Vaccination

Vaccinations are primarily intended to protect against infectious diseases caused by bacteria or viruses. The vaccine often consists of killed, attenuated or components of pathogens, whereby the vaccine is injected into the body. This immunization makes people more resistant to pathogens. A distinction is made between active and passive immunization, with passive immunization being injected as a preventative measure and active immunization being injected to support the antibodies in the event of an existing disease. In the case of active immunization, therefore, it is not versions of pathogens that are injected, but antigens, so that it "actively" develops antibodies against these antigens.
