Anhui Zhifei Xinkuan Vaccine and Kexing Xinkuan Vaccine are similarly effective in preventing the organism from contracting the Xinkuan Virus after the full course of vaccination, and there is no claim that one is better than the other. Anhui Zhifei Xinkuan vaccine is a recombinant protein subunit vaccine, the main component of which is part of the protein on the surface of the Xinkuan virus, which can stimulate the body’s immune system to produce an immune response after entering the body. Kexing XKV vaccine is an inactivated XKV vaccine, the main component of which is the fully inactivated XKV, which can also stimulate the body to produce an immune response after entering the body. The main difference between the two types of vaccines is that the basic immunization procedure of recombinant protein subunit vaccine is three doses, and the basic immunization procedure of inactivated vaccine is two doses. Both vaccines can produce good protection after full vaccination according to the corresponding procedures, and there is no one better. Vaccination should be carried out reasonably under the guidance of physicians.
