Immunology and Vaccination Program
• Natural and adaptive immune responses are essential to maintain viability. Lack of natural immunity causes death through recurrent, uncontrollable infections.
Immunology and Vaccination Program
• Infection diseases that are not controlled also occur in the absence of adaptive immune response.
• Immunization: The mixture of antigens or antigens, the material used to induce artificial active immunity, is known as a vaccine or an immunogen, and this is called immune response production.
Active Immunity Passive Immunity Antigen exposure; obtained by injecting
immunity antigen. No exposure to antigen; immune antibodies or
It is provided by injecting antigen-reactive T cells.
Active Immunity Passive Immunity The specific response is made with
individually obtained immunity. The specific immune response is done in a secondary host.
Active Immunity Passive Immunity The immune system is activated by
antigen; immunological memory works. There is no immune system activation, no immunological memory.
Active Immunity Passive Immunity The immune response can be maintained
by stimulating memory cells. Immunity may not be maintained and decreases rapidly.
Active Immunity Passive Immunity The immune condition develops over a
period of weeks. Immunity develops immediately.
