the culture vector. Both vaccines can produce an effective immune response in humans after vaccination. In addition, it is possible to receive Vero inactivated neocoronavirus vaccine from two manufacturers successively without having to receive vaccine from the same manufacturer, which usually does not affect the immunization effect of the vaccine, and the basic vaccine program as well as booster shots should be completed in a timely manner.
