If you are bitten by an animal after receiving the rabies vaccine, you will need to receive a booster shot if the interval between shots is less than 3 to 5 months, and a full course of rabies vaccination if it is more than 6 months. The rabies vaccine is a biological agent that produces anti-rabies antibodies in the human bloodstream, which in turn prevents the virus from spreading from cell to cell, reduces the number of viruses proliferating, and removes free rabies viruses, ultimately preventing the virus from reproducing and spreading, and thus achieving the goal of preventing rabies. After full vaccination, the body will produce rabies antibodies, but these antibodies cannot achieve lifelong immunity, and the maintenance time is relatively short. If you are bitten by an animal again within 6 months after vaccination, you will need to give different numbers of booster shots depending on the severity of the bite. After 6 months or more, a full course of rabies vaccination is required. Before rabies vaccination, the wound should first be treated in a standardized manner, so it is important to visit a hospital promptly after being bitten by an animal.
