The rabies vaccine is more effective when administered within 24 hours of being bitten by a cat or dog because the rabies virus enters the nervous system primarily through the subcutaneous, or broken, skin, and after entering the local nervous system, it enters the central nervous system and develops. In terms of maximum protection, rabies vaccination within 24 hours can promote the early production of rabies antibodies in the body to protect against the virus. Rabies is a malignant infectious disease with no cure and a 100% mortality rate. If you have been bitten by a rabid dog or feral cat and your skin is broken, it is recommended that you go to the nearest immunization station for rabies vaccination within 24 hours.
