Vaccination involves introducing a weakened or inactive form of a pathogen or its antigens, stimulating an immune response that creates memory cells. This ensures a faster and stronger secondary response upon subsequent infection, quickly overcoming the pathogen.
- dead, inactive or low dose of pathogen/antigens introduced - immune response occurs - memory cells form - if pathogen reinfects, secondary immune response is greater - more antibodies produced more rapidly - infection overcome quickly
