Does a person need a shot if they were scratched by a vaccinated cat, with only minor skin breakage?

The term "injection" here refers to the rabies vaccine. Generally, if a person sustains minor skin breakage from a scratch by a cat that has been vaccinated against rabies, they should still receive the rabies vaccine. The detailed explanation is as follows:

Rabies is a zoonotic infectious disease caused by the rabies virus, primarily affecting the central nervous system. The rabies virus is an RNA virus with a bullet-like shape and can be transmitted to humans through contact with infected animals' bodily fluids via wounds or broken skin. The incubation period for rabies is typically 1 to 3 months. After infection, patients may experience atypical symptoms such as loss of appetite, fatigue, headache, and fever. Even if a cat has been vaccinated against rabies, there remains a possibility that it could carry the rabies virus. When the skin is scratched, the virus may enter the body through the wound. Therefore, individuals who sustain such injuries should immediately go to a正规 hospital to receive the rabies vaccine.

It is recommended that when interacting with small animals, proper self-protection measures should be taken to avoid being scratched or bitten. If the skin is broken, prompt medical attention is essential.
