Rabies antibodies generally protect the body within one year of injection, and some studies have shown that rabies antibodies above 0.5 U/mL can protect the body from the virus. After rabies vaccination, if re-exposure occurs within a certain interval of time, it is not necessary to be vaccinated again or to be vaccinated again in its entirety to ensure safety. This interval is the protection period of the rabies vaccine. In general, the first year of rabies vaccination for people will have an antibody level higher than 1 U/mL, but each person will have differences. If you are bitten by a dog again, a second booster shot is recommended, and after two booster shots, you will be protected for up to 5 months. After rabies vaccination, patients should take rest and observe for any adverse reactions. Rabies vaccine is prohibited for pre-exposure prophylaxis, people with a history of severe allergies, immunodeficiency and serious diseases. If the symptoms are not obvious, rest should be paid attention to and can be relieved by itself. If the symptoms are more serious, the patient should go to the hospital for consultation.
