Let's introduce the best time to inject rabies vaccine:

1. After being bitten by animals, the rabies vaccine should be injected as early as possible. The best time for the first injection of rabies vaccine is within 48 hours after being bitten. In general, rabies vaccine is divided into five times, that is, five injections are required, which are injected within 24 hours, the third day, the seventh day, the 14th day and the 30th day after being bitten.
2. If no rabies vaccine is injected within 10 days of being bitten, rabies vaccine can still be injected. If the bitten parts are sensitive parts such as head, face and neck, even after a long time, rabies vaccine injection is still required, and anti rabies immune serum or immunoglobulin injection is also required.
3. If the time of being bitten has passed for several months, it may not be necessary to inject rabies vaccine at this time, because the incubation period of rabies is generally three months (of course, the incubation period of rabies in special cases can be as long as 10 years), so it is not very meaningful to inject rabies vaccine after many years of incubation.
Through the introduction above, we can know that after being bitten or scratched by dogs or other carnivores, rabies virus enters the human body through the blood. In this case, the probability of rabies virus infection is very high. Once the rabies virus is infected, there will be fear of wind, light, water sound and muscle spasm. Therefore, after being bitten by animals, we must go to the hospital to inject rabies vaccine as soon as possible, and at the latest, we must inject rabies vaccine within 72 hours.
