After being bitten by a dog, the injection is effective within 24 hours, and it is best not to exceed 48 hours. The earlier the injection is given, the sooner specific antibodies are produced in the body and the better the immune effect is. Rabies vaccine injections have strict course and time requirements, and are divided into two types: 5-shot course and 4-shot course. The injection method of the 5-shot course is to inject one shot each on days 0, 3, 7, 14, and 28. The 4-shot course is to inject 2 shots on the same day, one shot in the left and right arms, and one shot on the 7th and 21st days. Under normal circumstances, the injection must be completed in a sufficient amount and for a sufficient course of treatment within the prescribed time to avoid affecting the immune effect.

How to avoid being bitten by a dog:

1. Don’t look into the dog’s eyes. When a dog glares at you to warn you, if you look at the dog, it may be regarded as a threat, and your warning will be regarded as invalid, causing the dog to give a more serious warning, or it may bite directly.

2. When the dog is angry, do not run or make any movements. Immediately put your feet together, stand still, cross your hands, and lower your head. Don't pay attention to your dog's barking. When it barks for a while and feels that you are no threat, it will leave.

3. Call for help loudly, which can attract the attention of people around you and bring in reinforcements so that you will not be alone. It saves a lot of trouble if the dog owner is around. With the discipline of the dog owner, you can rest assured.
