Vaccines: a harmless form of the pathogen (a disease-causing agent may be a virus, bacteria, parasite etc) which is administered to cause an immune response before infection. After this, when people are exposed to the real pathogen, they will have a rapid immune response to it. Immunization: artificial introduction of immunity by the injection of a foreign object ( antigen in vaccine) causing the body to generate an immune response to that object. Some long term memory t and b cells remain and can divide rapidly if an infection occurs. Once exposed to antigen, memory t and b cells remember the exposure and immune response can occur faster. Once you get your vaccination, you will produce b cells making antibodies (proteins that bind to antigens) to the virus; if you are exposed after several weeks, your body can eliminate the virus (even years later). Hep b, hpv, a viral capsid protein is used) i.
