Received only the vaccine but not the immunoglobulin after being scratched by a cat and bleeding

It is acceptable to receive only the rabies vaccine without immunoglobulin after being scratched by a cat that caused bleeding. However, if the wound is large and there is significant bleeding, rabies immunoglobulin should be administered.

1. Immunoglobulin not required

Cats are mammals and may potentially carry the rabies virus. Being scratched by a cat constitutes Category II rabies exposure. It is essential to promptly clean and disinfect the wound and receive the rabies vaccine. After primary vaccination, neutralizing antibodies typically appear 7–10 days following the first dose, and protective antibody levels are achieved after completing the full vaccine series, lasting for at least six months. If the wound is small with only minor bleeding, administration of rabies immunoglobulin is generally unnecessary.

2. Immunoglobulin required

However, if the wound is extensive and located close to the head, receiving only the rabies vaccine may still leave a risk of infection. The rabies virus is an anaerobic virus with a certain incubation period and is commonly transmitted through broken skin or wounds. In such cases, rabies immunoglobulin should be administered to help prevent the onset of rabies.

Avoid bathing within 24 hours after receiving the rabies vaccine, and drink plenty of water. During the vaccination process, avoid consuming spicy or stimulating foods and beverages such as tobacco, alcohol, strong tea, soda, coffee, and chocolate.
