The rabies vaccine is usually given as a 5-dose vaccination, and the antibody concentration is usually maintained for one year after the 5-dose vaccination. Rabies vaccination is the best measure to prevent the occurrence of rabies and is usually given as a 5-dose vaccination or a 4-dose vaccination. 5 doses are given on the day of the bite, on the 3rd day, on the 7th day, on the 14th day and on the 30th day. Antibodies in the body above 0.5 U/mL will serve to keep the virus at bay. After more than one year of rabies vaccination, it is not necessary to reinject the rabies vaccine, but only to give a booster shot, after which the person’s antibodies can quickly rise to 20 U/mL. The antibody concentration will slowly decline again and still protect for 3 years. If you are bitten by a dog again after 3 years, you will need a second booster shot. After the 3 booster shots, the rabies antibody concentration reaches a higher peak and can be maintained for 3 months. Within 24 hours after being bitten by a dog, the patient should go to a regular hospital or epidemic prevention station to receive rabies vaccine and treat the wound properly.
