1. What is rabies vaccine? Rabies vaccine is a vaccine with a long history. The first manufacturer of rabies vaccine is Pasteur of France. In 1882, it successfully used the method of continuous passage to weaken the virulence of the virus, and used the adapted virus seed to make vaccines. The rabies vaccine made in China is inoculated into the primary hamster kidney cells with rabies virus fixed virus. After culture, the venom is harvested, concentrated, purified, refined, and added with aluminum hydroxide adjuvant. After comprehensive verification, it is a rabies vaccine.
2. Why can injecting rabies vaccine prevent rabies?
There is only one serotype of rabies virus, and the antigen properties of rabies virus around the world are the same. After the rabies vaccine is inoculated, anti rabies virus antibodies can appear in the human blood. These antibodies can prevent the direct transmission of the virus between cells, reduce the proliferation of the virus, and at the same time remove the free rabies virus, prevent the propagation and spread of the virus, so as to prevent rabies.
3. What to do after being bitten by animals?
If you are bitten by an animal (such as a dog, cat, wolf, etc.) but can't determine whether the animal is a healthy and non-toxic animal, you should go to the hospital to treat the wound in time, or you should clean the wound repeatedly and thoroughly with soap water first, so that most of the invading virus can be washed away, and then you can go to the health and epidemic prevention department to inject rabies vaccine as soon as possible. For severe bites, in addition to thorough local cleaning and disinfection, rabies serum should also be used around the wound for infiltration and injection. Then inject rabies vaccine. The bitten wound should not be bandaged and sutured, and the wound should be exposed as far as possible.
The immune effect of rabies vaccine injection is directly related to the injection time. After the bite, the earlier the injection, the better the immune effect and the greater the chance of protection.
4. What are the contraindications of injecting rabies vaccine?
Because rabies is a fatal disease, the mortality rate is almost 100%, and there is still no effective treatment in the world. Therefore, after being bitten by rabies or animals that do not know whether they are infected, rabies vaccine should be injected immediately. If a pregnant woman is bitten, she should also be injected with rabies vaccine in a timely manner.
There is no contraindication for injecting rabies vaccine.
5. After the animal bites, the skin is not injured, and only the tooth marks need to be injected with rabies vaccine?
After being bitten or scratched by animals such as dogs, cats, wolves, etc., as long as the skin is really not bitten, it is difficult for rabies virus to invade the body through intact skin, but if there are tooth marks on the skin, you cannot be careless. Sometimes, although no skin damage can be seen, in fact, tooth marks mean skin damage that is difficult to be detected by the naked eye. In this case, rabies virus may invade the human body along the tooth print. Therefore, the bitten part should be disinfected immediately, and the part with tooth marks should be thoroughly cleaned with soap water, and iodine should be smeared, and then rabies vaccine should be injected throughout the whole process.
6. Will rabies occur if rabies vaccine is not injected after being bitten by mad animals?
Rabies may not always occur if rabies vaccine is not injected after being bitten by crazy animals. Whether rabies occurs is directly related to the type of biting animal, the virulence of the virus strain, the amount of virus entering the human body, the age of the injured, the physical condition, the site of the bite, the severity of the injury, and the local treatment of the wound after the bite.
7. Is it necessary to inject the vaccine after being bitten again?
After being bitten and scratched by animals, rabies vaccine will be injected throughout the whole process. At this time, the body will produce anti rabies antibodies, but the maintenance time of this effective antibody is relatively short. If the distance between this bite and the previous vaccine injection is within 3-5 months, two more injections will be enough. If it has been more than 6 months, it should be injected again.
