The rabies vaccine is usually okay for dogs and cats that have been vaccinated with the required amount of veterinary rabies vaccine, and during the immunization period of the vaccine, people who have been slightly bitten by dogs can just clean and disinfect the wound locally without injecting the human rabies vaccine. Dogs need rabies vaccination every year, because the effect of rabies vaccine is not permanent, usually disappears in about 1 year, and needs to be injected again.
