The rabies vaccine is administered by the five-dose method or the four-dose method, and the antibodies last for one year. After being exposed to the virus, you need to go to the nearest vaccination station within 24 hours for rabies vaccination. The World Health Organization believes that a rabies antibody concentration of more than 0.5 U/mL can help protect against rabies virus infection. Therefore, the rabies vaccine can last for one year.
