How long does the rabies vaccine last?
Disease description:
I was scratched by a stray cat in the neighborhood this morning, but I received the rabies vaccine four months ago. I'd like to know how long the rabies vaccine usually provides protection?

Rabies vaccine typically provides effective protection for 6 months to 1 year after administration. After completing the full course of rabies vaccination, the human body produces corresponding antibodies, which offer protective immunity for at least one year. However, the exact duration varies among individuals and depends on multiple factors such as personal immune response and vaccine type. If an animal bite or scratch occurs again within the vaccine's effective period, re-vaccination is generally not required. However, if the incident happens beyond the effective period or involves a severe injury, it is recommended to seek medical attention promptly and receive appropriate booster doses. Additionally, to prevent rabies, pet owners should ensure their animals are vaccinated on schedule to reduce infection risks. Patients who receive post-exposure vaccination should rest adequately, avoid strenuous exercise, and keep the wound clean and dry to prevent infection.
