Rabies virus has two main antigens: one is the glycoprotein antigen on the outer membrane of the virus, which can bind to the acetylcholine receptor to make the virus neurotoxic, and produce neutralizing antibodies and hemagglutination inhibiting antibodies in the body, and the neutralizing antibodies have a protective effect; The other is the inner riboprotein antigen, which can make the body produce complement binding antibodies and precipitin, and has no protective effect.
