The difference between lysed vaccine and inactivated vaccine is the difference in technical route and application scope, taking New Crown vaccine as an example.
First of all, the technical route is different. Fracking vaccine is mainly made by cracking the protein in the virus and then extracting it to re-compose the new crown vaccine, while inactivated vaccine is made by directly putting the inactivated new crown virus into the vaccine so as to achieve the purpose of preventing the disease, and its technical route is fundamentally different.
In addition, due to the relative complexity of the cracked vaccine program, while the inactivated vaccine program is simple, the cost difference is large, which leads to the gap in the scope of application. At present, inactivated vaccine is the main type of vaccine used for mass inoculation in China, and cracked vaccine has not yet been applied on a large scale.
