Vaccination is a technology that vaccinates people or animals with vaccine preparation, so that the recipients can gain immunity against a specific or vaccine-like pathogen, and the immune system can identify foreign objects, screen and make antibodies, thus producing antibodies against this pathogen or similar pathogens, and then making the recipients have strong resistance to diseases.
Nowadays, the common inoculation method in medicine is injection, and the word "inoculation" comes from vaccination technology. Its original intention is different from today's usage, and there is a slight gap in the application scope of modern immunology research.

Compared with the first draft, the second draft further refines the compensation system for the abnormal reaction of vaccination, and clearly puts forward that if death or severe disability occurs after vaccination, even if the abnormal reaction of vaccination cannot be ruled out, compensation should be made.
Doctors vaccinate you to prevent diseases. This is called vaccination or vaccination. Vaccines contain harmless dead germs or substances extracted from harmless dead germs, which can make the body naturally defend against germs. After injection, the body seems to be invaded by germs and begins to produce antibodies to kill germs; The body also makes protective white blood cells, which can resist some infectious diseases. If you really encounter similar germs in the future, your body can destroy them immediately.
Vaccines can also be used for active immunotherapy. This technology stimulates the immune system to produce a large number of antibodies, or foreign corresponding antibodies, to deal with pathogens in infected patients. Rabies vaccine uses this principle, and this vaccine may also be used as a preventive vaccine. In recent years, studies on cancer and AIDS have found that the surface of diseased cells has different markers from ordinary cells, which may be suitable as the target of antibody attack to treat patients.
