Vaccination card is a statistical means for medical prevention personnel to vaccinate children or adolescents, which can conveniently and quickly grasp the vaccination situation of children or adolescents. The contents of vaccination cards for primary and secondary school students must include gray seedlings and hemp seedlings. So that recipients can gain immunity against specific or vaccine-like pathogens.
Antibodies are produced by the immune system to identify foreign bodies, thus producing antibodies against this pathogen or similar pathogens, and then the injected people 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.

The main purpose of vaccination is to make the body produce natural biological substances, so as to improve the body's recognition and defense function against pathogens. Sometimes similar pathogens can cause an immune response against the same pathogen, so a vaccine is mainly aimed at a disease or a pathogen with high similarity. For example, smallpox vaccination is a good example.
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.
