The biggest difference between the neocoronavirus vaccine CHO and VERO is the different technical routes of production of the two.
New crown vaccine (cho cells) is recombinant new crown virus, is the new crown virus through the genetics of the recombination mechanism to produce a vector vaccine, which can obtain cellular immunity, but also can have antibodies and neutralizing antibodies to humoral immunity.
The New Crown vaccine (vero cells) is composed of inactivated New Crown virus, which is injected directly into the human body after inactivation of the entire virus. It mainly stimulates the human body to produce humoral immunity, and cannot stimulate the emergence of cellular immunity in the human body, and it may also lead to an adverse reaction in the human body due to the presence of other components in the entire virus.
If the new crown vaccine is injected, it should be observed for 30 minutes, and once discomfort occurs, it is necessary to communicate with the doctor in a timely manner to avoid adverse consequences.
