The best time to get tetanus is within twenty-four hours after the injury, and the earlier the injection, the better the effect. If the human body is stabbed or wounded by wood, iron, sharp substances, etc., and the wound appears to bleed, and the wound is thin and deep, it is easy to be infected with tetanus bacillus, and the incubation period in the human body is generally 6~12 days. If not dealt with in time, it will increase the death rate. At this time, tetanus immunization vaccine should be injected as soon as possible, and the earlier the injection the better the result. After the tetanus vaccine, it is necessary to keep the wound area clean and hygienic, avoid spicy and stimulating food, and develop good habits of work and rest. If the injection is delayed after the wound is broken, it should also be injected before the onset of the tetanus, to minimize the serious effects of tetanus infection on the human body, or even death. Specific cases need to consult your doctor for further treatment.
