Rabies vaccination does not need to be repeated within one year, as the full five doses of rabies vaccine are guaranteed to be effective for one year. If you are bitten by a rabid dog again you can check for rabies virus antibodies and if the antibodies are >0.5 U/mL there is no need to repeat the vaccination. If it is for preventive purposes, another booster shot can be given, which can provide protection for three years. Rabies is a preventable but untreatable disease, and once infected there is no cure, with a mortality rate of 100%. Therefore, after being bitten by a stray cat or rabid dog, it is important to go to the nearest vaccination station for rabies vaccination within 24 hours.
