Immunization


As for personal prophylaxis, the most reliable way to prevent an infectious disease is timely immunization. It is necessary to increase the specific resistance of the organism to various pathogens, that is, to act on immunity. Impact on immunity - immunization, which can be active and passive.
Immunity to infectious diseases is developed during the period of natural recovery of the infectious patient or with the artificial introduction of a vaccine to a healthy person. The goal of active immunization is to cause a specific immune response to a particular infectious agent-the vaccine introduced.
Vaccines are produced from killed or weakened microorganisms that cause mild forms of the disease. With a decrease in immunity, the vaccine can be administered repeatedly. Subsequent exposure to the same agent results in a rapid increase in resistance to the formation of the necessary immune cells.
With some diseases, the creation of vaccines has not yet been implemented (salmonellosis, infectious rhinitis, AIDS, etc.).
Passive immunization is the introduction of ready-made antibodies (immunoglobulin proteins that are formed in response to the introduction of microorganisms or part of them-antigen) obtained from a human or animal after active immunization. Immunity after passive immunization is short.
